Answer:

The correct set of hypotheses is

H_{0}: d=80 degrees

H_{0}: d>80 degrees

Step-by-step explanation:

The weatherman claims that the average temperature during July in Chattanooga is 80 degrees or less. To test this claim, following hypotheses need to be taken:

Let d be the the average temperature during July in Chattanooga, then

H_{0}: d=80 degrees

H_{0}: d>80 degrees

It is possible to rent 8 ping pong tables.

This is because if you are renting a bowling lane for 2 hours you would do 12+12 and that’s 24. You would then do 24/3 cause that’s the amount of the cost for 1 hour of the ping pong to rent and that would give you and answer of 8.
Hope that’s helps:)

What is an equation of the line that passes through the points (-6,2) and <br> (-6, 6)?

Answer:

Step-by-step explanation:

y

=

−

2

3

x

+

2

Explanation:

Given that we have the slope and a point on the graph we can use the point slope formula to find the equation of the line.

Point-Slope Formula:

y

−

y

1

=

m

(

x

−

x

1

)

, where

m

is the slope of the line and

x

1

and

y

1

are x and y coordinates of a given point.

We can summarize the information already given:

m

=

−

2

3

x

1

=

6

y

1

=

−

2

Using this information, we can substitute these values onto the point-slope formula:

y

−

2

)

=

(

x

−

(

6

)

)

y

+

2

=

−

3

(

x

−

)

The equation above is the equation of the line in point-slope form. If we wanted to have the equation in

y

=

m

x

+

b

form then we simply solve the equation above for
