D. 16 people. Just count all numbers until 88.
The sum is 12x3+18x2-10x+8
Answer: <u>16.</u> 21ft
<u>17.</u> 116.67mi or ≈117mi
<u>18.</u> 1,377,795in or 3,499.993m or ≈3500m
How we would calculate each of these: For number 16, you would set up a proportion of 1/3=7/x and then simplify this to 1x=21 which results in you dividing 1 from both sides of the equation and getting 21 as x, or the amount of feet. For number 17, you would do the same thing except with the different numbers. You set up another proportion. 3/50=7/x and then simplify to 3x=350. Divide the 3 on both sides and you get x=116.67mi to which you can round to 117mi if you like. For number 18, you must convert the 3.5 kilometers to inches and get 1,377,795in and then you can convert those inches into meters which would be 3,499.993m or you can round it to around 3500m.
It should be the same, 25%. Let's say Josh makes $4,000 a year, and Jeff makes $5,000. Jeff makes 25% more than Josh, and Josh makes 25% less than Jeff. Hope this helped.
The probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.
<h3>What is probability?</h3>
Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event. The probability of an event can not be more than the number 1.
John is playing a game of darts. In this game of dart,
- The probability that he throws a dart into the center of the dart board (the Bull’s eye) is 1/10.
- The probability that he throws the dart into the 10-point ring is 3/10.
The probability that he either hits a Bull’s eye or scores 10 points is equal to the sum of the probability he hits the bull's eye and the probability that he throws the dart into the 10-points ring.
Let, the probability that he either hits a Bull’s eye or scores 10 points is P. Thus,

Hence, the probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.
