Answer:

Step-by-step explanation:
x - number of adults
y - number of campers
<em>The room for 200 people</em>: x + y ≤ 200
<em>Each adult costs $4, and each camper costs $3</em>: 4x and 3y
<em>A maximum budget of $750</em>: 4x + 3y ≤ 750
Answer:
Ordering a soft drink is independent of ordering a square pizza.
Step-by-step explanation:
20% more customers order a soft drink than pizza, therefore they cannot be intertwined.
Given: P(A)=0.5 & P(B)=.7
P(A∩B) = P(A) × P(B)
= 0.5 × .7
= 0.35
P(A∪B) = P(A) + P(B) - P(A∩B)
= 0.5 + .7 - 0.35
= 0.85
P(AΔB) = P(A) + P(B) - 2P(A∩B)
= 0.5 + .7 - 2×0.35
= 0.5
P(A') = 1 - P(A)
= 1 - 0.5
= 0.5
P(B') = 1 - P(B)
= 1 - .7
= 0.3
P((A∪B)') = 1 - P(A∪B)
= 1 - 0.85
= 0.15
<u>ANSWER</u>

<u>EXPLANATION</u>
The given compound inequality is

We need to simplify this inequality so that we can obtain x standing alone between the inequality signs.
We add 6 through out the inequality.

This simplifies to:

We now divide through by -3 and reverse the inequality sign.

We now simplify to get:

Add some of them or all of them to your sum of 47.75, if either or exceeds the limit then that is what left out.
Answer:
A Type II error is when the null hypothesis is failed to be rejected even when the alternative hypothesis is true.
In this case, it would represent that the new program really increases the pass rate, but the sample taken is not enough statistical evidence to prove it. Then, the null hypothesis is not rejected.
The consequence is that the new method would be discarded (or changed) eventhough it is a real improvement.
