Iteru [2.4K]

Part a
The sample size is large enough to use the central limit theorem because it is greater than 30.

Part b.
The mean of the sampling distribution is 62000.
The standard error is computed as
$SE=\frac{s}{\sqrt{n}}=\frac{27000}{\sqrt{100}}=2700$

Part c.
Compute for the corresponding z-score of more than 2700 from the population mean.
$z=\frac{2700}{2700}=1$

Therefore,
$P\left(z\ \textgreater \ 1\right)=0.1587$

The national weather service reports the daily temperature in degrees

kobusy [5.1K]

Answer:

$C =\frac{5}{9}(F - 32)$

Step-by-step explanation:

Given

$F = 1.8C + 32$

Required

Solve for C

$F = 1.8C + 32$

Subtract 32 from both sides

$F-32 = 1.8C + 32-32$

$F-32 = 1.8C$

Divide both sides by 1.8

$\frac{1}{1.8}(F - 32) = C$

Express the decimal as fraction

$\frac{1}{18/10}(F - 32) = C$

$\frac{10}{18}(F - 32) = C$

Simplify

$\frac{5}{9}(F - 32) = C$

$C =\frac{5}{9}(F - 32)$

On a coordinate plane, 2 right triangles are shown. The first triangle has points A (negative 1, 3), B (negative 1, 1), C (3, 1)

drek231 [11]

Answer:

B and E

Step-by-step explanation:

<u>Given</u>

ΔABC ⇒ A(- 1, 3), B(- 1, 1), C(3, 1)
ΔA'B'C' ⇒ A'(2, - 2), B'(2, - 4), C'(6, - 4)

<u>Comparing the coordinates of the corresponding vertices, we see the difference:</u>

x → x + 3, y → y - 5

It means the ΔABC has been translated 3 units right and 5 units down

Correct answer choices are B and E
