Answer:
put ur protactor from the middle to where its up to then look at where the line is and you will get your answer
Using the normal distribution, it is found that:
a) The pilot is at the 72th percentile.
b) 19.13% of pilots are unable to fly.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
.
Item a:
The percentile is the <u>p-value of Z when X = 74.2</u>, hence:


Z = 0.59
Z = 0.59 has a p-value of 0.7224.
72th percentile.
Item b:
The proportion that is able to fly is the <u>p-value of Z when X = 78 subtracted by the p-value of Z when X = 70</u>, hence:
X = 78:


Z = 2
Z = 2 has a p-value of 0.9772.
X = 70:


Z = -0.96
Z = -0.96 has a p-value of 0.1685.
0.9772 - 0.1685 = 0.8087 = 80.87%.
Hence the percentage that is unable to fly is:
100 - 80.87 = 19.13%.

<h2>
Answer:</h2>
5 3/4 inches
<h2>
Step-by-step explanation:</h2><h3>Known :</h3>
- It snowed 1 3/8 in the morning
- It snowed 4 3/8 in the morning
<h3>Asked :</h3>
- The total amount of the snowfall
<h3>Solution :</h3>
We can add the amount of snowfall in Belmont in the afternoon and in the morning to find the total amount of snowfall.
4 3/8 + 1 3/8
= (4 + 1) + (3/8 + 3/8)
= 5 + 6/8
= 5 6/8
= 5 3/4
<h3>Conclusion :</h3>
The total amount of snowfall is 5 3/4 inches
Alternate interior: middle right (the numbers 1 and 2 are in between the two lines, and are on opposite sides of the slanted 'vertical' line
Alternate exterior: First one ( as stated for alternate, the 2 numbers are on opposite sides. both numbers have to be outside the 2 lines
Corresponding: bottom, and middle left ( these are on the same side ( all i know how to explain it as) )
None of these: top right ( literally, none of these)
hope this helps
