5. How many fewer students are there who ran 1 mile in under 10 minutes than students who took 11 or more minutes to run that distance?
nothing
6. Can you tell from the frequency table how many students, if any, ran a mile in exactly 12 minutes? Explain.
No/Yes, because the frequency table shows only frequencies/only ranges of times/exact times.
PLZ HURRY WILL MARK BRAINLIEST
Answer:
3. 31
4. 6
5. 7
6. No because the frequency table shows only ranges of times.
Step-by-step explanation:
3. Add up the number of students in each section of your table:
6 + 2 + 8 + 6 + 9 = 31
4. Only the first group ran under 9 minutes.
5. 8 students ran 1 mile in under 10 minutes (the first two sections)
15 students took 11 or more minutes to run 1 mile (the last 2 sections)
15 - 8 = 7
6. No, because the frequency table shows only ranges of times.
There are 31 students in PE class, 6 students ran 1 mile in under 9 minutes, 8 students are there who ran 1 mile in under 10 minutes than students who took 11 or more minutes to run that distance and no student ran a mile in exactly 12 minutes.
What is Statistics?A branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data
A frequency distribution table is a method to organize the data given so that it makes it more meaningful and easier to understand.
The given frequency table
Time Number of students
8:00-8:59 6
9:00-9:59 2
10:00-10:59 8
11:00-11:59 6
12:00-12:59 9
3. The number of students in the PE class
6+2+8+6+9
=31
4. Only the first group ran under 9 minutes which is 6 students
5. 8 students ran 1 mile in under 10 minutes
6+2=8
15 students took 11 or more minutes to run 1 mile
15 - 8 = 7
6. No, because the frequency table shows only ranges of times.
Hence there are 31 students in PE class, 6 students ran 1 mile in under 9 minutes, 8 students are there who ran 1 mile in under 10 minutes than students who took 11 or more minutes to run that distance and no student ran a mile in exactly 12 minutes.

Which expression is equivalent to -3x(x-4)-2x(x+3)?
Answer:
x(x^2 + 6)
Step-by-step explanation:
We are to simplify -3x(x-4)-2x(x+3). Begin by performing the indicated multiplication. We get -3x^2 + 12x - 2x^2 - 6x.
Combining like terms, we get -5x^2 + 6x, which is equivalent to
x(x^2 + 6)
Answer
=5x²+12x-6
Step-by-step explanation:
you multiply -3x(x-4)-2x(x+3)
=-3x²+12x-2x²-6
group like terms
=-3x²-2x²+12x-6
=-5x²+12x-6

The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function? Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points. Locate the ordered pair (0, –6). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points. Locate the ordered pair (–6, 0). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points. Locate the ordered pair (–6, 0). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.
Answer:
A because (0,-6) is the y-intercept so you start at the point you know. Then because slope is a rise over run fraction the slope can also be written as 2/1 which is rise 2 over 1.
Step-by-step explanation:
w
Answer:
A, cuz (0,-6) is the y-intercept. You start at the point that is familiar to u. Then cuz slope = rise over run, simplify the slope which is 2/1.
how many more numbers to get from 675 to 800
Answer:
Subtract 675 by 800, and you will get 125
To get from 675 to 800, you will add 125 to 675
Answer:
125
Step-by-step explanation:
675+1+1+1+1+1+1+1
lol just kidding
If you subtract 800-675, you would get 125.
Also if you added 125 to 675, you would get 800.

A circle has a diameter of 36 cm. Which expression could represent the area of this circle in square cm?
Answer:
Step-by-step explanation:
You haven't given the choices but I believe the equation below could represent the area of the circle:
(pi ~ 3.14) * (18)^2
The area for a circle is pi * radius squared, so to find the radius divide the diameter by 2.

Step-by-step explanation:
In order to find the number of solutions, we have to expand both sides out first.
[tex]3(x - 2) + 7x = \frac{1}{2} (6x - 2)[/tex]
First, expand 3(x-2), which will obtain 3x-6.
Next, expand (1/2)(6x-2), which gives 3x - 1.
The result at this point should be as shown below:
[tex]3x - 6 + 7x = 3x - 1[/tex]
Now, we would shift all x terms to the left and all number terms to the right.
[tex]3x + 7x - 3x = - 1 + 6[/tex]
After simplifying, the final equation would be:
[tex]7x = 5[/tex]
This is a linear equation and it has one solution.
