Answer:

The confidence interval is (24116.3878,24883.6122).

Step-by-step explanation:

We are given the following information in the question:

Population mean, $\mu$ = $23,500

Sample mean, $\bar{x}$ = $24,500

Sample standard deviation,s = $2,800

Sample size, n = 146

Confidence interval:

$\bar{x} \pm t_{critical}\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at}~\alpha_{0.05} = \pm 1.655436$

$24500 \pm 1.65543(\frac{2800}{\sqrt{146}} ) = 24500 \pm 383.6122 = (24116.3878,24883.6122)$

The confidence interval is (24116.3878,24883.6122).

Please help me with this one!!

Tema [17]

Answer:

$21 in^{2}$

Step-by-step explanation:

The square in the middle has a length and width of 3, so multiply. 9.

All of the triangles have a base of 3 and a height of 2. The area equation for triangles is

$A=bh\frac{1}{2}$

So base*height is 6. Divide that by 2 or multiply by 1/2.

You get 3. There are 4 triangles, so multiply that by 4. 12.

Add 12 and 9 together, and you get:

$21 in^{2}$

I hope this helps!

tia_tia [17]

I believe the wording of the question is: If one tray can hold 12 loaves of bread and the rack can hold 10 trays, can a hundred and twenty-five loaves fit on one rack?
Then the answer would be, no.
12 x 10 = 120

How do you solve this absolute value equatuon? 4|x - 1| - 7 = -3

MatroZZZ [7]

4|x - 1| - 7 = -3 |add 7 to both sides

4|x - 1| = 4 |divide both sides by 4

|x - 1| = 1 ⇔ x - 1 = 1 or x - 1 = -1 |add 1 to both sides

x = 2 or x = 0

Answer: B.
