Answer: 0.0427
Step-by-step explanation:
Given : The area under the standard normal curve to the left of z = -1.72 is 0.0427
We know that the normal curve is a bell shaped curve that is symmetric such that half of the data falls to the left of the mean (Mean lies at the middle of the curve) and half of data falls to the right.
Now, z=-1.72 lies on the left side and z=1.72 lies right side.
Since, normal curve is symmetric and the magnitude of the values if same , then the area under the standard normal curve to the left of z = -1.72 is equals to the area to the right of z = 1.72 is 0.0427
Therefore, the area under the standard normal curve to the right of z = 1.72 is 0.0427

The answer would be 16 3/4 divided by 3 7/8
Distance traveled is directly proportional to time traveled.
d α t
d = kt, where k is constant of proportionality.
Using d = 93 miles and t = 15 hours
93 = k(15)
15k = 93
k = 93/15 = 6.2
Hence variation equation is: d = kt, since k = 6.2.
d = 6.2t
Distance traveled in 24 hours:
d = 6.2t
d = 6.2*24
d = 148.8
Distance traveled is 148.8 miles.
The shortest side is 16. Tip: add up all the sides to equal the perimeter.
