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.

Answer:

x = 1.2

Step-by-step explanation:

Essentially, because ABCDE and JKLMN are similar, their corresponding sides have a common ratio. To find x, we can simply the ratio between NJ and its corresponding side equal to the ratio of another pair of corresponding sides.

[tex]\frac{BA}{KJ}=\frac{AE}{JN}[/tex]

[tex]\frac{3}{1.8}=\frac{2}{x}[/tex]

3x = 3.6

x = 1.2

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

While on a plane, Charlie counted the number of adults, children, and empty seats. 1/5 of the seats were occupied by children.
3/4 of the seats were occupied by adults.
10 seats were empty .

A. How many passenger seats were on the plane
B. Write how you figured it out

Answers

Answer:

200 seats

Step-by-step explanation:

Let s = numbers of seats

1/5s = children

3/4 s = adults

10 = empty

The total number of seats = children + adults + empty

s = 1/5s + 3/4s + 10

Subtract 1/5s and 3/4s from each side

s -1/5s -3/4s= 1/5s-1/5s + 3/4s-3/4s + 10

s - 1/5s - 3/4s = 10

Get a common denominator

20s/20 - 4s/20 -15s/20 = 10

Combine like terms

1s/20 = 10

Multiply each side by 20

s/20 *20 = 20*10

s = 200

Answer:

19 seats

Step-by-step explanation:

you take the denominators: 5,4, and 9

then you add them to get 19.

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

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
