Give the slope of the line which is parallel to y=−3x+7 (can you give me the equation?)

Answers

Answer:

Slope is -3, equation is y=-3x+b, where b can be any number but not 7.

Step-by-step explanation:

Parallel lines have the same slope, so the slope of a line parallel to this is also -3.

An example of a parallel line to this is y=-3x+2, or y=-3x-4.

Answer:

Step-by-step explanation:

Usually in a problem of this sort you must supply one point through which the new line passes; here you have not yet done that.    

Let's suppose that the new line, which is parallel to y=−3x+7, passes through the point (0, 2).  Remembering that parallel lines have the same slope, we

write the new line as y = mx + b and replace m with -3; we also replace x with 0 and y with 2:

2 = -3(0) + b.  Solving for b, we get b = 2.  Thus, the desired equation of the line parallel to y=−3x+7 and passing through (0, 2) is

y = -3x + 2

Your answer is that all angles are equal to 66.

Angle 3 and angle 7 are equal, which we know because corresponding angles are equal (angles that make an ‘F’ shape).

This means we can form an equation because we know what angle 3 and angle 7 are:

2x + 40 = 3x + 27

- 2x

40 = x + 27

- 27

13 = x

Therefore angle 7 is 3(13) + 27 = 66, and so is angle 3.

We also know that angle 5 is equal to 66, because it is vertically opposite to angle 7 and vertically opposite angles are equal.

Answer:

why does it say college even tho this is a question on my homework

Step-by-step explanation:

and i'm in 7th grade.

Three methods, A, B and C, are available for teaching a certain industrial skill. The failure rate is 15% for A, 5% for B and 10% for C. The method A is used 30%, B is used 40% and C is used 30% of the time. A worker is taught the skill by one of the methods but fails to learn it correctly. a. (10 points) What is the probability that he was taught by method A? b. (5 points) What is the probability of B given A?

Answers

Answer:

a) so the correct answer is that the probability that method A has been taught is 0.4737

b) the probability that B receives A is 0.5

Step-by-step explanation:

With the previous data we know that 3 methods teach an industrial skill and when putting into practice a worker does not learn, we have the failure rates like this:

method A fails 15%

method B fails: 5%

method C fails: 10%

usage percentages:

A: 30%

B: 40%

C: 30%

a) the probability that method A has been taught is as follows:

P (failure rate) = P (A) * P (failure rate A) + P (B) * P (failure rate B) + P (C) * P (failure rate C)

we replace the data obtaining:

P = 0.3 * 0.15 + 0.4 * 0.05 + 0.3 * 0.1 = 0.095

P ( failure rate A) = P (A) * P (failure rate A) / P (failure rate)

we replace the data obtaining:

 0.3 * 0.15 / 0.095 = 0.4737

so the correct answer is that the probability that method A has been taught is 0.4737

b) the probability that B receives A is as follows:

P (B | A) = P (B) = 0.50

Josh types the 5 entries in the works cited page of his term paper in random order, forgetting that they should be in alphabetical order by author. What is the probability that he actually typed them in alphabetical order?

Answers

Answer:

0.83% probability that he actually typed them in alphabetical order.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The number of ways in which n terms can be arranged is given by:

[tex]A_{n} = n![/tex]

Desired outcomes:

Only one outcome in which the five entries are in alphabetical order, so [tex]D = 1[/tex].

Total outcomes:

We want to arrange 5 entries. So

[tex]T = A_{5} = 5! = 120[/tex]

Probability:

[tex]p = \frac{D}{T} = 0.0083[/tex]

0.83% probability that he actually typed them in alphabetical order.

A small company manufactures both large and small grandfather clocks. The company can make no more than 8 clocks a day. They want to build no more than 5 large clocks and no more than 6 small clocks per day. The company makes a profit of $100 on each large clock and $75 on each small clock. The company wishes to maximize its profit.

What is the objective function for this situation?


8 ≥ x + y


8 ≥ 100x + 75y


P ≥ 100x + 75y


P = 100x + 75y

Answers

Answer:

  P = 100x + 75y

Step-by-step explanation:

The objective is profit, so the objective function is the function that defines profit:

 P = 100x + 75y

where x is the number of large clocks made and y is the number of small clocks made per day.

__

Comment on other choices

Inequalities are generally associated with constraints on the manufacturing. Here, those would be ...

0 ≤ x ≤ 5   no more than 5 large clocks0 ≤ y ≤ 6   no more than 6 small clocksx + y ≤ 8   no more than 8 clocks total

The variables are constrained to be non-negative, because we cannot build a negative number of clocks.

__

To maximize profit in this situation, the maximum possible number of large clocks should be produced, since they are the most profitable. Then the remaining capacity should be used to produce as many small clocks as possible: 5 large clocks and 3 small clocks for a profit of $725 per day.

Part B: What is the probability that a student who does not like watching television also does not like reading? Explain your answer. (5 points)​

~ 2 kilometers in length of the actual path ~

Step-by-step explanation:

Let us plan out our steps, and solve for each:

1. Given the information, let us create a proportionality as such:

        1       =           10,000      ⇒   x - centimeters in length of actual path

       20                    x

2. Now let us cross multiply, and solve through simple algebra for x:

10,000 * 20 = x,

x = 200,000 centimeters of the width of the item in reality

3. The answer demands in km, so let us convert 200,000 cm ⇒ km:

200,000/100,000 = 2 kilometers in length of the actual path

What are the x- and y-intercepts of the graph of this equation?

Answers

Answer:

Step-by-step explanation:

y intercept is -3

x intercept is 4

Answer: x intercept = 4 and y intercept = -3

Step-by-step explanation:

In order to find the x intercept, set y=0 and solve the equation.

3x-4y-12=0

3x-4(0)-12=0

3x-12=0

add 12 to both sides

3x=12

divide both sides by 3

x = 4

The x intercept is 4.

To find the y intercept, set x = 0.

3x-4y-12=0

3(0)-4y-12=0

-4y-12=0

add 12 to both sides

-4y=12

divide both sides by -4

y = -3

The y intercept is -3.

Vanessa about 5 feet of ribbon she cut off 36 inches to wrap a package and 18 inches to decorator's scrapbook how much ribbon does Vanessa have left

Answers

Answer:

12 × ? = 12?

36 = 12?

? = 36/12

? = 3 feet
