I think it's A because it is making bigger in the middle of more than the others
Answer:
And replacing the value obtained we got:
And if we solve for a we got
Step-by-step explanation:
Let X the random variable that represent the average home prices of a population, and for this case we know the distribution for X is given by:
Where and
For this part we want to find a value a, such that we satisfy this condition:
(a)
(b)
We want to find a value who accumulate 0.10 of the area on the left and 0.90 of the area on the right of the normal standard distributon and for this case it's z=-1.282
And using the distribution for the sample mean we can do this:
And replacing the value obtained we got:
And if we solve for a we got
Answer:
Okay so we need to simplify, which means to find the smallest possible number but for it to be the same.
Step-by-step explanation:
An example is: 12/20 = 3/4
It equals that because 12/20 can be rewritten as 3/4.
Another example is: 24/30 = 4/6
It equals that because 4 can be added into 24 6 times, so it would be written as 4/6.
Another example is: 15/45= 5/15
It equals that because 5 can be fitted into 15 3 times, so the answer is 5/15.
I hope this helps
Answer:
1/2
Step-by-step explanation:
9/10 - 4/10 = (9-4) / 10 = 5/10 = 1/2
Answer:92.5
Step-by-step explanation:
The middle numbers are 92 and 93 and then you add 92+93=185 and 185/2=92.5
