What is the area of this figure?

Enter your answer in the box.

Answers

The answer is 28 I think

Answer:

400 sq. in.

Step-by-step explanation:

the parallelogram in the figure has an area of 320 sq. in.

and the right triangle at the top right has an area of 80 sq. in.

adding both areas would equal to 400 sq. in.

( if you're wondering,what about the right triangle at the bottom left?Well that triangle actually gives us the height of the parallelogram which is 16.therefore the triangle's area is already found in the area of the parallelogram.As you should know the area to a parallelogram is A=bh ,and the base is 20 so multiplying 16 x 20 that equals 320.Therefore the triangle's area is already found in the area of the parallelogram.)

4x=3y-2 in slope intercept form
explain

Answers

Answer:

y = 4 /3 x  +  2 /3

Answer:

y = -4/3x - 2/3

Step-by-step explanation:

The slope intecept form is y = (slope)x - (some #).

So, turning 4x = 3y - 2 into the slope intercept form, we get:

4x = 3y - 2

3y = -4x - 2

y = -4/3x - 2/3

The table shows the weights of a sample of packages carried by an air freight company last month. Find the mean deviation for the data in the quantity column.
Select one:

8.09

1.52

2.84

6.18

Answers

Answer:

1.52

Step-by-step explanation:

[tex]\frac{5 + 9 + 5 + 6 + 8 }{5} = \frac{33}{5} = 6.6[/tex]

distance from 6.6

5,  1.6

9,  2.4

5,  1.6

6,   .6

8,  1.4

[tex]\frac{1.6 + 2.4 + 1.6 + .6 + 1.4}{5} = \frac{7.6}{5} = 1.52[/tex]

The mean deviation of the data set is 1.52. The correct option is B.

What is mean?

Mean is defined as the ratio of the sum of the number of data sets to the total number of data.

First, calculate the mean of the data set and then the deviation of each data set.

The mean is calculated as,

Mean =(5+9+5+6+8)/5

Mean = (33/5)

Mean = 6.6

The deviation is,

5      1.6

9      2.4

5      1.6

6      0.6

8      1.4

The mean deviation is calculated as,

Mean = ( 1.6 + 2.4 + 7.6 + 0.6 + 1.4 ) / 5

Mean = 7.6 / 5

Mean = 1.52

Therefore, the mean deviation of the data set is 1.52. The correct option is B.

Step-by-step explanation:

The amount of money Alex would receive at the end of 41/2 years is ₹15,510.

The amount of money Alex would receive at the end of 41/2 years is the sum of the interest he would earn and the amount of money he deposited.

Interest = principal x time x interest rate

12,000 x 4.5 x 0.065 = 3510

The amount of money Alex would receive = 3510 + 12,000 = 15,510

1.Cesiah has a pencil box containing 4 green pencils, 6 blue pencils, and 10 red pencils. If she randomly selects a pencil from the bag, what is the probability, in decimal form, that she picks a green pencil?

Answers

Answer:

If you add up the amount of pencils there are then you get 20,

so that means that you have 20 pencils in all, and out of the 20 pencils, 4 of them are green so the probability is 4/20

and 4/20 in decimal form is 0.2, so the probability is unlikely that she will pick a green pencil
