When dividing fractions these are the steps you will take:
1. The first number in the expression stays the same. If it is a whole number then you may just place a one in the denominator and keep the numerator as the whole number like so:
÷
2. Change the division sign into a multiplication sign
×
3. Take the reciprocal (switch the places of numerator and denominator) of the second number in the expression
×
4. Multiply across
^^^This can be further simplified:
4

Answer:
Distance of the trail from the start to the end is miles
Step-by-step explanation:
Distance from the start of a trail to the bird lookout point= miles
Distance from the bird lookout point to the end of the trail = miles
We want to find the difference of the trail from the start to the end, that is, how far is the starting point from the end point.
The distance between the start and end points
miles
Answer:
(b) Expected number of male kitten E(x) = 1
(c) Standard deviation is ±.
Step-by-step explanation:
Given that,
Number of kittens in a group are 10. Out of these 5 are female.
To find:- (a) create a probability model of male kitten chosen.
So, total number of kitten = 10
number of female kitten = 5
then, Number of male kitten =
Now total number of ways to choosing two kittens from group of 10 =
=
=
for choosing (i) No male P(x=0) = P(Two female) =
=
(ii) 1 male P(x=1) = P(1 male and 1 female) = =
=
(iii) 2 male P(x=2)= P(2 male) = =
0 1 2
P(X=)
(b) what is expected number of male kittens chosen ?
Expected number of male kitten E(x) =
=
(c) what is standard deviation ?
No,
=
= ±
