To solve for the solution of this system of equations,there are many ways to go about doing it, finding the point where the lines both intersect at.

One of the easiest is substitution, so plug in either one of the equations for the other one.

Y = X+4
Y = -4 + X
X+4 = -4 + X

Then solve for the X value to obtain the X coordinate of the point.

X+4 = -4 + X
X - X + 4 + 4 = -4 + 4 + X - X
8 = 0.
Since after trying to solve for X, we couldn't solve for it, and instead gave us numbers that are not equal to each other, there is no solution to these systems of equations, in other words, they don't intersect at a particular point.

The table below shows the height (in inches) and weight (in pounds)of eight basketball players.
Height=67, 69, 70, 72, 74, 78, 79 Weight=183, 201, 206, 240, 253, 255 what is the correlation of the set of data? Round your answer to the nearest thousandth.

d.0.981

3.The table below shows the average height of a species of tree (in feet) after a certain number of years.
Years=1, 2, 3, 4, 5, 6, 7, 8 Height=2.1, 3.2, 6.8, 7.3, 11.2, 12.6, 13.4, 15.9 about how tall would you expect one of these trees to be after 22 years?

c.44.25ft 


4.You use a line of best fit for a set of data to make a prediction about an unknown value. The correlation coefficient for your data set is 0.984. How confident can you be that your predicted value will be reasonably close to the actual value?

c.I can be very confident; it will be close, but it probably won't be exact.

Sonya took out a mortgage of $65,000 at 7% for 25 years. What is the cost of the mortgage?
Vika [28.1K]

The cost of the mortgage is $81250

<h3>What are interests?</h3>


Interests are percentages of a principal

Given the following parameters

Principal = $65000

Rate = 7% = 0.07
Time = 5 years

<h3>Calculate the interest</h3>

I = PRT/100
I = 65000*0.07*25
I = 16,250

<h3>Determine the cost of the mortgage</h3>

Cost of mortgage = Principal + Interest

Cost of mortgage = 65000 + 16250
Cost of mortgage = 81,250

Hence the cost of the mortgage is $81250
