Answer:
Answer image is attached.
Step-by-step explanation:
Given rational expressions:
And the rewritten forms:
We have to match the rewritten terms with the given expressions.
Let us consider the rewritten terms and let us solve them one by one by taking LCM.
So, correct option is 3.
So, correct option is 1.
So, correct option is 2.
So, correct option is 4.
The answer is also attached in the answer area.

Given that Teresa has a 5 out of 8 chance of making a profit, and an expected value of $1.50 in profit each turn, in the long run she has a better chance of making money than losing it.
Given that Teresa is playing a game of chance in which she tosses a dart into a rotating dartboard with 8 equal-sized slices numbered 1 through 8, and the dart lands on a numbered slice at random, and this game is this: Teresa tosses the dart once, and she wins $1 if the dart lands in slice 1, $3 if the dart lands in slice 2, $5 if the dart lands in slice 3, $8 if the dart lands in slice 4, and $10 if the dart lands in slice 5, but she loses $5 if the dart lands in slices 6, 7, or 8, to find the expected value of playing the game, and determine what can Teresa expect in the long run, after playing the game many times, she must perform the following calculation:
- (1 + 3 + 5 + 8 + 10 - 5 - 5 - 5) / 8 = X
- 12 / 8 = X
- 1.5 = X
Therefore, given that Teresa has a 5 out of 8 chance of making a profit, and an expected value of $1.50 in profit each turn, in the long run she has a better chance of making money than losing it.

Answer:
a: The mean of 800 customers per day
b: See below
c: z = -1.43
d: 0.0764
e: Fail to reject the null
Step-by-step explanation:
b: The hypotheses are:
H0: µ = 800
HA: µ < 800 (claim)
The mean number of daily customers was 800. She feels the number of customers has decreased, so the alternate is mu is less than 800.
c: See attached photo for the calculation of the test statistic
d: The probability is on the z table. Find the decimal that corresponds to the z-value of -1.43, which is: 0.0764
e: Since 0.0764 > 0.05, we fail to reject the null hypothesis. There is not enough evidence to support the claim that the number of customers visiting the dealership has decreased.
