Convert the fraction 3/4 to decimal form to get 3/4 = 0.75
To factor out 3/4, we divide each term by 3/4 or 0.75
It might be easier to divide by 0.75 to avoid two division symbols
So (3/4)z+6 = 0.75z+6
Divide each term (0.75z and 6) by 0.75 which is what we want to factor out
0.75z/0.75 = z
6/0.75 = 8
Therefore,
0.75z+6 = 0.75*(z+8)
Note how we can distribute the 0.75 back through to each term inside (z and 8) and we'll end up with 0.75z+6 again.
The answer in fraction form is

which is 3/4 outside the parenthesis multiplied by the group (z+8)
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
I’m not sure but I think graphing it would help I really don’t know what to say
I did this in my head but the answer is $36 45/5 is 9 9*4 is 36. And if you add another it totals to 45. Thus the answer is $36.
