Answer:
30 milk chocolates
Step-by-step explanation:
42 ÷ 7 = 6 - a fraction of the chocolates
6 x 5 = 30 - the milk chocolates (7+5 = 12 which is the whole fraction).
15 x 7 days = 105 then multiply 5 weeks. 5 x 105 = 525 miles
Answer:
A customer who sends 78 messages per day would be at 99.38th percentile.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Average of 48 texts per day with a standard deviation of 12.
This means that 
a. A customer who sends 78 messages per day would correspond to what percentile?
The percentile is the p-value of Z when X = 78. So



has a p-value of 0.9938.
0.9938*100% = 99.38%.
A customer who sends 78 messages per day would be at 99.38th percentile.
Answer:
330
Step-by-step explanation:
C=100
X=10
100(3)+10(3)=330
Answer:
C
Step-by-step explanation:
A: You can combine like terms. 2x + 3x = 5x. 2.5 + 3 = 5.5 A = 5x - 5.5
B: You can use distributive property. 5x - 5.5
C: If you use the distributive property you get 5x + 27.
D: D is 5x - 5.5
So the only one that does not equal 5x - 5.5 is C.
Hope this helps :)
