Answer:

C.) -7/5

Step-by-step explanation:

To subtract fractions, we need to have common denominators. So first, we will change -1 1/5 to -6/5.

Now we will change the denominator of both -6/5 and 1/2 to 10.

We now have:

5/10 and -12/10

5-12=-7

So the answer would be -7/5

If we want to use the number line, we would first find 5/10 (1/2) on the graph and count down (to simulate subtraction) 12 units since we are subtracting by 12. :))

If X and Y are any random variables with E(X) = 5, E(Y) = 6, E(XY) = 21, V(X) = 9 and V(Y) = 10, then the relationship between X
natka813 [3]

Answer:

We have a strong negative relationship between the variables.

Step-by-step explanation:

Given two random variables X and Y, it is possible to calculate the covariance as Cov(X, Y) = E(XY)-E(X)E(Y). We have E(X)=5, E(Y)=6 and E(XY)=21. Therefore Cov(X,Y)=21-(5)(6)=21-30=-9. On the other hand, we know that the correlation of X and Y is the number defined by Cov(X,Y)/\sqrt{Var(X)}\sqrt{Var(Y)} and because in this particular case we have V(X)=9 and V(Y)=10, we have -9/\sqrt{9}\sqrt{10} = -0.9487. Therefore, we have a strong negative relationship between the variables.

Find the greatest common factor of 18 and 35. <br>​
xxMikexx [17]

Answer:

1

Step-by-step explanation:

We need to find the factors of 18 and 35

Breaking into prime factors

18 = 2*9 = 2*3*3

35 = 5*7

There are no common factors so the greatest common factor is 1
