The answer is A
your expression said 5×20=100 +3×20=60 So 100+60=160
now the option A is5+3=8 then 8×20=160 there the same product
Answer:
a. at least 20%, when in fact, it is less than 20%.
Step-by-step explanation:
Type 1 Error is to reject null hypothesis when it is actually true.
Here the null hypothesis is fewer than 20% of Evergreen Valley College (EVC) students attended the show.
In mathematics fewer than 20% means less than 20%.
So the null hypothesis is that less than 20 % students attended the show.
We have to reject this hypothesis .
We can reject this hypothesis when we assume that the % is greater than or equal to 20 %
At least 20% means greater than or equal to 20%.
So the best choice is option a.
at least 20%, when in fact, it is less than 20%.

<h3>AUB = { 2, 3, 4, 6, 8, 9, 10, 12}</h3>
<em><u>Solution:</u></em>
The complete figure of question is attached below
From figure,
Write all elements from set A
A = {3, 6, 9, 12}
Write all elements from set B
B = {2, 4, 6, 8, 10, 12}
AUB means A union B
AUB means set of all the numbers combined with set A and set B
Combine set A and B
AUB = { 2, 3, 4, 6, 8, 9, 10, 12}
Thus AUB is found
