Answer: 0.4667
Step-by-step explanation:
According to 68–95–99.7 rule , About 99.7% of all data values lies with in 3 standard deviations from population mean (
).
Here , margin of error = 3s , where s is standard deviation.
As per given , we have want our sample mean
to estimate μ μ with an error of no more than 1.4 point in either direction.
If 99.7% of all samples give an
within 1.4 , it means that

Divide boths ides by 3 , we get

Hence, So
must have 0.4667 as standard deviation so that 99.7 % 99.7% of all samples give an
within 1.4 point of μ .
Answer:
job A
Step-by-step explanation:
job B pays $34560 yearly because every since it pays $720 weekly and there are 48 weeks in a year $720 multiplied by 48 is $34560. Job C pays $37440 because there are 12 months in a year and semimonthly means two times per month so 12 times 2 times $1560 give you $37440. Therefore job A pays the most amount per year.
Answer:
7
Step-by-step explanation:
plug in 3 where ever there is x
so
(4(3)+2)-7
use PEMDAS to solve from left to right
P: Parenthesis
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
so we got p so we do that first
(4(3)+2) --> 4 × 3 = 12 (Multiplication first like in PEMDAS)
(12+2) = 14
so then in the equation you are left with
(14)-7 = 7
answer is 7
4,4,4,5,5,5,6,6,7,8,8,8,9,10,10,10,10
It is the number 7.
