Answer:
Step-by-step explanation:
Let the three consecutive integers be x, x + 2 and x + 4
<u>So, the given condition is:</u>
x + x + 2 + x + 4 = 129
3x + 6 = 129
Subtract 6 to both sides
3x = 129 - 6
3x = 123
Divide 3 to both sides
x = 123/3
x = 41
<u>So, the integers are:</u>
x = 41
x + 2 = 41 + 2 = 43
x + 4 = 41 + 4 = 45

Answer:
0.0094.
Step-by-step explanation:
For the given experiment, let X be the lifetimes of parts manufactured from a certain aluminum alloy.
sample size =73
Sample mean = 784
Sample standard deviation = 120
Let µ represent the mean number of kilocycles to failure for parts of this type.
Null hypothesis, H0 : µ ≤ 750
Alternative hypothesis, H1 : µ > 750.
where,
is sample mean.
is population mean.
s is sample standard deviation.
n is the sample size.
It is a right tailed test because alternative hypothesis is µ > 750. So, P-value is the probability of observing a sample mean greater that 783 or the probability of P(z>2.35).
Therefore the P-value is 0.0094.
Answer:
x=105
Step-by-step explanation:
75+75+x+x=360
150+2x=360
2x=210
x=105
I hope this is correct and helps you!
