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)
You would want to order 44 of the toys.
25 x 120% = 30 (2013)
30 x 120% = 36 (2014)
36 x 120% = 43.2, you can have .2 of a toy so you round up to the next whole number. So 44 (2015)
Hope this helps! :D
Answer:
frdg
Step-by-step explanation:
-9 degrees Celsius
because when the temp is negative it and it keeps going down, then the numbers basically get added and have a negative sign in front of it.
-3 +-2 +-4 = -9
Answer:
The recoil velocity of the gun is 
and is pointing in opposite direction to the velocity of the bullet.
Step-by-step explanation:
Use conservation of linear momentum, which states that the momentum of the bullet (product of the bullet's mass times its speed) should equal in absolute value the momentum of the recoiling gun (its mass times its recoil velocity).
We also write the mass of the bullet in the same units as the mass of the gun (for example kilograms). Mass of the bullet = 0.010 kg
In mathematical terms, we have:
