F(x)= 1+1.5x because he starts at one mile and climbs 1.5 miles every hour after that and x represents hours

Answer:

The answer is f(x) = 1 + 1.5x

Step-by-step explanation:

If Mark started a rock climb when he was 1 mile above sea level, and we're trying to find Mark's height above sea level over time, we would need to add 1 to our function.  And since he climbed 1.5 miles an hour(x) you must add that as well.  So far, we have, 1 + 1.5x.

Therefore, the answer would be f(x) = 1 + 1.5x.

Hope I helped :)

The following correlations were computed as part of a multiple regression analysis that used education, job, and age to predict
erma4kov [3.2K]

Answer:

Job has the weakest association with the dependent variable income.

Step-by-step explanation:

The correlation coefficient is used to determine the the strength and direction of the relationship between two variables.

It is denoted by <em>r</em> and the value of <em>r</em> ranges from -1.00 to 1.00.

The correlation data provided is as follows:

                    Income    Education    Job     Age

Income         1.000      

Education     0.677        1.000

Job                0.173         -0.181        1.000

Age               0.369        0.073        0.689   1.000

The dependent variable is the income.

And the variables Education, Job and Age are independent variables.

The correlation between Income and Job is 0.173.

This is the lowest correlation coefficient between the dependent and independent variable.

Thus, Job has the weakest association with the dependent variable income.

Find angle measures and arc measures
Vlad1618 [11]

Answer:

Step-by-step explanation:

a. We know that KH is a diameter of the circle and that along angles along it on either side adds up to 180° as it's a straight line.

-Therefore, we have that:

m\angle a+ \angle GaH=180\textdegree\\\\\\m\angle a=180-35\\\\=145\textdegree

Hence, the angle a is equal to 180°

b.We know that GJ is a diameter of the circle and that along angles along it on either side adds up to 180° as it's a straight line.

-Therefore, we have that:

m\angle b+\angle GaK=180\textdegree\\\\m\angle b=180\textdegree -145\textdegree\\\\\\\\=35\textdegree

Hence, the angle b is equal to 35°

What's the formula for a triangle if your trying to find the area?
Minchanka [31]

Answer:

A=\frac{1}{2}bh

Step-by-step explanation:

In the formula listed above, "A" represents the area of the triangle, "b" represents the base of the triangle, and "h" is the height/altitude of the triangle.

This makes sense because the area of a square is base*height and a triangle is half of a square.
