Answer:

MAD stands for mean absolute deviation so 79.4 is the mean. The MAD should be zero 0

Step-by-step explanation:

We find MAD by "Taking each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. Finally, round to the nearest tenth."-Ixl

So your Mean Absolute Deviation should be 0 zero.

The points have been plotted on the coordinate graph.

Answer:

plot each coordinate pair onto the graph then solve for the function

Step-by-step explanation:

step one: plot each coordinate pain onto the coordinate graph

step two: fuse the vertical line test. Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function

their bases are the same lengths, how do their heights compare? Justify
your answer.

Answers

Answer:

El área de un triángulo es base x altura entre 2

El área de un rectángulo es base x altura

Entonces si tienen misma área y base, realizamos la ecuación;

--> (b x h)/2 = b x H --> Las alturas son diferentes, pero sus áreas son iguales

Simplificamos b

--> h/2 = H

Y sacamos la relación

--> h/H = 1/2

2/3 a - 1/6 = 1/3

answer this math question asap pls

Answers

Answer:

a=3/4

Step-by-step explanation:

1. Get 2/3a by itself.

•Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.

•Because you only add and subtract like denominators

This will make it look like:

2/3a - 1/6 = 2/6

Then, add 1/6 to both sides to get 2/3a by itself.

It'll look like this:

2/3a = 3/6

2. Get a by itself.

•Multiply the reciprocal (opposite) of 2/3 to get a alone.

This will look like:

(3/2) • 2/3a = (3/2) • 3/6

a = 18/24

3. Simplify.

Find the largest number that can simplify the equation.

For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.

But the largest number you can divide both sides by is 6.

18 ÷ 6 = 3 and 24 ÷ 6 = 4.

3/4.

the answer is a= 3/4
