Answer:
X = (J+M)/K
Step-by-step explanation:
Undo what has been done to the variable, in reverse order. The variable has been multiplied by K and M subtracted from the result. So, we first add M (to undo the subtraction), then we divide by K (to undo the multiplication).
KX = J +M . . . . . . M added to the given equation
X = (J + M)/K . . . . the result of that is then divided by K
___
Since these are all capital letters, we might assume they represent vectors and/or matrices. If so, the "divide by K" step needs to be "multiply on the left by K^-1, the matrix inverse of K."
Then your solution looks like
X = K⁻¹·(J + M)
Answer:
1/2
Step-by-step explanation:
Step one:
given data
sample space
1 blue slice,
2 red slices, and
3 yellow slices
sample size= 1+2+3= 6
Required:
The probability that the dial stops on a blue or red slice
1. The probability that the dial stops on a blue = 1/6
2. The probability that the dial stops on a red= 2/6= 1/3
Hence The probability that the dial stops on a blue or red= 1/6+1/3
= 1+2/6
=3/6
=1/2
Step one because they didn’t subtract 5 from the value -5/2.
