Answer:
The answer to your question is : 33.3 (Rounded).
Step-by-step explanation:
I got this answer by dividing 19.6 by 20, which gave me 0.98.
Then, I multiplied 0.98 by 34, which gave me 33.32.
After rounding, 33.3 is your answer.
Hope this helped!!
Answer:
88.88% probability that it endures for less than a year and a half
Step-by-step explanation:
Problems of normally distributed samples can be 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 question, we have that:

The next career begins on Monday; what is the likelihood that it endures for less than a year and a half?
One year has 52.14 weeks. So a year and a half has 1.5*52.14 = 78.21 weeks.
So this probability is the pvalue of Z when X = 78.21.



has a pvalue of 0.8888
88.88% probability that it endures for less than a year and a half
point R ((:
reason being (-5,-6) over the y axis is (5, -6)
The 5 - number summary :
Min____ Q1 ___ median ____ Q3 ____ max
7 ______ 9 _____ 12 _______ 15 _____ 18
Answer:
Hence, from the 5 number summary, about 75% of sons have fewer than 15 stylist.
Step-by-step explanation:
Explaining the table :
Minimum number of stylist salons have = 7
Maximum number of stylist = 18
Q1 = first quartile, (25 /100) ;About 25% of salons have fewer Than 9 stylist
Q2 = second quartile or median ; About 50% of salons have fewer Than 12 stylist
Q3 gives the 75th percentile value.
Q3 = third quartile (75/100) ; About 75% of salons have fewer Than 15 stylist
For the first one is definitely 0.12
The second one I was having trouble with, but I know it is not .25 or .75. Looking at the leftover answers I would say .36 because I already used .12. Also .52 and .25 are the givens.
