Answer:

Step-by-step explanation:

A: if both 6 and 3 are red then the probability for a red is 2/6 or 1/3, if only 3 or 6 is a red then it is 1/6

B: spinning a 1 is 1/6 probability

C: spinning an odd number is 3/6 or 1/2 as half of the numbers are odd

D: 0 probability as there are no 9

Answer:

y= x-3

Step-by-step explanation:

The points are ;(0, -3), (5,2), (7,4), (10,7).

Plot the coordinates on a graph tool to visualize the graph

Select two points to find the slope ; take point (5,2) and (10,7)

m=Δy/Δx

Δy = 7-2=5

Δx=10-5 = 5

m=5/5 =1

The equation of the graph will be;

m= Δy/Δx

1=y-4/x-7

x-7 = y-4

x-7+4=y

x-3=y

y= x-3

Determine whether 81 − 49n4 is a difference of two squares. If so, factor it. If not, explain why.
Mumz [18]

We have

81-49n^4=9^2-(7n^2)^2

so this is indeed a difference of squares. Factorizing would give

81-49n^4=(9-7n^2)(9+7n^2)

making the answer D.

We can further factor the first term here and write

9-7n^2=3^2-(\sqrt 7\,n)^2=(3-\sqrt7\,n)(3+\sqrt7\,n)

but that's clearly out of the scope of this question.

Carol used 114 cups of flour in 2 muffins. How many cups of flour are needed to make 12 similar muffins?
son4ous [18]

Answer:

7 1/2 cups

Step-by-step explanation:

If Carol uses 1 1/4 cups of flour for 2 muffins, then she will need to repeat this conversion 6 times since she wants to make identical 12 muffins in all.

So, 1 1/4 * 6 = 7 1/2

Therefore, she needs 7 1/2 cups of flour

Hope that helps! :)
