Atv show, lindsay and tobias, recently had a share of 20, meaning that among the tv sets in use, 20% were tuned to that show. assume that an advertiser wants to verify that 20% share value by conducting its own survey, and a pilot survey begins with 15 households having tv sets in use at the time of a lindsay and tobias broadcat.

(a) find the probability that none of the households are tuned to lindsay and tobias.
(b) find the probability that at least one household is tuned to lindsay and tobias.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

you bought 31 v bucks

step-by-step explanation:

25+6=31

5

step-by-step explanation:

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
