The integers are 56,84 and 49.

Step-by-step explanation:

Let the first integer to be x

Let the third integer to be y

The first integer is 28 less than the second integer, this mean the second integer is x+28

The sum of the three integer is 189,this means

x+x+28+y=189

2x+y=189-28

2x+y=161--------------------------------------(1)

The second integer is 21 less than the sum of the first and third integer, this means;

x+28+21=x+y

x+49=x+y

x-x+49=y

49=y-----------------------------------------value of 3rd integer

Substitute value of y=49 in equation (1)

2x+y=161

2x+49=161

2x=161-49

2x=112

x=112/2 =56

x=56-----------------------------------value of 1st integer

Substitute x=56, in the expression for the value of 2nd integer

Second Integer=x+28 = 56 +28 =84

<u>Conclusion</u>

1st integer is 56

2nd integer is 84

3rd integer is 49

you deposit 200 into an account that pays 7% interest compounded quarterly. how much will you have in 5 years
scoray [572]
First, convert R percent to r a decimal
r = R/100
r = 7%/100
r = 0.07 per year,

Then, solve our equation for A
A = P(1 + r/n)nt
A = 200.00(1 + 0.005833333/12)(12)(5)
A = $ 283.53

Summary:
The total amount accrued, principal plus interest,
from compound interest on an original principal of
$ 200.00 at a rate of 7% per year
compounded 12 times per year
over 5 years is $ 283.53.

Which best represents the center of the data set below?
MA_775_DIABLO [31]

Answer: mean = 318.3

Median =330

Mode= 200

Step-by-step explanation:

Mean (average) is the total sum of values in a given a data set ÷ number of values

= 3820/12

Mean= 318.3

Median= midpoint value in a given data set. When the data set is an even number, median is calculated with the 2 middle point values as n1 + n2/2

Step 1: we rearranged the data set from least to highest value to give

200,200,220, 240,300,320,340,360,380,400,420 and 440

Median= 320 + 340/2

=660/2 = 340

Mode is the value with highest frequency in a given data set, from the given question, mode = 200
