A student finds the sum of the angle measures in an octagon by multiplying 7 • 180°. What is the student's error?
The student should compute 6*180 = 1080 because of the formula
S = 180(n-2)
We have n = 8 sides which leads the n-2 part to become n-2 = 8-2 = 6

explanation:
original coordinates of C: (0, -7)If reflected over y axis, there will be additive inverse in x unit
use the formula: (x,y) → (−x, y)
new coordinates: (0, -7)Then if translated vertically, there will be change in y axis:
(0, -7+4) → (0, -3)
what is the value of x
Answer:
x = 20
Step-by-step explanation:
given a line parallel to a side of a triangle and intersecting the other two sides, then it divides those sides proportionally , that is
[tex]\frac{10}{5x+10}[/tex] = [tex]\frac{11}{121}[/tex] = [tex]\frac{1}{11}[/tex] ( cross- multiply )
5x + 10 = 110 ( subtract 10 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20

Write the equation of a line that is perpendicular to y = -3 + 6 and that passes through the point
(2,-6).
Answer:
Perpendicular lines are lines that are at right angles to each other.
For perpendicular lines, the product of their slopes is -1.
[tex]\implies m_2=\dfrac{-1}{m_1}[/tex]
(where [tex]m_1[/tex] and [tex]m_2[/tex] are the slopes of perpendicular lines)
The slope of the given equation is -3. Therefore, to find the slope of the line that is perpendicular:
[tex]m_2=\dfrac{-1}{-3}=\dfrac13[/tex]
Now we have the slope, we can use the point-slope form of a linear equation with [tex]m=\dfrac13[/tex] and [tex](x_1,y_1)=(2,-6)[/tex] to find the equation of the perpendicular line:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-(-6)=\dfrac13(x-2)[/tex]
[tex]\implies y+6=\dfrac13x-\dfrac23[/tex]
[tex]\implies y=\dfrac13x-\dfrac{20}3[/tex]

Wendy asked 40 students on the school football team if they ever injured themselves while playing sports. Fifteen football team members responded “Yes.” Wendy concluded that 375 of the 1,000 students in her school have injured themselves playing sports. Select whether Wendy's conclusion is valid or invalid.
Answer:
Yes, Wendy's conclusion is valid.
Step-by-step explanation:
40 divided by 15= 2.666666666666667
Therefore, 1000 divided by 2.666666666666667= 374.999999999999953 which can be rounded to 375

What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
In the diagram, quadrilateral HIJK is inscribed in circle L.
Now, We know that;
sum of opposite angle are 180 degree.
Hence, We get;
∠H + ∠J = 180
67 + (y - 75) = 180
y - 8 = 180
y = 180 + 8
y = 188
And, We get;
∠I + ∠K = 180°
96 + (x + 83) = 180
x + 179 = 180
x = 180 - 179
x = 1
Thus, The value of variables x and y are,
x = 1 and y = 188

[tex]s=\sqrt{\dfrac{(x_1-\overline x)^2(x_2-\overline x)^2...(x_n-\overline x)^2}{n-1}}[/tex]
What is variance and standard deviation?The variance of the data is the measure of average level by which every point is differed from the mean.
It can be calculated as,
[tex]s^2=\dfrac{(x_1-\overline x)^2(x_2-\overline x)^2...(x_n-\overline x)^2}{n-1}[/tex]
The standard deviation of the data is the half of the difference of the highest value and mean of the data set.
