Determine whenever each statement about the scatter plot is true or false
The plot shows an outlier value when the time studied is equal to 75 minutes
Answer:False
Step-by-step explanation:
In a class test of 15 questions, (+4) marks are given for every correct answer, (– 2) marks are
given for every incorrect answer and 0 marks are given for questions that are not attempted. Punit
scored (– 2) marks. If he answered 3 questions correctly, how many did he get wrong? How many
questions did he not attempt?
If he answered 3 questions correctly, then the number of questions is got wrong is 7 and the number of questions that he did not attempt is 5.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
In a class test of 15 questions, (+4) marks are given for every correct answer, (– 2) marks are given for every incorrect answer, and 0 marks are given for questions that are not attempted. Punit scored (– 2) marks.
If he answered 3 questions correctly, then the number of the question are got wrong and the number of the question that he did not attempt.
Let x be the correct question and y be the incorrect question, z be the number of questions that he did not attempt, and A be the number of the total score. Then we have
4x – 2z = A
x + y + z = 15
If A = -2 and x = 3, then we have
4 × 3 – 2z = -2
12 + 2 = 2z
z = 7
Then the value of y will be
3 + y + 7 = 15
y = 5

Enter the value of x that makes the equation −11(x + 4) + 10x = 27 true
Answer:
x = - 71
Step-by-step explanation:
-11x -44 + 10 x =27
-x = 71
x = - 71
Answer:
-71
Step-by-step explanation:
You can first distribute the numbers in the parenthesis.
-11x-44 (-11*x-11*4)
-11x-44+10x=27
You can now combine like terms.
-11x+10x=-1x
-1x-44=27
This is now a two-step equation problem.
-1x-44=27
+44=+44
-1x=71
[tex]\frac{-1x}{-1}[/tex] =[tex]\frac{71}{-1}[/tex]

The perimeter of a rectangular garden is 264 m.
If the width of the garden is 56 m, what is its length?
Length of the garden:__m
Step-by-step explanation:
Perimeter of garden = 264 m
width of the garden = 56 m
length of the garden = ?
Now..
Perimeter = 2 ( l + b )
264m = 2l + 112
264 - 112 = 2l
152 = 2l
l = 152 / 2
l = 76 m
Hence the length is 76m

A survey asks teachers and students whether they would like the new school mascot to be a Viking or a Patriot. This table shows the results. Vikings Patriots Total Students 80 20 100 23 Teachers 5 20 25 Total 85 40 125 A person is randomly selected from those surveyed. Are being a student and preferring "Viking" independent events? Why or why not? = A. No, they are not independent because P(student) = 0.80 and P(student|Viking) =0.94. B. Yes, they are independent because P(student) = 0.80 and P(student|Viking) = 0.94 C. No, they are not independent because P(student) = 0.80 and A(student|Viking) = 0.68. KOTID D. Yes, they are independent because P(student) = 0.80 and P(student|Viking) = 0.68.
Using conditional probability, it is found that the correct option regarding whether the events are independent is given by:
A. No, they are not independent because P(student) = 0.80 and P(student|Viking) =0.94.
What is Conditional Probability?Conditional probability is the probability of one event happening, considering a previous event. The formula is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which:
P(B|A) is the probability of event B happening, given that A happened.[tex]P(A \cap B)[/tex] is the probability of both A and B happening.P(A) is the probability of A happening.An event B is classified as independent if:
P(B|A) = P(B).
In this problem, 100 out of the 125 people sampled are students, hence the probability is given by:
P(student) = 100/125 = 0.8.
Out of the people that prefer to be a Viking, 80 out of 85 people are students, hence:
P(student|Viking) = 80/85= 0.94.
The probabilities are different, hence the events are not independent, and option A is correct.

In numbering pages of a book, a printer used 3289 digits. How many pages were in the book, assuming the first page of the book was number 1? Justify your answer. (b) Find the number of digits the printer will need for a book with n pages, for any positive integer n. Write this function of n as simple a form you can.
The number of the pages in the book if the first page will be numbered as 1 will be 1099 pages. And if the number of the pages is n then the function is shown below.
What is Algebra?Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.
In numbering pages of a book, a printer used 3289 digits.
Then the number of the pages in the book if the first page will be numbered as 1.
One digit number = 1 - 9 = 9 digits
Two digit number = 10 - 99 = 2 x 90 = 180 digits
Three digit number = 100 - 999 = 3 x 900 = 2700 digits
Then the total number of the digit is used will be
→ 9 + 180 + 2700
→ 2889
The number of the remaining digits will be
→ 3289 - 2889
→ 400
Then the four-digit number will be
→ 400/4
→ 100
Then the total number of the pages will be
Total pages = 9 + 90 + 900 + 100
Total pages = 1099
If n pages are there, then the number of the digits are required will be

Step-by-step explanation:

A number cube is rolled. Identify the probability of getting 1 or 6 as a fraction, as a decimal to the nearest hundredth, and as a percent to the nearest whole percent.
1/3, 0.33, 30%
1/3, 0.33, 33%
2/3, 0.33, 30%
2/3, 0.67, 67%
Answer: The second option, 1/3, 0.33, 33%
Step-by-step explanation:
We will put the number of wanted outcomes over the number of total outcomes. 1 and 6 is two wanted outcomes.
2 / 6 = 1/3
Now, 1/3 is equal to 0.33. A decimal multiplied by 100 is a percent, so it is also equal to 33%. Your answer is:
1/3, 0.33, 33%
find the missing angles.
Answer:
1. 37 degrees, 2. 39 degrees, 3. 27 degrees
Step-by-step explanation:
You look at the total angle and subtract it by the angle that is given in the question since the two angles should add up to the whole angle of both. You should look at the number that is outside the angles and subtract it by the angle number inside then you will get the missing angles. The last one it is showing a 90 degree angle which is formed so you subtract 63 from 90.
Convert the rectangular equation to polar form. X2 y2 = 64
The polar form of the equation represents all the points with a distance of 8 from the origin, which is a circumference with a radius of 8, centered on the origin.
What is the polar form of the equation?The polar form is represented with the aid of polar coordinates of real and imaginary numbers in the coordinate system.
The horizontal and the vertical axis of the polar form denote the real axis and the imaginary axis, respectively.
The given equation to polar form is;

At a sale this week, a desk is being sold for 128.80. This is a 72% discount from the original price. What is the original price?
Answer:
$460
Step-by-step explanation:
If the 128.80 is the price of the desk after a 72% discount, it means that 128.80 is 100-72=28% of the original price.
From here, we can divide 128.80 by 28 to find what 1% of the price is then multiply the value by 100 to find 100%, or the original price.
128.80/28 = 4.6
4.6 x 100 = 460
Original price = $460

It took Vaughn 3 hours to drive to his sisters house. He took the same route on the way back home, but this time the trip took 2.5 hours. If Vaughn drove 10 mph faster on his return trip, how fast did he drive on his way to his sisters house?
The speed to his sister house is 50mph.
What is Speed?The speed of an object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.
Here, let the speed of his sisters house be x mph.
then, 3x = 2.5(x+10)
3x = 2.5x + 25
3x - 2.5x = 25
0.5x = 25
x = 25 / 0.5
x = 50
