Get them to have the same number on the bottom by finding the lowest common number when multiplying which would be multiplying them by each other by you also have to multiply the top number so for 1/5 multiply 1 & 5 by 3 and you get 3/15 then the same for 1/3 but multiply by 5 so it'll be 5/15 add them and you get 8/15 so you have 7/15 left.
Answer:
And we can find this probability with the complement rule and with the normal standard table and we got:
Step-by-step explanation:
Let X the random variable that represent the patient recovery time of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And we can solve this problem using the z score formula given by:
And using this formula we got:
And we can find this probability with the complement rule and with the normal standard table and we got:
Answer:
? = 3x
Step-by-step explanation:
2(? + 5) = 6x + 10
You must plug in a number that will get the same value on both sides of the equal sign.
2*5 = 10
2*? = 6x
6x/2 = 3x
Answer:
the first one
Step-by-step explanation:
if you simplify 10/2 it is 5. there is already a 5 as an x value, so that means this isn't a function.
