Answer:

A. y = 9√3

Step-by-step explanation:

The relationship of the sides of the triangles are as follows:

First leg = x

Second leg = x√3

Hypotenuse = 2x

Since we know the first leg is 9, multiply that by √3.

Therefore, y = 9√3.

The prime factors of 6 are 2 and 3. So for a number to be divisible by 6,it must also be divisible by 2 and 3.Therefore,we need to check if a number is even and then check if the sum of the digits is divisible by 3

Suppose we take two different random samples from the same population of test scores. The population mean and standard deviation

Leto [7]

Answer:

The 95% confidence interval obtained with a sample size of 64 will give greater precision.

Step-by-step explanation:

We are given the following in the question:

A 95% confidence interval is calculated with the following sample sizes

$n_1 = 25\\n_2 = 64$

The population mean and standard deviation are unknown.

Effect of sample size on confidence interval:

As the sample size increases the margin of error decreases.
As the margin of error decreases the width of the confidence level decreases.
Thus, with increased sample size the width of confidence level decreases.

If we want a confidence interval with greater precision that is smaller width, we have to choose the higher sample size.

Thus, the 95% confidence interval obtained with a sample size of 64 will give greater precision.

The height of a parallelogram is three times its base. If the area is 972 square inches, what is the base and height?

Fed [463]

So h is 3x
b is x
3x plus x equal 972
4x = 972
243 is base
243 times 3 is 729

Can someone solve this

Gemiola [76]

Answer:

f(h(-1)) = -1

Step-by-step explanation:

f(x) = (x-4)/3

h(x) = 3x + 4

f(h(-1)) = ?

So first off we need to solve for h(-1):

h(x) = 3x + 4

h(-1) = 3(-1) + 4

h(-1) = 1

Next, we plug this value into the f(x) equation:

f(x) = (x-4)/3

f(1) = (1-4)/3

f(1) = -1

f(h(-1)) may look confusing but it is just f(x) with x being the resulting value for h(-1)

Thus we can say that f(h(-1)) is equal to -1
