$15.75 each can costs $1.75. So 1.75x9= 15.75
Answer:
Sample size is
Step-by-step explanation:
Given that,
Margin of error %
Confidence level %
Suppose, sample proportion
i.e.
We know that,
Margin of error
∴
squaring on both side,
∴
Hence, the sample size is,
Hence, the correct option is
Answer:
0.9985
Step-by-step explanation:
The population standard deviation is:
s² = 64
s = 8
The sample standard deviation is:
σ = s/√n
σ = 8/√39
σ = 1.28
The z-score is:
z = (x − μ) / σ
z = (128.2 − 132) / 1.28
z = -2.97
The probability is:
P(Z > -2.97) = 1 − P(Z < -2.97)
P(Z > -2.97) = 1 − 0.0015
P(Z > -2.97) = 0.9985
You have to set up a ratio between the owner's income and the total income so
<u>47</u> = <u>2176.10</u>
53 x
then cross multiply to slove for x
47x = 115333.30
then divide each side by 47
x = 2453.90
the company makes $ 2453.90
Calculate the probability of drawing 4 red balls and then 4 green balls as shown;
P(4R+4G)=(
)(
)(
)(
)(
)(
)(
)(
)
P(4R+4G)=0.00308 chance
The denominators are decreasing as the balls get taken out.
Hope I helped :)
