Answer:
5/18
Step-by-step explanation:
There are two ways this can happen: you roll a 3 on the first cube and not a 3 on the second cube, or you roll not a 3 on the first cube and 3 on the second cube.
P = (1/6)(5/6) + (5/6)(1/6)
P = 5/36 + 5/36
P = 10/36
P = 5/18
This equation does not have any zeros. Use the formula of (b*b)-4(a)(c).
Answer:
18
Step-by-step explanation:
In the linear regression equation y=a+bx, slope coefficient b represents average unit increases in y variable due to unit increase in x variable.
In the given equation ŷ = 84 + 18x, b=18 represents average unit increases in gas used due to unit increase in degree day.
Hence,on average, gas used increase by 18 for each additional degree-day.
We know that area of square is given by the formula , a^2(side square)
Given area is 9m sq
=> a^2 = 9 m sq
=> a = 3 m
So length of a side is 3m
