You are given n = 5 measurements: 5, 3, 3, 8, 8. (a) calculate the sample mean, x. (enter your answer to one decimal place.)

mojhsa [17]

The mean = sum of all the measurements / number of measurements (n)

= (5 + 3 + 3 + 8 + 8) / 5

= 27 / 5

= 5.4 Answer

Lauren's age can be represented by the expression 10m2. Kristen's age can be represented by the expression 2m5.

madreJ [45]

To solve this we need to write down ratio and try to simplify it.

10m^2/2m^5 is the ratio
We can divide both numbers by 2m^2
Once we do that we are left with
5/m^3

Looking at the answers we find that correct answer is A

Solve the equation. 5x 8 − 3x = −10 x = −9 x = −1 x = 1 x = 9

gregori [183]

The value of the variable <em>x, </em>of the linear equation 5x 8 − 3x = −10 is -9, which is obtained after solving it. Option 1 is the correct option.

<h3>What is linear equation?</h3>

A linear equation is the equation in which the highest power of the unknown variable is one.

Here, the given linear equation is,

$5x +8 - 3x = -10$

Solve it by arranging the equation as,

$5x - 3x +8= -10\\2x+8=-10$

Subtract number 8 both side of the equation as,

$2x+8-8=-10-8\\2x=-18$

Divide both side of the equation with number 2 as,

$x=\dfrac{-18}{2}\\x=-9$

Hence, the value of the variable <em>x, </em>of the linear equation 5x 8 − 3x = −10 is -9, which is obtained after solving it. Option 1 is the correct option.
