After the plus sign ur equations gets a little difficult to read are there any parentheses
I believe that it is 8.87 feet. If that is the answer you are looking for.
Answer:
3/26 students or 11%
Step-by-step explanation:
probability dependant formula:P(A∪B)=P(A)+P(B)−P(A∩B)
P(a)= basketball
P(b)=baseball
so
P(AUB)=P(A)+P(B)-P(A∩B)= 18/26+5/26-20/26=3/26
3/26 or 11%
OR you could solve this by adding all the sport/non sport #'s 18+5+6=29 and subtract 26 from 29
29-26=3
hence 3/26 students would randomly play basketball or baseball
Hope this Helps!
Answer:
2 / (1/5)
Step-by-step explanation:
(Is that what you meant?)
Let r = usual driving rate
let t = usual driving time
We need to figure out t
The distance she covers in her usual time at her usual rate is r*t
The distance she covers in her new time at her new rate is:
(1+t)*((2/3)r)
Set this equal to each other and solve for t.
rt = (2/3)r + (2/3)rt
(1/3)rt = (2/3)r
(1/3)t = (2/3)
t = 2
So her usual time is 2 hours. (There's probably a faster way to do this)
