Answer:
<h2>The second pyramid, placed in the middle, has a volume of 15 square units.</h2>Step-by-step explanation:
Givens
- The area of the bases is 15 square units.
- All of them have the same base.
The volum of a pyramid is defined as
Where is the are of the base and
is the height.
So, all of them have
The first pyramid has a height of 4, replacing this in the formula we have
The second pyramid has a height of 3
The third pyramid has a height of 12
Therefore, the second pyramid, placed in the middle, has a volume of 15 square units.

Answer:
μ = 0.919
The interpretation of this is that;on the average, an individual aged 15 years or older has been involved in 0.919 marriages.
Step-by-step explanation:
The expected value which is also called mean value is denoted by the symbol μ. It is defined as the sum of the product of each possibility x with it's probability P(x) as the formula;
μ = Σx.P(x) = (0 × 0.272) + (1 × 0.575) + (2 × 0.121) + (3 × 0.027) + (4 × 0.004) + (5 × 0.001)
μ = 0.919
Thus, the interpretation of this is that;on the average, an individual aged 15 years or older has been involved in 0.919 marriages.
Answer:
Step-by-step explanation:
Total Surface Area of cylinder = Lateral Surface Area + Area of both circle bases.
Lateral Surface Area = Circumference of Circle Height
Lateral Surface Area =
Area of one circle base:
Area of both circle bases:
Total Surface Area =
