The interval for which the ball's height is increasing on the graph, would be 0 seconds to 1.5 seconds.

The interval for which the ball's height is increasing is when the slope of the graph is positive, or when the height is increasing with respect to time.

Looking at the graph, we can see that the ball starts at a height of 0 meters and reaches a peak of 11.025 meters at 1.5 seconds. After 1.5 seconds, the ball begins to fall back to the ground.

Therefore, the interval for which the ball's height is increasing is from 0 seconds to 1.5 seconds. During this interval, the height of the ball is increasing as it travels upwards, reaching its peak at 1.5 seconds. After 1.5 seconds, the height of the ball starts decreasing as it falls back down to the ground.

a) The exact solutions on [0, 2π) are t = π/3, π, and 5π/3. b) The exact solution on the interval [0, π) is t = 2π/3. c) The solutions are θ = π/3 and θ = 5π/3. d) The exact solutions on the interval [0, 2π) are: t = arcsin[(-1 +  [tex]\sqrt{41}[/tex])/4] and t = 2π - arcsin[(-1 +  [tex]\sqrt{41}[/tex])/4] using trigonometric identities.

a) We can rewrite the equation as:

2[tex]cos^{2}t[/tex] + cos(t) - 1 = 0

Using the quadratic formula, we get:

cos(t) = [-1 ± [tex]\sqrt{1-4(2)(-1)}[/tex] ] / (4)

cos(t) = [-1 ± [tex]\sqrt{9}[/tex]]/4

cos(t) = [-1 ± 3]/4

Thus, we have two solutions:

cos(t) = 1/2, which gives us t = π/3 and t = 5π/3

cos(t) = -1, which gives us t = π

Therefore, the exact solutions on [0, 2π) are t = π/3, π, and 5π/3.

b) We can use the identity [tex]tan^{2}t[/tex] + 1 = [tex]sec^{2}t[/tex] to rewrite the equation as:

[tex]tan^{2}t[/tex] = - [tex](3/2)^{2}[/tex]

Taking the square root of both sides and remembering that tan(t) is negative in the third quadrant, we get:

tan(t) = -3/2

Using the identity tan(t) = sin(t)/cos(t), we can rewrite this as:

sin(t)/cos(t) = -3/2

Multiplying both sides by cos(t) and rearranging, we get:

sin(t) = -3cos(t)/2

Squaring both sides and using the identity [tex]sin^{2}t[/tex] + [tex]cos^{2}t[/tex] = 1, we get:

9[tex]cos^{2}t[/tex]/4 + [tex]cos^{2}t[/tex] = 1

Expanding and simplifying, we get:

13 [tex]cos^{2}t[/tex] /4 = 1

[tex]cos^{2}t[/tex]  = 4/13

Taking the square root of both sides and remembering that cos(t) is negative in the third quadrant, we get:

cos(t) = -2[tex]\sqrt{13}[/tex] /13

Using the identity  [tex]sin^{2}t[/tex] +  [tex]cos^{2}t[/tex]  = 1, we can solve for sin(t) as:

sin(t) = -3/2 cos(t) = 3[tex]\sqrt{13}[/tex] /13

Therefore, the exact solution on the interval [0, π) is t = 2π/3.

c) We can use the identity sin(2θ) = 2sin(θ)cos(θ) to rewrite the equation as:

sin(θ) = 2sin(θ)cos(θ)

Dividing both sides by sin(θ) (assuming sin(θ) is non-zero), we get:

1 = 2cos(θ)

cos(θ) = 1/2

Therefore, the solutions are θ = π/3 and θ = 5π/3.

d) We can use the identity cos(2t) = 1 - 2 [tex]sin^{2}t[/tex]  and rearrange the equation as:

2 [tex]sin^{2}t[/tex]  + sin(t) - 5 = 0

Solving this quadratic equation using the quadratic formula, we get:

sin(t) = [-1 ± [tex]\sqrt{41}[/tex]]/4

Since the sine function has a range of [-1, 1], only the positive solution is possible, so we have:

sin(t) = (-1 + [tex]\sqrt{41}[/tex])/4

Using the identity [tex]cos^{2}t[/tex] = 1 -  [tex]sin^{2}t[/tex] , we can solve for cos(t) as:

cos(t) =[tex]\sqrt{1-sin^{2}t}[/tex] = [tex]\sqrt{17-\sqrt{41} }/4[/tex]

Therefore, the exact solutions on the interval [0, 2π) are:

t = arcsin[(-1 +  [tex]\sqrt{41}[/tex])/4] and t = 2π - arcsin[(-1 +  [tex]\sqrt{41}[/tex])/4]

The approximate value of P(adult ∣ rode a ferris wheel) is 0.6364, which is approximately 63.64%.

To find the approximate value of P(adult|rode a ferris wheel), we can use the conditional probability formula:

[tex]\mathrm{P(adult | rode\ a\ ferris\ wheel) = \frac{P(adult \ and \ rode \ a \ ferris \ wheel)}{P(rode \ a \ ferris \ wheel)} }[/tex]

From the data given in the table, you can see that:

Total number of people who rode the ferris wheel: 198 (children + adults)

Number of adults who rode the ferris wheel: 126.

So, P(rode a ferris wheel) = 198/264

And, P(adult and rode a ferris wheel) = 126/264

Now plug these values into the conditional probability formula:

​[tex]\mathrm{P(adult | rode\ a\ ferris\ wheel) = \frac{P(adult \ and \ rode \ a \ ferris \ wheel)}{P(rode \ a \ ferris \ wheel)} } \\\\= \frac{126/264}{198/264}[/tex]

[tex]\mathrm{P(adult | rode\ a\ ferris\ wheel) } = \frac{126}{198} \\\\ \approx 0.6364[/tex]

The man is 23 km west of his home after driving 169 km to the east and 192 km to the west.

To determine how far the man is from his home after driving 169 km to the east and 192 km to the west, we can think of his movements as a displacement vector.

The vector representing the man's movement to the east has a magnitude of 169 km and is directed towards the east. Similarly, the vector representing his movement to the west has a magnitude of 192 km and is directed towards the west.

Since these two vectors are in opposite directions, we can subtract them to find the net displacement vector.

Net displacement = 169 km east - 192 km west

= -23 km west

The negative sign indicates that the net displacement vector is directed towards the west, which means that the man is 23 km west of his home.

To determine the distance between the man and his home, we can use the Pythagorean theorem. Since the man moved only in the east-west direction, the distance between him and his home is the absolute value of the net displacement, which is 23 km.

a). The difference between the two population means is estimated at a location to be 2.7.

b). 49 different possible outcomes make up the t distribution. The margin of error at 95% confidence is 1.7.

c). The range of the difference between the two population means' 95% confidence interval is (0.0, 5.4).

d). The (0.0, 5.4) represents the 95% confidence interval for the difference among the two population means.

The variability or spread in a set of data is commonly measured by the standard deviation. The deviation between the values in the data set and the mean, or average, value, is measured. A low standard deviation, for instance, denotes a tendency for data values to be close to the mean, whereas a high standard deviation denotes a larger range of data values.

Using the equation [tex]x_1-x_2[/tex], we can determine the point estimate of the difference between the two population means. In this instance, we calculate the point estimate as 2.7 by taking the mean of Sample

[tex]1(x_1=22.8)[/tex] and deducting it from the mean of Sample [tex]2(x_2=20.1)[/tex].

With the use of the equation [tex]df=n_1+n_2-2[/tex], it is possible to determine the degrees of freedom for the t distribution. In this instance, the degrees of freedom are 49 because [tex]n_1[/tex] = 20 and [tex]n_2[/tex] = 30.

We must apply the formula to determine the margin of error at 95% confidence [tex]ME=t*\sqrt[s]{n}[/tex].

The sample standard deviation (s) is equal to the average of [tex]s_1[/tex] and [tex]s_2[/tex] (3.4), the t value with 95% confidence is 1.67, and n is equal to the

average of [tex]n_1[/tex] and [tex]n_2[/tex] (25). When these values are entered into the formula, we get [tex]ME=1.67*\sqrt[3.4]{25}=1.7[/tex].

Finally, we apply the procedure to determine the 95% confidence interval for the difference between the two population means [tex]CI=x_1-x_2+/-ME[/tex].

The confidence interval's bottom limit in this instance is [tex]x_1-x_2-ME2.7-1.7=0.0[/tex] and the upper limit is [tex]x_1+x_2+ME=2.7+1.7=5.4[/tex].

The technique being described is random sampling without replacement, which is option a.

This technique is called "sampling without replacement."

However, you've also mentioned convenience sampling, which is a different method.

Let me briefly explain both concepts.

Sampling without replacement is a method in which each item, score, event, or participant is chosen from the population and is not returned to the pool for further selections.

This ensures that each element can only be selected once, eliminating the chance of duplication in the sample.

This method is often used in surveys, experiments, and research to maintain the independence of observations and provide a more accurate representation of the population.
Select an item, score, event, or participant from the population.
Record the selected item and remove it from the population.

Repeat steps 1-2 until the desired sample size is obtained.
Convenience sampling, on the other hand, is a non-probability sampling method where researchers select participants based on their accessibility and ease of recruitment.

This approach may introduce bias and limit the generalizability of the study results, as it does not ensure that the sample is representative of the population.
Identify the target population.
Recruit participants who are easily accessible and willing to participate.
Collect data from the selected participants.
In summary, sampling without replacement is a technique that prevents the same item from being selected more than once, while convenience sampling is an approach that focuses on selecting participants based on their accessibility. Both methods serve different purposes in research and should be chosen based on the study's objectives and available resources.

The Wigwam Motel in Holbrook, Arizona is famous for its large tepees shaped like cones. the floor space inside each tepee is approximately 153.94 square feet.

(a) To find the slant height of the tepee, we can use the Pythagorean theorem. The slant height is the hypotenuse of a right triangle with the height and the radius of the base as the legs.

The radius of the base is half of the diameter, so r = 14/2 = 7 feet. The height of the tepee is 32 feet. Let's call the slant height "s".

Using the Pythagorean theorem, we have:

s² = r² + h²

s² = 7² + 32²

s² = 49 + 1024

s² = 1073

s = sqrt(1073)

s ≈ 32.77 feet

Therefore, the slant height of the tepee is approximately 32.77 feet.

(b) To find the floor space inside the tepee, we need to calculate the area of the circular base. The formula for the area of a circle is A = πr², where A is the area and r is the radius.

A = π(7)²

A = 49π

A ≈ 153.94 square feet

We will use the "Either of the rules" to calculate the probability that either the top card is the ace of spades or the bottom card is the ace of spades.

The either of the rules states that the probability of either of two mutually exclusive events occurring is the sum of their individual probabilities. In this case, the events are the top card being the ace of spades and the bottom card being the ace of spades. Since the two events are mutually exclusive (the ace of spades cannot be both at the top and at the bottom of the deck), we can add their probabilities to get the total probability.

The probability of the top card being the ace of spades is 1/52 (since there is only one ace of spades in the deck of 52 cards), and the probability of the bottom card being the ace of spades is also 1/52 (assuming that the deck has been sufficiently shuffled). Therefore, the probability of either the top card or the bottom card being the ace of spades is:

P(top or bottom is ace of spades) = P(top is ace of spades) + P(bottom is ace of spades)

= 1/52 + 1/52

= 2/52

= 1/26

So the chance that either the top card is the ace of spades or the bottom card is the ace of spades is 1/26 or approximately 0.038 or 3.8%.

To find the chance that the top card is the ace of spades or the bottom card is the ace of spades, you will use the

Addition rule.

Calculate the probability of the top card being the ace of spades:

There are 52 cards in a deck, and 1 ace of spades, so the probability is 1/52.

Calculate the probability of the bottom card being the ace of spades:

This is also 1/52 since there's still 1 ace of spades among the 52 cards.

Apply the Addition rule:

Add the probabilities together, then subtract the probability of both events happening at the same time (which is 0, as

the ace of spades can't be in both positions).

Jordan studied for 2 ¼ hours on Saturday and 1 ½ hours on Sunday for his science test. To find the total number of hours he studied, we can add these two amounts.

2 ¼ hours is the same as 2 + ¼ hours, or 2 hours and 15 minutes.

So, we have:

2 hours and 15 minutes (Saturday) + 1 hour and 30 minutes (Sunday)

To add these two amounts, we can first add the hours and then add the minutes separately.

2 hours + 1 hour = 3 hours

15 minutes + 30 minutes = 45 minutes

Therefore, Jordan spent a total of 3 hours and 45 minutes studying for his science test this weekend.

Answer:

16

Step-by-step explanation:

To round 15.98 to the nearest tenth, we look at the digit in the hundredths place which is 8. Since 8 is greater than or equal to 5, we round up the digit in the tenths place which is 9. Therefore, rounding 15.98 to the nearest tenth gives us 16.

Answer:

16

Step-by-step explanation:

15 . 98

8 round up is 10

0.10 + 0.9 = 1

15 + 1 = 16

The ratio of the areas of two similar polygons is equal to the square of the ratio of their corresponding side lengths. Since the scale factor of the polygons is 3:8, the ratio of their corresponding side lengths is 3/8. Therefore, the ratio of their areas is (3/8)^2 = 9/64.

The ratio of the areas of two similar circles is equal to the square of the ratio of their radii. Since the scale factor of the circles is 2:3, the ratio of their radii is 2/3. Therefore, the ratio of their areas is (2/3)^2 = 4/9. Since the area of the larger circle is 64π, the area of the smaller circle is (4/9) * 64π = 28.44π.

The ratio of the areas of two similar polygons is equal to the square of the ratio of their corresponding side lengths. Since the ratio of the areas of the two regular pentagons is 150√3/54√3 = 25/9, the ratio of their corresponding side lengths is the square root of the ratio of their areas, which is √(25/9) = 5/3. Therefore, the ratio of their perimeters is 5:3, since the perimeters of regular polygons are directly proportional to their side lengths.

The coordinates of the point which is an outlier would be ( 14, 13).

The correlation between the 13 British towns is Linear.

The number of hours of sunshine for the British town with the maximum of 17.4 degrees Celsius is 13 hours of sunshine.

The coordinates of the outlier would be ( 14, 13). This is because, that point on the graph is far from the other points and does not follow their correlation.

The rest of the towns seem to be increasing in the same direction so they are linear.

The number of hours of sunshine in the British town with the maximum temperature of 17.4 degrees Celsius, based on the line of best fit drawn, would be 13 hours of sunshine.

Given the integer data set containing 11, 13, 15, 17, x, and y, we know that the mode, median, and mean form an increasing arithmetic sequence.

Since the mode is the unique number that appears most frequently, either x or y must be equal to one of the existing numbers (11, 13, 15, or 17). Let's assume x is the mode. For the sequence to be increasing, the mode must be the smallest, so x = 11.

The median of the data set is the average of the two middle numbers when they are arranged in ascending order. With x = 11, the sorted sequence will be 11, 11, 13, 15, 17, and y. The median will be the average of 11 and 13, which is 12.

For the mean, we have (11+11+13+15+17+y)/6. We know the mean is greater than the median, which is 12. If we increase the mean to 13, we can solve for y:

(11+11+13+15+17+y)/6 = 13
67 + y = 78
y = 11

However, this would make the mode 11 as well, so it doesn't meet the unique requirement. Let's increase the mean to 14 and solve for y:

(11+11+13+15+17+y)/6 = 14
67 + y = 84
y = 17

Now, the mode, median, and mean are unique and form an increasing arithmetic sequence (11, 12, 14). Therefore, the greatest possible value of y is 17.
