What is the probability that Mrs. Chevalier names a positive integer?
Part B
Explain how you determined your answer.
Answers
Answer:
(15/31) ?
Step-by-step explanation:
|-15| = 15
15+15+1 (for 0) = 31
1 through 15 are positive, so 15 of the 31 could be positive, or 15/31
Sorry, could be wrong, but I think it's right
Part B: Numbers from -15 to 15 is thirty-one total numbers including zero, but zero is neither negative nor positive, so it doesn’t really count in this situation unless the instructions describe it as positive. Without the zero, it is thirty numbers in total, with half of them being negative, and half of them being positive, which can also be said as 50%. You can find this answer by dividing 15 by 30, which is 1/2, or 50%.
-4(x-1)=-3x+13-9-x
PLS SOLVE IT STEP BY STEP
Answers
-4x+4=-3x+4-x
-4x+4=-4x+4
-4x=-4x
0=0
Answer:
x can be any real number.
Step-by-step explanation:
- 4 (x - 1) = - 3x + 13 - 9 - x
The easiest approach to solving this problem is to simplify each side. Start by focusing on the left side, distribute the term outside of the parenthesis, multiply every term inside the parenthsis by the term outside of it,
- 4 ( x - 1 ) = - 3x + 13 - 9 - x
Distribute,
(-4)(x) + (-4)(-1) = - 3x + 13 - 9 - x
Simplify,
-4x + 4 = - 3x + 13 - 9 - x
Simplify the right side of the equation, combine like terms,
-4x + 4 = - 3x + 13 - 9 - x
Rearrage,
-4x + 4 = -3x - x + 13 - 9
Simplify,
-4x + 4 = -4x + 4
At this point, one should use inverse operations to solve the problem, but the given equation is an identity, meaning that any real value can be substituted into the parameter (x), and the equation will yield a true result. Thus, (x) equals all real numbers.

Answer:
Answer In Explanation
Step-by-step explanation:
O More Than Half Of The Students Scored 81 Or Better
O The Same Number Of Students Scored Between 81 And 90 On The Test As Scored Between 61 And 80
-The Last One Is Confusing Because It Doesn't Say 71-80
Options (B) and (D) are true statements that describe the data in the histogram are the correct answers.
What is a histogram?A histogram is a visual way to display frequency data using bars. It is a chart that shows frequencies for intervals of values of a metric variable. It is a display of statistical information that uses rectangles to show the frequency of data items in successive numerical intervals of equal size.
For the given situation,
The histogram shows the scores on a recent science test.
We need to check the options, which statements describe the data.
Option A: Only two students scored less than 71 on the test.
There are four students scored less than 71.
So option A is false.
Option B: More than half of the students scored 81 or better on the test.
Students scored more than 81 = [tex]16+8[/tex]
⇒ [tex]24[/tex]
Total number of students = [tex]40[/tex]
Half of the students = [tex]\frac{40}{2}[/tex]
⇒ [tex]20[/tex]
Thus, [tex]24 > 20[/tex]
So option B is true.
Option C: More students scored between 91 and 100 on the test than scored between 71 and 80.
Students scored between 91 and 100 = [tex]8[/tex]
Students scored between 71 and 80 = 12
⇒ [tex]8 < 12[/tex]
So option C is false.
Option D: The same number of students scored between 81 and 90 on the test as scored between 61 and 80.
Students scored between 81 and 90 = [tex]16[/tex]
Students scored between 61 and 80 = [tex]4+12[/tex]
⇒ [tex]16[/tex]
Thus, [tex]16=16[/tex]
So, option D is true.
Option E: There were 12 students who scored 80 on the test.
The score range is between 71 to 80. So we could not predict the number of students who score 81.
So option E is false.
Hence we can conclude that options (B) and (D) are true statements that describe the data in the histogram are the correct answers.

Answers
Answer:
A = 60°
Step-by-step explanation:
First to find the missing angle you add the three known angles,
90 + 135 + 75 = 300
Then, you subtract, 360 - 300 = 60
So, 360° = 60° + 90° + 135° + 75°Answer:

Sorting it in order: 7, 8, 9, 10, 11, 12, 13
To find the median: Look for the middle number. In this case, the middle number is 10.
To find the 1st quartile: The first quartile is the median of the first half of the data. So, the first half of the data is 7, 8, 9. The median is 8.
To find the 3rd quartile: The third quartile is like the 1st quartile, but it's on the other end. So, it contains 11, 12, 13. The median of that is 12.
To find the maximum: The maximum is the largest number in the data set. So, in this case, it is 13.
To find the minimum: The minimum is the smallest number in the data set. In this case, it is 7.
Data in all: median: 10 1st Quartile: 8 3rd Quartile: 12 Min: 7 Max: 13
