Answer:

f(x)=-2x+10

Step-by-step explanation:

The given line passes through (6-2).

The given is perpendicular to 2y=x-4.

We solve for y in the given equation to get;

y=\frac{1}{2}x-2

The slope of this line is \frac{1}{2}

The slope of the line perpendicular to this line is the negative reciprocal of the \frac{1}{2}.

Hence; m=-\frac{1}{\frac{1}{2} } =-2

The equation is given by

y-y_1=m(x-x_1)

We substitute the point (x_1,y_1)=(6,-2) to obtain;

y--2=-2(x-6)

Hence the required equation is;

y+2=-2x+12

y=-2x+12-2

y=-2x+10

The function notation is

f(x)=-2x+10

Answer:

d. H0: melanoma mortality rate is not linearly related to latitude

   Ha: melanoma mortality rate is linearly related to latitude

Step-by-step explanation:

The linear regression equation is

y=α+βx where α=intercept and β=slope.

β=slope demonstrates the change in dependent variable due to unit change in independent variable.

If the slope is zero then we can say that Y and X are not linearly related.

Thus, the hypothesis for testing significance of linear relationship two variables can be written as

Null hypothesis: The two variables are not linearly related i.e. β=0

Alternative hypothesis : The two variables are linearly related i.e. β≠0.

Thus, in the given scenario the hypothesis are

H0: melanoma mortality rate is not linearly related to latitude

Ha: melanoma mortality rate is linearly related to latitude.

What are the solutions to the equation 3(x – 4)(x + 5) = 0
Ne4ueva [31]

Answer:

x=4

x=-5

Step-by-step explanation:

in order for this to be equal to 0, 1 or both of the factors has to be 0, because anything multiplied by 0 is 0.

123 * 29382 * 8139* 0 = 0

x-4 = 0

x = 4

x+5 = 0

x=-5
