Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given as:

Given that μ = $72,641 and σ = $30,000.
a) x > $100000

P(x > 100000) = P(z > 0.91) = 1 - 0.8186 = 0.1814
b) n = 5
x > $100000

P(x > 100000) = P(z > 2.04) = 1 - 0.9793 = 0.0207
c) n = 10
x > $100000

P(x > 100000) = P(z > 2.88) = 1 - 0.9980 = 0.002

Answer:
35,136 ml
Step-by-step explanation:
The tank holds 55,000ml. Mr. Clark poured some gas into 3 container, and at the end there the tank had 19,864. To find how much gas was poured out of the tank it is the same as asking how much gas he poured in the 3 containers, all together. We have to find the difference, subtraction:
55,000 - 19,864 = 35,136ml were poured in the 3 containers or amount of gas poured out of the tank.
1 mile * (1 hr / 4 mile) = 1/4 hr
1/4 hr = 15 min
Answer:
7/8 estimated would be about 1 and 6/11 is almost a half so it would be estimated 1/2 so 1 - 1/2 = 1/2
