Answer:
0.000221
Step-by-step explanation:
Using the z score formula when a random number of samples is given =
z = (x-μ)/σ/√n, where
x is the raw score
μ is the population mean
σ is the population standard deviation = 7
n is random number of samples = 83
Note that:2.2 dollars = x-μ
z = 2.2/7/√8.3
z = 3.51402
Probability value from Z-Table:
P(x<27.7) = 0.99978
P(x>27.7) = 1 - P(x<27.7) = 0.00022069
Approximately = 0.000221
Hence, the probability that the sample mean would differ from the true mean by greater than 2.2 dollars if a sample of 83 5-gallon pails is randomly selected is 0.000221
Answer:
The total number of cups of coffee sold are 51 which can be expressed in base
as
.
Step-by-step explanation:
Considering the following information
cup =
cup
pints =
cups ∵
pint =
cups
quarts =
cups ∵
quart =
cups
So, total number of cups will be =
cups
Converting
to the base 
Divide
by
by repeatedly and observe remainder






Read and observe the remainder from top to bottom would yield
.
Therefore, the total number of cups of coffee sold are 51 which can be expressed in base

Answer:120
Step-by-step explanation:
calculate the sum of the negetive numbers 3x-40
=120
You can plot this by turning the fraction into a decimal. -1&1/3rds is -1.333... and 1/6ths is about .16, so then you can find these points on the number line. Also, the number line has 6 points equal one, so the points by those.
