.50(150)+30=$105
8(32)+12 = $268
Answer:
Step-by-step explanation:
(17+11)/(-9-5)= 28/-14 = -2
answer is A
There are possible outcomes. At the least, you can draw (1, 2, 3) to get a sum of 6, and at most (5, 6, 7) for a sum of 18. Then the PMF is
That is, consider all the possible sums and their integer partitions. For example,
6 = 1 + 2 + 3
7 = 1 + 2 + 4
8 = 1 + 2 + 5 = 1 + 3 + 4
9 = 1 + 2 + 6 = 1 + 3 + 5 = 2 + 3 + 4
and so on.
Then the expected value is
We can find the variance via
Answer:
57
Step-by-step explanation:
Straight line value=180
Given Value=123
Value of ∆TKL
=180-123
=57(Ans)
Left-most section:
.. You can tell from the point (3, 9) that the only viable choice is selection D.
Center section:
.. When you extend the graph to the y-axis, you see the y-intercept is 10. The slope is negative, so selection B is appropriate.
Right section:
.. The line goes up 3 grid points for each 2 to the right, so the slope is 3/2. In point-slope form the equation of that line can be written as
.. y = (3/2)(x -6) +4 = (3/2)x -9 +4 = (3/2)x -5 = (3x -10)/2 . . . . . selection C
