Answer:

-1 is your answer,

Step-by-step explanation:

first of all, add all those scores

-3 + 1 + -2 + -4 + 3 = -5

and for average, there is 5 rounds, so divide by 5

hence answer is -5 / 5 - = -1

HELP!!! I NEED THE ANSWER!

Fiesta28 [93]

Things we know: every pound of cherries cost four dollars.

We don't know how much the mother got and it is represented by the variable 'r'. But we do know how many pounds the dad got. He got two pounds.

We know the total cost the mom had to pay which is 4 * r and the amount the dad paid is 4 * 2 or 8.

Now we want to make an algebraic expression that represents how much more the mother paid than the father.

Final answer:

8 - (4 * r)

Hope this helps!

By comparing medians which person went to the movies the most per month

Nimfa-mama [501]

I think they all went to the movies equally per month if you simply compare medians? Since in the second chart, they each have a median of 2 times per month, that makes it equal. If you aren’t sure if this is correct, you have to order how many times each person went to the movies, from least to greatest. For example, John’s would be 1,1,1,2,2,2,2,3,3,3,4,5. Then you would start crossing numbers off from each end. First you would cross off 1, then 5, and then 1, and then 4, and keep going until you reach the number in the very middle, which is 2. Do this with all of the other people, and check if everybody has 2 for a median. I believe they do, however it’s always best to check and be safe. Good luck

Drew has 50 red,green,and blue marbles. he has six more red marbles than blue marbles and four fewer green marbles than blue mar

astraxan [27]

Red = r

Blue = b

Green = g

Step 1: Write as algebraic equations.

r = b + 6

g = b - 4

Step 2: Merge the two equations together to form one, by adding them together.

r + g = b + b + 6 - 4

Step 3: Simplify.

r + g = 2b + 2

Step 4: Make b the subject.

2b + 2 = r + g

2b = r + g - 2

b = 0.5(r + g - 2)

ANSWER

b = 0.5(r + g - 2)

the line with a slope of 1/3 and a y- intercept of - 15 intersects the line passing through which of these pairs of points?

stich3 [128]

Answer:

Options (C), (D) and (E)

Step-by-step explanation:

Slope of the given line = $\frac{1}{3}$

Any line having same slope will be parallel to the given line otherwise the lines will intersect.

Therefore, we will find the slope of the lines passing through two points given in the options.

Option A

Slope of the line passing through (12, -13) and (15, -12)

m = $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{-13+12}{12-15}$

= $\frac{1}{3}$

Therefore, both the lines are parallel having no point of intersection.

Option B

Slope = $\frac{-9+7}{18-24}$

= $\frac{1}{3}$

Both the lines are parallel having no point of intersection.

Option C

Slope = $\frac{-20+21}{15-18}$

= $-\frac{1}{3}$

Therefore, both the lines will intersect.

Option D

Slope = $\frac{-15+14}{30-36}$

= $\frac{1}{6}$

Both the lines will intersect each other.

Option E

Slope = $\frac{-11+10}{24-30}$

= $\frac{1}{6}$

Both the lines will intersect each other at a point.

Options (C), (D) and (E) are the correct options.

How do You graph : y-10= -5x?

miv72 [106K]

Equation:

y - 10 = -5x

Solve:

(y - 10) + 10 = (-5x) + 10

y = -5x + 10

Remember the formula (Slope Intercept Form):

y = mx + b

m = Slope (Rise/Run)

b = Y-intercept

So your graph would look something like the attached image:
