What is the midpoint of the class 15-20

Answers

Answer 1
More data can be applied to the frequency distribution table. You can measure the "midpoint" (or "class mark") of each class as: Midpoint = Lower class limit + Upper class limit 2 . . The proportion of the data that falls in that class is the "relative frequency" of each class.

Answer:

Part A:  y = 4.5x + 22

Part B:  31 inches

Step-by-step explanation:

Part A:

the y-intercept appear to be at 22

the slope can be found by using the points (0, 22) and (4, 39)

m = 39 - 22

        4 - 0

m = 17 / 4 = 4.3 and this is close to 4.5

Part B:

plug in 2 for 'x' in the equation: y = 4.5x + 22

y = 4.5(2) + 22

y = 9 + 22

y = 31

Answers

Step-by-step explanation:

The semicircle that was removed has the exact same area as the newly added semicircle.

Hence,

Area of Figure

= Area of Rectangle = (16)(8) = 128.

Answer:

In the figure a semicircle is added to the rectangle and same semicircle is removed

So, Area will be the same as the required rectangle

=(16)(8)=128 square unit

128 square unit is the right answer.

k/3 + 4=10

Answers

K/3 + 4 = 10
K/3 = 10 - 4
K/3 = 6
K = 6x3
K = 18

Answer:

k=18

Step-by-step explanation:

k/3+4=10

subtract 4 from both sides.

k/3+(4-4)=10-4

k/3=6

multiply 3 on both sides.

k/(3/3)=6*3

k=18

Check using substitution method.

(18)/3+4=10

Use order of operations to solve. (PEMDAS)

6+4=10

If ON = 9x - 8, LM = 8x + 4, NM = x - 8, and OL = 3y - 5, find the values of x and y for which LMNO must be a parallelogram.​

Answers

Answer:

x is 12 and y is 3

Step-by-step explanation:

Given a parallelogram LMNO,

LM = ON and OL = NM

Given;

ON = 9x - 8

LM = 8x + 4

NM = x - 8, and

OL = 3y - 5

Substitute into the expression

LM = ON

8x + 4 = 9x - 8

8x - 9x  = -8 - 4

-x  = -12

x = 12

Also OL = NM

3y - 5 = x - 8

3y - 5 = 12-8

3y - 5 = 4

3y = 4+5

3y = 9

y = 9/3

y = 3

Hence the value of x is 12 and y is 3

Answers

Hm do any of those even match up

Answer:

Step-by-step explanation:

None of them.

Any point on y = -2 has a notation of (x,-2). Every x value has a y value of - 2.

None of the given points do. Therefore none of the points are on the line y = - 2

Calculate the area of the regular pentagon below:
A regular pentagon with side length of 11.8 inches and dotted line from center to middle of side of 8.1 inches.

Answers

Answer: 238.95 in²

because this is a regular pentagon

=> the area of the regular pentagon will be 5 times the area of the triangle in the picture.

we have: the area of the triangle is: (11,8.8,1)/2 = 47,79 (in²)

=> the area of the regular pentagon is 5. 47,79 = 238,95 (in²)
