Answer:

HL (Hypotenuse Leg)

Step-by-step explanation:

You have BC=CD (Because of reflexive property), AC=DC, and measure of BAC is equal to the measure of BDC, which is 90 degrees. Since these triangles are right and they have a hypotenuse and a leg congruent, you can say that they are congruent because of HL.

Answer: 0.1

Step-by-step explanation:

Given : A Houston department store sampled 80 items sold in January and found that 8 of the items were returned.

In other words, sample size : n=1040

Number of items returned : x= 8

Let p be the proportion of items returned for the population of sales transactions at the Houston store.

As per sample , the sample proportion of items returned for the population of sales transactions at the Houston store is :

$\hat{p}=\dfrac{x}{n}=\dfrac{8}{80}=0.1$

As we know that , the sample proportion is the best estimate of the population proportion.

Therefore,a point estimate of the proportion of items returned for the population of sales transactions at the Houston store is 0.1.
