A large home improvement store wants to decide if it should expand the selection of moving products like cardboard boxes and packing tape. The store wanted to construct a 95% confidence interval to estimate the proportion of people who have moved houses at least once in the last 5 years. In its sample of 620 customers, 201 replied that they had moved at least once in the last 5 years. Which of the following is a true statement regarding the value of the point estimate and standard error of the percentage of customers who have moved in the last 5 years?

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

its an acute right triangle

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
