Answer:

Step-by-step explanation:
Explain in words how you know this inequality statement is true. Think about where they would be on a number line. 8 1/4 > - 8 1/4
Step-by-step explanation:
8 1/4 > - 8 1/4
when you plot these two numbers on number line
8 1/4 will lie on the right of the zero and - 8 1/4 will be on the left of the zero. The numbers on right of the zero are +ve and numbers on the left of zero are -ve. +ve numbers are always greater than -ve numbers. So 8 1/4 > - 8 1/4
each minute your heart pumps 1.5 gallons of blood around your body. How many pints of blood will your heart pump in a day?
The heart pumps around 17280 pints of blood in a day.
To find out how many pints of blood your heart pumps in a day, we need to determine the total volume of blood that your heart pumps in one day.
We know that your heart pumps 1.5 gallons of blood per minute. To find out how much blood your heart pumps in one day, we need to multiply that amount by the number of minutes in a day.
1 day = 24 hours
1 hour = 60 minutes
So, the number of minutes in one day is 24 hours x 60 minutes = 1440 minutes
Now, we can use this information to find out how many gallons of blood your heart pumps in a day.
Gallons of blood pumped per day = 1.5 gallons/minute x 1440 minutes/day
= 2160 gallons
1 gallon = 8 pints
So the number of pints of blood that your heart pumps in a day = 2160 gallons × 8 pints/gallon = 17280 pints.

statements that are true for a cylinder with radius r and height h.
Doubling r doubles the volume.
Doubling r quadruples the volume.
Doubling h doubles the volume.
Doubling h quadruples the volume.
Doubling h and r quadruples the volume.
Answer:
Only the second and third statements are correct:
Doubling r quadruples the volume.
Doubling h doubles the volume.
Step-by-step explanation:
The volume of a cylinder is given by:
[tex]\displaystyle V=\pi r^2h[/tex]
We can go through each statement and examine its validity.
Statement 1)
If the radius is doubled, our new radius is now 2r. Hence, our volume is:
[tex]\displaystyle V=\pi (2r)^2h=4\pi r^2h[/tex]
So, compared to the old volume, the new volume is quadrupled the original volume.
Statement 1 is not correct.
Statement 2)
Using the previous reasonsing, Statement 2 is correct.
Statement 3)
If the height is doubled, our new height is now 2h. Hence, our volume is:
[tex]V=\pi r^2(2h)=2\pi r^2h[/tex]
So, compared to the old volume, the new volume has been doubled.
Statement 3 is correct.
Statement 4)
Statement 4 is not correct using the previous reasonsing.
Statement 5)
Doubling the radius results in 2r and doubling the height results in 2h. Hence, the new volume is:
[tex]V=\pi (2r)^2(2h)=\pi (4r^2)(2h)=8\pi r^2h[/tex]
So, compared to the old volume, the new volume is increased by eight-fold.
Statement 5 is not correct.

y = - 0.32x² - 1.26x + 15.81
Step-by-step explanation:
From the graph, it can be deduced that the graph isn't linear nor exponential. The graph shown is a quadratic graph. Hence the regression equation which best fits the model is represented in the form :
y = Ax² + Bx + C
Using technology, the regression model obtained by fitting the data is :
y = - 0.32x² - 1.26x + 15.8

4x+5y=-7
-5x-3y=-1
I need help with this question since im not smart
Answer:
To solve this system of equations, you can use the method of elimination. To do this, you can add the two equations together:
4x + 5y - 5x - 3y = -7 - 1
-x + 2y = -8
Then, you can divide both sides of the equation by -1 to solve for y:
x - 2y = 8
y = (x - 8) / 2
Now that you have solved for y, you can substitute this expression back into either of the original equations to solve for x. For example, you can substitute y = (x - 8) / 2 into the first equation to get:
4x + 5((x - 8) / 2) = -7
4x + 5x - 40 = -7
9x = 33
x = 3.67
Now that you have solved for both x and y, you can find the solution to the system of equations:
x = 3.67
y = (3.67 - 8) / 2 = -2.17
So, the solution to the system of equations is x = 3.67 and y = -2.17.

A test for syphilis gives a positive result with probability 0.98 when tested on a person whohas the disease. The test gives a negative result with probability 0.9 when tested on a personwho does not have the disease. Assume that 3% of a society has the disease, and compute thefollowing probabilities in the order they are asked. Note that for each individual there are twodisease status(disease, no disease) and two types of test results(positive, negative).
a) Compute the probability that an individual has the disease and has a positive test result. Explain.
b) Compute the probability that an individual does not have the disease and has a positive test result.
c) What does the sum of two probabilities given above correspond to? Explan.
d) If possible, using the three probabilities computed above compute the probability that an individual with a positive test result has the disease. Give reasons to your computation.
Answer:
a) P₁ = 0,0294
b) P₂ = 0,097
c) P₃ = 0,1264
P₃ is the total probability of the individual having a positive test result
d) P₄ = 0,232
Step-by-step explanation:
a) Probability that an individual has the disease and has a positive result is P₁ :
P₁ = The probability of having the disease * Probability of + in the test result
P₁ = 0,03 * 0,98
P₁ = 0,0294
b) the probability that an individual does not have the disease and has a positive test result P₂ is:
P₂ = 0,97 * 0,1
P₂ = 0,097
c) P₃ the sum of the two previous probabilities is:
P₃ = 0,0294 + 0,097
P₃ = 0,1264
P₃ is the total probability of the individual having a positive test result
d) Applying the Bayes theorem we can get the probability that an individual with a positive test result has the disease. (P₄ )
Bayes theorem establishes:
P [ A/B ] = P[B/A] * P(A) / P(B)
In this case
P[ with disease/ given (+)tr]
= P [(+)Test/ with disease]* P (with disease)/ P of test +
P₄ = 0,98 * 0,03 / 0,1264
P₄ = 0,232
What is the equation of this graph in slope intercept form

y = 3
What is the slope-intercept form of the equation of a line?The slope-intercept form of the equation of a line is; y = m·x + c, where;
m = The slope of the graph
c = The y-intercept of the graph
The equation of the lines in the graphs (blue line, and red line) are found as follows;
The slope of the blue line is found using the points on the graph as follows;
The coordinates of points on the blue line graph are; (0, 4), (2, 4), (4, 4)
The slope is therefore; m = (4 - 4)/(4 - 2) = 0
The y-intercept, obtained from the graph is; c = 4
The value of the slope, m = 0, indicates that the graph is an horizontal line with an equation y = c
c = 4
The equation of the blue line graph in slope-intercept form is therefore;
y = 4
The coordinates of points on the red line graph are; (0, 3), (2, 3), (4, 3)
The slope of the red line graph is therefore;
m = (3 - 3)/(4 - 2) = 0
The y-intercept of the red line graph is; c = 3

Solve systems of equations by elimination -3x-3y=3 3x+6y=9
Answer: x = -5, y = 4
Step-by-step explanation:
Align the two equations according to their terms:
[tex]\left \{ {{-3x-3y = 3} \atop {3x+6y = 9}} \right.[/tex]
Add the two equations. Because -3x and 3x equals zero, they can be eliminated from the equation. This results in:
[tex]3y = 12\\y = 4[/tex]
Plug in y = 4 into the first equation:
[tex]-3x - 3(4) = 3\\[/tex]
Solve for x:
[tex]-3x-12 = 3\\-3x = 15\\x = -5[/tex]
Check by plugging in both x and y:
[tex]-3(-5) - 3(4) = 3\\15 - 12 = 3\\3 = 3[/tex]
So, x = -5 and y = 4
