Answer:
The minimum score required for an A grade is 88.
Step-by-step explanation:
Problems of normally distributed samples are 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 problem, we have that:

Find the minimum score required for an A grade.
Top 12%, which is at least the 100-12 = 88th percentile, which is the value of X when Z has a pvalue of 0.88. So it is X when Z = 1.175.




Rounding to the nearest whole number
The minimum score required for an A grade is 88.
Answer:
The answer to your question is 440 in³, this is my result I can not see the height in the picture I think the number is 40 in
Step-by-step explanation:
Data
length of a side = 6 in
height = 40 in Is really 40?
Volume of a square pyramid = ?
Process
1.- Calculate the area of the base
Ab = 6 x 6
= 36 in²
2.- Calculate the volume of the Pyramid
Volume of a square pyramid = 1/3 (36 x 40)
= 1440 / 3
= 480 in³
Answer:
1.4
Step-by-step explanation:
This is because the 4 is in the hundreds place but the 0 is in the hundreds in the second one.
