Answer:
V = 75 pi m^3
or approximately
V =235.5 m^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
where r is the radius and h is the height
V = pi * 5^2 *3
V = 75 pi m^3
If we use 3.14 as an approximation for pi
V =235.5 m^3
Answer:
Dear math why dont you grow up and solve your own problems
Step-by-step explanation:
Answer:
positive
Step-by-step explanation:
A positive slope means the value on the line increases going from left to right.
A negative slope means to value decreases from left to right.
A slope of zero means the value does not change at all, just a horizontal line.
An undefined slope is a vertical line.
Total marbles in the bag = 15
Red marbles in the bag = 5
Probability of picking a red marble the first time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble the second time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble the third time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble the fourth time = 5/15 .
If you put it back, then everything goes back to the beginning.

Probability of picking a red marble the 20th time = 5/15 .
If you put it back, then everything goes back to the beginning.

Probability of picking a red marble the ' Nth ' time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble ' N ' times in a row = (5/15)^N.
Probability of picking a red marble 3 times in a row = (5/15) (5/15) (5/15).
Probability of picking a red marble 2 times in a row = (5/15) x (5/15)
= (25/225) = 1/9
= 11.1% (rounded).
A / b = -2
Take note:
to have a quotient with at negative sign, both a & b must have opposites signs. a can be a positive number while b is a negative number or vice versa. If both a and b have the same sign, its quotient will be a positive number.
Let us disregard the sign.
To arrive at the answer of 2, a must be twice the amount of b. meaning a = 2b.
For example: look for a if b is equal to 2. a = 2(2) ; a = 4.
a / b = 2
4 / 2 = 2
2 = 2
Now, we consider the sign of both numbers. a can be 4 while b can be -2 OR vice versa.
a / b = -2
4 / -2 = -2 or -4 / 2 = -2
