Hi there! For this question, we will have to divide. When it comes to dividing fractions, we keep, change, flip. In other words, keep the first fraction the same, change division into multiplication, and flip the second fraction over by its reciprocal. In this case, 3/5 stays the same and 6/1 becomes 1/6. 3/5 * 1/6 is 3/10 or 1/10 in simplest form. There. There are 1/10 gallon of juice in each glass.

Answer:
56, 60, 64
Step-by-step explanation:
The middle of the three numbers is their average: 180/3 = 60. The other two will be 4 more or less than this.
The numbers of interest are 56, 60, 64.

<em>Additional comment</em>
For "consecutive integer" problems, it is often useful to work with the average of the numbers. The average will be the middle number of an odd number of numbers (as here), or will be halfway between the two middle numbers if their number is even.
Even if you bother to write equations, it can work to do that in terms of the average value (middle number): (x -4) +(x) +(x +4) = 180 in this case.
In order to find 150% of something, you would add half of the value to itself. so for example, 150% of 9 would be 13.5 because 4.5 is half of 9 and 4.5 • 9 is 13.5. hope this helps!!
Answer:
2.542
Step-by-step explanation:
Given the data :
Customer Pre-training Survey, x1 __Post-training Survey, x2 __ difference, d = (x2-x1)
A 6 8 2
B 5 5 0
C 10 10 0
D 7 10 3
E 6 8 2
F 5 6 1
G 2 8 6
This is a paired test as each subject has two different data values :
Difference in score, d :
dbar = Σd / n
dbar = (2+0+0+3+2+1+6) /
dbar = 14 / 7
dbar = 2
Standard deviation of d ; Sd = √[Σ(d - dbar)²/n-1]
Using calculator ; Sd = 2.082
Test statistic = dbar ÷ (Sd/√n)
Test statistic = 2 ÷ (2.082 / 7)
Test statistic = 2 ÷ 0.7869220
The statistic = 2.5415
