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
Hence the probability that the household has only cell phones and has high-speed Internet is 0.408
<h3><u>Answer:</u></h3>
- The value of x is 17.
<u>We know that the lines are parallel because it is given that:</u>
- a ∥ b
<u>Now, let's form an equation.</u>
- => 2x + 5 + 8x + 5 = 180
<u>Let's solve!</u>
- => 10x + 10 = 180
- => 10x = 170
- => x = 17
Hence, the value of x is 17.
