Answer:

a. 587

b. 543

Step-by-step explanation:

a. Mean = sum / number of numbers

To find the sum, we can add the numbers up.

432 + 543 + 348 + 788 + 823 = 2934

There are 5 numbers. Our mean is thus

2934/5 = 586.8, or 587 when rounding up. We round up because we have a .8 at the end, and 8 ≥ 5

b. To find the median, we first must order the numbers. The numbers ordered are this:

348 , 432 , 543 , 788 , 823

To find the median, we can cross off one number on each side until we are left with one or two numbers.

348 , 432 , 543 , 788 , 823

cross out one number from each endpoint

432 , 543 , 788

cross out one number from each endpoint

543

Solve the system by substitution. 3x + y = 20 -7y=x Please help

alisha [4.7K]

Answer:

(x, y) = (7, -1)

Step-by-step explanation:

The expression for x makes it easy to use that for substitution.

3(-7y) +y = 20

-20y = 20 . . . . . collect terms

y = -1 . . . . . . . . . divide by -20

-7(-1) = x = 7 . . . use y in the second equation to find x

The solution is (x, y) = (7, -1).

Find the area of the figure. Use 3.14 for π.

siniylev [52]

Answer:

Area of the figure= $51.5feet^2$

Step-by-step explanation:

Area of the figure=Area of the middle rectangle+ Area the the two triangles

Area of the rectangle=Length*Width

$Length= 8+3 =11 feet\\\\Width=4 feet$

$Area = 11*4\\\\ =44 feet^2$

Area of the triangle with the height of 2 feet and base= 3 feet

Area= $\frac{1}{2} *Base*Height$

= $=\frac{1}{2} *3*2\\\\=\frac{1}{2}*6\\\\ =3 feet^2$

Area of the triangle with the Height=3 feet and Base= 3 feet

Area= $\frac{1}{2} *Base*Height$

$=\frac{1}{2}*3*3\\\\ =\frac{1}{2}*9\\\\ =4.5feet^2$

Total Area of the figure $=44+3+4.5=51.5 feet^2$
