Answer:
120 On edge i got it right
Step-by-step explanation:
Answer: x=-1
Step-by-step explanation:
For a set of trials
![P_{desired}=\frac{desired}{total}](https://tex.z-dn.net/?f=P_%7Bdesired%7D%3D%5Cfrac%7Bdesired%7D%7Btotal%7D)
. In this case our desired out come is all multiples of 3: 3,6,9 and 12. The total number of outcomes can be found as 100 by adding up all the frequencies. Thus our experimental probability is
![P_{x=3n}=\frac{6+14+12+1}{100}=\frac{33}{100}=33\%](https://tex.z-dn.net/?f=P_%7Bx%3D3n%7D%3D%5Cfrac%7B6%2B14%2B12%2B1%7D%7B100%7D%3D%5Cfrac%7B33%7D%7B100%7D%3D33%5C%25)
.
Average speed = dist/time
v = (17/5) ÷ (7/8)
v = (17/5) x (8/7)
v = (17 x 8) ÷ (5 x 7)
v = 136 ÷ 35
v= 3 + (31/35)
v = 3 31/35
