First find 60% of 145 =
60% of 45 equals 87.
Now subtract 87 from 145.
145 - 87 = 58
So there were 58 girls.

Answer:
The sampling distribution of the sample proportion of adults who have credit card debts of more than $2000 is approximately normally distributed with mean
and standard deviation 
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean
and standard deviation 
In this question:

Then

By the Central Limit Theorem:
The sampling distribution of the sample proportion of adults who have credit card debts of more than $2000 is approximately normally distributed with mean
and standard deviation

Answer:
-5/2
Step-by-step explanation:
The average rate of change is the slope of the line between the two points. You can see from the graph that the slope is ...
slope = rise/run = -5/2
The average rate of change on the interval is -5/2.
