Answer:
The distribution of average life time is approximately normallyl distributed with mean 20 hours and standard deviation of 0.4743 hours
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem

The distribution of average life time is approximately normallyl distributed with mean 20 hours and standard deviation of 0.4743 hours
Answer:
{x,y} = {-2,2}
Step-by-step explanation:
Solve equation [2] for the variable y
7y = 7x + 28
y = x + 4
Plug this in for variable y in equation [1]
-8x + 4•(x +4) = 24
-4x = 8
Solve equation [1] for the variable x
4x = - 8
x = - 2
By now we know this much :
x = -2
y = x+4
Use the x value to solve for y
y = (-2)+4 = 2
Solution :
{x,y} = {-2,2}
and this intersects at only one point so your answer is A
So in order for us to know which angle is the smallest and which one is the largest, take note that the largest angle is the opposite of the longest side, and the smallest angle is the opposite of the shortest side. So base on the given figure above, the smallest angle would be angle p, then next is angle q and the largest, therefore would be angle r. Hope this answer helps. So it is p,q,r.
Answer:
the answer is 11 quarters and 20 pennies
Step-by-step explanation: because it said 9 more pennies than quarters so 11 x .25 = $1.75 + $0.20 = $2.95
