Do you want to solve for x and y?
What is the objective?
Answer:
3x-10=x+4
Step-by-step explanation:
Answer:
Q= 90
Step-by-step explanation:
To do this problem you need to get q by itself and to do that you would move the 18 over
When you move the 18 over however you need to multiply and you will get 90
When ever you want to get a variable by itself always remember to switch the sign so if it was positive then switch it to negative and vice versa. It will also apply to multiplication and division just like this one
Answer:
Step-by-step explanation:
factors for
40=1,2,4,5,8,10,20,40
41=1,41 prime
3526=1,2,41,43,82,86,1763,3526
1001=1,7,11,13,77,91,143,1001
Solution: We are given:
μ=3.1,σ=0.5,n=50
We have to find P(Mean <2.9)
We need to first find the z score
z= (xbar-μ)/(σ/sqrt(n))
=(2.9-3.1)/(0.5/sqrt(50))
=(-0.2)/0.0707
=-2.83
Now we have to find P(z<-2.83)
Using the standard normal table, we have:
P(z<-2.83)=0.0023
Therefore the probability of the sample mean being less the 2.9 inches is 0.0023
