- <u>1. As a fraction: 9/50</u>
- <u>2. As a proportion: x/1 = 9/50</u>
- <u>3. As a percentage: 18%</u>

Explanation:
<u>1. As a fraction:</u>
Depart from the definition of probability: probability is the number of favoragle outcomes divided by the total number of possible outcomes:
- Probability = number of movie-goers who say they watched a movie on Netflix this week / number of movie-goers that saw a movie this week
<u>2. As a proportion:</u>
A proportion is the equality of two ratios. In this case you must set the ratio of people who say they watched it on Netflx, x, per every people who saw a movie this week, 1, equal to the ration 9 /50.
Hence, the proportion that shows the probability is:
Where x is the probability.
<u>3. As a percentage</u>
You just have to multiply the probability by 100:
Answer:
12.1
Step-by-step explanation:
In this question, we can use the pythagoras theorem to solve it.
the equation is 
= slant height.
= 12.1
$5.50. if he washes his dog every week, he is getting $6.60 automatically. So if we do simple math, 12.10-6.60= 5.50
Answer:
- recursive: a[1] = 7440; a[n+1] = a[n] -120
- explicit: a[n] = 7440 -120(n -1)
Step-by-step explanation:
The sequence of amounts in Jackson's account will be ...
7440, 7320, 7200, ...
with a first value (a1) of 7440 and a common difference (d) of -120.
The recursive formula for an arithmetic sequence is ...
a[1] = a1
a[n+1] = a[n] +d
For our sequence, the recursive formula is ...
a[1] = 7440
a[n+1] = a[n] -120
__
The explicit formula for an arithmetic sequence is ...
an = a1 +d(n -1)
For our sequence, the explicit formula is ...
a[n] = 7440 -120(n -1)
