What is the slope of the line through (-7, -8) and (0, 4)?

A. -12 over 7

B. -7 over 12

C. 7 over 12

D. 12 over 7

Generally speaking, arithmetic sequences have the form:

an=a1+(n-1)*d

Where:

an=the nth term in the sequence

a1=the 1st term in the sequence

n=the number of terms in the sequence

d=the difference between consecutive terms (i.e. d=an-an-1=a2-a1=a3-a2, etc.)

The SUM of the terms of an arithmetic sequence, notated Sn, is given by:

Sn=[n/2]*[2a1+(n-1)*d]

So if n=8 then:

a8=a1+7d=63

And if there are 94 terms in the sequence then:

S94=[94/2]*[2a1+93d]=47*(2a1+93d)=94a1+4371d=1000

So this is a system of equations where:

{ a1 + 7d = 63 (Multiply this first equation by -94 on both sides and add to second equation)

{ 94a1 + 4371d = 1000

-94a1 - 658d = -5922 (Add this new equation to second equation)

Therefore:

3713d = -4922

So:

d = -4922/3713

Answer: arithmetic / -30

Step-by-step explanation: This is an arithmetic sequence.

The reason I know that is because the same number is being

added each time to get the next term in the sequence.

In this case, we are adding -30 each time to reach the next term.

So the common difference is -30.

Answer:

lines a and b are parallel. The slopes are -1/3

None of the lines are perpendicular to each other.

Step-by-step explanation:

To figure out if any of the lines are parallel or perpendicular to each other, you have to find the slopes of each line. To find the slope look at the graph find the rise over run for all of the lines:

line a: This line goes down one every time it goes over 3, which can be represented by -1/3

line b: This lines goes down one every time it goes over 3, which can also be written as -1/3

line c: This line goes up 5 every time it goes over 2, which makes the slope 5/2

When two lines are parallel, they have the same slope. Line a and line b have the same slope, so they are parallel.

When two lines are perpendicular, their slopes are negative reciprocals of each other. Since none of the slopes are a negative reciprocal of another slope, we have no perpendicular lines.

Hope this helps :)

have watch a video yet if you have not it will help you on it

Step-by-step explanation:

Answer: (a) P(no A) = 0.935

              (b) P(A and B and C) = 0.0005

              (c) P(D or F) = 0.379

              (d) P(A or B) = 0.31

Step-by-step explanation: Pareto Chart demonstrates a relationship between two quantities, in a way that a relative change in one results in a change in the other.

The Pareto chart below shows the number of people and which category they qualified each public school.

(a) The probability of a person not giving an A is the difference between total probability (1) and probability of giving an A:

P(no A) = [tex]1-\frac{68}{1052}[/tex]

P(no A) = 1 - 0.065

P(no A) = 0.935

b) Probability of a grade better than D, is the product of the probabilities of an A, an B and an C:

P(A and B and C) = [tex](\frac{68}{1052})(\frac{258}{1052})(\frac{327}{1052})[/tex]

P(A and B and C) = [tex]\frac{5736888}{1164252608}[/tex]

P(A and B and C) = 0.0005

c) Probability of an D or an F is the sum of probabilities of an D and of an F:

P(D or F) = [tex]\frac{269}{1052} +\frac{130}{1052}[/tex]

P(D or F) = [tex]\frac{399}{1052}[/tex]

P(D or F) = 0.379

d) Probability of an A or B is also the sum of probabilities of an A and of an B:

P(A or B) = [tex]\frac{68}{1052} +\frac{258}{1052}[/tex]

P(A or B) = [tex]\frac{326}{1052}[/tex]

P(A or B) = 0.31

Answer:

When it yields a negative constant, the original function is everywhere concave down. In other words, when the second derivative of the equation of our parabola is positive, the parabola opens upward; when it is negative the parabola opens downward. Example 2: If y = -2(x-1)² + 3, determine the parabola's orientation.

Answer:

51 students will be accepted if 850 applicants apply for admission.

Step-by-step explanation:

With the information provided, you can use a rule of three to find the amount of students that will be accepted if 850 applicants apply for admission given that you know that Harvard University accepts 6 students for every 100 applicants:

100  →  6

850 →  x

x=(850*6)/100= 51

According to this, the answer is that 51 students will be accepted if 850 applicants apply for admission.

Answer:

About $804.70

Step-by-step explanation:

So, for this you will need the formula: "A = B(1 + r)^t" It is + 1 since it is an increase.

B = Initial Value

r = rate

t = time

A = B(1 + r)^t

A = 523(1 + 0.09)^5

A = 523(1.09)^5

A = 523(1.5386239549)

A = 804.700328413

A ≈ 804.70

You solve that by multiplying all the numbers and then you divide by 2.

Answer:

Step-by-step explanation:

Total sum of age of 12 students = 12*18 = 216;

Total sum of age of 8 students = 8*23 = 184;

Total sum of age of 20 students = 216+184 = 400;

Mean age of all the students = total age / number of students;

= 400/20 = 20 year

Answer: The answer would be 25

Step-by-step explanation: So the first thing you do, is multiply each number in parentheses first. So 2 mulitplied by 3 is 6. Then multiply 6 by 4 to get 25. Then add 1 to 24, to get 25. Hoped this helped
