Answer:
a) P=0.019
b) P=0.263
c) P=0.794
Step-by-step explanation:
We assume that the poll gives the population's proportion of respondents said that their jobs were sometimes or always stressful (p=0.8).
Then, a sample of size n=190 is taken.
The sample mean is:

The sample standard deviation is:

The probability that 140 or fewer workers find their jobs stressful is:

Note: a correction for continuity is applied.
The probability that more than 155 workers find their jobs stressful is

The probability that the number of workers who find their jobs stressful is between 145 and 158 inclusive is:

A. length = meter = m (base)
b. volume = cubic meter = m³ (derived)
c. mass = kilogram = kg (base)
d. temperature = kelvin = K (base)
Base
For example, in 2^3, 3 is the exponent and 2 is the base. The exponent, in this case 3, indicated how many times 2 is used as a factor. In expanded form, 2^3 equals 2*2*2=8.
Answer:
92.18 feet
Step-by-step explanation:
t(n)=125(.97)^x
t(10)=124(.97)^10
Sequence cant have partial or discrete bounce
The answer is 22,440......4 miles is 21,120 feet....1/4 of a mile is 1,320 feet.... so when you add em up you get 22,440 feet
