Make up a data set of five values with a mean of 10 and a median of 12 None of the values in your data set can be reapeted
Tanya [424]

Answer: See explanation

Step-by-step explanation:

Let the numbers be 2, 6, 12, 13 and 17.

From the given numbers, the mean will be:

= (2+6+12+13+17) / 5

= 50/5

= 10

The mean is 10

The median is 12 as it is the number in the middle when the values given are arranged in either ascending or descending order.

Given f(x) = the quantity of x minus 5, divided by 3, solve for f−1(3).
Fudgin [204]

Remark

Let f(x) = y must to make it easier to write.

Equation

Original Equation: y = (x - 5)/3

Inverse

Interchange the x and y. You get x = (y - 5) / 3

Solve for y in the inverse.

x = (y - 5)/3 Multiply by 3

3x = y - 5 Add 5 to both sides.

3x + 5 = y

<u><em>substitute f1(x) back into the equation.</em></u>

3x + 5 = f(x) Now put in 3 for x

f(3) = 3x + 5

f(3) = 3*3 + 5

f(3) = 14 <<< Answer
