C 2.3
D 2.5

Answer:

A. They have different y-intercepts but the same end behavior.

Step-by-step explanation:

From the shape of f we see that its a descending exponential  fnction, so the  factor taken to the power x will be a fraction,  and from the points the eqation is

f(x) = 2(1/4)^x + 2

and the y-intercept is 4

g(x) has y-intercept of 4(1/4)^0 + 2 = 6  so they are different.

As x approaches infinity  both  f and g approach 2 so the end behavior s the same.

Answer:

After comparing the data, a measure of variability for both sets of data to  be utilised to find the place with the most stable temperature: C. Range, because Sunny Town is skewed.

Skewness is a measure of the asymmetry of a box plot (box-and-whisker plot) or histogram in mathematics, and as such, a box plot (box-and-whisker plot) or histogram has a normal distribution when it is symmetrical.

We may rationally establish that Sunny Town's box plot (box-and-whisker plot) is distorted by closely inspecting it.

Conversely, the Desert Landing box plot (box-and-whisker plot) is symmetrical (vertical line dividing the box into two equal halves), which simply means that both whiskers on either side of the box plot (box-and-whisker plot) are roughly equal and symmetric.

Number of clients who do not play either the piano or the guitar is 22

To find the number of clients who do not play either instrument, we need to subtract the number of clients who play either the piano or the guitar or both from the total number of clients.

Let A be the set of clients who play the piano, and B be the set of clients who play the guitar. Then, we can use the formula A union B

|A ∪ B| = |A| + |B| - |A ∩ B|

where |A ∪ B| is the number of clients who play either the piano or the guitar or both, |A| is the number of clients who play the piano, |B| is the number of clients who play the guitar, and |A ∩ B| is the number of clients who play both instruments

Substituting the given values, we get

|A ∪ B| = 46 + 58 - 17

|A ∪ B| = 87

Therefore, the number of clients who do not play either instrument is:

The solution to the system by elimination is (-2, 4).

To solve the system using elimination, we need to eliminate one of the variables by multiplying one or both of the equations by a constant.

-6X = 18 - Y

9 = -3X - 8Y

Rewrite as

-6X = 18 - Y

3X = 9 - 8Y

So, we have

-6X = 18 - Y

6X = 18 - 8Y

Now we can add this equations to the second equation to eliminate x:

0 = 36 - 9Y

This gives

9Y = 36

So, we have

Y = 4

Recall that

-6X = 18 - Y

So, we have

-6X = 18 - 4

So, we have

-6X = 12

What is Complementary angle?

Two angles are said to be complementary if their addition is 90°.Let if one angle is x then the other angle will be 90° – x. Hence, we use these complementary angles for trigonometry ratios, where one ratio is complementary to another ratio by 90 degrees such as,

[tex]sin(x) = \cos(\frac{\pi}{2} - x) \\ \tan(x) = \cot(\frac{\pi}{2} - x) \\ \sec(x) = \csc(\frac{\pi}{2} - x) \\ \cos(x) = \sin(\frac{\pi}{2} - x) \\ \cot(x) = \tan(\frac{\pi}{2} - x) \\ \csc(x) = \sec(\frac{\pi}{2} - x)[/tex]

Given, here x and y are complementary.

So, we can say that

[tex]x + y = {90}^{o} \\ y = {90}^{o} - x[/tex]

So,

[tex] \sin( x) = \frac{12}{13} \\ \sin( {90}^{o} - y) = \frac{12}{13} \\ \cos(y) = \frac{12}{13} [/tex]

The equation of line passes through the point (2, -2) and is perpendicular to the line represented by y=2/5x+2 is y = -5x/2+3

Given that a line is passing through the point (2, -2) and is perpendicular to the line y = 2x/5+2, we need to find the equation of the line,

The equation of line is, y = mx + c, where m is the slope,

So, we know that the slopes of the perpendicular lines are negative reciprocal of each other,

So, the slope of the required line is -5/2.

Therefore, the equation will be

y = -5x/2 +c

To find c put x = 2, y = -2

-2 = -5(2)/2 + c

-2 = -5 + c

c =3

Hence, the equation is, y = -5x/2+3

Answer:

18.62π square inches

Step-by-step explanation:

To find the surface area of the cylinder, we need to find the area of each of its components and add them together. We can use the net of the cylinder to visualize its components and dimensions.

First, let's find the area of the top and bottom circles. We know the diameter of each circle is 3.8 inches, so the radius is half of that, or 1.9 inches. The formula for the area of a circle is A = πr^2, so:

A(top and bottom circles) = 2π(1.9 in)^2

= 2π(3.61 in^2)

= 7.22π in^2

Next, let's find the area of the curved surface of the cylinder. The height of the cylinder is labeled as 3 inches, which is also the height of the rectangle in the net. The length of the rectangle is the circumference of one of the circles, which is πd (where d is the diameter). So:

length of rectangle = π(3.8 in) = 11.96 in

The formula for the area of the curved surface of a cylinder is A = 2πrh, where r is the radius and h is the height. We can use the radius we found earlier and the height of 3 inches to calculate the area of the curved surface:

A(curved surface) = 2π(1.9 in)(3 in)

= 11.4π in^2

Finally, we can add the areas of the top and bottom circles and the curved surface to get the total surface area of the cylinder:

Total surface area = A(top and bottom circles) + A(curved surface)

= 7.22π in^2 + 11.4π in^2

= 18.62π in^2

Therefore, the surface area of the cylinder in terms of π is 18.62π square inches.

The baseball team won 60% of the games they played.

Step-by-step explanation:

To find the percentage of games the baseball team won, we can use the following formula:

percentage = (wins / total games) x 100

where wins is the number of games won and total games is the total number of games played.

Substituting the given values, we get:

percentage = (9 / 15) x 100

percentage = 0.6 x 100

percentage = 60%

Therefore, the baseball team won 60% of the games they played.

Answer:

60%

Step-by-step explanation:

9 out of 15, written in *fraction form* is 9/15, when reduced down,  9/15 becomes 3/5. When you insert 3/5 into a calculator you get 0.6 . Since percentage is based off a x/100, you move the decimal point of 0.6 over 2 units to the right, you get 60, so it would in final would be 60/100 which equals 60%

Answer:

[tex]2\sqrt{65}[/tex] cm, decimal form is about 16.1 cm

Step-by-step explanation:

Use the pythagorean theorem:

A^2 + B^2 = C^2

A and B are legs, c is hypotenuse

First leg is 16, second leg is 2

Plug it in:

16^2 + 2^2 = hypotenuse^2

256 + 4 = hypotenuse ^2

260 = h^2

[tex]\sqrt[2]{260}[/tex] = h

To simplify the square root of 260, we can factor 260 into its prime factors:

260 = 2 x 2 x 5 x 13

Then, we can take out the pairs of identical factors from under the square root symbol:

sqrt(260) = sqrt(2 x 2 x 5 x 13)

The total number of possible outcomes when flipping a coin 8 times is 2^8 = 256.

a. To get exactly 6 heads, we need to choose 6 out of the 8 flips to be heads, and the remaining 2 flips to be tails. The number of ways to choose 6 out of 8 is given by the binomial coefficient (8 choose 6) = 28. Therefore, there are 28 possible outcomes with exactly 6 heads.

b. To get at least 3 heads, we need to count the number of outcomes with 3, 4, 5, 6, 7, or 8 heads. Using the same logic as part (a), we can count the number of outcomes with each of these numbers of heads and add them up to get the total number of outcomes with at least 3 heads.

Number of outcomes with 3 heads: (8 choose 3) = 56

Number of outcomes with 4 heads: (8 choose 4) = 70

Number of outcomes with 5 heads: (8 choose 5) = 56

Number of outcomes with 6 heads: (8 choose 6) = 28

Number of outcomes with 7 heads: (8 choose 7) = 8

Number of outcomes with 8 heads: (8 choose 8) = 1

Total number of outcomes with at least 3 heads = 56 + 70 + 56 + 28 + 8 + 1 = 219.

c. To get at most 6 heads, we need to count the number of outcomes with 0, 1, 2, 3, 4, 5, or 6 heads. Using the same logic as part (b), we can count the number of outcomes with each of these numbers of heads and add them up to get the total number of outcomes with at most 6 heads.

Number of outcomes with 0 heads: (8 choose 0) = 1

Number of outcomes with 1 head: (8 choose 1) = 8

Number of outcomes with 2 heads: (8 choose 2) = 28

Number of outcomes with 3 heads: (8 choose 3) = 56

Number of outcomes with 4 heads: (8 choose 4) = 70

Number of outcomes with 5 heads: (8 choose 5) = 56

Number of outcomes with 6 heads: (8 choose 6) = 28

Total number of outcomes with at most 6 heads = 1 + 8 + 28 + 56 + 70 + 56 + 28 = 247.

d. To get at most 2 heads, we need to count the number of outcomes with 0, 1, or 2 heads. Using the same logic as parts (b) and (c), we can count the number of outcomes with each of these numbers of heads and add them up to get the total number of outcomes with at most 2 heads.

Number of outcomes with 0 heads: (8 choose 0) = 1

Number of outcomes with 1 head: (8 choose 1) = 8

Number of outcomes with 2 heads: (8 choose 2) = 28

Total number of outcomes with at most 2 heads = 1 + 8 + 28 = 37.

b) If one parent is homozygous recessive for A, homozygous dominant for B, heterozygous for C, and homozygous dominant for D, and the other parent is heterozygous for A, homozygous dominant for B, homozygous dominant for C, and heterozygous for D.

The probability of this happening is  1/32.

To solve this problem, we need to use the principles of probability and Punnett squares.

For a tetrahybrid cross, we need to consider the four genes independently and combine the probabilities of each gene's alleles.

Assuming that A, B, C, and D are dominant alleles, and a, b, c, and d are recessive alleles, we can create a Punnett square for each gene, which would look like this:

A  |  A  |  a  |  a  

---|-----|-----|----

B  |  B  |  b  |  b  

---|-----|-----|----

C  |  C  |  c  |  c  

---|-----|-----|----

D  |  D  |  d  |  d  

Each box in the Punnett square represents a possible combination of alleles from the two parents.

For example, the top-left box represents offspring that inherit an A allele from the mother and an A allele from the father.

We can use these Punnett squares to calculate the probabilities of each genotype in the F2 offspring.

AABBCCDD - This genotype can only be produced if both parents are homozygous dominant for all four genes.

The probability of this happening is [tex](1/2)^4 = 1/16[/tex] , since each parent would need to contribute a dominant allele for each gene.

a) If both parents are homozygous dominant for A and B, heterozygous for C, and homozygous dominant for D.

b) If one parent is homozygous dominant for A and B, heterozygous for C, and homozygous dominant for D, and the other parent is heterozygous for A and B, homozygous dominant for C, and heterozygous for D.

The probability of this happening is[tex]2 * (1/2)^4 * 1/2 * 1/2 * 1/2 = 1/32[/tex]

AaBbCcDd - This genotype can be produced in 16 ways, since each gene can be inherited in two different ways (dominant or recessive).

b) If one parent is homozygous recessive for A, homozygous dominant for B, heterozygous for C, and homozygous dominant for D, and the other parent is heterozygous for A, homozygous dominant for B, homozygous dominant for C, and heterozygous for D.

The probability of this happening is [tex]2 * (1/2)^4 * 1/2 * 1/2 * 1/2 = 1/32.[/tex]

To write the equation of the line that represents Calvin’s spending on candy, we need to first find the slope and the y-intercept of the line.

We can use the two points given in the problem: (4, 28) and (10, 25)

Slope (m) = (y2 - y1) / (x2 - x1)

= (25 - 28) / (10 - 4)

= -3/6

= -1/2

The slope represents the rate at which Calvin is spending money on candy.

Now, we can use the point-slope form of the equation of a line to find the equation of the line.

y - y1 = m(x - x1)

y - 28 = (-1/2)(x - 4)

y - 28 = (-1/2)x + 2

y = (-1/2)x + 30

Therefore, the equation of the line that represents Calvin’s spending on candy is y = (-1/2)x + 30.

Answer: Equation that represents his spending on candy- y = (³⁄₁₀) x
