Answer:

R^{2}=0.7744

Step-by-step explanation:

r represents the correlation coefficient between two sets of data. It is a measure of the degree of association between the two sets of data and gives insight into the strength and direction of the relationship.

On the other hand, R^{2} is the coefficient of determination for a given data set. It is a measure of the predictive power of a linear model.

Given r, R^{2} is simply the square of r;

in this case we are given, r = 0.88. Therefore, R^{2}=0.88^{2}\\\\R^{2}=0.7744

How to graph an exponential function
irina1246 [14]

Step-by-step explanation:

Exponential function is given by general form y=ab^x

Where a and b are constants.

say a=1 and b=2 then we can write function as :

y=1*2^x

or y=2^x

To graph this or any exponential function, we just need to find some points then join them by a curved line.

Like plug x=0, 1, 2,... into above function and find points:

plug x=1

y=2^x=2^1=2

Hence point is (1,2)

Find more points similarly then graph them to get the graph as shown below:

Answer:

<6 = 50 percent

Step-by-step explanation:

<2 = <5 = <7 = <9 = 130 percent

<1 + <2 = <6 + <7 = 180 percent

180 percent - <7

180 percent - 130 percent = 50 percent

<6 = 50 percent

A triangle has three angles that measure 15 degrees, 85 degrees and (4x - 20). What is the value of x?
Lostsunrise [7]
180=15+85+(4x-20)
180-15-85=4x-20
80=4x-20
4x-20=80
4x=80+20
4x=100
x=100/4
x=25
