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%.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
