Answer:
The probability that the two rats are from the first litter is 14.28%, and the probability that the two rats are from the second litter is 34.28%.
Step-by-step explanation:
Since a cage holds two litter of rats, and one litter comprises one female and five males, while the other litter comprises seven females and two males, and a random selection of two rats is done, to find the probability that the two rats are from the same litter the following calculation must be performed:
6/15 x 5/14 = 0.1428
9/15 x 8/14 = 0.3428
Therefore, the probability that the two rats are from the first litter is 14.28%, and the probability that the two rats are from the second litter is 34.28%.
Answer:
186
Step-by-step explanation:
PEMDAS
First do 46 x 8 = 368 then divide that by 2, which would be, 184. Then add 2 to 184 and you get 186. :)
Equilateral, because the sides are equal
Answer:
Total amount of books in the bookcase = 225 books
Step-by-step explanation:
Each shelf is to have 15 books
Therefore total amount of books in the bookcase = {9×15} + {6×15} = 225 books
Slope formula is :
y₂-y₁ / x₂-x₁
Our points are : (2, 6) & (-4, -6)
y₂ = -6 ; y₁ = 6 ; x₂ = -4 ; x₁ = 2
So, now that we have our points and values, we simply plug everything into our slope equation.
y₂-y₁/x₂-x₁
-6 - 6/-4 - 2
Simplify.
-12/-6
Simplify.
2
Our slope is 2
