You have a base that is 8x8 and the slant height of the triangle is 22.
This is the formula, L=1/2Ph
H = 22 Meters
1. P=2L+2W -> 2(8)+2(8) = 32 meters
2. L= 1/2(32)(22) = 352 meters squared :)
Geometry is a subject with a lot of formals and can be studied for years. What specific kind of formulas would you like?
Answer:
7
Step-by-step explanation:
This is a Poisson distribution problem with the formula;
P(x;μ) = (e^(-μ)) × (μ^(x))/x!
We are told that the grocer sells three of a certain article per week. Thus;
μ = 3
Now, we want to find out How many of these should he have in stock so that the chance of his running out within a week is less than 0.01.
This means;
P(X > k) < 0.01
This can be rewritten as;
P(X ≤ k) < 0.99
Let's try x = 8
P(8;3) = (e^(-3)) × (3^(8))/8!
P(8;3) = 0.008
But; P(X ≤ 8) = 1 - 0.008 = 0.992
This is more than 0.99 and thus is not the answer
Let's try x = 7
P(7;3) = (e^(-3)) × (3^(7))/7!
P(7;3) = 0.022
But; P(X ≤ 7) = 1 - 0.022 = 0.978
Thus is less than 0.99.
Thus, stock should be 7

Answer: 36 cm</h2>
Step-by-step explanation: 4 times 2.4 gives you 9.6. So you do the same to the 15. 15 times 2.4 = 36.375, or just 36.
F(x) is basically the output or y of whatever x is
