Of 200 people surveyed, 80 percent own a cellular phone and 45 percent own a pager. if all 200 people surveyed own a cellular phone, or a pager, or both, what percent of those surveyed either do not own a cellular phone or do not own a pager?

75%

Step-by-step explanation:

In this problem , there are percentages and number types, converting all into percentages.

Now we need to calculate the percentage of people who don't have neither CP or Pager.

We are given 80% hold CP i.e. 20% does't have CP. Similarly for the pager.

We know that 20% doesn’t have CP and 55% doesn’t have a pager . 20% + 55% = 75% represents the percentage of people who dosesnt have neither CP or Pager .

Therefore the answer is 75%.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
