Answer:
B) y=3x
Step-by-step explanation:
2 x 3 = 6
3 x 3 = 9
4 x 3 = 12
You can find y by multiplying the x by 3. The relationship between the x and y is proportional. For example, lets say my x is 20, my y would be 60. 20 x 3 = 60.
If you are still unsure, remember constant of proportionality is k=y/x, so your constant is 3.
Answer:
The medium bucket can hold 5 and 1/6 cups of popcorn.
Step-by-step explanation:
Remember that for mixed numbers, like "4 and 1/5", the way of writing that number is (4 + 1/5).
Now, let's solve the question:
We know that the large bucket holds (15 + 1/2) cups.
We also know that the medium bucket holds 1/3 of the large bucket, and we want to know how many cups does the medium bucket hold.
This is just (1/3) times the amount that the large bucket holds, so we have:
(1/3)*(15 + 1/2) cups
Using the product distributivity, we can write:
(1/3)*(15 + 1/2) cups = ( (1/3)*15 + (1/3)*(1/2) ) cups = (5 + 1/6) cups
Then we can conclude that the medium bucket can hold 5 and 1/6 cups of popcorn.
Since the ratio is 5:4, they had to multiply 5x11 to get the 55. Now multiply the 4x11 to get 44. When you add the 55 and 44 that's 99 which only leaves 1 for the independent.
Answer:
-2.25
Step-by-step explanation:
We have that the mean (m) is equal to 500, the standard deviation (sd) 20
They ask us for P (x <455)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / sd
We have all these values, replacing we have:
z = (455 - 500) / (20)
z = -2.25
