Write the equation of the line if the line passes through (4,4) and the y-intercept is -4.
•y = 2x - 4
•y = 2x - 2
•None of these answers are correct.
•y = 8x + 4
•y = 2x + 4
Answers
Answer:
y = 2*x - 4
Step-by-step explanation:
The general equation for a line is:
y = a*x + b
Where a is the slope and b is the y-intercept.
In this case, we know that the line passes through (4, 4) and the y-intercept is -4.
Then:
b = -4
So our line is something like:
y = a*x - 4
Now, we know that the line passes through (4, 4), which means that when x = 4, y = 4.
If we replace these values in the equation, we get:
4 = a*4 - 4
Now we can solve this for a.
4 = a*4 - 4
4 + 4 = a*4
8 = a*4
8/4 = a = 2
Then the equation for the line is:
y = 2*x - 4

38. The number of bottles a machine fills is proportional to the number of minutes the
machine operates. The machine fills 250 bottles every 20 minutes. Create a graph that
shows the number of bottles, y, the machine fills in x minutes.
Answers
Answer:
250/20 = 12.5/min
2 min = 25 bottles
The machine fills 25 bottles every two minutes. So you should make points (minutes, bottles) at (0,0), (2,25), (4,50), (6,75), (8,100), (10,125) and draw a line connecting them.

A lab technician is tested for her consistency by making multiple measurements of the cholesterol level in one blood sample. The target precision is a standard deviation of 1.1 mg/dL or less. If 20 measurements are taken and the standard deviation is 1.6 mg/dL, is there enough evidence to support the claim that her standard deviation is greater than the target, at α = 0.01?
Answers
Answer:
We Do not have enough evidence
Step-by-step explanation:
H0 : σ² ≤ 1.1
H0 : σ² > 1.1
The test statistic (X²) :
χ² = [(n - 1) × s²] ÷ σ²
n = sample size, = 20
s² = 1.6
σ² = 1.1
α = 0.01
χ² = (19 * 1.6) / 1.1
χ² = 27.64
Pvalue :
Using the Pvalue from Chisquare score calculator ; χ² = 27.64 ; df = 19
Pvalue = 0.091
If Pvalue < α ; Reject H0
0.091 > 0.01
Hence, Pvalue > α ; Thus we fail to reject H0.
We thus conclude that, we do not have enough evidence to support the claim that her standard deviation is greater than the target.

Step-by-step explanation:
1. formula: v=(r*pi)*h
v=(6^2*3.14)*4
v=(36*3.14)*4
v=113.04*4
v=452.16
2. formula: v=(r*pi)*h
because you were given the diameter for number 2 you would have to do 10/2 to find the radius. so 5
now plug it into you're equation.
v=(5^2*3.14)*11
v=(25*3.14)*11
v=78.5*11
v=863.5
3. formula: v=(r*pi)*h
v=(7^2*3.14)*10
v=(49*3.14)*10
v=153.86*10
v=153.86

A carton of milk in the shape of a rectangular prism has a leak. The dimensions of the carton are 8 inches by 4 inches by 3 inches. If the rate in which the milk is leaking is 6 cubic inches per minute, how long would it take for the milk carton to completely empty?
Answers
Volume of a rectangular prism = length x width x height.
Volume of milk carton = 8 x 4 x 3 = 96 cubic inches.
Divide the volume by the leak rate:
96/ 6 = 16

It is given that
A photographer needs a frame for a 16 x 20 inch picture
total area is 340 sq. in
width of the frame =?
Let width of the frame be x
The frame is in the shape of a Rectangle
Side of the frame = ( 16+2x) and (20 +2x)
Area of a frame = Total Area - Area of the picture
Total Area = ( 16+2x) (20 +2x)
( 16+2x) (20 +2x) = 340
320 + 72x +4x² = 340
72x +4x²= 20
4x² + 72x = 20

Solve the system of linear equations by substitution.
x-2y=6
3x-5y=11
Answers
Answer:
x = -8, y = -7
Step-by-step explanation:
=> x = 6 + 2y
substitute x = 6 + 2y into the equation 3x - 5y = 11 to solve for y:
=> 3(6 + 2y) - 5y = 11
=> 18 + 6y -5y = 11
=> y = -7
substitute y = -7 into the equation x - 2y = 6 to solve for x:
=> x - 2(-7) = 6
=> x +14 = 6
=> x = -8

Use cubic regression to find a function that fits the following points (1,4),(2,9),(3,34),(-2,-11)
Answers
Answer:
The cubic regression that fits the given set of points is [tex]y = 2\cdot x^{3}-2\cdot x^{2} -3\cdot x + 7[/tex].
Step-by-step explanation:
Let the cubic regression be represented by the following third order polynomial:
[tex]y = a\cdot x^{3}+b\cdot x^{2}+c\cdot x + d[/tex] (1)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]a,b,c,d[/tex] - Coefficients.
By Algebra, we can determine analytically the values of all coefficients by knowing four distinct points. If we know that [tex](x_{1}, y_{1}) = (1,4)[/tex], [tex](x_{2},y_{2}) = (2,9)[/tex], [tex](x_{3}, y_{3}) = (3, 34)[/tex] and [tex](x_{4}, y_{4}) = (-2, -11)[/tex], then the system of linear equations is:
[tex]a+b+c+d = 4[/tex] (1)
[tex]8\cdot a + 4\cdot b + 2\cdot c + d = 9[/tex] (2)
[tex]27\cdot a + 9\cdot b + 3\cdot c + d = 34[/tex] (3)
[tex]-8\cdot a + 4\cdot b -2\cdot c + d = -11[/tex] (4)
The solution of the system of linear equations is: [tex]a = 2[/tex], [tex]b = -2[/tex], [tex]c = -3[/tex], [tex]d = 7[/tex]
The cubic regression that fits the given set of points is [tex]y = 2\cdot x^{3}-2\cdot x^{2} -3\cdot x + 7[/tex].
