Answer: 1.467
Step-by-step explanation:
Formula of Margin of Error for (n<30):-

Given : Sample size : n= 22
Level of confidence = 0.90
Significance level : 
By using the t-distribution table ,
Critical value : 
Standard deviation: 
Then, we have

Hence, the margin of error for the confidence interval for the population mean with a 90% confidence level =1.467
Answer:x=40
Step-by-step explanation:
To find this
8 times the reciprocal of a number
We get
Assume the number is x
8×1/x=2×1/10
8/x=2/10
8/x=1/5
Cross multiply
x=40

F(x) = a(x - h)³ + k
The parent graph is F(x) = x³
k - shifts the parent graph up k-units (or down if it is negative). This is also called a vertical shift.
h - shifts the parent graph to the right h-units (or left if it is negative). This is also called a horizontal shift.
a - stretches the parent graph vertically by a factor of "a"
Additonally, the coordinate (h, k) is the center/vertex of the graph.
