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:
x = 8
Step-by-step explanation:
Let's solve your equation step-by-step.
−6+7x=50
Step 1: Simplify both sides of the equation.
7x−6=50
Step 2: Add 6 to both sides.
7x−6+6=50+6
7x=56
Step 3: Divide both sides by 7.
7x/7 = 56/7
x=8
have a wonderful day

Answer:
The length of the hypotenuse is equal to 2 units
Step-by-step explanation:
we know that
If the right triangle is formed inside the unit circle (inscribed triangle)
then
the hypotenuse of the right triangle must be equal to the diameter of the unit circle
we have
r=1 unit
D=2*(1)=2 units
therefore
The length of the hypotenuse is equal to 2 units
Answer:50%
