20% of 120 is 24.

To find this answer, you need to use the percentage formula (is over of equals the percentage over 100, is/of = p/100).

Plug in the known numbers. You know you need 20%, so plug 20 into the percentage place.

is/of = 20/100

You know the "of," which is 120, so plug that in.

is/120 = 20/100

You don't know the "is," so to find it you need to multiply cross multiply 120 by 20. Then you need to divide your answer by 100 to find your missing value (is).

120 * 20 = 2,400
2,400 / 100 = 24

Answer:

VX = 8.8 in

Step-by-step explanation:

By applying Sine rule in the right triangle WXV,

Sin(∠W) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

= $\frac{\text{VX}}{\text{WX}}$

Sin(34)° = $\frac{VX}{15}$

VX = 15.Sin(34)°

= 8.8379

≈ 8.8 in.

Therefore, measure of side VX is 8.8 in.

What is 6.213 as a mixed number

Ira Lisetskai [31]

6.213 as a mixed number would be 6 and 213/1000.

all you do to convert it to a mixed number is look at how many numbers are after the decimal.

since theres 3 numbers, that means it would be in the thousands place

Suppose that salaries for recent graduates of one university have a mean of $25,700 with a standard deviation of $1350. Using Ch

sergeinik [125]

Answer:

75% of the data will reside in the range 23000 to 28400.

Step-by-step explanation :

To find the range of values :

We need to find the values that deviate from the mean. Since we want at least 75% of the data to reside between the range therefore we have,

$1 - \frac{1}{k^2} =\frac{75}{100}$

Solving this, we would get k = 2 which shows the value one needs to find lies outside the range.

Range is given by : mean +/- (z score) × (value of a standard deviation)

⇒ Range : 25700 +/- 2 × 1350

⇒ Range : (25700 - 2700) to (25700 + 2700)

Hence, 75% of the data will reside in the range 23000 to 28400.
