The easiest way to solve this problem is to make a table, based on 100 total person

 Prefer week ends Prefer week days Total

Female 10 55 65

Male 15 20 35

Total 25 75 100

The bold numbers are conclusions. The plain numbers are data.

The probability that a randomly selected club member is female, given that that person prefers swimming on weekends is [10 / 25] = 0.40

Which group of three squares will form a right triangle when joined at their vertices?

Ilia_Sergeevich [38]

Answer:

Option ?) 17 cm, 15 cm, 8 cm

The assignment should have four options to choose from, but there is only a picture of two.

Step-by-step explanation:

None of the squares shown form a right triangle. To determine if sides form a right triangle, you use this formula:

a²+b²=c²

We are given two options in the picture.

Option A) 18, 10, and 8.

Option B) 12, 9, and 6.

So, now we need to apply the formula:

Option A)

║8² + 10² = 18²

↓

║64 + 100 = 324

↓

║FALSE

Option B)

║6² + 9² = 12²

↓

║36 + 81 = 144

↓

║FALSE

Both of these options are false. But, I decided to look up this assignment to check my answer. It turns out, there are 4 options, and you only had a picture of two. So, what's the answer?

There is an answer choice that shows 3 squares with the lengths of 17 cm, 15 cm, and 8 cm. This is the correct answer.

For proof, let's apply the formula:

Option ?)

║8² + 15² = 17²

↓

║64 + 225 = 289

↓

║TRUE

[Since the option isn't shown, I'll put a '?' so there is no confusion]

List an example of two events that are independent. (b) list an example of two events that are dependent. (a) list an example

Nookie1986 [14]

When two events are dependent, this means that one event cannot occur without the other, or simply put the two events are connected to each other in one way or the other.

When two events are independent, this means that the two events can occur separately, with one event having no effect on the occurrence of the other.

Therefore the dependent and independent events are as follows:

Independent event:

c. rolling a die twice

The outcome of the first die does not affect the outcome of the second die, hence independent.

Dependent event:

d. drawing one card from a standard deck, not replacing it, and then selecting another card

By the act of not replacing the drawn card, we are changing the probability of selecting another card, hence dependent.
