Answer:
300 In
Step-by-step explanation:
1 foot = 12in
so, 25×12 =300
We let
a1 = first term
a2 = second term
a3 = third term
and so on
We are given with
a1 + a2 = 26
S5 (sum of five terms) = 35
The formula for the sum of terms is
Sn = (a1 + an) (n/2)
SO
35 = (a1 + a5) (5/2)
The formula for an arithmetic term is
an = a1 + d(n-1)
For
a2 = a1 + d
we know that
a1 + a2 = 26
Simply for a1, a2, and d. Then use the formula to get the other items asked.
Answer:
Step-by-step explanation:
To find the area of a circle with the radius, square the radius, or multiply it by itself. Then, multiply the squared radius by pi, or 3.14, to get the area. To find the area with the diameter, simply divide the diameter by 2, plug it into the radius formula, and solve as before.
Answer:
There is a 50.18% probability that they are of the same gender.
Step-by-step explanation:
We have these following percentages:
53% of the students are males.
47% of the students are females.
If two students from this college are selected at random, what is the probability that they are of the same gender?
The probability that each is male is 53%. So the probability of both being males is
The probability that each is female is 47%. So the probability of both being females is
The probabilty that both are the same gender is:
There is a 50.18% probability that they are of the same gender.
