4.20. According to a report released by the National Center for Health Statistics, 51% of U. S. households has only cell phones (no land line). According to the FCC, nearly 70% of the U. S. households have high-speed Internet. Suppose of the U. S. households having only cell phones, 80% have high-speed Internet. A U. S household is randomly selected. a. What is the probability that the household has only cell phones and has high-speed Internet

The probability that the household has only cell phones and has high-speed Internet is 0.408

Step-by-step explanation:

Let A be the event that represents U.S. households has only cell phones

Let B be the event that represents U.S. households have high-speed Internet.

We are given that 51% of U.S. households has only cell phones

P(A)=0.51

We are given that 70% of the U.S. households have high-speed Internet.

P(B)=0.7

We are given that U.S. households having only cell phones, 80% have high-speed Internet. A U.S household is randomly selected.

P(B|A)=0.8

Hence the probability that the household has only cell phones and has high-speed Internet is 0.408

not solvable

step-by-step explanation:

we need more information, or at least an

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
