The probability of not drawing a red marble is 7/10
The probability of drawing a red marble is 3/10
=======================================================
Explanation:
We have 3 red marbles out of 5+2+3 = 10 total. Therefore, the probability of selecting a red marble is 3/10.
The probability of not selecting a red marble is 7/10 because 3/10+7/10 = 1. Put another way, we have 7 marbles that aren't red (the 5 blue and 2 black ones) out of 10 total.
Answer: 890.12 cm^3
Step-by-step explanation:
The formula for the volume of a cylinder is

V=628.3185307 cm^3
or simply
V=628.32 cm^3
Since, you know the radius of the hemisphere on top, you also know the radius since the height of the hemisphere is the same as it is wide.
Next, the formula for the volume of a sphere is

so the volume of a hemisphere is half of that or:

V= 261.7993878 cm^3
or simply
V=261.80 cm^3
Finally, you add both of the volumes together to get
V= 890.1179185 cm^3
or simply
V=890.12 cm^3
Answer:
5x + 15
Step-by-step explanation:

(x + 3)5
= (x * 5) + (3 * 5)
= 5x + 15
