Split this up into the four years.

For the first year, multiply 200 x .02 to get 4
Add 4 onto your total. ($204.00)

For the second year multiply 204 x .02 to get 4.08
Add 4.08 onto your total. ($208.08)

For the third year multiply 208.08 x .02 to get 4.1616 but round to 4.16
Add 4.16 onto your total ($212.24)

For the fourth year multiply 212.24 x .02 to get 4.2448 but round to 4.24
Add 4.24 onto your total (216.48)

Now subtract 200 from your total

216.48-200 = 16.48

She will be payed $16.48 in interest.

Find the midpoint of the segment with the following endpoints.<br> (4,2) and (7,6)
Tema [17]

Answer:

The answer is

<h2>( \frac{11}{2} \: , \: 4)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(4,2) and (7,6)

The midpoint is

M = ( \frac{4 + 7}{2}   \: , \:  \frac{2 + 6}{2} ) \\  = ( \frac{11}{2} \: , \:  \frac{8}{2} )

We have the final answer as

( \frac{11}{2} \: , \: 4)

Hope this helps you

What is the multiplicative inverse of −3/5?
bonufazy [111]

Answer:

The multiplicative inverse is -5/3

Step-by-step explanation:

Multiplicative inverse means we want to end up with 1

-3/5 * what =1

Multiply by 5 to clear the fraction

-3/5 * what *5 = 1*5

-3 * what = 5

Divide by -3 to isolate what

-3*what /-3 = 5/-3

what = -5/3

The multiplicative inverse is -5/3

To make a sports drink for the football team, Jaylen filled 9/10 of a large cooler with water. Then, he filled the remaining spa
avanturin [10]
He made 3.75 gallons. There was 1/10 remaining, meaning each tenth was 6 cups. The entire thing is 10 tenths so you do 6(10) to get 60 cups. After converting to gallons by doing 60÷26, you get 3.75.

Suppose that in a certain county 37% of voters are registered as Democrats, 29% as Republicans, 7% as Green party, and the rest
Fantom [35]

Answer:

0.66

Step-by-step explanation:

GIVEN: Suppose that in a certain county 37\% of voters are registered as Democrats, 29\% as Republicans, 7\% as Green party, and the rest are considered Independents. You conduct a poll by calling registered voters in the county at random.

TO FIND: Probability that the first call will be to either a Democrat or a Republican.

SOLUTION:

Lets total population of county be 100x.

voters registered as Democrats =37\%=\frac{37}{100}\times100x

                                                     =37x

voters registered as Republicans =29\%=\frac{29}{100}\times100x

                                                       =29x

voters registered as Green party =7\%=\frac{7}{100}\times100x

                                                       =7x

Probability that first call will be to Democrats P(A)=\frac{\text{total democrats}}{\text{total voters}}

                                                                                    =\frac{37x}{100x}=0.37

Probability that first call will be to Republican P(B)=\frac{\text{total republicans}}{\text{total voters}}

                                                                                     =\frac{29x}{100x}=0.29

probability that the first call will be to either a Democrat or a Republican

=P(A)+P(B)

=0.37+0.29

=0.66

Hence the probability that the first call will be to either a Democrat or a Republican is 0.66
