We can evaluate the mean, median, standard deviation and many other statistical measures from the stem-leaf table.
What is mean?It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
From the stem leaf table, we can find different statistical measures.
From the picture attached, we can find different data
The minimum value = 12
The maximum value = 49
Total number of observation = 30
The sum of the all data = 986
Mean of the data = 986/30 = 32.87
Median of the data = 34.5
Standard deviation = 11.24
Variance = 126.4
Thus, we can evaluate the mean, median, standard deviation and many other statistical measures from the stem-leaf table.

Find the missing value
Answer:
the answer to this question is 19
Answer: m=19
Step-by-step explanation:
First you cross multiply the two fractions. So you get 9*m = 57*3.
When you put 57*3 in a calculator you get 171. So the equation is 9m=171 and then to isolate the x you divide by 9. So when you put 171/9 in a calculator you get 19. So the correct answer is C. 19.

Points O, C, and P are collinear with O(−10, −8) and P(−2,8). Point C divides the line segment OP into the ratio 3: 5. What are the coordinates of point C?
Using proportions, it is found that the coordinates of point C are given as follows: C(-7, -2).
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Point C divides the line segment OP into the ratio 3:5, hence the following equation is used to relate the points:
[tex]C - O = \frac{3}{8}(P - O)[/tex]
Then, for the x-coordinate:
[tex]x + 10 = \frac{3}{8}(-2 + 10)[/tex]
x + 10 = 3
x = -7
For the y-coordinate:
[tex]y + 8 = \frac{3}{8}(8 + 8)[/tex]
y + 8 = 6
y = -2

write the equation in standard form for the circle passing through (-3,0) centered at the origin.
Answer:
x^2 + y^2 = 9
Step-by-step explanation:
The equation of a circle is (x^2) -a)^2 + (x^2) - b)^2 = r^2, where a and b are the center of the circle. Because the center of the circle is (0,0), it'll just be x^2+y^2 for one half of the equation. If the circle passes through (-3,0), that would mean the radius of the circle is 3. r^2 is 3^2, which is 9, so the equation of the circle is x^2 + y^2=9. Hope this helps!
The equation of the circle is x² + y² = 9
What is a Circle?A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the point be represented as A ( -3 , 0 )
Now , the center of the circle = O ( 0 , 0 )
And , standard form of a circle is
( x - h )² + ( y - k )² = r²
where In this case, we know that the circle passes through the point (-3, 0) and is centered at the origin (0, 0). Therefore, the radius of the circle is the distance from the origin to (-3, 0), which is:
r = √((-3 - 0)² + (0 - 0)²) = √(9)
r = 3 units
So the equation of the circle in standard form is:
(x - 0)² + (y - 0)² = 3²
On simplifying , we get
x² + y² = 9
Hence , the equation in standard form for the circle passing through (-3,0) centered at the origin is x² + y² = 9

Find the equation of the line that passes points
A(1,7)B(-3,-1)
Answer:
y = 2x + 5
Step-by-step explanation:
Here we have the two points as (x1=1, y1=7) and (x2 = -3, y2 = -1)
Slope of this line = (y2-y1)/(x2-x1) = (-1 -7)/(-3 - 1) = 8/4 = 2
Using slope intercept form of y = mx + c
we get y = 2 x + c
Substituing the coordinates (1,7) in this equation gives us
7 = 2.1 + c or c =5
hence y = 2x + 5
Check
if x = -3 then y = (-2)(-3) + 5 = -6 + 5 = -1 which satisfies the coordinates for the second point

Answer:
128 cubes can fit in.
Step-by-step explanation:
We are given: Volume of rectangular prism = 2 units³ and Cube with edge = 1/4 unit
We must find: The number of cubes that can fill the prism
Firstly, find the volume of 1 cube:
Volume = 1/4 x 1/4 x 1/4
Volume = 1/64 units³
Next find the number of cubes that can go into the prism:
Number of cubes = 2 ÷ 1/64
Number of cubes = 128
Therefore 128 cubes can fit in.

Find the median and mean of the data set below:
47,15, 6, 49, 45, 30
Answer:
The median of the data set:
6, 15, 30, 45, 47, 49
The middle numbers are 30 and 45 so
You have to do 30 + 45
= 75
Then do 75 ÷ 2
= 37.5
The mean of the data set:
47, 15, 6, 49, 45, 30 (add them all)
= 192
Then divide 192 by 6 (because there are 6 numbers)
192 ÷ 6
= 32
So the median is 37.5 and the mean is 32.

Brooke is located 5 miles out from the nearest point A along a straight shoreline in her sea kayak. Hunger strikes and she wants to make it to Kono's for lunch; see picture. Brooke can paddle 7 mph and walk 14 mp
If she paddles along a straight line course to the shore, find an expression that computes the total time to reach lunch in terms of the location where Brooke beaches her kayak (so x = distance from A to where she lands). Be sure you remember the formula that relates Distance, Rate and Time. You're being asked for Time here
If she paddles directly to Kono's then the minimum time for the lunch will be 3.9 hours.
What is kinematics?It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
Brooke is located 5 miles out from the nearest point A along a straight shoreline in her sea kayak.
Hunger strikes and she wants to make it to Kono's for lunch; see picture.
Brooke can paddle at 7 mph and walk at 14 mph.
Distance from Brooke to shore will be
→ √(5² + x²)
Then the time will be
[tex]t_1 = \dfrac{\sqrt{5^2 + x^2}}{2}[/tex]
Then the distance from shore to Kono's will be
→ 6 - x
Then the time will be
t₂ = (6 - x) / 4
Then the total time will be
t = t₁ + t₂
Then we have
[tex]t = \dfrac{\sqrt{5^2 +X^2}}{2} + \dfrac{6-x}{4}\\[/tex]
t = 1/4[2√(5² + x²) + 6 - x]
If she paddles directly to point A will be
t = 1/4[2√(5² + 0²) + 6 - 0]
t = 1/4 (10 + 6)
t = 16 /4
t = 4 hr
If she paddles directly to Kono's, then we have x = 6. Then the time will be
t = 1/4[2√(5² + 6²) + 6 - 6]
t = 1/4[2√61]
t = 3.9 hr
