The graph shows the volume of water in a sink, x minutes after the faucet is turned on.
What is the slope of the line?
Slope =
Part B
Connor says that the graph shows that water is flowing at a rate of 2 gallons per minute. Is he correct?
a. Connor is correct because the rate of water flowing is equal to the slope. Water is flowing in at a rate which is about 2 gallons per minute.
b. Connor is not correct because the rate of water flowing is greater than the slope. Water is flowing in at a rate which is slower than 2 gallons per minute.
c. Connor is not correct because the rate of water flowing is not equal to the slope. Water is flowing in at a rate which is slower than 2 gallons per minute.
d. Connor is correct because the rate of water flowing is less than the slope. Water is flowing in at a rate which is faster than 2 gallons per minute.
Answers
Answer:
Part A: ½
Part B: c. Connor is not correct because the rate of water flowing is not equal to the slope. Water is flowing in at a rate which is slower than 2 gallons per minute.
Step-by-step explanation:
Part A:
Slope of the proportional graph = y/x
Using the point on the line, (4, 2),
Slope = 2/4 = ½.
Part B:
Since the slope of the graph bus ½, it shows that the water is flowing at a rate of ½ gallon per minute. Therefore, Connor is NOT CORRECT.
The rate of water Connor stated does not correspond with the rate shown by the slope. The slope of the graph, ½, shows that the water is flowing at a much slower rate than at the rate of 2 gallons per minute, which Connor stated.
The right answer is C.

15 POINT QUESTION; I REALLY NEED HELP
A dietician gathered data about the amounts of flour, baking powder, and butter used for several different muffin recipes. She used a graphing tool to organize the data in different scatter plots and found the following lines of best fit:
The relationship between the baking powder used, x, and the flour used, y, is modeled by the equation y = 0.13x + 0.92, and the correlation coefficient for the data is 0.953.
The relationship between the baking powder used, x, and the butter used, y, is modeled by the equation y = 0.24x + 0.76, and the correlation coefficient for the data is 0.802.
The relationship between the flour used, x, and the butter used, y, is modeled by the equation y = 0.86x + 0.52, and the correlation coefficient for the data is 0.693. Which line of best fit can the dietician expect to produce the most reliable predictions?
A. the line modeling the baking powder and the butter used
B. the line modeling the baking powder and the flour used
C. the line modeling the flour and the butter used
D. All three lines will give equally reliable predictions.

Answer:

Step-by-step explanation:
plato master test
On comparing the pairwise R - squared value between the three variables, we find that the line modeling the baking powder and the flour used can be expected to produce the most reliable predictions.
What is R - squared value ?R-Squared value is a quantifiable analysis of how well the line of best fit (linear regression model) fits your data. A value closer to 1 (100%) is usually good.
The coefficient of determination - R - squared value is square of the correlation coefficient.
R - squared value of the relationship between baking powder and flour used = 0.953² = 0.908
R - squared value of the relationship between baking powder and butter used = 0.802² = 0.643
R - squared value of the relationship between flour and butter used = 0.693² = 0.48
Since, on comparing the R - squared values of the three relationships, we find that the R - squared value of the relationship between baking powder and flour used is largest. Thus, line of best fit between baking powder and flour is expected to produce the most reliable predictions.

Answer:
x = 0, 2, 5/2 ± 1/2i
Step-by-step explanation:
I'm not really sure what the question is asking but I'm going to assume you want to find the zeroes of the function.
0 = 2x^4 - 14x^3 + 33x^2 - 26x
~Factor
0 = x(x - 2)(2x² - 10x + 13)
~Set factors to equal 0 and solve
x - 2 = 0
x = 2
2x² - 10x + 13 = 0

7. The graph of the linear function is shown on the coordinate grid below.
Answers
Answer: C . The slope is -4/3 and the y-intercept is 4.
Step-by-step explanation:
Using the two given points, we will use them to evaluate the slope and the y intercept.
(-1.5,6)
( 4.5,-2)
To find the slope we will find the difference in the y coordinates of the points and divide it by the difference in the x coordinates of the point.
6-(-2) = 8
-1.5 - 4.5 = -6
Slope : 8/-6= -4/3.
Since the slope is -4/3, we will use the formula y= mx + b to find the y intercept. In the formula y= mx + b, the slope is m and b is the y intercept.
Use one of the given points, and input its x and y values into the formula including the slope to solve for b(the y-intercept).
We will use the point, ( -1.5,6)
6 = -4/3(-1.5) + b
6 = 2 + b
-2 -2
b = 4.
b is indeed equal to 4 because it even indicates on the graph that the y intercept is 4 which is where x is equal to 0.
Solve for x.
