Answer: (1.4964, 1.5126)
Step-by-step explanation:
We know that the confidence interval for population mean is given by :-

, where
= population standard deviation.
n= sample size
= Sample mean
As per given , we have
σ = 0.01 inches
n= 10

Also, the critical value for 99% confidence interval =
[From x-value table.]
[Significance level =1-0.99=0.01 and
is 2.576.]
Then, the 99% two-sided confidence interval on the mean hole diameter will be :-

Hence, the required confidence interval = (1.4964, 1.5126)
Y = 5x - 13 ----------- (1)
5x + 2y = 19 --------- (2)
Sub (1) into (2):
5x + 2(5x -13) = 19
5x + 10x - 26 = 19
15x = 19 + 26
15x = 45
x = 3 -------- sub back into (1)
y = 5(3) - 13
y = 15 - 13
y = 2
Ans: x = 3, y = 2
Answer:
a=2^2
b=3^5
c=4^3x5^2
d=7^2x9^4
Step-by-step explanation:
All you have to do is write the number that is already there and power it by number of times it is repeated.
If there are two different numbers in a question (like c and d) you should start with the smaller number and then follow with the larger on with a x/times symbol between them.
The answer I got was 0.18
