Answer:
0.5
Step-by-step explanation:
P(event) = number of times event occurs/ total number of trials
Hi, You are the person I answered last time!
P(event) = 8/16
8/16 simplified is equaled to 1/2.
1/2 is equaled to 0.5
Again, I'm pretty sure this is right because it says experimental probability... I hope this helps!
Low August: 9 C or 9.4 C if you need specifics

Answer: -1 so -1x
Step-by-step explanation:
You use the y1-y2/x1-x2 formula. so 9-7 is 2 and 5-7 is -2 you you have 2/-2 that simplifes to be -1
Answer:
So, this triangle PQR can be broken into two right triangles, PNQ and PNR, with legs PQ = 39, PN =15, and QN = ? and PR = 17, PN = 15, and NR =? respectively.
Let's solve for what is easier first:
Since we know that 5-15-17 is a Pythagorean triplet, we can infer that NR is 5....like I said earlier, it is a right triangle, so this guess holds true.
Here comes the interesting part:
Now, we have one part of QR, which is QN.
The other part can be solved by using the Pythagorean theorem.
It is (39^2-15^2)^(1/2)..which gives you 36, the square root of 1296, which happens to be the difference between the squares of 15 and 39.
SO, QR = QN + NR
5+36 = 41
QR = 41.
Hope this helps!
