Answer:
y = 6
Step-by-step explanation:
Formula
Chords intersect in such a way that QU * SU = RU * TU
Givens
- QU = 8
- SU = y
- RU = 12
- TU = 4
Solution
- 8 * y = 12 * 4
- 8y = 48
- 8y/8 = 48/8
- y = 6
P(A | B) is 2/10 = 0.2.
<h3>What is
P(A | B) ?</h3>
P(A | B) means the probability that a students pays both basketball and football. It is the intersection of both circles on the venn diagram.
P(A | B) = number of students that play both games / total number of students
2/10 = 0.2

Answer: A.
Step-by-step explanation: if you look close enough, you can see exactly how long it is, and see that it does also have the two arrows along with it, but it’s the exact same just tilted a little bit but trust me I believe he correct answer is A.
Answer:
15) 3.2
17) 13.4
Step-by-step explanation:
To find the missing lengths, you need to use the Pythagorean theorem:
a² + b² = c²
In this form, "c" represents the length of the hypotenuse and "a" and "b" represent the lengths of the other two sides.
You are trying to find one of the side lengths (not the hypotenuse) in 15). To find the other length, you can plug the other values into the equation and simplify to find "b".
15) a = 4.1 c = 5.2
a² + b² = c² <----- Pythagreom Theorem
(4.1)² + b² = (5.2)² <----- Plug values in for "a" and "c"
16.81 + b² = 27.04 <----- Raise numbers to the power of 2
b² = 10.23 <----- Subtract 16.81 from both sides
b = 3.2 <----- Take the square root of both sides
You are trying to find the hypotenuse in 17). Since you have been given the lengths of the other sides, you can plug them into the equations and simplify to find "c".
17) a = 4.4 b = 12.7
a² + b² = c² <----- Pythagreom Theorem
(4.4)² + (12.7)² = c² <----- Plug values in for "a" and "b"
19.36 + 161.29 = c² <----- Raise numbers to the power of 2
180.65 = c² <----- Add
13.4 = c <----- Take the square root of both sides
