Answer:
17
Step-by-step explanation:
5+2(6)= 5+12=17
3(j+4)-9=9
3j + 12 -9 =9
3j +3 =9
3j =6
j=2
Answer:
The minimum score required for an A grade is 83.
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 of 72.3 and a standard deviation of 8.
This means that 
Find the minimum score required for an A grade.
This is the 100 - 9 = 91th percentile, which is X when Z has a pvalue of 0.91, so X when Z = 1.34.




The minimum score required for an A grade is 83.
The answer is n equals five

$120
Step-by-step explanation:
<u><em>The complete question is</em></u>
Shelley designed the patio below, in which one side of the patio is a wall of the house. The length of each side of a square on the grid represents 3 meters.
Shelley plans to enclose the patio with fencing. If fencing costs $5 per meter, how much will it cost to enclose the patio?
$40
$60
$120
$180
<u><em>The picture in the attached figure</em></u>
Find the perimeter of the patio in units (without the wall of the house)

Multiply the perimeter by the cost of the fencing per meter
