Answer:
7
Step-by-step explanation:
Put them in L to G
1 6 6 7 7 7 16 18 18 22 22
and u see how many times 7 repeated den all numbers.
You can take it apart. There are a top and bottom (both the same) right triangle. So you can find the area of that by multiplying 8*6 and divide by two. Then multiply by two because there are 2 triangles.
You are left with three rectangular sides: One 10x10, one 10x6, and one 10x8.
So your whole equation looks like this: A = 2[(8*6)/2]+(10*10)+(10*6)+(10*8)
You would multiply 2.75 by 50, which is 137.5 miles
Answer:
The probability that both the students selected are of the same gender is 0.25.
Step-by-step explanation:
Let <em>X</em> = number of students selected of the same gender.
The probability of selecting a student of a particular gender is,
P (X) = <em>p</em> = 0.50.
The number of students selected is, <em>n</em> = 2.
The random variable follows a Binomial distribution.
The probability of a binomial distribution is computed using the formula:

Compute the probability that both the students selected are of the same gender as follows:
P (Both boys) = P (Both girls) = P (X = 2)

Thus, the probability that both the students selected are of the same gender is 0.25.
