Answer:

A. 22

Step-by-step explanation:

Let's use variables to represent the unknowns.

Let x = blue bowl

Let y = orange symbol

Let z = yellow brush

x * x * x = 512

x^3 = 512

x = sqrt^3(512) = 8

xy^2 = 72

8 * y^2 = 72

y^2 = 9

y = 3

yz = 33

z = 11

x + y + z = 8 + 3 + 11 = 22

Write an equation to match each graph:

castortr0y [4]

From what I know this graph looks like that of a modulus function except it's shifted 1 unit to right and 1 unit below the origin.

So the original equation must be:
y = |x|

And the transformed equation (aka the equation if this graph) must be,

y+1 = |x| -1

y = |x| -2

HELP Sam measures the height of 7 different scoops of ice cream. The mean of the heights was 3.8 cm. Which of the following best

OLga [1]

Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm. If all the scoops are evenly distributed, they would all be 3.8 cm tall.

<h3>How to find the mean value of a data set?</h3>

The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.

If the data set consists of values

x_1, x_2, ..., x_n

, then we get the mean value as:

$\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}$
