Answer 2

Answer:

D. Subtract the sum of the three test scores from the product of 75 and 5, and divide the result by 2

Step-by-step explanation:

Alright imma try and make this as simple as possible.

My steps:

1) follow the answers steps:

(100 + 85 + 70) - (75 • 5) = -120

-120 divided by 2 = -60

Now, yes the answer is negative but check this out!

3) add 60 twice to 100, 85, and 70: ( 100 + 85 + 70 + 60 + 60) = 375

4) then divide 375 by 5: 375 divided by 5 = 75

Which is our mean! And there you have it! I really hoped this helped and your not confused. Good luck! :)

what is the value of k ?

Answers

Answer:

27-degrees

Step-by-step explanation:

these are vertical angles which are equal to each other *congruent

39 + k = 66 --> *subtract 39 from both sides*

k = 27

Answer:

27°

Step-by-step explanation:

Remember the angle opposite of another angle in two straight lines are equal

So 66=39+k

Then put k by itself by subtracting 39 from both sides

66-39=k

k=27°

A bag contains 5 yellow balls 3 red balls and 2 green balls. A ball is removed from the bag without looking, the colour recorded, and then returned the bag. A second ball is drawn and its colour is also recorded.

c) What would be the outcome of the 2 balls if it has a probability of 1/10?

Answers

Answer:

the two balls are yellow and green, in either order.

Step-by-step explanation:

P(Y) = 5/10 = 1/2

P(R) = 3/10

P(G) = 2/10

Since the only combination that makes a product of 1/10, so

P(Y)*P(G) = (5//10) * (2/10) = 10/100 = 1/10

So the two balls are yellow and green, in either order.

Find the slope and y-intercept of the line in the graph. Express the answers as simplified fractions, if
necessary

The slope is m =
The y-intercept is b =

Answers

Answer:

y-intercept: -3.

Slope:7/5

Step-by-step explanation: Y-intercept: The line crosses the y-axis at y=-3.

Slope: If you start from the point on the y-axis, -3, and count up 7 units, you reach 4 and then count right 5 units to reach a part of the line which touches a point. You go up 7 and go right 5 units. Therefore, the slope is 7/5. You go up, or rise, 7 units, and go right, or run, 5 units.
