Answer:
Between 38.42 and 49.1.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 43.76, standard deviation of 2.67.
Between what two values will approximately 95% of the amounts be?
By the Empirical Rule, within 2 standard deviations of the mean. So
43.76 - 2*2.67 = 38.42
43.76 + 2*2.67 = 49.1
Between 38.42 and 49.1.

Answer:
4, see below :)
Step-by-step explanation:
We can rewrite the equation into:
3.5 + 2 - 1.5
First we add 3.5 and 2
3 and 2 are in the ones place so:
5, and then you added the .5
5.5
Then:
5.5 - 1.5
First we subtract the tenths place so:
.5 - .5 = 0
Then the ones:
5 - 1 = 4
