A truck driver travels from a distributor to a retailer every week. The driver records the distance that he is from the retailer at different times during his trip. After several weeks of collecting data, the driver creates a scatter plot of the data. The best-fit line is Y=73.6 - 67.8x where x is the number of hours spent driving and y is the distance, in miles, from the retailer. Which of the following statements are true? Select all that apply. A. The distance from the retailer increases with time. B. The distance from the retailer decreases with time. C. The distributor is 67.8 miles away from the retailer. D. The distributor is 73.6 miles away from the retailer. E. The truck is traveling at a rate of 67,8 miles per hour. 1 1 1 ED 1 1 1 1
Answer:
Options (B), (D), and (E) are correct.
Step-by-step explanation:
The given best fit curve for the collected data is
[tex]y=73.6 - 67.8x\cdots(i)[/tex]
Where x is the number of hours spent driving and y is the distance of distributer, in miles, from the retailer.
As the driver starts recording the time when he starts from the retailer, so at the starting time, x=0, the driver is at the retailer.
So, putting x=0 in the given equation (i) to get the distance between the distributor and retailer, we have
[tex]y =73.6 - 67.8\times 0[/tex]
[tex]\Rightarrow y= 73.6[/tex] miles.
So, the distributor is 73.6 miles away from the retailer.
From equation (i), as x (time) increases the value of y (distance) decreases.
So, The distance from the retailer decreases with time.
Now, obtaining the rate of change the distance,y, from quation (i), with respect to time,x, to get the speed of the truck, we have
[tex]\frac {dy}{dx}=-67.8[/tex] mile/hour
Negative sign shows that the distance is decreasing, taking the magnitude of the rate of change of distance with respect to time to get the speed,
speed [tex]= | dy/dx |= | -67.8 | = 67.8[/tex] miles/hour
So, the speed of the truck is 67.8 miles per hour.
Hence, options (B), (D), and (E) are correct.
Using linear function concepts, it is found that the correct options are:
B. The distance from the retailer decreases with time.
D. The distributor is 73.6 miles away from the retailer.
E. The truck is traveling at a rate of 67,8 miles per hour
A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change. b is the y-intercept, which is the initial value.In this problem, the distance, in miles, after x hours driving is modeled by:
[tex]y = 73.6 - 67.8x[/tex]
The slope is [tex]m = -67.8[/tex], which means that the distance decreases with time, and the truck is traveling at a rate of 67.8 miles per hour, hence options B and E are correct.The y-intercept is of [tex]b = 73.6[/tex], which means that the initial distance is of 73.6 miles, hence option D is correct.A similar problem is given at https://brainly.com/question/24808124

3x+5=2x+7. Find X to complete the equation
Answer:
x = 2
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
3x+5=2x+7 this is the original equation
since we have no clue as to what x could be, we just take a guess.
lets say we used 3.
we would plug in 3 where the x's are and get
3(3)+5=2(3)=7
three times three is 9, 9 plus 5 is 14.
2 times 3 is 6, 6 plus 7 is 13.
since these numbers do not match, 3 cannot be the answer.
if you did these same steps with the number two, you would get 11 as the answer for both, therefore, x=2
3(2)+5 2(2)+7
6 +5=11 4+7=11

Richard went kayaking last weekend. On Saturday, he kayaked for 2 hours and went 7 kilometers. On Sunday, he kayaked on a different river for 3 hours and went 12 kilometers. On which day did Richard kayak at a faster average speed?
Richard was faster on Sunday than Saturday.
What is average speed?The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity. It is represented by the magnitude and does not have direction.
The formula for average speed is found by calculating the ratio of the total distance traveled by the body to the time taken to cover that distance.
Average Speed = Total Distance traveled/Total Time taken
The average speed equation is articulated as:
Given,
Richard on Saturday,
kayaked distance = 7kms.
Time taken = 2 hours
Speed = Distance/ Time
Speed on Saturday = 7/2
Speed on Saturday = 3.5 km/hr.
Richard on Sunday,
kayaked distance = 12kms.
Time taken = 3 hours
Speed = Distance/ Time
Speed on Sunday = 12/3
Speed on Sunday = 4 km/hr.
Hence, by the above calculation Richard was 0.5 km/hr. faster on Sunday than Saturday.

9514 1404 393
Answer:
positive correlation
Step-by-step explanation:
The general trend of the data is upward to the right, so the trend line has a positive slope. The sign of the correlation matches the sign of the slope of the trend line. The correlation is positive.
__
The data is well-scattered about that "trend line," so the correlation would be only slightly positive.

Answer:
208
Step-by-step explanation:
First of all, it is useful to draw the factory location and the path the truck takes.
If you're paying attention, you will notice that the distance from each marked location to the origin is 3 grid squares horizontally and 4 grid squares vertically. This makes the distance to the origin be the hypotenuse of a 3-4-5 triangle, or 5 grid squares.
Then the distance diagonally from the warehouse to the airport is 10 grid squares. The distance horizontally from the airport to the factory is 6 grid squares, for a total distance of 10+6 = 16 grid squares.
You will notice the grid squares are marked as 13 miles each. The miles driven by the truck are ...
(13 miles)(16) = 208 miles
_____
As you can see, it is helpful to notice when problems make use of 3-4-5 triangles.
If you want to compute this more or less directly, you can recognize the horizontal distance from warehouse to airport is 78 miles, and the vertical distance is 104 miles. The Pythagorean theorem tells you the diagonal distance is ...
WA = √(78² +104²) = √16900 = 130
The distance to the factory is 78 miles, so the total is ...
130 +78 = 208 . . . miles the truck drives

The function p(x) = −2000x2 + 18000x − 15000 models the monthly profit P of a smoothie company, where x represents the price per smoothie. Identify the price range that will generate a monthly profit of at least $25,000. a. Between $4 and $5; inclusive b. Less than $4 c. Between $4 and $5; exclusive d. More than $5
Answer:
Step-by-step explanation:
Givem the profit function
p(x) = −2000x2 + 18000x − 15000
We are to generate the price range that will generate a monthly profit of at least $25,000
Substitute into the function we have;
25000 = −2000x2 + 18000x − 15000
Divide through by 1000
25 = -2x²+18x-15
Rearrange
-2x²+18x-15-25 = 0
2x²-18x+40 = 0
Divide through by 2
x²-9x+20 = 0
Factorize
x²-5x-4x+20 = 0
x(x-5)-4(x-5) = 0
x-4 = 0 and x-5 = 0
x = 4 and x = 5
Hence the price range that will generate a monthly profit of at least $25,000 is between $4 and $5 inclusive

Ruby is decorating for a party and needs 120 meters of ribbon. At the party supply store, the ribbon is sold in rolls. Each roll contains 25 feet of ribbon. How many rolls will Ruby need to purchase? (1 meter is approximately 39.37 inches)
A. 16 rolls
B. 14 rolls
C. 12 rolls
D. 10 rolls
Answer:
A. 16 rolls
Step-by-step explanation:
First, convert 120 meters to inches.
120 meters X 39.37 inches = 4724.4 inches
Then convert the 4724.4 inches into feet.
4724.4/12 = 393.7 feet
Therefore, she needs approximately 383.7 feet.
To get the number of rolls, divide 383.7 by 25 since each roll has 25 feet of ribbon.
383.7/25 = 15.748
15.748 can be rounded up to 16 rolls.
Use any pair of points to calculate the slope of the line.
