Answer:
A
Step-by-step explanation:
-When the function moves to the right or left to the x axis, the number has to be in "( )"
-If it moves to the right, you SUBTRACT the amount of units
-It it moves to the left, you ADD the amount of units.
So in this case, it is moving to the right 12 units so it is 
Answer:
The percentage error of measurement is 5.63 %
Step-by-step explanation:
Given as :
The measure length of the fence = 150 feet
The actual length of the fence = 142 feet
Let the percentage error in measurement = x
So, x =
×100
Or, x =
×100
or, x =
×100
or, x = 5.63 %
Hence The percentage error of measurement is 5.63 % Answer
The correct answer is the third choice : 25/9
Answer:
The Z-score for that day's temperature is 2.41, and since Z > 2, this temperature is significantly high.
Step-by-step explanation:
Z-score:
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.
If
, the measure X is significantly high(Z > 2) or significantly low(Z < -2).
The mean high temperature on a particular day in January is 31 degrees F and the standard deviation is 8.7 degrees.
This means that 
One year, the temperature was 52 degrees F on that day.
This means that
.
What is the Z-score for that day's temperature?



The Z-score for that day's temperature is 2.41, and since Z > 2, this temperature is significantly high.
The answer is b, f[c(p)]=0.9265p.
f[c(p)]=f(0.85p)=1.09(0.85p)=0.9265p
