X f πxf
-1 2 -2
3 1 3
-1 -2 2
0 -3 0
total =3
mean (π)=πxf ÷n
= 3÷4
= 0.75 these is not answer I thank so
The next the sequence is 19,23,27. it increases by 4. John is wrong
Answer:
7
Step-by-step explanation:
When finding the x intercept you replace the y with 0 leaving only x=7
16.004 = (1 x 10) + (6 x 1) + (0/10) + (0/100) + (4/1000)
Hope this helps ;)
Answer:
0.0416
Step-by-step explanation:
Given :
Sample size, n = 300
Sample mean, x = 35.5
Population mean, m = 35
Standard deviation, s = 5
The test statistic :
Zstatistic = (x - m) / s/sqrt(n)
Zstatistic = (35.5 - 35) / 5/sqrt(300)
Zstatistic = 0.5 / 0.2886751
Zstatistic = 1.732
Using the p value calculator from Zstatistic :
One tailed P value at 95% confidence interval is : 0.0416
