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

Answer:

2/3

1/2

3/4

1/6

Step-by-step explanation:

Simply multiply each number by one-third.

1 * 1/3 = 1/3

3/4 * 1/3 = 3/12 = 1/4

2 * 1/3 = 2/3

1 1/2 = 3/2 * 1/3 - 3/6 = 1/2

2 1/4 = 9/4 * 1/3 = 9/12 = 3/4

1/2 * 1/3 = 1/6

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

Answer:

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:

In this problem, the distance, in miles, after x hours driving is modeled by:

[tex]y = 73.6 - 67.8x[/tex]

Answer:

Step-by-step explanation:

Given that:

The population mean [tex]\mu[/tex] = 30

The sample size n = 200

The sample-mean [tex]\overline x[/tex] = 27.5

The sample standard deviation s = 18.9

The level of significance ∝ = 0.05

The null hypothesis and the alternative hypothesis can be written as:

[tex]H_o:\mu \ge 30 \\ \\ H_1: \mu < 30[/tex]

Since the alternative hypothesis indicates < sign, then this test is left-tailed

The  t-test statistics is:

[tex]t =\dfrac{\overline x - \mu }{\dfrac{s}{\sqrt{n}}}[/tex]

[tex]t =\dfrac{27.5 -30 }{\dfrac{18.9}{\sqrt{200}}}[/tex]

[tex]t =\dfrac{-2.5}{\dfrac{18.9}{14.142}}[/tex]

t = -1.871

The p-value = P(t< -1.871)

From the standard normal t tables

The p-value = 0.0314

Thus, since the p-value is less than the level of significance ∝ = 0.05, then we reject the null hypothesis.

I dont really know how to explain it but it is a negative correlation.

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.

Richard was faster on Sunday than Saturday.

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.

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.
