Answer:
A, B and E could not be probabilities
Step-by-step explanation:
By definition, <u>a probability could be any number between 0 and 1. </u>So a probability P would be 0≤P≤1. In percentages, 0% ≤ P ≤ 100%
Considering this we would have that:
A) 110% could not be a probability because it's larger than 100%
B) 5.42 could not be a probability because it's larger than 1.
C) 0.001 could be a probability because it's larger than 0 and smaller than 1 (It doesn't matter how small it is)
D) 0.58 could be a probability because it's between 0 and 1.
E) -120% could not be a probability because it's smaller than zero. (it's a negative number)
Thus, A), B) and E) could not be probabilities.
Answer:
432π cm² or 1356.48 cm²
Step-by-step explanation:
The area of a circle is πr²
The area of the disks are 144π and 576π.
576π-144π = 432π
432π ≈ 1356.48 cm²
<span>The first step in finding the surface area of a cone is to measure the radius of the circle part of the cone. The next step is to find the area of the circle, or base. The area of a circle is 3.14 times the radius squared (<span>πr2</span><span>). Now, you will need to find the area of the cone itself. In order to do this, you must measure the side (slant height) of the cone. Make sure you use the same form of measurement as the radius.
You can now use the measurement of the side to find the area of the cone. The formula for the area of a cone is 3.14 times the radius times the side (</span>πrl<span>).
So the surface area of the cone equals the area of the circle plus the area of the cone and the final formula is given by:</span>
<span>SA = πr2<span> + πrl</span></span><span><span>

Answer:
n=25% or 0.25
Step-by-step explanation:
865= 580(n%)+ 6(120)
865= 580 (n%) +720
865-720= 145
145= 580(n%)
divide both by 580, you get 0.25=n%
Answer:
3y-15
Step-by-step explanation:
(y-7)3=3y-21
3y-21+6=3y-15
