Answer:
3 inches
Step-by-step explanation:
Bishop can pole-vault 189 inches
The height needed is 16 x 12 inches = 192 inches
He needs to Jump 192 - 189 = 3 more inches
Answer:
3 1/3 gallons per minute
Step-by-step explanation:
We can use ratio's to solve this problem. We will put gallons on top and time on the bottom
5/6 gallons x gallons
-------------------- = -------------
1/4 minute 1 minute
Using cross products
5/6*1 = 1/4 x
Multiply by 4 on each side
5/6 * 4 = 1/4 *4 x
20/6 = x
Dividing the top and bottom by 2
10/3 =x
Changing this back to a mixed number
3 goes into 10 3 times with 1 left over
3 1/3 gallons per minute
Answer:
(a) 3, 5 and 6
Step-by-step explanation:
In the experiment, 43 are to be given a gel that contains the tooth-whitening chemicals while the remaining 42 are to be given a placebo. Therefore, a placebo is used.
The 43 that will receive the gel are to be selected randomly.
After the experiment, the whiteness of the two groups will be compared to see the effect of the gel.
Therefore for the experiment to be completely random, 3, 5, and 6 apply.
(b)
For the experiment to be double-blind, the researchers who will evaluate the whiteness and interact with the subjects, and the subjects would not know which subjects received either the whitening gel or the placebo.
Their is only one y for each x. you could also use the vertical line test, you could use the graphing calculator.
