Answer:
discount = 9
new price = 36
Step-by-step explanation:
The discount is the price times the discount percent
45 * 20%
Change to decimal form
45*.20
9
The new price is the original price minus the discount
45-9 = 36
Answer: 0.84134
Step-by-step explanation:
We need to find the z-score for the given information first since this will help us find the probability. The formula for this is
Z score = 
We have
66 inches (the raw score)
70 inches (the population mean)
= 4 inches (the standard deviation)
This gives
Z score =
= 
If you use a calculator, or a Z-score table then P(x > Z) is just P(Z > -1) which gives a probability of 0.84134.
Answer:
1024pi/3
Step-by-step explanation:
to find the volume of a sphere you use the equation 4/3*pi*r^3
4/3*pi*8^3
4/3*pi*512
2048/3 pi
This is the volume of the whole sphere but we only need half so we can just divide by 2.
(2048/3 pi)/2
1024/3 pi
Step-by-step explanation:
as the denominator (x+3) is in both you need only one denominator to be multiplied in first rational number .
<u>2</u><u>x</u><u> </u><u>(</u><u>x-2</u><u>)</u><u>. </u><u> </u><u> </u>+ <u>5</u><u>. </u><u> </u><u> </u><u> </u><u> </u><u> </u>
(x+3) (x-2). (x+3) (x-2)
<u>2</u><u>x</u><u>^</u><u>2</u><u>-</u><u>4</u><u>x</u><u> </u><u>+</u><u>5</u><u> </u>
<u>(</u>x+3) (x-2)
it's cannot be solved after that.
