Answer: x=1
Step-by-step explanation:
4x-12x=-1-7
-8x=-8
Expected value is $20.20
Step-by-step explanation:
Here, we want to calculate the expected value
What we have to do here is to multiply the probability by the payout value; after which we add all values
Thus, we have the payout value as;
1(0.12) + 4(0.2) +6(0.38) + 8(0.2) + 10(0.1)
= 0.12 + 0.8 + 2.28 + 1.6 + 1
Answer:
That is correct
Step-by-step explanation:
Answer:
The total cost of the bike is $180.
Step-by-step explanation:
Given that Juanita has saved 35% of the money for a bike.
Let the total cost of the bike = x
As she has saved $63 dollars which represents the 35% of the money for a bike.
In other words, 35% of the total cost is $63 dollars.
As the total cost = x
Thus,
35% of x = 63

Multiply both sides by 20

simplify

Divide both sides by 7

Simplify
$
Thus, the total cost of the bike is $180.
