Please help me on this question.

Katyanochek1 [597]

answer:

A) The angles EA and AG are not congruent.

B) m∠F = 90°

m∠E + m∠F = 180°

90 ° + x = 180° (subtract)

x = 90°

C) Both ∠HEF and ∠AGF are congruent becuase they both have the same angle. Try and measure it using a protractor.

graph the function n(x) = (x-1)^2 -7. compare the graph to the graph of f(x) = x^2. i have the vertex which is (-1,-7) how do I

bogdanovich [222]

Answer:

See below.

Step-by-step explanation:

To find the other two points such as the x-intercepts, set the equation equal to 0 and solve for x.

$0 = (x-1)^2 -7\\\\7 = (x-1)^2\\\\\sqrt{7} = \sqrt{(x-1)^2} \\\\+/-\sqrt{7} = (x-1)\\1+/-\sqrt{7} = x$

This means the points will be at (3.64, 0) and (-1.64, 0).

This graph is shifted 1 unit to the right and 7 units down from x^2.

true or false If x represents a random variable with mean 114 and standard deviation 40, then the standard deviation of the samp

Goshia [24]

Answer:

$\mu = 114, \sigma = 40$

We also know that we select a sample size of n =100 and on this case since the sample size is higher than 30 we can apply the central limit theorem and the distribution for the sample mean would be given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

And the standard deviation for the sampling distribution would be:

$\sigma_{\bar X}= \frac{40}{\sqrt{100}}= 4$

So then the answer is TRUE

Step-by-step explanation:

Let X the random variable of interest and we know that the true mean and deviation for this case are given by:

$\mu = 114, \sigma = 40$

We also know that we select a sample size of n =100 and on this case since the sample size is higher than 30 we can apply the central limit theorem and the distribution for the sample mean would be given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

And the standard deviation for the sampling distribution would be:

$\sigma_{\bar X}= \frac{40}{\sqrt{100}}= 4$

So then the answer is TRUE
