(0.5, 3)
(−0.5, 3)
(0.5, 1)
A.(−0.5, 3) and (0.5, 1) would provide the most accurate estimation. The slope of the line drawn between these two points appears closest to the slope of the function at x=0.
B.(−0.5, 2) and (0.5, 3) would provide the most accurate estimation. The slope of the line drawn between these two points appears closest to the opposite of the slope of the function at x=0.
C.(−0.5, 2) and (0.5, 3) would provide the most accurate estimation. The slope of the line drawn between these two points appears closest to the slope of the function at x=0.
D.(−0.5, 3) and (0.5, 1) would provide the most accurate estimation. The slope of the line drawn between these two points appears closest to the opposite of the slope of the function at x=0.
Answer:
2. B. The rate of change is 2
3. C. The rate of change is 2 inches per hour
4. B. The rate of change is 1.25 degrees Fahrenheit per day
5. (-0.5, 3) and (0.5, 3) would provide the most accurate estimation. The slope of the line drawn between these two points appears closest to the slope of the function at x = 0
Step-by-step explanation:
2. Using the points (-1, -1) and the (1, 3) we have;
The rate of change = (Change in the y-values)/(Corresponding change in the x-values)
The rate of change = (3 - (-1))/(1 - (-1)) = 4/2 = 2
The rate of change is 2
3. Using the points (0, 0) and the (5, 10) we have;
The rate of change = (Change in the y-values)/(Corresponding change in the x-values)
Given that the function is a linear function, the rate of change of the function at 3 hours is given by the slope, m, as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where;
(x₁, y₁) = (0, 0)
(x₂, y₂) = (5, 10)
The y-coordinate being the inches of snow, and the x-coordinate being the time in hours, we have;
The rate of change = (10 - 0)/(5 - 0) = 10/5 = 2
The rate of change is 2 inches per hour
4. Given that the function is a linear function, the rate of change of the function at ninth day is given by the slope, m, as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where;
(x₁, y₁) = (2, 55)
(x₂, y₂) = (10, 65)
The y-coordinate being the temperature in degrees, and the x-coordinate being the time in days, we have;
[tex]Slope, \, m =\dfrac{65-55}{10-2} = \dfrac{10}{8} = 1.25[/tex]
The rate of change is 1.25 degrees Fahrenheit per day
5. The points on the graph of the function that come before and after the point where the graph of the function crosses y-axis (the y-intercept) and are close to point are (-0.5, 2) and (0.5, 3)
Therefore, (-0.5, 2) and (0.5, 3) would provide the most accurate estimation. The slope of the line drawn between these two points appears closest to the slope of the function at x = 0.

Write a formula that will help Greg determine
how much money he will earn in one week.
Let's let
a = total amount earned
h = hours worked in one week
b = number of bushels picked
Use the curved parentheses 'O', if required.
Do not use other parentheses like '{ }' or '[ ]'.
Answer:
a = 3h + 2.50b
Step-by-step explanation:
Greg picks apples to make money over the summer. He earns $3 an hour plus $2.50 for each bushel he picks. Write a formula that will help Greg determine how much money he will earn in one week.
Let
a = Total amount earned
h = Hours worked in one week
b = Number of bushels picked
Solution:
Amount earned per hour = $3
Amount earned per bushel picked = $2.50
Total amount earned = (Amount earned per hour) ( Hours worked in one week) + (Amount earned per bushel picked) (Number of bushels picked)
a = 3*h + 2.50*b
= 3h + 2.50b
a = 3h + 2.50b

Answer:
R: (Y| E R {-4<=y<=-1})
Step-by-step explanation:
Just look at where the graph is limited to vertically, in this case -1 and -4.
The range of the given graph is [-4,-1] and this can be determined by observing the given graph.
The following steps can be used in order to determine the range of the given graph:
Step 1 - The range is the different values of 'y' at different values of 'x'.
Step 2 - According to the given graph, the maximum value of 'y' is -1.
Step 3 - According to the given graph, the minimum value of 'y' is -4.
Step 4 - So, the range of the given graph is given below:

Question 4 (1 point) Phil Dunphy, a real estate agent, is considering whether he should list an unusual $345,584 house for sale. If he lists it, he will need to spend $5,892 in advertising, staging, and fresh cookies. The current owner has given Phil 6 months to sell the house. If he sells it, he will receive a commission of $19,166. If he is unable to sell the house, he will lose the listing and his expenses. Phil estimates the probability of selling this house in 6 months to be 33%. What is the expected profit on this listing? Your Answer:
Answers:
The expected profit on the listing is $2377.14
Step-by-step explanation:
Given that:
The probability of selling the house in 6 months is p = 0.33
The probability of not selling the house = 1 - 0.33 = 0.67
Suppose X represents the profit on the listing;
Then: we can compute the expected profit on the listing as:
E(X) = ($19166 × 0.33) - ($5892 × 0.67)
E(X) = $6324.78 - $3947.64
E(X) = $2377.14
Thus, the expected profit on the listing is $2377.14

On Tuesday, the temperature in Fairfield, Montana fell from 51℉ at noon to −℉ at midnight.What was the average temperature change per hour?
Help!! I don't get this
Answer:
55
Step-by-step explanation:
No matter what happens in between, the average rate of change between 2 points of any interval is the slope of the 2 points of the interval.
The 2 points are (-8, -50) and (-6, 60), and we need to find the slope (which, as a reminder, is change in x over change in y):
(60-(-50))/(-6-(-8)) = (110)/(2)=55
Therefore, the average rate of change between the interval -8≤x≤-6 is 55.
One out of every 119 tax returns that a tax auditor examines requires an audit. Find the probability that (a) the first return requiring an audit is the 25th return the tax auditor examines, (b) the first return requiring an audit is the first or second return the tax auditor examines, and (c) none of the first five returns the tax auditor examines require an audit.
Answer:
A) 0.00686
B) 0.01673
C) 0.99587
Step-by-step explanation:
For this question, we are interested in the first success and we will Thus make use of geometric probability distribution.
It goes by the formula;
P(x) = [(1 - p)^(x - 1)]p
We are told that One out of every 119 tax returns that a tax auditor examines requires an audit.
Thus; p = 1/119 = 0.0084
A) Probability that the first return requiring an audit is the 25th return the tax auditor examines is given by;
P(25) = [(1 - 0.0084)^(25 - 1)]0.0084
P(25) = 0.00686
B) Probability the first requiring an audit is the first or second return the tax auditor examines, is;
P(1 or 2) = P(1) + P(2)
P(1) = [(1 - 0.0084)^(1 - 1)]0.0084
P(1) = 0.0084
P(2) = [(1 - 0.0084)^(2 - 1)]0.0084
P(2) = 0.00833
Thus;
P(1 or 2) = 0.0084 + 0.00833
P(1 or 2) = 0.01673
C) Probability that none of the first five returns the tax auditor examines require an audit is given by;
P(X > 5) = 1 - P(X ≤ 5)
Now,
P(X ≤ 5) is expressed as;
P(X ≤ 5) = P(1) + P(2) + P(3) + P(4) + P(5)
We know P(1) & P(2) already. Let's find P(3), P(4) and P(5)
P(3) = [(1 - 0.0084)^(3 - 1)]0.0084
P(3) = 0.00826
P(4) = [(1 - 0.0084)^(4 - 1)]0.0084
P(4) = 0.00819
P(5) = [(1 - 0.0084)^(5 - 1)]0.0084
P(5) = 0.00812
P(X ≤ 5) = 0.0084 + 0.00833 + 0.00826 + 0.00819 + 0.00812
P(X ≤ 5) = 0.00413
P(X > 5) = 1 - 0.00413
P(X > 5) = 0.99587

Let x be the number of invitations and y be the price of the printing job. The point-slope form of an equation that models the situation is
Answer:
p1: y-100=1.6(x-25)
p2 y=1.6x+60
p3 slope; 1.60
p4 y intercept, slope intercept form, easier to fine using slope intercept
Step-by-step explanation:
this was for savvas 2.2 practice
The required point slope of the equation is y-100=1.6(x-25) and the slope-intercept equation y = 1.6x + 60 and the slope represents the cost per invitation.
Given that,
The total price of a printing job at Incredible Invites includes the cost per invitation plus a one-time set-up fee. Write equations in point-slope and slope-intercept forms to model the situation. What part of the equations represents the cost per invitation is to be determined.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
Let the number of invitations be x, and the total cost be y.
Slope-point form of the equation is given by,
(y - y₁) = (y₂ - y₁)/ (x₂ - x₁ ) (x - x₁)
substitute value in the equation,
y - 100 = (140 - 100)/ (50 - 25)(x - 25)
y - 100 = 40 / 25 (x - 25)
y - 100 = 1.6 (x - 25) - - - - - - (point-slope form)
y = 1.6x - 25 * 1.6 + 100
y = 1.6x - 40 + 100
y = 1.6x + 60 - - - - - (slope-intercept form)
Slope = 1.6
Thus, the required point slope of the equation is y-100=1.6(x-25), and the slope-intercept equation y = 1.6x + 60, and the slope represents the cost per invitation.
