$38.46
work-
25.64/4 =6.41
6.41*6=38.46
so you will need a total of $38.46 to buy 6 books.
hope this helped!
Answer:
0.0326 = 3.26% probability that she is a student.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Woman developer
Event B: Student
Probability that the developer is a woman:
7.4% of 25.8%(students).
76.4% of 100 - 25.8 = 74.2%(not students). So

Student and woman developer.
7.4% of 25.8%(students), so

If we encounter a woman developer, what is the probability that she is a student

0.0326 = 3.26% probability that she is a student.
Since it's a square, the sides are all the same. This is going to be the equation.
S²=196
14×14=196
The length of one side is 14.
BD = AC/2
4x+2 = (5x+13)/2
2(4x+2) = 5x+13
8x + 4 = 5x+13
8x - 5x = 13 -4
3x = 9
x = 3
Answer:
24.997 cm
Step-by-step explanation:
Find the diameter:
7(2) = 14 cm
Find the circumference:
C = 
C = 
C = 43.988
Divide the circumference by 4:
43.988/4 = 10.997
(This is the length of the curved side)
Add length to the other 2 sides:
7 + 7 + 10.997 = 24.997
