Answer:

Step-by-step explanation:

To find 12.5% of 2 dozen

We convert 2 dozen into a number which would be:

2×1 dozen (1 dozen = 12)

2×12=24

12.5% of 24 will be

10% of 24 will be 24÷10=2.4

2.5% will be 1/4 of 10%

Karolina [17]

Answer:

Standard error = 5.4

Step-by-step explanation:

We are given that Population Mean, $\mu$ = 150 and Population Standard deviation, $\sigma$ = 27 and sample size, n = 25

Standard error formula for the sampling distribution of this sample mean is given by;

Standard error = $\frac{\sigma}{\sqrt{n} }$ = $\frac{27}{\sqrt{25} }$ = 5.4

What is the solution of 3 sqrt x+8=-4?

ryzh [129]

Answer:

$x=-72$

Step-by-step explanation:

The given equation is $\sqrt[3]{x+8}=-4$ .

We cube both sides of this equation to obtain;

$(\sqrt[3]{x+8})^3=(-4)^3$ .

This implies that;

$(x+8)=-64$

We group similar terms to obtain;

$x=-64-8$

We simplify the right hand side of the equation to obtain;

$x=-72$

Therefore x=-72 is the solution of the given equation.
