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

2.8 = (12*9.8 - 8/3 V²) ÷ 12 find V

Korvikt [17]

Answer:5.6

Step-by-step explanation:2.8×12=12×9.8-8/3v^2

33.6=117.6-8/3v^2

8/3v^2=117.6-33.6

8/3v^2=84

8v^2=84×3

8v^2=252

V^2=31.5

V=√31.5

V=5.6125

V~5.6

Select the correct answer.

Svetlanka [38]

Answer:

<h3> $\boxed{ \boxed{ \bold{ {x}^{2} + 4x - 21}}}$ </h3>

Step-by-step explanation:

$\sf{(x - 3)(x + 7)}$

Use the distributive property to multiply each term of the first binomial by each term of the second binomial.

⇒ $\sf{x(x + 7) - 3(x + 7)}$

⇒ $\sf{ {x}^{2} + 7x - 3x - 21}$

Collect like terms

⇒ $\sf{ {x}^{2} + 4x - 21}$

Hope I helped!
