You have 2 dollars and 80 cents
The choice A will be the correct choice dealing with proportion
Answer:
B. The statement does not make sense because 1 yen is worth approximately $0.0087
Step-by-step explanation:
Since $1 = ¥115 you can substitute ¥115 for $1 in the statement to see if it makes sense. (You can always substitute equals.)
Then you get ...
... so 1 yen is worth more than 115 yen. -- <em>a statement clearly false</em>
Answer:
0.9251
Step-by-step explanation:
z = (x-μ)/σ/√n where
x is the raw score
μ is the population mean
σ is the population standard deviation.
n is the random number of samples
(x-μ) = 0.83 months
σ = 7
n = 147
z = 0.83/7/√147
z = 0.83/0.5773502692
z = 1.43760217026
z ≈ 1.44
Determining the probability of the z score from the z table.
P(x<Z) = 0.92507
Approximately to 4 decimal places = 0.9251
