Answer:

  y DOES NOT vary directly with x

Step-by-step explanation:

If variation is direct, the ratio of y to x is a constant. Here, we have ...

  11/7 ≠ 13/8

so variation is not direct.

___

It appears that y = 2x-3, rather than y = kx for some k. The added constant (-3) means variation is not direct.

When asked to find a number one-tenth as large as another number, what operation would you use? What about when asked to find a
kherson [118]

Apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.

<u>Solution:</u>

Need to determine what operation is required to get one-tenth of a number and 10 times of a number

To get one tenth of a number, divide the number by 10.

For example to get one – tenth of 100, divide it by 10, we get 10 as a result.

\frac{1}{10} \times 100 = 10

To get ten times of a number, multiply the number by 10

For example 10 times of 10 = 10 x 10 = 100

Hence apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.

atroni [7]

Answer:

The probability of selecting two jelly filled donuts in a row is 1.08%.

Step-by-step explanation:

Since Elizabeth brought a box of donuts to share, and there are two dozen (24) donuts in the box, all identical in size shape and color, of which 3 are jelly filled, 6 are lemon filled and 15 are custard filled, and you randomly select one donut eat it and select another donut, to find the probability of selecting two jelly filled donuts in a row the following calculation must be performed:

3/24 x 2/23 = X

0.125 x 0.086 = X

0.01086 = X

Therefore, the probability of selecting two jelly filled donuts in a row is 1.08%.
