The probability of Julia picking 49 is 1/100 ( one number out of 100)
The probability of Shelly picking 49 is also 1/100 ( one number out of 100)
The probability of both picking the same number is
1/100 x 1/100 = 2/100 = 1/50 = 0.02 = 2%
A^2+b^2=c^2
Change the equation to suit the problem
c^2-a^2=x^2
5^2-4^2=x^2
25-16=x^2
9=x^2
Square root
3=x
The value of x is 3
Answer:
s₁ = 2 m/s
Step-by-step explanation:
given,
distance between Melissa and friend = 3 mile
walking speed = s₁
bike speed = s₂
total time of the trip = 2 hour
given,
s₂ = s₁ + 4
2(s₁ +4)s₁ = 3 (s₁ + s₁ + 4)
2 s₁² + 8 s₁ = 6 s₁ + 12
s₁² + s₁ - 6 = 0
s₁² + 3 s₁ - 2 s₁ - 6 = 0
(s₁ + 3) (s₁ -2) = 0
s₁ = -3 , 2
s₁ = 2 m/s
walking speed of the Melissa is s₁ = 2 m/s
I think the answer is D. The median is (90=78)/2 = 84
