Answer: Choice B</h3>
angle B = 118, a = 17, c = 18
==========================================================
Explanation:
Use the given angles to find angle B.
A+B+C = 180
B = 180-(A+C)
B = 180-(30+32)
B = 118
Now use the law of sines to find side 'a'
Make sure your calculator is in degree mode.
a/sin(A) = b/sin(B)
a/sin(30) = 30/sin(118)
a = sin(30)*30/sin(118)
a = 16.9885507603356
a = 17
Follow similar steps to find side c
c/sin(C) = b/sin(B)
c/sin(32) = 30/sin(118)
c = sin(32)*30/sin(118)
c = 18.005120638611
c = 18
Answer:
a
The 95% confidence interval is 
b
The sample proportion is 
c
The critical value is 
d
The standard error is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 200
The number of defective is k = 18
The null hypothesis is 
The alternative hypothesis is 
Generally the sample proportion is mathematically evaluated as

Given that the confidence level is 95% then the level of significance is mathematically evaluated as



Next we obtain the critical value of
from the normal distribution table, the value is

Generally the standard of error is mathematically represented as

substituting values


The margin of error is

=> 
=> 
The 95% confidence interval is mathematically represented as

=> 
=> 
Answer:
2 hours
Step-by-step explanation:
Downers grove = 5 inches of snow + 6 inches every hour
= 5 + 6h
Woodridge = 13 inches + 2 inches every hour
= 13 + 2h
Where,
h = number of hours
In how many hours will the snowfall of the towns be equal?
Equate the snow falls of the towns
Downers grove = Woodridge
5 + 6h = 13 + 2h
Collect like terms
5 - 13 = 2h - 6h
8 = 4h
Divide both sides by 4
h = 8 / 4
= 2
h = 2 hours
The snowfall of the towns will be equal in 2 hours
