n(A-B) denotes elements which are in A but not in B
n(Au B) denotes elements in A and B
n(AnB) denotes elements that are common in A and B
Now I will add one more set
n(B-A) which denotes elements in B but not in A
So, n(AuB) = n(A-B) + n( B-A) +n(AnB)
70 = 18 +n(B-A) + 25
70 = 43 + n(B-A)
n(B-A) = 70-43
n(B-A) = 27
So, n(B) = n( B-A) + n( AnB)
= 27+25
= 52
Answer:
The answer is below
Step-by-step explanation:
There are various tips or suggestions on how others can represent real-life situations using rational functions, one of them is the application of a work problem formula.
By using the work problem formula, one can measure the time it will take different people working at different speeds to complete the work. With the formula w =r*t. Where w = work done, r = rate of work donee, and t = time
Answer:
There is sufficient evidence to support the claim that the mean temperature is different from 45 degrees
Step-by-step explanation:
Given : Claim : The mean temperature of the refrigerators is different from 45 degrees
To Find :Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms.
Solution:
Claim : The mean temperature of the refrigerators is different from 45 degrees
So, Null hypothesis : 
Alternate hypothesis : 
We are given that the conclusion is to reject the null hypothesis.
So, we can say that the claim is true that mean temperature is different from 45 degrees.
There is sufficient evidence to support the claim that the mean temperature is different from 45 degrees
Answer:
48.60 miles per hour (MPH)
Step-by-step explanation:
:)
This looks like the base graph of tangent x that is shifted 3 units up.
So the graph is simply:
y = tanx + 3
