The probability that the sum of the dice is 7 is 1/2 because there are only three combinations that result in the sum of 7: (1,6)(2,5) and (3,4). But there are 6 possible outcomes( this is if you don’t add reverse combinations such as 1,6 and 6,1) so the probability would be 3/6 or 1/2
∆volume = 4/3 *pi * (R^3 -r^3 )
= 4/3 *pi*((6)^3 -(3)^3)
= 252*pi
= 791.68 m^3
Answer:
1-8
Step-by-step explanation:
I was only able to finish one through eight The rest follow the same concept though
The lot costs 5000 dollars.
<u>Step-by-step explanation:</u>
The cost of a House and the lot = $40,000.
Let us assume the cost of lot as 'x'
Given that, The cost of the house is 7 times as much as the lot.
Therefore, The cost of the house= 7x
The cost of both the house and the lot= x + 7x
$40,000 = x + 7x
40,000 = 8x
x = 40,000/8
x = 5,000
The lot costs $5000.
First you would combine like terms on each side of the equation It would look like this... 4X+8= 4X-13
Then you would add 13 to both sides, the 13 on the right side of the equation would cancel out and the 8 would become 21. It would look like this... 4X+21=4x.
Now you would subtract 4X from both sides. The 4's Would cancel out which would leave you with 21=X
