The answer is A f(x)=-2x + 70
The $100 budget, $10 entrance fee, as well as the $20 spent on food are considered to be constants with the budget being a positive and the money spent on the entrance and food as negatives. This provides you with a positive 70. The variable x here is the number of rides your friend might take and the -2 multiplied to it is the money to be spent per ride. 

Example:
When your friend has ridden a total of 5 rides, x = 5 therefore 

-2(5) + 70 = 60

Your friend upon going on 5 rides would have $60 left.

Masteriza [31]

Answer:

  • <em>D. The game is not fair because the probability of Hal drawing a winning letter is less then the probability of Renee drawing a winning letter </em>

Explanation:

The word is not probably, which has 8 letters, but probability, which has 11 letters

<u>1. Hal</u>

Probability of drawing a vowel

  • The vowels are:  o, a, i, i, and y: 5

  • The total number of letters in the bag is 11.

  • Probability of vowel = 5 / 11

<u>2. Renee</u>

Probability of drawing a consonant

  • The consonants are: p, r, b, b, l, t, and y: 7

  • Probability of a drawing a consonant: 7 /11

<h2>Conclusion</h2>

As you see, the probability of drawing a vowel (5/11), which is the winning letter for Hal, is less than the probability of drawing a consonant (7/11), which is the winning letter of Renee. Then,

  • The game is not fair because the probability of Hal drawing a winning letter is less then the probability of Renee drawing a winning letter.

Whats is 0.000001 written as a power of ten
siniylev [52]
You need to move the decimal point to be at 1.

Since this is a decimal, the power will be negative.

I had to move the decimal 6 places.

So,

1^-6

I hope this helps!
