A survey is carried out by the finance department to deter-mine the distribution of household size in a certain city. They draw a simplerandom sample of 1,000 households. Afper several visits, the interviewers findpeople at home in only 653 of the sampfe households. Rather than face such ahigh non-response rate, the department draws a second batch ofhouseholds, and uses the first 347 completed interviews in the second batch to bring thesample up to its planned strength of 1,000 households. The department counts3,087 people in these 1,000 households, and estimates the average householdsize in the city to be about 3.1 persons.

Is this estimate likely to be too low, too high, or about right?

step-by-step explanation:

1699/ 8548

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
