A) 12 x - 18 = 4x + 30

olga55 [171]

Answer:

x = 6

Step-by-step explanation:

You add 18 to both sides so that the equation turns into 12x = 4x + 48

Then you subtract 4x from both sides so that the equation becomes 8x = 48

Then you divide both sides by 8 and get x = 6

Effectus [21]

Answer:

V = 4.187r³

Step-by-step explanation:

Volume of a sphere is expressed using the formula;

V = 4/3πr³

r is the radius

Substitute π = 3.14 into the formula

V = 4/3 * 3.14r³

V = 4.187r³

Hence the volume of a sphere in terms of the radius is V = 4.187r³

A new company opens and finds the profits from their first year in business is $24,000. They project the company's profits to in

Fiesta28 [93]

Answer:

$4406.7 is the profit.

explanation:

compound interest formula: $\sf \large\boxed{\sf P(1+\frac{r}{100})^n }$

using this formula:

$\rightarrow \ \sf \sf 24000(1+\dfrac{1.7}{100})^{10} }$

$\rightarrow \sf \ $ \sf 28406.7$

profit: $28406.7 - $24,000 = $4406.7

From the data given, we estimate the population mean and population standard deviation. Then, we use this estimate to find a 95% confidence interval for the population variance and the population standard deviation.

Sample:

Salaries in millions of dollars: 2.2, 1.5, 0.5, 1.3, 2.4, 1.5, 2.7, 0.3, 2.0, 0.3

Question a:

The mean is the sum of all values divided by the number of values. So

$\overline{x} = \frac{2.2 + 1.5 + 0.5 + 1.3 + 2.4 + 1.5 + 2.7 + 0.3 + 2.0 + 0.3}{10} = 1.42$

The sample mean salary is of 1.42 million.

Question b:

The standard deviation is the square root of the difference squared between each value and the mean, divided by one less than the number of values.

So

$s = \sqrt{\frac{(2.2-1.42)^2 + (1.5-1.42)^2 + (0.5-1.42)^2 + (1.3-1.42)^2 + (2.4-1.42)^2 + (1.5-1.42)^2 + (2.7-1.42)^2 + ...}{9}} = 0.8772$
