Answer:
The cut-off dollar amount is $328.
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.
Mean cost of $328, standard deviation of $82.
This means that 
If you want to be in the bottom 50%, what will be the cut-off dollar amount?
The 50th percentile, which is X when Z has a pvalue of 0.5. So X when Z = 0.




The cut-off dollar amount is $328.
R = A / tetha
70° × pi/180 = radian
radian = 1.222 rad
3 = A / 1.222
Arc = 3.7 meter
i am a mathematics teacher. if anything to ask please pm me
Answer:
7 P.M.
Step-by-step explanation:
Time at which the walk was begun = 4 p.m.
Finished after rotating the clock 90° i.e. = 3 hours
Thus,
The time at which the task finished = 4 p.m. + 3hours
= 7:00 PM
Solve for h
V = lwh
Divide lw on both sides, and you get
V / (lw) = h
Answer: b
9am to 4 pm is 7 hour and you use the total cost divid by hours you can get you answer which is 4.12 per hour
