Answer:

[tex] f(-8) = -25 [/tex]

Step-by-step explanation:

[tex] f(x) = -x^2 - 3x + 15 [/tex]

[tex] f(-8) = -[(-8)^2] - 3(-8) + 15 [/tex]

[tex] f(-8) = -(64) + 24 + 15 [/tex]

[tex] f(-8) = -25 [/tex]

Answer:

put in the y int- which is 5 and then the slope which is 1/1

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:

6

Step-by-step explanation:

Coefficient term are the numbers that multiply the variables or letters.

In the given expression:

13a means 13 times a , and a is the variable,

so 13 is the coefficient .

6b means 6 times b , and b is the variable ,

so 6 is the coeffi.

Answer:

13

Step-by-step explanation:

Answer:

the number in front of a term is called a convention examples of single terms three times is a single term the three contents so then it would probably be 24 because 7284 time be planted in their preferred method to show multiplication example 3 evaluate the expression and then you go wide equals 6 and 24 hope this helps it's an example not the real answer though LOL

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 :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

A living room wall is 13 feet long. If the perimeter of the rectangular living room is 56 feet long.

The formula for the perimeter of the rectangular living room =

P = 2(L + W)

P = 2L + 2W

L = Length = 13 feet

W = Width

P = 56 feet

56 = 2 × 13 + 2 W

56 = 42 + 2W

56 - 42 = 2W

14 = 2W

W = 14/2

W = 7

The width of the rectangular room is 7 feet long

A rectangular room would have 4 walls

Answer:

$239.02 and $10177

Step-by-step explanation:

Ann:

2868.32/6= 478.05

478.05/2= 239.02

Ann's sister:

3562.28/7= 508.89

508.89/5= 101.77

dont know if i did this right to be completely honest. but i feel like it's right. sorry if it's not.

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:

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:

25

Step-by-step explanation:

1+(2)(3)(4)

=1+(6)(4)

=1+24

=25

Hope this helps!

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

Answer:

Step-by-step explanation:

Given function:

Finding h(-67)

Correct option is B.

Concepts:

Answer: B. 3158

We know:

h(x) = -49x − 125

Finding h(-67)

h(-67) = -49(-67) - 125 = 3283 - 125 = 3158

ANSWER = 3158/B

Answer:yes they are

Step-by-step explanation:

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.
