Probability of choosing a black fly = 30/100 = 0.3

Probability of choosing a grey fly = 70/100 = 0.7

So, probability of choosing 2 grey flies = 0.7*0.7 = 0.49

Samuel plans to install a fence around the perimeter of his yard. His yard is shaped like a square and has an area of 40,000 squ
NISA [10]

Answer:

$450

Step-by-step explanation:

The area of the square is 40,000 square feet so the square's side length is 20 (√40,000).

The company charges $2.50 per foot, and the perimeter is 80 (20*4), so the  cost is $400 ($2.50 * 8).

Add on the $50 installation fee and the total cost is $450 ($400 + $50).

Find the h.c.f of {x}^{3} + {y}^{3} \: and \: \: {x}^{2} - xy + {y}^{2}x 3 +y 3 andx 2 −xy+y 2 ​
Ahat [919]

Factorize the sum of cubes:

x^3 + y^3 = (x+y) (x^2 - xy + y^2)

so x^2-xy+y^2 is a factor of x^3+y^3. Then the HCF is \boxed{x^2 - xy + y^2}.
