Ramiro did a survey of the number of pets owned by his classmates, with the following result
What was the mean Deviation of the number of pets?
A-1.02
B-1.053
C-1.087
D-1.12
The mean deviation of the number of pets Ramiro surveyed as shown in the table attached below is: D. 1.12
To find the mean deviation of the number of pets, the following steps would be taken:
Find the mean, which is sum of each frequency and score (fx) divided by the total number of pets. \(\mathbf{(\frac{\sum fx}{n} )}\)Subtract the mean from each score, \(\mathbf{( x - \bar x)}\)Sum the deviations together and divide by total number of pets.The formula for the mean deviation is given as: \(\mathbf{\frac{\sum f* |x - \bar x|}{n} }\)Mean deviation as solved in the table attached in the image below would be:
\(\mathbf{\frac{33.6}{30} = 1.12}\)
Therefore, the mean deviation of the number of pets Ramiro surveyed as shown in the table attached below is: D. 1.12

Solve the following system of equations.
{x+4y=0
{16y=−4x
Answer:answer (0,0)
Linear equations with two unknowns
Enter an equation or problem
x+4y=0;16y−4x
We think you wrote
x+4y=0;16y-4x
This solution deals with linear equations with two unknowns.
Solution found
{x,y}={0,0}
See steps
Step by Step Solution
System of Linear Equations entered :
[1] x+4y=0
[2] 16y-4x
Equations Simplified or Rearranged :
[1] x + 4y = 0
[2] -4x + 16y = 0
Graphic Representation of the Equations :
4y + x = 0 16y - 4x = 0
Solve by Substitution :
// Solve equation [1] for the variable x
[1] x = -4y
// Plug this in for variable x in equation [2]
[2] -4•(-4y) + 16y = 0
[2] 32y = 0
// Solve equation [2] for the variable y
[2] 32y = 0
[2] y = 0
// By now we know this much :
x = -4y
y = 0
// Use the y value to solve for x
x = -4(-0/32766) = 0
Solution :
{x,y} = {0,0/32766}

What's Ali's average speed on her walk to school if she walks halfway at 2mph and runs the rest of the way at 7mph?
Answer:
s = 28/9
Step-by-step explanation:
d/(7 x 2) + d/(2 x 2) = d/s
d/14 + d/4 = d/s
18d/56 = d/s
18/56 = 1/s
s = 28/9
The average speed is 28/9.
What is Average speed?Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speed, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.
Example
Using the average speed formula, find the average speed of Sam, who covers the first 200 kilometers in 4 hours and the next 160 kilometers in another 4 hours.
To find the average speed we need the total distance and the total time.
Total distance covered by Sam = 200Km + 160 km = 360 km
Total time taken by Sam = 4 hour + 4 hour = 8 hour
Average Speed = Total distance covered ÷ Total time taken
Average Speed = 360 ÷ 8 = 45km/hr
The average speed of a body is equal to the total distance covered, divided by the total time taken. The formula for average speed is given as:
Average Speed Formula:
Average Speed = Total distance covered ÷ Total time taken
Given:
halfway at 2mph and runs the rest of the way at 7mph
d/(7 x 2) + d/(2 x 2) = d/s
d/14 + d/4 = d/s
18d/56 = d/s
18/56 = 1/s
s = 28/9 mph

Plot and connect the points A (2, -2), B (-4, -4), C (-4, -1), D (-2, 3), E (1, 3), F (2, 5), and find the length of BC.
Answer:
BC = 3 units
Step-by-step explanation:
Given points:
A = (2, -2)B = (-4, -4)C = (-4, -1)D = (-2, 3)E = (1, 3)F = (2, 5)Plot the points on the coordinate plane (x, y) and connect them in alphabetical order with straight lines (see attached).
From visual inspection of the drawn polygon, we can see that the length of BC is 3 units.
It is fairly simple to calculate the length of BC without plotting the points.
As points B and C have the same x-value, this means that the distance between them is simply the difference between their y-values.
⇒ distance = |-4 - (-1)| = |-3| = 3 units

Answer: 5
Step-by-step explanation:
The formula for distance is d = √((x2-x1)2 + (y2-y1)2)
Substitute the x's and the y's for the ordered pairs.

work out the perimeter of this semicircle. take pi to be 3.142
Answer:
P = 25.71 cm
Step-by-step explanation:
Perimeter of semicircle = πD/2
Where D=10 cm
P = (3.142)(10)/2
P = (3.142)(5)
P = 15.71 cm
Complete Perimeter of Semicircle = P + Diameter
= 15.71 + 10
= 25.71 cm
Answer:
25.71cm
Step-by-step explanation:
3.142 x 10 = 31.42
31.42/2 = 15.71 (half of the circumference)
15.71 + 10(the diameter).
= 25.71cm

What is the equation of the line that is parallel to 6x – 2y = 4 + 6y and passes through the point (8, –16)?
A. y=−43x−16/3
B. y=−3/4x−16
C. y=3/4x−22
D. y=4/3x−64/3
Answer:
y=

x−22
Step-by-step explanation:
We are given;
The equation of a line 6x-2y=4+6y
A point (8, -16)
We are required to determine the equation of a line parallel to the given line and passing through the given point.
One way we can determine the equation of a line is when we are given its slope and a point where it is passing through,
First we get the slope of the line from the equation given;
We write the equation in the form y = mx + c, where m is the slope
That is;
6x-2y=4+6y
6y + 2y = 6x-4
8y = 6x -4
We get, y = 3/4 x - 4
Therefore, the slope, m₁ = 3/4
But; for parallel lines m₁=m₂
Therefore, the slope of the line in question, m₂ = 3/4
To get the equation of the line;
We take a point (x, y) and the point (8, -16) together with the slope;
That is;
\frac{(y--16}{x-8}=\frac{3}{4}
x−8
(y−−16
=

\begin{gathered}4(y+16)=3(x-8)\\4y + 64 = 3x - 24\\4y=3x-88\\ y=\frac{3}{4}x-22\end{gathered}
4(y+16)=3(x−8)
4y+64=3x−24
4y=3x−88
y=

But; for parallel lines m₁=m₂
Therefore, the slope of the line in question, m₂ = 3/4

whats the surface area?
Answer:
1108 in²
Step-by-step explanation:
You want the total surface area of the pentagonal prism shown.
Base areaThe area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...
A = LW +1/2bh
A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches
Lateral areaThe lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.
LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches
Total areaThe total surface area of the figure is the sum of the two base areas and the lateral area:
SA = 2(114 in²) +880 in² = 1108 in²
The surface area of the composite figure is 1108 in².

To find an increase of 30% of price P, which expression should you use to find the final price?
A. .70p
B. .30p
C. 1.70p
D. 1.30p
The final price would be 1.3 times the original price P, or 1.3P. This corresponds to option D, 1.30P.
why the option D is correct
To find an increase of 30% of price P, you would need to use the expression:
D. 1.30P
This is because an increase of 30% means adding 30% of the original price P to P. Mathematically, this can be represented as:
P + 0.3P
Simplifying this expression, we get:
1.3P
Therefore, the final price would be 1.3 times the original price P, or 1.3P. This corresponds to option D, 1.30P.
