Mathematics
1 answer:
polet [3.4K]3 years ago
6 0

Answer:

B  x=3

Step-by-step explanation:

12x = 2x^2 +18

Divide by 2

12x/2 = 2x^2/2 +18/2

6x = x^2 +9

Subtract 6x from each side

6x-6x = x^2 -6x+9

0= x^2 -6x+9

Factor

What 2 numbers multiply to 9 and adds to -6

-3*-3 = 0

-3+-3 =-6

0= (x-3) (x-3)

Using the zero product  property

x-3 =0   x-3 =0

x=3   x=3

The statue of liberty is 305 feet tall from the base to the torch. The statue itself is 111 feet tall. How many feet tall is the
mr Goodwill [35]
Base height + statue height = total height

Total height = 305
statue height = 111

base height + 111 = 305
Subtract both sides by 111
base height = 194

The height of the base is 194 feet.

Have an awesome day! :)

The frequency distribution representing the number of frequent flier miles accumulated by employees at Brumley Statistical Consu
alisha [4.7K]

Answer:

a. How many employees accumulated less than 3,000 miles?

The number of employees accumulated less than 3,000 miles= 5

So the number of employees accumulated less than 3,000 miles is 5.

d. Based on the cumulative frequency polygon, about 75% of the employees accumulated how many miles or less?

8.5 thousands of miles, found by starting at 75 percent on the vertical axis on the right, over to the polygon and then down to the horizontal axis.

Step-by-step explanation:

The given frequency distribution representing the number of frequent flier miles accumulated by the employees in a company.                        

Frequent Flier Miles (000) Frequency

0                     up to 3 5

3                      up to 6 12

6                      up to 9 23

9                     up to 12 8

12                   up to 15 2

Total                       50

a. How many employees accumulated less than 3,000 miles?

The number of employees accumulated less than 3,000 miles= 5

So the number of employees accumulated less than 3,000 miles is 5.

b. Convert the frequency distribution to a cumulative frequency distribution.

We make the cumulative frequency distribution from the frequency distribution by adding up a frequency and all other frequencies below it.                

Frequent Flier Miles Frequency Cumulative frequency

0 up to 3                                5 5

3 up to 6                                      12 17

6 up to 9                                      23 40

9 up to 12                               8 48

12 up to 15                               2 50

Total 50

d. Based on the cumulative frequency polygon, about 75% of the employees accumulated how many miles or less?

8.5 thousands of miles, found by starting at 75 percent on the vertical axis on the right, over to the polygon and then down to the horizontal axis.
