The American Community Survey (ACS), part of the United States Census Bureau, conducts a yearly census similar to the one taken

wariber [46]

Answer:

The point estimate used was of $69,821.

The error bound is of $101.

Step-by-step explanation:

A confidence interval has two bounds, a lower bound and an upper bound.

A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.

The error bound is half the difference between these two values.

In this question:

90% confidence that the mean household income in the U.S. falls between $69,720 and $69,922.

Point estimate:

(69720+69922)/2 = 69821

The point estimate used was of $69,821.

Error bound:

(69922 - 69720)/2 = 101

The error bound is of $101.

Pete took a sample of moviegoers to see how many are seeing a comedy. Sample size: 175 Number seeing a comedy: 42 Population: 1,

Anastaziya [24]

Answer: Part A : c = n.p

Part B = 366 moviegoers

Step-by-step explanation: In part A, to predict the number of moviegoers, we have to find the proportion of the sample that does the activity, which will called p. Since p is a percentage, to determine how many moviegoers are seeing a comedy, you multiply it by the sample size, n.

Therefore: c = n.p

For part B, based on the the sample:

p = $\frac{42}{175}$ = 0.24

The total population is given: 1,525

c = 0.24.1,525

c = 366

Based on the sample, 366 people are seeing a comedy.

The area of a rectangle is 4y + 10.

galben [10]

By definition, the area of a rectangle is given by:
$A = (w) * (l)
$
Where,
w: width
l: long
We then have the following area:
$A = 4y + 10
$
Factoring the area we have:
$A = 2 (2y + 5)
$
Therefore, according to the definition, two possible dimensions of the rectangle are:
$w = 2

l = 2y + 5$
Answer:
The area of the rectangle in factored form is:
$A = 2 (2y + 5)
$
One possible set of dimensions for this rectangle is:
$w = 2

l = 2y + 5$
