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:
AE Measure: 23.36 units
Step-by-step explanation:
BA: 20cm
BC:20cm
BE:10cm CE: 10cm
a^2 +b^2=c^2
BE^2 +BA^2 = AE^2
√100 + √400 = √500
AE^2 = √500 = 23.36
AE = 23.36 unit

The values for x and y are respectively given as
This is further explained below.
<h3>What is the values for
x and y ?</h3>
Generally, the equation for secent is mathematically given as
Therefore
80 = 130-x
x = 50
b) To Solve for y Now we find a measure of arc CD
ArcCD = 360-130-50
ArcCD = 180
In conclusion,(1/2) of the arc measure is equal to the angle that is on and inside a circle.
y = 180/2
y= 90

Answer:
1. 10 weeks
Step-by-step explanation:
Apparently, we want to find the number of weeks (w) that Kaitlyn must save $6 in order to have a total of $60.
... $6 × w = $60
Divide by $6 to get ...
... w = $60/$6 = 10
Kaitlyn must save for 10 weeks (if she starts with a balance of 0).

<em>Comment on the problem statement</em>
The problem reads like we came in somewhere in the middle of it. We don't know what other steps you've been asked to perform, or any of the details of the problem you're asked to solve. We don't have Kaitllyn's initial balance, for example, which is essential to determining how long she must save. (If Kaitlyn's initial balance is $33, for example, she must only save for 4.5 weeks.)
