Multiply the two numbers to get the answer:

4 1/2 X 2-2/5 = 10-4/5 or 10.8

The correct answer is 8.3 repeated.

25 divided by 3 is 8.3 repeated and so is the rest so it is obvious to say that 8.3 repeated is the correct answer.

A consumer electronics company is comparing the brightness of two different types of picture tubes for use in its television set

Answer:

The answer is "0.7794".

Step-by-step explanation:

Please find the complete question in the attached file.

Given:

$\to n_{1}=n_{2}=25\\\\$

Hypotheses:

$\to H_{0}:\mu_{B}-\mu_{A}\geq 0\\\\\to H_{a}:\mu_{B}-\mu_{A}< 0\\\\$

Testing statistics:

$\to z=\frac{(\bar{x}_{B}-\bar{x}_{A})-(\mu_{B}-\mu_{A})}{\sqrt{\frac{\sigma^{2}_{B}}{n_{1}}+\frac{\sigma^{2}_{A}}{n_{2}}}}=\frac{3.5-(0)}{\sqrt{\frac{16^{2}}{25}+\frac{16^{2}}{25}}}=0.77$

The test is done just so the p-value of a test is

$\to p-value = P(z < 0.77) = 0.7794$

Because the p-value of the management is large, type B can take it.

Answer:

in the step-by-step

Step-by-step explanation:

okay one thing is that you labelled wrong since you have to label D', D", D'" (you just labelled with one for all of them)

a you reflected across the y-axis wrong

-it would be that D' (-2,6), E' (-2,3), F' (-5,3)

b you rotated correctly

this gets more confusing since you labelled the triangles wrong, but I hope this first part helps
