Sergeu [11.5K]

Answer:

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

$\frac{P(A\capB)}{P(A)}=0.8\\P(A\capB)=0.8 \times P(A)\\P(A\capB)=0.8 \times 0.51\\P(A\capB)=0.408$

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

Two less than thrice a number is 2 more than two third of

harkovskaia [24]

Step-by-step explanation:

Let the two numbers be x and y.

$\therefore \: 3x - 2 = \frac{2}{3} y + 2 \\ \\ \therefore \: 3x - \frac{2}{3} y = 2 + 2\\ \\ \therefore \: 3x - \frac{2}{3} y = 4 \\ \\ \therefore \: 9x - 2y = 12$

What is the product of (x+1) and (2x^2+3x-1)?

Assoli18 [71]

(x + 1)(2x^2 + 3x - 1) : Can be solved in multiple ways but easiest for me :P

x (2x^2 + 3x - 1) + 1(2x^2 + 3x - 1)

(2x^3 + 3x^2 - x) + (2x^2 + 3x - 1)

2x^3 + 5x^2 + 2x - 1
