Answer: D
Step-by-step explanation: Add it all up
Answer:
False
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
Sample of 121, which is higher than 30.
So we do not need to know anything about the shape of the distribution in order to make an interval estimate of the mean of all the account balances.
So the answer is False
Answer:
the three options i chose:
A. n and k are on plane A and s
C. p is the inteersection of n and g
D. those 3 lines are noncollinear
Answer:
<h2>x = 29°</h2>
Step-by-step explanation:
From the question the angles lie on a straight line which means that the sum of their angles add up to 180°
Since angles on a straight line add up to 180°
To find the value of x add up all the angles and equate it to 180 to find x
That's
x + 4 + 147 = 180
x + 151 = 180
x = 180 - 151
We have the final answer as
<h3>x = 29°</h3>
Hope this helps you
6x^3+13x^2+16 is the result.
