LA = perimeter of base x height
Use Pythagorean theorem to find the base
4^2 + 6^2 = 52
Sq root of 52 is 7.2111...
4+6+7.2 = 17.2
17.2 x 8
137.6 is your answer
The answer would be 52.7.5
Answer:
largest area that can be enclosed = 8,000,000 m²
Step-by-step explanation:
Since it is a rectangle plot, the area is expressed as; A = xy, where x is length and y is width.
Because it is next to the river, he only needs to fence three sides, so amount of fencing; F = x + 2y.
Since we know the amount of fencing available is 8000m, we get:
8000 = x + 2y
solving for x, we have;
x = 8000 - 2y
substitute 8000 - 2y for x into the area equation to give;
A = (8000 - 2y)y distribute
A = -2y² + 8000y
Now, due to the negative sign next to 2, this will be a parabola which opens down, meaning that the point of maximum area will be at the vertex,
Thus; y = -b/2a = -8000/[2(-2)] = 2000
x = 8000 - 2(2000) = 4000
A = 4000(2000) = 8,000,000 m²
Conditional probablility P(A/B) = P(A and B) / P(B). Here, A is sum of two dice being greater than or equal to 9 and B is at least one of the dice showing 6. Number of ways two dice faces can sum up to 9 = (3, 6), (4, 5), (4, 6), (5, 4), (5, 5), (5, 6), (6, 3), (6, 4), (6, 5), (6, 6) = 10 ways. Number of ways that at least one of the dice must show 6 = (1, 6), (2, 6), (3, 6), (4, 6), (5, 6), (6, 6), (6, 5), (6, 4), (6, 3), (6, 2), (6, 1) = 11 ways. Number of ways of rolling a number greater than or equal to 9 and at least one of the dice showing 6 = (3, 6), (4, 6), (5, 6), (6, 3), (6, 4), (6, 5), (6, 6) = 7 ways. Probability of rolling a number greater than or equal to 9 given that at least one of the dice must show a 6 = 7 / 11
Answer:
The number of ways to select 37 people from 101 is, 5,397,234,129,638,871,133,346,507,775.
Step-by-step explanation:
In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.
The formula to compute the combinations of k items from n is given by the formula:
Compute the number of ways to select 37 people from 101 as follows:
Thus, the number of ways to select 37 people from 101 is, 5,397,234,129,638,871,133,346,507,775.
