Jose is going to order wrenches for his hardware store. he can order four different types and the table shows the profit margin for each type in tens of dollars and the probability. which wrench should he order?

B

Step-by-step explanation:

The expected value of profit margin is the sum of the product of profit margin and probability.

Wrench A:

... 10×.05 +20×.6 +30×.2 +40×.15 = 0.5 +12 +6 +6 = 24.5

Wrench B:

... (20+40)×.3 +(30+50)×.2 = 18 +16 = 34

Wrench C:

... 15×.4 +30×.5 +(45+60)×.05 = 6 +15 +5.25 = 26.25

Wrench D:

... 5×.2 +10×.4 +15×.15 +20×.25 = 1 +4 +2.25 +5 = 12.25

___

Clearly, Wrench B has the greatest expected profit margin. That would be the one Jose should order if he's trying to maximize his profit.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
