Well first you need to find how many feet are in 6yd
Answer:
a) 150 pounds
b) 6.75
c) 156.25
d) 0.177
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 150 pounds
Standard Deviation, σ = 27 pounds
We are given that the distribution of weight of persons on campus is a bell shaped distribution that is a normal distribution.
a) expected value of the sample mean of their weights
b) standard deviation of the sampling distribution
c) average weight for these 16 people will result in the total weight exceeding the weight limit of 2500 points
d) P(sample of 16 persons on the elevator will exceed the weight limit)
Formula:
P(x > 156.25)
Calculation the value from standard normal z table, we have,
0.177 is the probability that a random sample of 16 persons on the elevator will exceed the weight limit.

Answer:
2/9 square yard
Step-by-step explanation:
You can see that the 1-yard square is divided into 18 rectangle. Of those, 4 are colored, so the fraction of the area that is colored is 4/18 square yard.
That fraction can be reduced by dividing 2 from each of those even numbers:
4/18 square yard = 2/9 square yard
The shaded area is 2/9 square yard.
okay so u only know one distance in this triangle! but u can find all three angles and get a side angle angle or SAA triangle and can solve with the law of cosines or sines from there
what is the side? that's 5 miles
what are the angles?
given north is at 90°, 57° west of north means one angle is 90° +50° = 147°
given south is 90° -69° = 21°
third angle is 180° -147° -21° = 12°
this means 12° is opposite 5 miles
hence distance from muffin observatory to chubacabra trail is 5 miles
distance from sasquatch point to muffin observatory is found from the law of sines
d /sin(147°) = 5 /sin(12°)
d = 5 *sin(147°) /sin(12°) = 13.10 miles
then distance from sqsuqtahc point to chubacapra trail is
d /sin(21°) = 5 /sin(12°)
d = 5 *sin(21°) /sin(12°) = 8.62 miles
