You get the product by multiplying...in this case you want to double the product of j and 8 so:
2(8*j)
2(8j)
16j
Step-by-step explanation:
The cost increase is:
(4 - 3) / 3 × 100%

The answer is none of these.
Answer:
Step-by-step explanation:
2x - 5y = 10
2(-3.5) - 5y = 10
-7 - 5y = 10
+7 +7
-5y = 17
-5 -5
y = -3.4
The value of y is equal to A. -3.4.
To calculate expected value,
We can add up the probability of all possible events.
The 2 possible events are either winning $50 or losing the prize, which is $ - 50
Expected value =
50 x 40 % + (-50) x 60%
= $-10
So the answer is $-10
