Answer:
The answer is incorrect; the plus sign should be a minus sign (apex)
Step-by-step explanation:
The answer A.the solution is (5,-2) definitely works because 5+-2=3 and 5--2=7 not sure if there's infinite number of solutions tho
Ok so the first one is 225 miles but i can't do the graph
and i'm not great at math so give me a bit
Answer:
Step-by-step explanation:
The key here is knowing that the equation of the line that passes through these points is same
Thus having (6,14) and (0,0), the slope is as follows;
m = y2-y1/x2-x1 = 0-14/0-6 = -14/-6 = 7/3
Now we can use this slope here to get the value of y in the question
All we need to do is tie write the equation of the line for between the points (6,14) and (2,y)
That would be;
7/3 = y-14/1-6
7/3 = y-14/-5
cross multiply;
-35 = 3(y-14)
-35 = -3y + 42
-3y = -35-42
-3y= -77
y = -77/3
y = 77/3

- <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:
