Step-by-step explanation:
This question requires you to use the Pythagorean Theorem. If you're not sure what this is, I'll explain it to you.
The formula itself is: a²+b²=c²
A triangle is composed of two legs and one hypotenuse. The hypotenuse will always be the longest side.
Look at the picture I attached. Here, I helped you label the two legs and the hypotenuse! Now, what do a,b, and c represent in the equation? a will be the first leg, b will be the second leg, and c will be the hypotenuse.
--------------------------------------------------------------------------------------------------------------
So, the word problem already gives you two values: the length of the ladder (15') and the height of the wall (12'). If you're having trouble imagining it, look at the second picture I attached where I label the objects with the values they give you. Now we just have to find the missing side.
For the sake of consistency, we're going to call the missing side b. The wall will be a and the ladder will be c. (Go back to the first picture if you're confused.)
Now, we're finally at the part where we plug in our values! All you need to do is put your a and c value into the equation, then solve for b. So:
--------------------------------------------------------------------------------------------------------------
12²+b²=15²
(Input 12² and 15² into a calculator unless you've memorized your squares)
Once we square 12 and 15 we get:
↓
144+b²=225
------
Now, the first thing we need to do is get b by itself on one side. So we'll subtract 144 from both sides.
------
↓
144+b²=225
-144 -144
↓
b²=225-144
↓
b²=81
------
Okay, so now we have to get rid of the square over the b. What's the opposite of squaring? (We do the opposite to cancel things on each side, like how we subtracted 144 from each side because it was positive.) That would be finding the square root. So if we do the square root of b, we must do the same thing to the other side:
↓
√b²=√81
(Type √81 into a calculator unless you've memorized it.)
↓
b=9
--------------------------------------------------------------------------------------------------------------
Aaaand... wah-la! We've now found the value of b, or how far from the base of the house we need to be to place a 15' ladder to exactly reach the top of a 12' wall.
I hope you were able to understand my explanation. Please comment if you have any further questions; I will be glad to answer them!

What is the difference between mean and median
Answers
The difference between the mean and median is that the mean is the average number. f.e: 1, 2, 2, 2, 3, 3, 4, 5 - and if you add all those up, the mean would be 3, or 2.
But the median is the number in the middle Number.
What if you have 2 medians, though?
Well, that’s easy to solve IMO.
F.e: 22, 22, 23, 23, 23, 24, 24, 24, 25, 25
The median is either 23 or 24, right?
Okay. That’s simple. But what exactly do we do?
Let me show you:
So get the sum of 23 and 24, which is 47.
Now divide 47 by 2. And what do we get?
23.5.
Now round that, and you get 24. So 24 is the median!
Hope that helps!
Answer:
mean is the AVERAGE of all numbers
Step-by-step explanation:
because when you add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS!
and a median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.

John has a bag of red and blue marbles. John chooses 2 marbles without replacing the first. Let A be the event where the first marble chosen
is red. Let B be the event where the second marble chosen is blue.
Answers
The conditional probability of an event depends on the occurrence of another event. The correct option is C.
What is Bayes' Theorem?The conditional probability of an event depending on the occurrence of another event is equal to the likelihood of the second event given the first event multiplied by the probability of the first event, according to Bayes' Theorem.
Suppose that there are two events A and B. Then suppose the conditional probability is:
P(A|B) = probability of occurrence of A given B has already occurred.
P(B|A) = probability of occurrence of B given A has already occurred.
Then, according to Bayes' theorem, we have:
[tex]\rm P(A|B) = \dfrac{P(B|A)P(A)}{P(B)}[/tex]
(assuming the P(B) is not 0)
Given John has a bag of red and blue marbles. John chooses 2 marbles without replacing the first. Let A be the event where the first marble chosen
is red. Let B be the event where the second marble chosen is blue. Therefore, the Probability P(B|A)=0.6 is described as the probability of choosing a blue marble after a red marble has been removed is 0.6.
Hence, the correct option is C.

Tannis's first machine could throw a car 27 meters. She studied her first machine and built a better one. Her second machine could throw a car 7 times as far.
How far does the second machine throw a car?
Answers
Answer:
Hello! Your answer would be 189 meters.
Step-by-step explanation:
First, let's examine the problem closely. It says that Tannis's first machine could throw a car 27 meters, but then she studied her first machine and built another one. So far we have one part of the problem that will get us to our solution, 27 meters. The next part is where we get our last two parts of our problem, the operation and the other factor. The second part of this problem says that Tannis's second machine could throw a car 7 times as far, meaning her second machine could throw a car 7 times farther then her first machine. We are given our operation, multiplication, first, and our second factor, 7, last. Then, we must look closely at the main question we are trying to answer: How far does the second machine throw a car? We can form and evaluate an expression to answer this question. With the information we've gathered, we can form the expression: 27 meters x 7, and that equals 189 meters. I hope this helps and make sure you have an amazing day!
The distance travelled by the second machine is 189 meters.
What is mathematical operations?
The mathematical “operation” refers to calculating a value using operands and a math operator.
What will be the distance travelled by second machine?According to question, Tannis's initial machine could toss a car 27 meters, but after studying it, she constructed a new one.
We currently just have the 27 meters portion of the problem, which will lead us to the answer.
The second portion of the equation states that Tannis's second machine could toss a car seven times farther than her first machine, or seven times as far.
Our operation, multiplication, comes first, followed by our second factor, 7, in that order. With the knowledge we have acquired, we may formulate the formula: 27 meters times 7 = 189 meters.
Therefore, the correct answer is 189 meters.
