A parking garage bases its prices on the number of hours that a vehicle parks in the garage.

yarga [219]

The pricing scheme of the function is (a) The first two hours cost $2, between two hours and six hours cost $2 per hour, and all hours after that cost $1.

<h3>How to determine the pricing scheme?</h3>

The points are given as:

Constant = (0,2) to (2, 2)
Another = (2,2) to (6,10)
Another = (6,10) to (7,11)

The constant interval implies that the first two hours cost $2

Next, we calculate the slope/rate of the other points.

This is done using

m = (y2 - y1)/(x2 - x1)

So, we have:

m1 = (10 - 2)/(6 - 2) = 2

m2 = (11 - 10)/(7 - 6) = 1

This means that:

The next 4 hours are charged for $2 per hour
All hours after that cost $1

Hence, the pricing scheme of the function is (a)

Find the probability of picking 3 consonants and 2 vowels when 5 letters are picked (without replacement) from a set of alphabet

schepotkina [342]

Step-by-step explanation:

picking 3 consonants and 2 vowels when 5 letters are picked (without replacement) from a set of alphabet tiles.

There are 26 letters in alphabet

number of consonants = 21 and number of vowels = 5

We need to pick 3 consonants from 21 consonants

Probability of picking 1 consonant from 26 alphabets = 21/ 26

after picking 1 consonant then number of consonant becomes 20

Probability of picking second consonant from 25 alphabets = 20/ 25

Probability of picking third consonant from 24 alphabets = 19/ 24

We need to pick 2 vowels from 5 vowels

Probability of picking 1 vowel from remaining 23 alphabets = 5/ 23

Probability of picking second vowel from remaining 22 alphabets = 4/ 22

Now multiply all the probabilities

$\frac{21}{26} *\frac{20}{25} *\frac{19}{24} *\frac{5}{23} *\frac{4}{22}$

= 0.02022
