Answer:
50 times.
Step-by-step explanation:
When the 2 number cubes are rolled once:
The possible outcomes for a total of 7 are:
1 and 6
6 and 1
2 and 5
5 and 2
3 and 4
4 and 3
= 6 outcomes.
The total of all possible outcomes = 6 * 6 = 36.
So Prob( total of 7 in one throw of teh 2 cubes) = 6/36 = 1/6.
For 300 throws you would expect the total of 7 to occur
1/6 * 300 = 50.
Answer:
0.388889 yd
Step-by-step explanation:
Get all the x terms on one side, and the w on the other.
Add 37x on both sides to get 56x+rx=w.
Use the distributive property backwards to get x(56+r)=w.
Divide by 56+r on both sides to get x=w/(56+r)
Answer:
Negative
Step-by-step explanation:
When you multiply a negative number by a positive number then the product is always negative.
Answer:
The exact charge per cubic foot of water usage is 4 Cents.
Step-by-step explanation:
Let the per cubic foot charge be $ 'x' and the fixed charge be $ 'y'.
A household using 1100 cubic feet was billed $ 114.
Therefore, we get the equation,
.......( A )
And other household 1500 cubic feet was billed $ 130.
Therefore, we get the equation,
......( B ).
Now, we subtract equation A from equation B.
.....( B )
......( A )

So, we get,
.
Therefore,
Cents.
So, the exact charge per cubic foot is 4 Cents.
