if Sonja makes $2100 interest after investing $15,000 at 2.8%, how many years did she invest for?

Answers

Answer:

Sonja invested for 5 years.

Step-by-step explanation:

First you have to find how much money she gets in one year.

To do this you would have to multiply 15,000 and 2.8.

15,000 x 2.8 = 42000

You move the decimal 2 spaces forward since there are 3 zeros in 15,000 and one decimal place in 2.8.

This gives you 420.

To find how many years it takes for her to make $2100 you have to divide

2,100/420.

This gives you 5, which means that she invested for 5 years.

Step-by-step explanation:

Number of diagonals in a 88-gon = 3740

Step-by-step explanation:

Number of diagonals of a polygon

(where 'n' is the number of sides)

[tex] = \frac{n \times (n - 3)}{2} [/tex]

[tex] = \frac{88 \times (88 - 3)}{2} [/tex]

[tex] = \frac{88 \times (85)}{2} [/tex]

[tex] = \frac{7480}{2} [/tex]

[tex] = {3740} [/tex]

A fair coin is flipped 20 times. If the coin lands on
heads 13 times, which statement is true?
A. The coin lands on heads 3 less times than
expected.
B. The coin lands on heads 3 more times than
expected.
C. The coin lands on heads 5 less times than
expected.
D. The coin lands on heads 5 more times than
expected.

Answers

B because it’s a 50% chance of getting heads/tails and it landed 13 times out of 20 on heads so 3 more then 50% of 20
b because the coin has a 50% chance to land on heads or tails. Which means if its flipped 20 times it has a 50% chance to land on heads which is 10 times. The coin landed on heads 13 tikes which is 3 more than 10

explain how to find the slope of a line through two points on a table

Answers

Answer:

you use slope formula m=y2-y1/x2-x1

m=21-11/5-3=15.8

Step-by-step explanation:

so the 3 points you have are (-1,-9) (3,11) (5,21)

so i'm going to choose (3,11) and (5,21) 3 is x1 11 is y1

                                                                5 is x2 11 is y2

m=y2-y1/x2-x1

m=21-11/5-3=15.8
