When looking at probabilities, two ideas are always true.
1) Any probability is more than 0.
2) The sum of all the probabilites is 1.
Idea #2 works here. (For example, think of how a die has six things and the probability of each is 1/6. So 1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 1.) Let G = the probability of grape, C = probability of cherry and O = the probability of orange. From Idea #2, G + C + O = 1. Since we know G and C, then
3/10 + 1/5 + O = 1.
3/10 + 2/10 + O = 1
5/10 + O = 1
O = 5/10
Thus, the probability of an orange jelly bean is 5/10 = 1/2.
Answer:
--- real windscreen
--- scale volume
Step-by-step explanation:
Given
--- scale factor
See attachment
Required
Complete the table
To get the windscreen (w) of the real car, we do the following computation
This gives:
Next, the volume (v) of the scale mode
We make use of the following computation
So, we have:
14,999(1+.o825)^4= 20,595. $429x48 months= 20,592
Interest rate 8 1/4%
Check 20592/14999= 1.37289
Log(1.37289)/ log(1.0825)= 3.99 years
Well, he made $100 off of drinks, and $135 off of ice cream bars.
Then to find his profit take $235 - $31.50 = $203.50
There's your answer! $203.50 was his profit.
