Multiply 3 with 8 to turn the 3 whole points into parts.
3 x 8 = 24
Add the 7 pieces you already have,
24 + 7 = 31
Put it over 8 then you have your answer.

f(x) is concave upwards for all x.

Answers

Answer:
a. f(x) has a relative maximum at x = 0.
Step-by-step explanation:
Since f' is decreasing, the second derivative is negative. That means the graph is concave downward, so any critical point is a relative maximum.
f(x) has a relative maximum at x=0 (where f'(0) = 0)
__
There is no indication that the second derivative is ever zero, so there is no point of inflection.
No values of f(x) are given, so we cannot say whether the function passes through the origin.

Answers
Answer:
Solution given:Barbara reads

1 day=100/4=25pages
judy reads
54pages =3days
1 day=54/3=18 pages
nancy reads

average page=[25+18+32]/3=25 pages per day is a required rate.
A polling agency reported that the proportion of 12th grade students who are engaged is 0.34. Engagement is defined as students' involvement and enthusiasm with school. The superintendent of one high school district believes the engagement of her students is higher than the proportion reported. She randomly surveys 90 of the 3600 students in the district and finds that 38 reported being engaged in school.
Required:
a. What type of variable is "engaged"?
b. What is the sample proportion of students in this high school district who are engaged?
Answers
Answer:
a) "engaged" is a quantitative and continuous variable.
b) The sample proportion of students in this high school district who are engaged is 0.4222
Step-by-step explanation:
Given the data in the question;
Polling reports shows that 0.34 12th grade students are engaged
the principal surveyed 90 of the 3600 students,
number of students reported to be engaged is 38
a)
"engaged" is a quantitative and continuous variable.
b) the sample proportion of students in this high school district who are engaged.
Sample proportion of engaged = number of students reported to be engaged / total number of students surveyed
so
Sample proportion of engaged = 38 / 90
Sample proportion of engaged = 0.4222
Therefore, the sample proportion of students in this high school district who are engaged is 0.4222

O (-14, -54)
Answers
Answer:
(-14, -54)
Step-by-step explanation:
Let's call the functions f and g
f(x) = ax + b
f(0) = a*0+b = 2
f(3) = a*3 + b = 14
From f(0) = 2 we know that b = 2
f(3) - f(0) = a*3 = 14 - 2
a = 4
We know that f(x) = 4x + 2
g(x) = cx + d
g(0) = -12
g(3) = -3
From g(0) = -12 we know that d = -12
g(3) - g(0) = c*3 = -3 - (-12) = 9
c = 3
We know that g(x) = 3x - 12
Now we need to solve
4x + 2 = 3x - 12
x + 2 = -12
x = -14
y = 4*(-14) + 2 = -56 + 2 = -54
y = 3*(-14) - 12 = -42 - 12 = -54
Checks out.
The solution to the system of linear functions that is represented by both tables is: (-14, -54).
What is the Solution of a System of Linear Functions?The solution of a system of two linear function is the point where the the x-coordinate and the y-coordinate of both linear functions are the same.
To find the solution, state the equation that represents each of the functions in the given tables:
y = 4x + 2 represents table 1
y = 3x - 12 represents table 2.
Thus, set both equations equal to each other.
4x + 2 = 3x - 12
Combine like terms
4x - 3x = -2 - 12
x = -14
Find the value of y by substituting x = -14 into y = 3x - 12:
y = 3(-14) - 12
y = -54.
Therefore, the solution to the system of linear functions that is represented by both tables is: (-14, -54).

If a certain number x is multiplied by 6

Answers
Answer: x= -1
Step-by-step explanation: 6x = 2x-4 4x= -4 and x=-1
From the given statement the unknown number is found to be - 1
The given statements can written in algebraic form as follows;
the unknown number = x
the number is multiplied by 6 = 6x
four less than twice the same number = 2x - 4
then, from the given statement the final equation equation becomes;
6x = 2x - 4
This unknown number can be solved by collecting similar terms together;
6x - 2x = -4
4x = -4
divide through by 4
[tex]\frac{4x}{4} = \frac{-4}{4} \\\\x = -1[/tex]

Step-by-step explanation:
Consider the functions k(x) = x + 1, m(x) = x - 4, n(x) = x + 5, and f(x) = k(x) • m(x) · n(x). a. Determine the degree of the function f(x).
Answers
Answer:
[tex]Degree = 3[/tex]
Step-by-step explanation:
Given
[tex]k(x) = x + 1[/tex]
[tex]m(x) = x - 4[/tex]
[tex]n(x) = x + 5[/tex]
[tex]f(x) = k(x) * m(x) * n(x)[/tex]
Required
The degree of f(x)
First, calculate f(x)
[tex]f(x) = k(x) * m(x) * n(x)[/tex]
[tex]f(x) = (x +1) * (x - 4) * (x + 5)[/tex]
Expand
[tex]f(x) = (x +1) * (x^2 - 4x + 5x - 20)[/tex]
[tex]f(x) = (x +1) * (x^2 + x - 20)[/tex]
Further Expand
[tex]f(x) = x^3 + x^2 - 20x +x^2 + x - 20[/tex]
Collect like terms
[tex]f(x) = x^3 + x^2 +x^2 - 20x + x - 20[/tex]
[tex]f(x) = x^3 + 2x^2 - 19x- 20[/tex]
The degree of f(x) is the highest power of x.
Hence:
[tex]Degree = 3[/tex]
A particular brand of tires claims that its deluxe tire averages at least 50,000 miles before it needs to be replaced. From past studies of this tire, the standard deviation is known to be 8,000. A survey of owners of that tire design is conducted. From the 28 tires surveyed, the mean lifespan was 46,500 miles with a standard deviation of 9,800 miles. Using alpha 0.05, is the data highly inconsistent with the claim?
Answers
Answer:
p-value = 0.01044
Hence, P-value ( 0.01044 ) is less than level of significance ( 0.05 )
We reject H₀
Reject the claim that deluxe tires averages at least 50000 miles before it needs to be replaced.
∴ the data is highly inconsistent with the claim
Step-by-step explanation:
Given the data in the question;
x' = 46500
σ = 8000
sample size n = 28
Null hypothesis H₀ : μ ≥ 50000
Alternative hypothesis H₁ : μ < 50000
level of significance ∝ = 0.05
Using Test statistics;
Z = [(x' - μ ) / (σ√n)] ~ (0,1)
we substitute
Z = [(46500 - 50000 ) / (8000√28)]
= -3500 / 1511.85789
= - 2.31
{ since alternative hypothesis is left tailed } from z-table;
p-value = P( z ≤ -2.32 )
p-value = 0.01044
Hence, P-value ( 0.01044 ) is less than level of significance ( 0.05 )
We reject H₀
Reject the claim that deluxe tires averages at least 50000 miles before it needs to be replaced.
∴ the data is highly inconsistent with the claim
