Alice’s chicken coop (cage) has a total volume of 1,472 cubic feet (ft3). Use the fact that 1 foot is approximately equal to 0.3048 m to convert this volume to m3. Round your answer to the nearest tenth.

Answer:

0.0376 or 3.76%.

Step-by-step explanation:

The probability of drawing a red marble on the first draw is 5/21 because there are 5 red marbles out of 21 total marbles in the bag.

After the first draw, there are only 20 marbles left in the bag, so the probability of drawing a red marble on the second draw, without replacement, is 4/20 or 1/5.

Similarly, after the second draw, there are only 19 marbles left in the bag, so the probability of drawing a red marble on the third draw, without replacement, is 3/19.

To find the probability of all three marbles being red, we need to multiply the probabilities of each individual draw together:

(5/21) x (1/5) x (3/19) = 15/399 or approximately 0.0376.

Therefore, the probability of drawing three red marbles in a row, without replacement, is about 0.0376 or 3.76%.

Answer:

Step-by-step explanation:

To express 799 cm² as a fraction of 0.13 m², we need to convert the units of one of the areas so that they are both in the same units.

1 cm = 0.01 m (since there are 100 cm in 1 meter)

So, we can convert 799 cm² to m² by dividing by (100 cm/m)²:

799 cm² = (799/10000) m²

Now, we can express 799 cm² as a fraction of 0.13 m²:

(799/10000) m² ÷ 0.13 m² = (799/10000) ÷ 0.13

Simplifying this fraction, we get:

(799/10000) ÷ 0.13 = 0.0799 ÷ 0.13

= 0.6138461538

Therefore, 799 cm² is equal to approximately 0.6138 of 0.13 m², or we can say:

799 cm² = (0.6138/1) × 0.13 m²

So, we can express 799 cm² as a fraction of 0.13 m² as:

799 cm² = 0.6138 × 0.13 m² (approximately)

or

799 cm² = 6138/10000 × 0.13 m²

or

799 cm² = 6138/100000 × m².

Answer: the positive value of tan(1/2x) in simplest radical form with a rational denominator is √(2/3).

Step-by-step explanation:

Using the half-angle formula for tangent, we have:

tan(1/2x) = ±√((1-cos(x))/(1+cos(x)))

Substituting cos(x) = 1/5, we get:

tan(1/2x) = ±√((1-1/5)/(1+1/5))

= ±√(4/6)

= ±√(2/3)

Since we are looking for the positive value, we have:

tan(1/2x) = √(2/3)

Therefore, the positive value of tan(1/2x) in simplest radical form with a rational denominator is √(2/3).

Answer:

Step-by-step explanation:

sin(x)=sqrt(24)/5=2*sqrt(6)/5

tan(x/2)=sin(x)/(1+cos(x))

Therefore, Sam wrote a total of 38,789 digits. Therefore, the probability that Sam chooses a 0 is approximately 0.026. So the sum of all the digits in the numbers from 1000 to 9999 is: 4500.

In mathematics, probability is a measure of the likelihood or chance of an event occurring. It is a way of quantifying uncertainty and expressing how likely it is that a particular outcome will occur. Probability is calculated by dividing the number of outcomes that satisfy a certain condition (such as rolling a six) by the total number of possible outcomes. Probability theory is used in a wide range of fields, including mathematics, statistics, physics, engineering, economics, and social sciences. It is used to model and analyze random phenomena, make predictions, and estimate the likelihood of certain outcomes.

Here,

(a) Sam writes down all the positive integers from 1 to 9999, inclusive. To find the total number of digits Sam wrote, we can count the number of digits in each number and add them up.

Numbers from 1 to 9 have one digit each, so there are 9 numbers with one digit, for a total of 9 digits.

Numbers from 10 to 99 have two digits each, so there are 90 numbers with two digits, for a total of 180 digits.

Numbers from 100 to 999 have three digits each, so there are 900 numbers with three digits, for a total of 2700 digits.

Numbers from 1000 to 9999 have four digits each, so there are 9000 numbers with four digits, for a total of 36000 digits.

Adding up these totals gives:

9 + 180 + 2700 + 36000 = 38789

Therefore, Sam wrote a total of 38,789 digits.

(b) Since Sam chose the digits 1 to 9999, there are 4 digits (0, 1, 2, and 3) that can appear in the thousands place, and 10 digits (0 to 9) that can appear in each of the other three places.

Therefore, the probability of choosing a 0 at random is the number of times 0 appears in the numbers divided by the total number of digits written down.

0 appears as the last digit in 1000 numbers (from 10 to 9990), and as the first digit in 9 numbers (1000, 10000, 2000, 20000, 3000, 30000, 4000, 40000, and 5000). So the total number of times 0 appears is 1000 + 9 = 1009.

The total number of digits Sam wrote is 38,789, so the probability of choosing a 0 at random is:

1009/38789 ≈ 0.026

Therefore, the probability that Sam chooses a 0 is approximately 0.026.

(c) We can find the sum of all the digits Sam wrote by adding up the sum of the digits in each number from 1 to 9999.

The sum of the digits in the numbers from 1 to 9 is 1+2+3+4+5+6+7+8+9=45.

The sum of the digits in the numbers from 10 to 99 can be found by observing that each of the digits from 0 to 9 appears in the tens place the same number of times (that is, 10 times each). Since there are 90 two-digit numbers, each digit appears a total of 10 x 90 = 900 times in the tens place. So the sum of the digits in the tens place is:

900(0+1+2+3+4+5+6+7+8+9) = 45,000

Similarly, each of the digits from 0 to 9 appears in the hundreds place the same number of times (that is, 100 times each). So the sum of the digits in the hundreds place is:

100(0+1+2+3+4+5+6+7+8+9) = 4500

Finally, each of the digits from 0 to 9 appears in each of the four places (thousands, hundreds, tens, and ones) the same number of times (that is, 1000 times each). So the sum of all the digits in the numbers from 1000 to 9999 is: 4500.

Answer:

So, if we sell 150 flowers total, we can purchase 100 daisies and 50 roses for exactly $300.

Step-by-step explanation:

Let R be the number of roses and D be the number of daisies.

Now we can set the following equations to represent the cost and the total number of flowers,

Cost equation=3.50R + 1.25D

                       = 300

Number of flowers equation= R + D

                                              = 150

We need to find the number of roses and daisies that we can purchase, as according to question the total number of flowers is 150. To find R, we can put value of  the number of flowers in the equation for R in terms of D, and also put this expression for R in the cost equation,

R = 150 - D

3.50R + 1.25D

= 300

3.50(150 - D) + 1.25D

= 300

525 - 3.50D + 1.25D

= 300

-2.25D = -225

D = 100

Therefore, we can buy 100 daisies and the remaining 50 flowers must be roses.

The cost of 100 daisies is 100 × 1.25

= $125

The cost of 50 roses is 50 × 3.50

= $175.

Therefore, the total cost is $125 + $175

= $300.

So, if we sell 150 flowers total, we can purchase 100 daisies and 50 roses for exactly $300.

Answer:

w = 105° because 180 - (45 + 60) = 75 and 180 - 75 = 105.

Step-by-step explanation:

To find w, we first need to find z.

We can find z by setting up an equation. As we know, all angles in a triangle will add up to 180, we can say that z + 45 + 60 = 180.

We can also rewrite this as 180 - 45 - 60 = z, or 180 - (45 + 60) = z.

Solving this, we get z = 75.

We can also see that w and z are supplementary angles, meaning they will add up to 180.

Therefore, we can come to the conclusion that w + 75 = 180, or 180 - 75 = w.

Solving this we get:

w = 105

Therefore, w = 105°.

If a = 9 and c = 9, the length of b is 3√18.

Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.

Given is a right angled triangle with the given length of base and altitude.

Length of base = 9

Length of altitude = 9

We have to find b, which is the hypotenuse.

Using Pythagoras theorem,

Hypotenuse² = Base² + Altitude²

b² = a² + c²

b² = 9² + 9²

b² = 81 + 81

b² = 162

b = √162 = √(18×9) = 3√18

Answer:

The net profit would be 26-18=6 dollars per hour.

we need hours such that 8h≥264 =>h≥33 hours

Answer: To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:

A = the amount of money after the given time period

P = the principal (starting amount)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time period (in years)

In this case, the principal is $6500, the annual interest rate is 2.8% (or 0.028 as a decimal), and the interest is compounded monthly (so n = 12). We want to find the amount after 2 years, so t = 2.

Plugging these values into the formula, we get:

A = 6500(1 + 0.028/12)^(12*2)

A ≈ $7,107.08

Therefore, the amount of money after 2 years is approximately $7,107.08.

13.5

Step-by-step explanation:

If y and x have a proportional relationship, we can write this relationship as:

y = kx

where k is the proportionality constant.

To find the value of k, we can use the information that "y = 9 when x = 2":

9 = k(2)

Solving for k, we get:

k = 9/2

Now we can use this value of k to find the value of y when x = 3:

y = (9/2)(3) = 27/2 = 13.5

Therefore, the value of y when x = 3 is 13.5.

Where, m = (y₂ - y₁) / (x₂ - x₁)

Now, For the line passes through (0, 2.5) and (1, 4).

Equation of line is.

⇒ y - 2.5 = (4 - 2.5) / (1 - 0) (x - 0)

⇒ y - 2.5 = 1.5x

⇒ y = 1.5x + 2.5

Hence, It cannot represent a proportional relationship.

For the line passes through (0, 0) and (4, 1).

Equation of line is.

⇒ y - 0 = (1 - 0) / (4 - 0) (x - 0)

Hence, It represent a proportional relationship.

For the line passes through (0, - 1) and (1, - 1).

Equation of line is.

⇒ y - (- 1) = (- 1 - (- 1)) / (1 - 0) (x - 0)

⇒ y + 1 = 0

Hence, It cannot represent a proportional relationship.

For the line passes through (0, 3) and (1, - 2).

Equation of line is.

⇒ y - 3 = (- 2 - 3) / (1 - 0) (x - 0)

Find the missing term in the sequence 5, 11, 17, ?, 31, 41.

Randy had 20 touchdown passes and his deviation from the mean is 5.

The standard deviation is a metric that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability. When data points are closely spaced from the mean, there is a small variation, and when they are far spaced from the mean, there is a large variation. The standard deviation determines how much the values deviate from the mean. The most popular way to assess dispersion is standard deviation, which is based on all values.

Given that, mean touchdown passes=15.

Randy's touch down passes = 20.

The deviation of the touch down passes = 20 - 15 = 5.

Hence, his deviation from the mean is 5.
