Answer:
A) Y=3X -2
Step-by-step explanation:
Answer:
80%.
Step-by-step explanation:
Given the following probabilities:
- P(Micheal Being admitted to French), P(F)=50%
- P(Micheal Being admitted to Spanish), P(S)=50%
In Probability Theory, when we have BOTH , we mean the intersection of the probabilities. Therefore:
- P(Micheal Being admitted to BOTH French and Spanish),

We want to determine the probability that he will be enrolled in either French or Spanish (or possibly both).
Probability of either A OR B =
From Probability Theory:

The probability that he will be enrolled in either French or Spanish (or possibly both) is 80%.
Answer:
- 2x + 18
Step-by-step explanation:
Given
4x - 2(3x - 9) ← distribute
= 4x - 6x + 18 ← collect like terms
= - 2x + 18 OR 18 - 2x
Answer:
99% confidence interval will be wider because as the level of confidence increase the width increases as well and the standard error decreases
Step-by-step explanation:
The confidence interval is directly proportional to the sample size hence the 99% confidence interval will be wider than the 95% confidence interval of the sample of 120 college students
using a 99% confidence interval gives a more accurate result than a 95% confidence because the standard error decreases with increase in confidence interval
6.31 is a rational number.
