Answer:
probability = 0.2517
Step-by-step explanation:
given data
boy kittens = 9
girl kittens = 6
choose kittens at random = 9
solution
total kitten are = 9 + 6 = 15
first we get here total no of probability that is
n(s) = 15 C 9
n(s) =
n(s) =5005
and
total way to chose 5 boy kittens is = 9 C 3
n(3) =
n(3) = 84
and
total way to chose 4 girl kittens is = 6 C 4
n(4) =
n(4) = 15
so
total way to chose 5 boy kittens and 4 girl kittens is
total way = 84 ×15 = 1260
so probability that the director chooses 5 boy kittens and 4 girl kittens is
probability =
probability = 0.2517
Answer:
10.6
Step-by-step explanation:
The amount of salt in one liter is 1.2 ounces, meaning to make one pound (16 oz) it would take 13 1/3 liters of water.
For 2.5 pounds, it would be 2.5*16, or 40-- 40 liters for 2.5 pounds of salt.
40 liters in (U.S.) gallons is 40/ (approximately) 3.785 , or 10.5680, 10.6
Answer:
The x pattern goes by adding 2 each time; the y pattern goes by adding 6 each time.
Slope formula: y/x
= 6/2
= 3
