Answer:

378 cm^3

Step-by-step explanation:

V = Bh = l * w * h

since the Base B is 54 (l*w), multiply by 7 to find volume

54 * 7 = 378

Driving on the highway, you can safely drive 60 miles per hour. "How far can you drive in ‘h' hours?" What is the range of the f

JulijaS [17]

Answer:

D.The distance you drive

Step-by-step explanation:

If you describe this situation as function, then it will look as:

f(h)= 60h
For h=1 you have f(1)= 60 miles
For h=2 you have f(2)= 120 miles etc.

The range of the function is the set of output values

In this case the range is the distance you drive

Correct option is D.

Suppose your boss wants you to obtain a sample to estimate a population mean. Based on previous analyses, you estimate that 49 i

VashaNatasha [74]

Answer:

the minimum sample size n = 11.03

Step-by-step explanation:

Given that:

approximate value of the population standard deviation $\sigma$ = 49

level of significance ∝ = 0.01

population mean = 38

the minimum sample size n = ?

The minimum sample size required can be determined by calculating the margin of error which can be re[resented by the equation ;

Margin of error = $Z_{ \alpha /2}} \times \dfrac{\sigma}{\sqrt{n}}$

$38 = \dfrac{2.576 \times 49}{\sqrt{n}}$

$\sqrt{n} = \dfrac{2.576 \times 49}{38}$

$\sqrt{n} = \dfrac{126.224}{38}$

$\sqrt{n} = 3.321684211$

$n= (3.321684211)^2$

n ≅ 11.03

Thus; the minimum sample size n = 11.03
