Answer:
Lower quartile: 72
Upper quartile: 84
Step-by-step explanation:
Follow the instructions in the hint to solve the problem.
First, divide the data set into halves:
70, 70, 72, 75, 79
80, 80, 84, 89, 95
Now, find the median of the two sets. The median of set #1 is 72, as that is the number in the middle of the data.
The median of set #2 is 84 for the same reason.
Upper and lower quartiles are just different words for upper and lower medians. The upper quartile is the higher number, and the lower quartile is the lower number.
Answer:
A
Step-by-step explanation:
So we have the piecewise function:
And we want to find f(8).
Since our input value is 8, choose the equation that fits our input.
The first equation demand x to be less than 3. 8 is not less than 3, so we won't use that.
The second equation demand x to e greater than or equal to 3 and less than 8. 8 is <em>not</em> less than 8. So, we won't use that.
The third equation demands x to be greater than or equal to 8. 8 is greater than or equal to 8, so we'll use the third equation.
So:
There're nothing more to do, we're done :)
The answer is A.

Answer:
food A has fewer calories
Step-by-step explanation:
food b has 250 cal. in 2/3 of a serving and food a has only 150 in 3/4 of a serving, and because it is 3/4 we can know that the last amount of cal. in food a is 50, meaning that with all the calories in the full serving, it has less calories then food b with a fraction of the calories. food a is the answer
Answer:
The answer is 17 or x is 17
