Answer:
If a normal distribution is considered, a standard deviation (SD) is accounted for 34% (0.34 of population).
60 participants <=> p = 0.25
SD <=> p = 0.34
=> SD = 60 x 0.34/0.25 = 81.6 = ~82 participants.
Hope this helps!

I think its
x² - 2x + y² + 6y - 6 = 0
x² - 2x + y² + 6y = 6
(x² - 2x + 1) + (y² + 6y + 9) = 6 + 1 + 9
(x - 1)² + (y + 3)² = 16
center: (h, k) = (x, y) = (1, -3)
radius: 4
Answer: A, C, E
Step-by-step explanation:
Ignore the square root for now. 75/15 can be simplified into 25/5 (by dividing both by 3).
25/5 can be simplified into 5 (by dividing both by 5). 75/15 can also be simplified into 15/3 (by dividing both sides by 5). Now put the square roots back onto the simplified answers.
Gallons * 4
(Because there are 4 quarts in 1 gallon)
2.5 * 4 = 10.
There are 10 Quarts in 2.5 Gallons.
