Answer: 0.935

Explanation:

Let S = z-score that has a probability of 0.175 to the right.

In terms of normal distribution, the expression "probability to the right" means the probability of having a z-score of more than a particular z-score, which is Z in our definition of variable Z. In terms of equation:

P(z ≥ S) = 0.175 (1)

Equation (1) is solvable using a normal distribution calculator (like the online calculator in this link: http://stattrek.com/online-calculator/normal.aspx). However, the calculator of this type most likely provides the value of P(z ≤ Z), the probability to the left of S.

Nevertheless, we can use the following equation:

P(z ≤ S) + P(z ≥ S) = 1
⇔ P(z ≤ S) = 1 - P(z ≥ S) (2)

Now using equations (1) and (2):

P(z ≤ S) = 1 - P(z ≥ S)
P(z ≤ S) = 1 - 0.175
P(z ≤ S) = 0.825

Using a normal distribution calculator (like in this link: http://stattrek.com/online-calculator/normal.aspx),

P(z ≤ S) = 0.825
⇔ S = 0.935

Hence, the z-score of 0.935 has a probability 0.175 to the right.

An amusement park charges a $20 admission fee and $3 for each ride. Which equation can be used to determine c, the total cost of

PtichkaEL [24]

Answer:

C = 3n+20

Step-by-step explanation:

C= The Cost

n= the number of rides

So if you get on 2 rides

that would be $6

because 3x2=6

or 3+3

and just add in the 20 to get in

so the sum is

26 if you were to get on 2 rides
