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

thats it
ENV MEASURE IS 50!!!!!!!!!!!!!!
Answer:
C.) -5 and 5
Step-by-step explanation:
Plug in -5 & 5 separately for x.
Plug in -5 for in the equation. Remember to follow PEMDAS. First solve for power, then multiplication.
2(-5)² = 50
2(25) = 50
50 = 50 (True).
Plug in 5 into the equation for x. Remember to follow PEMDAS. First solve for power, then multiplication.
2(5)² = 50
2(25) = 50
50 = 50 (True).

Answer:
x=6
Step-by-step explanation:
Put the problem into y=mx+b format we knoe the inital value b is 6 now m is 3 and y the overall price is 24. Use the distributive property.
24=6+3x y=6+3x y=24
-6 -6
<u>18</u>=<u>3x</u>
3 3
6=x
x=6
