What is the formula for P^c(n,r)

Answers

Answer 1

Answer: P(n,r)= n! /(n-r)!
C(n,r)= n! / r! (n-r)!
P^c(n,r)= P raised to power C(n.r)? (If so, you know C(n,r) ; raise P to power C(n,r))
P(A/B) = P(A ∩ B) / P(B)

What is the radius of the circle given by the equation below? x2 - 2x + y2 - 2y - 98 = 0?

Answers

Complete the square for the given equation
x² - 2x + ____ + y² - 2y + _____ = 98
x² - 2x + (1) + y² - 2y + (1) = 98 + (1) + (1)
(x - 1)² + (x - 1)² = 100
(x - 1)² + (x - 1)² = 10²

Now the equation is in the form (x - h)² + (y - k)² = r²

Radius = 10

A recipe calls for 2 1/3 cups of honey. A second recipe calls for 3 3/4 cups of honey.Which expression should Cindi use to estimate how many cups of honey she needs in order to make sure she has enough for both recipes?

A.
2 1/2 + 4

B. 2 1/2 + 3

C. 2 + 4

D. 2 + 3 1/2

Answers

2 1/3 rounds to 2 1/2, and 3/4 rounds to 4.

Therefore we have:

2 1/2 + 4

The ordered pair (2, 36) is a solution for which equation(s)? Check all that apply. A. y = (x + 4)2
B. y = 7x2 + 2
C. y = (3x)2
D. y = 2x2

Answers

plug it into each equation and see if both sides are equal:
A. 36 = (2+4)^2 -> 36 = 36 works
B. 36 = 7(2)^2 +2 -> 36 = 30 doesn't work
C. 36 = (3(2))^2 -> 36 = 36 works
D. 36 = 2(2)^2 -> 36 = 8 doesn't work

BUILDING CODE A city has a building code that limits the height of buildings around the central park . The code says that all buildings must be less than 0.1x in height where x is the distance of the building from the center of the park and y is height in feet. Assume that the par center is located at 0. Write an inequality that represents the building code (1 pt)

Answers

The required inequality for the height of the building around the park should be y < 0.9x.

Given that,
A city has a building code that limits the height of buildings around the central park. The code says that all buildings must be less than 0.1x in height where x is the distance of the building from the center of the park and y is height in feet. Assume that the par center is located at 0.

What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
The height of all the buildings must be,
y < x - 0.1x
y < x(0.9)
y < 0.9x

Thus, the required inequality for the height of the building around the park should be y < 0.9x.
