Given the range {2, 3, 9}, what is the domain for the relation y = x + 3?

balandron [24]

Roxy is multiplying 1/8 by 4/3

Vera_Pavlovna [14]

Answer:

1/6

Step-by-step explanation:

Make the denominators the same by finding the lcm(least common denominator). The least common demominator would be 24. So multiply both numbers in 1/8 by 3. This would eaqual 3/24. Multiply both numbersin 4/3 by 8. This would equal $\frac{3}{24} * \frac{32}{24}$ = $\frac{96}{576}$ . Simplify 96/576 by dividing both numbers by 96.

96 ÷ 96 = 1 576 ÷ 96 = 6 and that becomes 1/6.

Whilst shopping, the probability that Caroline buys fruit is 0.4. The probability that Caroline independently buys a CD is 0.2.

AleksandrR [38]

Answer:

probability that Caroline buy both CD and fruit = 0.52

Step-by-step explanation:

We have given that the probability of Caroline buys a fruit P = 0.4

So probability of Caroline does not buy the fruit = 1 - 0.4 = 0.6

Probability Caroline buys a CD P = 0.2

So probability of Caroline does not buy the CD = 1 - 0.2 = 0.8

So probability that Caroline does not buy either buy CD or fruit = 0.8×0.6=0.48

So probability that Caroline buy both CD and fruit =1-0.48 = 0.52
