Answer:
29.27% probability that it takes Ariana between 58 and 70 seconds to do a math problem
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d, d being greater than c, is given by the following formula:
![P(c \leq X \leq d) = \frac{d-c}{b-a}](https://tex.z-dn.net/?f=P%28c%20%5Cleq%20X%20%5Cleq%20d%29%20%3D%20%5Cfrac%7Bd-c%7D%7Bb-a%7D)
Uniformly distributed between 38 seconds and 79 seconds.
This means that ![a = 38, b = 79](https://tex.z-dn.net/?f=a%20%3D%2038%2C%20b%20%3D%2079)
What is the probability that it takes Ariana between 58 and 70 seconds to do a math problem
![c = 58, d = 70](https://tex.z-dn.net/?f=c%20%3D%2058%2C%20d%20%3D%2070)
![P(58 \leq X \leq 70) = \frac{70 - 58}{79 - 38} = 0.2927](https://tex.z-dn.net/?f=P%2858%20%5Cleq%20X%20%5Cleq%2070%29%20%3D%20%5Cfrac%7B70%20-%2058%7D%7B79%20-%2038%7D%20%3D%200.2927)
29.27% probability that it takes Ariana between 58 and 70 seconds to do a math problem
Answer:
2
Step-by-step explanation:
The slope is the rise over the run. 2 simple coordinates I can see is (6,2) and (7,4). I usually like to visualize it instead of actually solving it mathematically. So, we can start at (6,2). The point (6,2) goes up 2 and 1 to the right in order to get (7,4.) So since the slope is rise over run ( y/x) it would be 2/1 because we went 2 up the y axis and 1 to the right of the x axis. So 2/1 is 2. Therefore, 2 is the answer. I'm sorry if my explaining isn't the best... I hope this helps though!!
I think the answer is 30, because if 134 +16 is 5 times the number of books Beezus reads, than just divide by 4 for the answer of 30
