We can see that the terms 15x and 6 share a common divisor, 3. By the Distributive Property, we can take the 3 out of both terms and set it in front of a set of parentheses containing the sum of the two terms. This would look like this:

Thus, our answer is C, 3(5x + 2).
Answer:
There is significant learning
Step-by-step explanation:
This is a test on comparison of a single proportion with a hypothesized proportion.
The subject of interest is whether rats really learn.

(Right tailed test)
n =100
Sample proportion p = 0.62
Std error of p assuming H0 to be true is
= 
p difference = 0.12
Z statistic = p difference/std error = 
p value = 0.0082
Since p <0.01, our alpha we reject null hypothesis
There is significant learning
Answer:
1,075 ft
Step-by-step explanation:
So you need to find area
15 x 25 =375 ft
35 x 20 = 700 ft
add together to get total of both
700 + 375 = 1,075
Hopefully im right!
If your trying to find the original amount all you have to do is add the 12 to the 52 to find out, that is 64!
The answer is going to be A) 9:14
