Answer:
3/100
Step-by-step explanation:
convert these measurements into one unit, I am going to do decimals but you can sue fractions or percentages as well.
1/4 is 0.25
2/5 is 0.4
0.12 is 0.12
20% is 0.2
if you add all these up, it equals 0.97
1- 0.97= 0.03
you therefore have 0.03 of the money left over
this as a fraction is 3/100
Answer:
Kendall's shirt cost 18.20
Step-by-step explanation:
12.75+8.50=21.25
39.45-21.25=18.20
Answer:
Probability that the sample mean comprehensive strength exceeds 4985 psi is 0.99999.
Step-by-step explanation:
We are given that a random sample of n = 9 structural elements is tested for comprehensive strength. We know the true mean comprehensive strength μ = 5500 psi and the standard deviation is σ = 100 psi.
<u><em>Let </em></u>
<u><em> = sample mean comprehensive strength</em></u>
The z-score probability distribution for sample mean is given by;
Z =
~ N(0,1)
where,
= population mean comprehensive strength = 5500 psi
= standard deviation = 100 psi
The Z-score measures how many standard deviations the measure is away from the mean. After finding the Z-score, we look at the z-score table and find the p-value (area) associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.
Now, Probability that the sample mean comprehensive strength exceeds 4985 psi is given by = P(
> 4985 psi)
P(
> 4985 psi) = P(
>
) = P(Z > -15.45) = P(Z < 15.45)
= <u>0.99999</u>
<em>Since in the z table the highest critical value of x for which a probability area is given is x = 4.40 which is 0.99999, so we assume that our required probability will be equal to 0.99999.</em>
Answer:
The answer is -2/3.
