Answer:
(3,2)
Step-by-step explanation:
I changed the first equation to x=y+1. Then I substituted the x in the second equation with y+1. So, I got 4(y+1)-3y=6. Then 4y+4-3y=6 turns into y=2. Then you replace y with 2 in the first equation. -x+2=-1. -x=-3 or x=3.
The volume of a cylinder is calculated from the product of its base area and the height. The base area is equal to the area of a circle which is expressed as A = πr^2 where r is one half the diameter and the radius of the circular base. So, the volume of a cylinder is equal to:
Volume of cylinder = π(r^2)h
r = D/2 = 3.5 in / 2 = 1.75 in
h = 12 in
Volume of cylinder = π((1.75 in)^2)( 12 in )
Volume of cylinder = 147π/4 in^3 or 115.45353 in^3
Therefore, the volume of the cylinder given its specifications would be equal to 115.45 cubic inches.
Answer:
Step-by-step explanation:
Use the formula to find the z-score, then go to the table that will give you the probability that the value is less than this z-score.
The probability that the value lies to the left of 1 on a standard bell curve is 84.1345%, or 84%, the third choice down.
