In a math class with 19 students, a test was given the same day that an assignment
was due. There were 12 students who passed the test and 13 students who completed
the assignment. There were 4 students who failed the test and also did not complete
the assignment. What is the probability that a student completed the homework given
that they passed the test?

Answers

Answer:  5/6

======================================================

Work Shown:

A = number who passed test, and did the hwB = number who passed test, but didn't do the hwC = number who failed test, but did the hwD = number who failed test, and didn't do the hw

With a class total of 19, we know that A+B+C+D = 19.

12 students passed the test, which leaves 19-12 = 7 people who failed the test.

Of these 7 people who failed the test, 4 of them didn't do the hw. This leads to D = 4.

Note how C+D = 7 becomes C+4 = 7 and it solves to C = 3.

Since 13 people did the hw, we can say A+C = 13. Plug in that value of C we found earlier, to find that A = 10.

Lastly, solving A+B = 12 leads to B = 2.

------------

To summarize what we found so far:

A = 10B = 2C = 3D = 4

Now onto the question your teacher is asking: "What is the probability that a student completed the homework given that they passed the test?"

The key phrase here is "given that they passed the test". Because of this phrase, we'll ignore anyone who didn't pass. We'll focus solely on the 12 students who passed. Of those 12 who passed, we found that A = 10 people did the hw.

Therefore, the probability of picking someone who did the hw, given the passed the test, is 10/12 = 5/6

In at least five (5) sentences, explain the effects of changing the “m" and the "b" in y=mx+b.
What happens when we use negative numbers for m? What happens when we use negative
numbers for b?

Answers

Changing the “m” or “b” would change the overall line on the graph. Meaning the line could be steeper or flatter. It could also change whether the line has a positive slope or negative. Likewise, when you use negative numbers for the m, the line will have a negative slope and will have a decreasing look to it. When you use negative numbers for the b, the y-intercept will be negative which will put the line further down the y-axis.

I hope this is what you were looking for! I kinda did it off the top of my head so of course feel free to change anything!!

Manuel wants to replace the wooden floor at his gym. The floor is in the shape of a rectangle. Its length is 50 feet and its width is 25 feet. Suppose wood flooring costs $8 for each square foot. How much will the wood flooring cost for the floor?

Answers

Answer:

$ 10,000

Step-by-step explanation:

Manuel wants to replace the wooden floor at his gym. The floor is in the shape of a rectangle. Its length is 50 feet and its width is 25 feet.

The gym floor is shaped like a rectangle

Area of a rectangle = Length × Width

= 50 feet × 25 feet

= 1250 ft²

Suppose wood flooring costs $8 for each square foot.

The wood flooring cost for the floor is calculated as

1 ft² = $8

1250ft² = x

Cross Multiply

1250 ft² × $8

$ 10,000

The wood flooring cost for the floor is $10,000

Carla and Deserea bought a dozen cookies from the bakery. Carla ate ¼ of the cookies and Deserea ate ½ of the cookies. Who ate the most

Answers

Answer:

The answer is Deserea.

Step-by-step explanation:

Dont worry, this is simple :)

If you have a dozen cookies, that means you have 12 cookies!

And 1/4 of 12 is simply 12 divided by 4, which equeals 3, so Carla ate 3 cookies.

And Deserea ate ½ of the cookies, which is 12 divided by 2, which is 6! So Deserea ate 6 cookies.

6 is greater than 3. So Deserea ate more Cookies!

Hope this helps!

Deserea Ate the most because 1/2 is a lot more than 1/4. Hope this helps :-)

Which side lengths form a right triangle? please help

Answers

In a right triangle, the side that is opposite of the 90° angle is the longest side of the triangle, and is called the hypotenuse. The sides of a right triangle are commonly referred to with the variables a, b, and c, where c is the hypotenuse and a and b are the lengths of the shorter sides.

you should square each of the smaller numbers and add them together. after that square the bigger number. if the results gotten is equivalent, it is a right angled triangle. feel free to clarify. I used pythagoras theorem to solve this btw

List a positive and negative number whose absolute value is greater than 3?​

Answers

Answer: |5|, |-6|, |4|, |-3.5|

Step-by-step explanation: The absolute value is related with the distance between the number and the zero of the number line, then each number greater than 3 will have an absolute value greater than 3, as we can see in the picture, the numbers positive or negative will have a positive distance to the origin of the number line.

Use the drop-down menus to show and explain your answer. Is correct because you the greatest and least lengths represented by the , not the number of at the greatest and least lengths.

Answers

The drop downs cannot be viewed.

Answer:

Joseph is correct

Step-by-step explanation:

To obtain the difference between the longest and shortest length of the rope ; all we need to do is find the range of the dot plot ; The value for the range is obtained thus ;

Range = Highest - Least value

Highest value or maximum = 12 feets

Minimum or least = 9 1/2 feets

The Range = difference between the longest and shortest length is : (12 - 9 1/2) feets = 2 1/2 feets
