Answer:
d. 76.98%
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What percentage of MBA's will have starting salaries of $34,000 to $46,000?
This is the pvalue of Z when X = 46000 subtracted by the pvalue of Z when X = 34000. So
X = 46000
has a pvalue of 0.8849
X = 34000
has a pvalue of 0.1151
0.8849 - 0.1151 = 0.7698
So the correct answer is:
d. 76.98%
Answer:
The reason for the decreasing sequence is 
the sum of the sequence is -243
Step-by-step explanation:
Note that the numbers are decreasing so we will use the following formula to find the sum:
S∞=
,
where t1 is equal to the first number of the sequence and q is the reason that gives the following results.
to find q this form is used;
q= 
then we replace in the formula of the sum to find the total

Answer:
1 1/2 gallons is equivalent to 6 quarts.
Explanation:
Neither is greater or less because they are equivalent to eachother. You can find out how many quarts there are in a gallon by multiplying the gallons by 4. In this situation: 1.5 * 4 = 6, so we know that 1 1/2 gallons is equivalent to 6 quarts.
