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.

How many faces have an area of 6 cm2?
Answer:
2
Step-by-step explanation:
There are 6 sides:
3 by 4 = 3*4 = 12, no
3 by 3 = 3*3 = 9, no
5 by 3 = 5*3 = 15, no
Triangles:
Half of 3 by 4 = 1/2 * 3* 4 = 1/2 * 12 = 6, yes
The other triangle is the same, so 2
Answer:
two
Step-by-step explanation:
Area of the rectangle on the left = 4 * 3 = 12 cm^2
area of the square = 3^2 = 9 cm^2
Area of the rectangle on the right = 5 * 3 = 15 cm^2
Area of the two triangles = (4 * 3)/2 = 6 cm^2

twice as many as the number of sides
half as many as the number of sides
the same number as the number of sides
Answer:
the same number as the number of sides
lines of symmetry are in a regular polygon is the same number as the number of sides.
the correct option is (D)
What is Line of symmetry?A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly.
The number of lines of symmetry in a regular polygon is equal to the number of sides.
For example,
It has four lines of symmetry and four sides. A regular pentagon has 5 sides and 5 lines of symmetry.
Hence, lines of symmetry in a regular polygon is equal to the number of sides.

Find the volume of this prism.
The volume of the prism is 420 in³.
Option C is the correct answer.
We have,
From the figure,
Length = 7 in
Width = 5 in
Height = 12 in
Now,
To find the volume of the prism, we can use the formula:
Volume = Length * Width * Height
Substituting these values into the formula:
Volume = 7 * 5 * 12
Simplifying the expression:
Volume = 420 cubic inches
Thus,
The volume of the prism is 420 in³.
