Mathematics
1 answer:
wlad13 [49]3 years ago
7 0

Answer:

They paid $67.45 altogether.

Step-by-step explanation:

First off, we need to set up the problem, I like to do percentage problems like this:

x/58.65 = 15/100

Cross Multiply

100x=58.65x15

When you multiply 58.65 and 15 you get 879.75

Divide

Now we have to divide 879.75 by 100 because 100x=879.75

879.75 divided by 100 is 8.80

So now we know that they paid $8.80 just for the tip.

Add

Now all we have to do is add 8.80 to 58.65

58.65 plus 8.80 is 67.45

The Kerwoods paid $67.45 altogether.

A researcher measures daily driving distance from college and weekly cost of gas for a group of commuting college students. What
juin [17]

Answer:

There is a positive correlation between these two variables.

Step-by-step explanation:

Positive correlation is an association amid two variables in which both variables change in the same direction.  

A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.

As the distance covered by the vehicle increases the amount of gas consumed also increases. Thus, the weekly cost of gas will also increase.

Thus, there is a positive correlation between these two variables.

PLEASE HELP! I WILL MARK TOU AS BRAINLEIST!
san4es73 [151]

Answer:

a.Z(-2,1)

b.Z(1,1)

c.Z(-3,2)

Step-by-step explanation:

z(-2,3)

Imagine this point on a graph.

Translate it down two units :

the x stays -2, by going down the y decreases 2 so 3-2=1

Z(-2,1)

Translate Right three units : I'm assuming that we use the answer from the first translation

Z(-2,1)

The y doesn't change this time the x increases 3 since we're moving to the right.

Z(1,1)

Translate up 1 and left 4:

Z(1,1)

by moving up one we have Z(1,2) then by moving 4 to the left we get Z(-3,2)

Hope this helps :)
