Answer:
10
Step-by-step explanation:
8x+16+60=156
8x+76=156
8x=80
x=10
Answer:
let ratio be 3x,11xand13x
perimeter=298cm
3x+11x+13x=298
27x=298
x=298/27=11approax
shortest side=3×11=33
Step-by-step explanation:
you are right .
Answer:
4.43
Step-by-step explanation:
Given :The probability that the San Jose Sharks will win any given game is 0.3694 based on a 13-year win history of 382 wins out of 1,034 games played
To Find : What is the expected number of wins for the that upcoming month?
Solution :
The probability that the San Jose Sharks will win is 0.3694
Let X = number of games won
Total no. of games = 12
We are supposed to find the expected number of wins for the that upcoming month
So, expected number of wins = E(X)=XP(X)=
Hence the expected number of wins for the that upcoming month is 4.43

6(6a-1)
Answer:
x=1, y=1.
Step-by-step explanation:
From the second equation:
x = 8 - 7y, so substituting for x in the first equation:
3/8(8 - 7y) + 1/3y = 17/24
3 - 21/8 y + 1/3y = 17/24
1/3y - 21/8y = 17/24 - 3
Multiply through by 24:
8y - 21*3 y = 17 - 72
8y - 63y = -55
-55y = -55
y = 1.
And substituting for y in the second equation:
x + 7(1) = 8
x = 8 - 7
x = 1.
