Write an equation of a line that is perpendicular to y = 4x + 8 and passes through (-8, 4).
y = -1/4x - 7
y = -1/4x + 2
y = 4x + 24
y = 4x + 36
The equation of a line is y=-1/4x-7, (option 1)
What is the equation of a line?A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.
How do you find the equation of a line?Write the equation in the form y = mx + b to find the slope m and the y-intercept. This will allow you to graph the equation using the slope and y-intercept.
Given:-
Equation of the line is y=4x+8
The point through which the line passes (-8,4).
here the slope of the line is m1=4
To find the perpendicular line we know the formula
m1*m2=-1
By putting the value of m1 we get m2= -1/4
By using the one-point formula of the line we have
=>(y-y1)=m2*(x-x1)
By putting the values of y1 and x1 we get
(y1,x1)=(-8,4)
=>(y+8)=-0.25*(x-4)
y+0.25x+7=0
Hence the desired equation of the line is y=-1/4x-7

The figure shows right triangle MPR on the coordinate plane. Line segment MQ is
a median of the triangle.
What are the coordinates of point Q? Explain your answer. Using the information in the figure, show that the length of the median MQ is half the length of the hypotenuse of MRP. Provide an argument supported by valid mathematical
reasoning and/or calculations.
Answer:
see explanation
Step-by-step explanation:
the median is a segment that goes from the vertex of a triangle to the midpoint of the opposite side.
Then Q is the midpoint of PR
given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint M is
M = ( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ) ← midpoint formula
use this formula to find the coordinates of Q
with (x₁, y₁ ) = R (0, 2b ) and (x₂, y₂ ) = P (2a, 0 )
Q = ( [tex]\frac{0+2a}{2}[/tex] , [tex]\frac{2b+0}{2}[/tex] ) = ( [tex]\frac{2a}{2}[/tex] , [tex]\frac{2b}{2}[/tex] ) = (a, b )
---------------------------------------------------
use the distance formula to find the lengths of median MQ and hypotenuse PR of Δ MRP
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = M (0, 0 ) and (x₂, y₂ ) = Q (a, b )
MQ = [tex]\sqrt{(a-0)^2+(b-0)^2}[/tex] = [tex]\sqrt{a^2+b^2}[/tex]
repeat with (x₁, y₁ ) = P (2a, 0 ) and (x₂, y₂ ) = R (0, 2b )
PR = [tex]\sqrt{(0-2a)^2+(2b-0)^2}[/tex]
= [tex]\sqrt{(-2a)^2+(2b)^2}[/tex]
= [tex]\sqrt{4a^2+4b^2}[/tex]
= [tex]\sqrt{4(a^2+b^2)}[/tex]
= 2[tex]\sqrt{a^2+b^2}[/tex]
then MQ is half PR

Suppose that the mean GRE score for the United States is 500 and the standard deviation is 75. Use the 68-95-99.7 (empirical) rule to determine the percentage of students likely to get a score below 275? Is a score below 275 significantly different from the mean
1) The percentage of students who will get a score below 275 is; 0.15%
2) Yes, any score below 275 is significantly different from the mean.
How to use the Empirical rule in statistics?
The empirical rule states that for a normal distribution, 68% of the distribution are within one standard deviation from the mean, 95% are within two standard deviation from the mean and 99.7% are within three standard deviations from the mean.
The formula for z-score is;
z = (x' - μ)/σ
where;
x' is sample mean
μ is population mean
σ is standard deviation
1) We are given;
Population mean; μ = 500
Sample mean; x' = 275
standard deviation; σ = 75
Thus;
z = (275 - 500)/75
z = -3
This is 3 standard deviations from the mean. Thus;
The percentage of students who will get a score below 275 is;
(100 - 99.7)/2 = 0.15%
2) Yes, any score below 275 is more than 3 standard deviations away from the mean and can be considered significantly different from the mean.

A company hired 20 new graduates. The mean salary of the newly hired employees is 38 in thousands of dollars, where Σ(x - 38)² = 64. Which is the population variance of the given data ?
The population variance of the given data is 3.2.
Given Σ(x - 38)² = 64 .
We know that the population variance of the data is the square of the standard deviation.
Now the standard deviation for the population is given by
σ =√(Σ(x - 38)² / N)
Again variance = σ ²
Let us first calculate σ .
σ = √(64/20) = √3.2
variance
= σ ²
= (√3.2)²
= 3.2
Therefore the variance of the population is 3.2
In probability theory and statistics, variance is the predicted squared variation of a random variable from its population mean or sample mean. Dispersion, or how far apart from the mean a set of data are from one another, is measured by variance.
A few ideas that use variance include descriptive statistics, statistical inference, hypothesis testing, goodness of fit, and Monte Carlo sampling.

Step-by-step explanation:
The Pool Fun Company has learned that, by pricing a newly released Fun Noodle at $5, sales will reach 7000 Fun Noodles per day during the summer. Raising the price to $6 will cause the sales to fall to 3000 Fun Noodles per day.
Assume that the relationship between sales price, x, and the number of Fun Noodles sold, y, is linear. Use ordered pairs of the form (sales price, number sold).
1. Write an equation in a slope-intercept form describing this relationship.
2. Predict the daily sales of Fun Noodles if the price is $5.50
1. The equation in a slope-intercept form describing the relationship is y = -4000x + 27000.
2. The daily sales of Fun Noodles at the price of $5.50 is 5000.
How to represent linear equation in slope intercept form?The Pool Fun Company has learned that, by pricing a newly released Fun Noodle at $5, sales will reach 7000 Fun Noodles per day during the summer. Raising the price to $6 will cause the sales to fall to 3000 Fun Noodles per day.
The relationship between sales price, x, and the number of Fun Noodles sold, y, is linear. The ordered pair are (5, 7000) and (6, 3000).
The equation in slope intercept form describing the relationship is as follows:
1. y = mx + b
where
m = slopeb = y-interceptTherefore,
m = 3000 - 7000 / 6 - 5
m = - 4000
Let's find the y-intercept using (6, 3000)
3000 = -4000(6) + b
3000 + 24000 = b
27000 = b
Hence, the equation is y = -4000x + 27000
2. The daily sales of Fun Noodles at the price of $5.50 can be computed as follows;
y = -4000(5.5) + 27000
y = -22000 + 27000
y = 5000
Therefore, the daily sales is 5000.
