aalyn [17]

2 1/2 + 4 1/4 = 6 3/4

6 3/4 = 27/4

$54\div \frac{27}{4} = 54\times \frac{4}{27} = 2 \times 4 = 8$

So Naomi earned $8 per hour that she mows the lawn.

number from 1 to 99 is written on a card making a pack of 99 cards. What is the probability of randomly selecting a card where t

andriy [413]

Answer:

(19/99) = 0.192

Step-by-step explanation:

Numbers 1 to 99, that is 99 numbers (obtained through the equation for the nth term of an AP)

L = a + (n-1) d

L = nth term = 99

a = first term = 1

n = number of terms = ?

d = common difference = 1

99 = 1 + (n-1)1

n = 99

Sample space = 99

The numbers that include at least, a 1 are

1, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 31, 41, 51, 61, 71, 81, 91

19 numbers.

Probability of randomly selecting a card where the number contains at least one digit 1 from 1 to 99 = (19/99) = 0.192

Hope this Helps!!!
