Mr. Waxman is helping with deliveries for a shipping company. The graph shows a linear model for his delivery times on different days.

(A) Identify two points on the line and write the coordinate pairs below.

(B) Use your two points to find the slope, and make sure to show your work.

(C) Use your slope from Part B and find the equation of the line in point-slope form. Show your work and work through the steps to transform the equation from point-slope form into slope-intercept form.

(D) Based on the equation you found in Part C, predict how long it take Mr. Waxman to deliver his packages on Day 0. Approximately how much did his delivery time decrease per day?

Answers

Answer: a- (7,7) (4,19) b- m=-12/3=-4/1=-4 c- y=4x+35 d- 48min, it increases by 12min a day

Step-by-step explanation:

i did the assignment

Mr. Waxman's delivery is an illustration of a linear function.

(a) Two points on the graph

The points are: (4,19) and (6,11)

(b) The slope of the graph

The slope (m) is calculated as:

[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]

So, we have:

[tex]\mathbf{m = \frac{11 - 19}{6- 4}}[/tex]

[tex]\mathbf{m = \frac{-8}{2}}[/tex]

[tex]\mathbf{m = -4}[/tex]

The slope of the graph is -4

In point-slope form, we have:

[tex]\mathbf{y -y_1 = m(x - x_1)}[/tex]

So, we have:

[tex]\mathbf{y -4 = -4(x -19)}[/tex]

In slope intercept form, we have:

[tex]\mathbf{y = -4(x -19) + 4}[/tex]

Open brackets

[tex]\mathbf{y = -4x +76 + 4}[/tex]

[tex]\mathbf{y = -4x +80}[/tex]

The equation of the graph is: [tex]\mathbf{y = -4x +80}[/tex]

(d) The value of the function at day 0

This means that x = 0

So, we have:

[tex]\mathbf{y = -4(0) +80}[/tex]

[tex]\mathbf{y = 0 +80}[/tex]

[tex]\mathbf{y = 80}[/tex]

Hence, it will take 80 minutes to deliver the package on day 0

Answers

Answer:

645/100 = 129/20 or 6.45

645/50 = 129/10 or 12.9

48.6/30 = 1.62

48 divided by x = 48.6/x

Step-by-step explanation:

645/100

Factor the number:

Answers

Answer:

Hello some parts of your question is missing below is the missing part

c. If you randomly select a navel orange, what is the probability that it weighs between6.2 and 7 ounces

Answer: A) 0.0099

B) 0.6796

C) 0.13956

Step-by-step explanation:

weight of Navel oranges evenly distributed

mean ( u ) = 8 ounces

std ( б )= 1.5

navel oranges = X

A ) percentage of oranges weighing more than 11.5 ounces

P( x > 11.5 ) = [tex]P ( \frac{x - u}{ std} > \frac{11.5-8}{1.5} )[/tex]

= P ( Z > 2.33 ) = 0.0099

= 0.9%

B) percentage of oranges weighing less than 8.7 ounces

P( x < 8.7 ) = [tex]P ( \frac{x - u}{ std} > \frac{8.7-8}{1.5} )[/tex]

= P ( Z < 0.4667 ) = 0.6796

= 67.96%

C ) probability of orange selected weighing between 6.2 and 7 ounces?

P ( 6.2 < X < 7 ) = [tex]P (\frac{6.2-8}{1.5} < \frac{x - u}{ std} < \frac{7-8}{1.5} )[/tex]

= P ( -1.2 < Z < -0.66 )

= Ф ( -0.66 ) - Ф(-1.2) = 0.13956

In a group of 80 people, 50 can speak Nepali, 45 can speak English and 7 of them do not
speak both languages.
a) Find the number of people who speak both languages.
b) Also illustrate the above information in Venn diagram.

Answers

Answer:

Universal set is 80

Number of people that speak Nepali is 50

Number of people that speak English is 45

Number of people that do not speak both is 7

a. Number of people that speak both languages is 22

b. As above

Step-by-step explanation:

a. Let make number of people that speak both languages x

To get x

(50-x) + (45-x) + x + 7 = 80

(50-x) + (45-x) + x = 80 - 7

(50-x) + (45-x) + x = 73

Open bracket

50-x+45-x+x= 73

50+45-2x+x = 73

95 - x = 73

-x = 73 - 95

-x = -22

x = 22

Therefore, number of people that speak both languages is 22

b. To get venn diagram

Number of people that speak Nepali is 50 - 22 = 28

Number of people that speak English is 45 - 22 = 23

Therefore, total = 28+23+22+7 = 80

After 2 weeks of training Amanda learned a total of 5 appetizer recipes after 6 weeks of training how much appetizers will she learn

Answers

Answer:

Step-by-step explanation:

After 6 weeks of training, Amanda will learn 15 recipes.

What is ratio?

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Recipes learned by Amanda after 2 weeks of training = 5.

After 6 weeks of training, the number of recipes are required.

To find the number of recipes,

Use ratio property,

After 2 weeks of training = 5 recipes

After 1 week of training = 5/2 recipes.

Therefore, after 6 weeks of training = (5/2) x 6 = 15 recipes.

Amanda will learn 15 recipes after 6 weeks of training.

Answer: See explanation

Step-by-step explanation:

Your question isn't well written but let me help out. I saw a similar question.

Example 1: Aling Luz bought 3/8 yards of linen cloth which cost Php 72.00 per yard. She gave Php 1000.00 to the cashier.How much change will she get?

Since we are informed that Aling Luz bought 3/8 yards of linen cloth which cost Php 72.00 per yard, the amount she'll pay will be:

= 3/8 × 72

= Php 27

Since she gave the cashier Php 1000, her change will be:

= 1000 - 27

= Php 973
