Answer: [tex]37000+2500n[/tex]
Step-by-step explanation:
Given
John makes $82,000 per year after 18 years
If he would have to get a raise of $2500 per year
Suppose he starts with a salary of [tex]x[/tex]
after the first year, his salary would be
[tex]\Rightarrow x+2500[/tex]
After 2 years, the salary would be
[tex]\Rightarrow x+2500+2500=x+2\times 2500[/tex]
Similarly, after n years salary is
[tex]\Rightarrow x+2500n[/tex]
For 18 years, it is
[tex]\Rightarrow x+2500\times 18=82,000\\\Rightarrow c=82,000-45,000=\$\ 37,000[/tex]
So, after n years of working salary is [tex]37,000+2500n[/tex]

Recently many companies have been experimenting with telecommuting, allowing employees to work at home on their computers. Among other things, telecommuting is supposed to reduce the number of sick days taken. Suppose that at one firm, it is known that over the past few years employees have taken a mean of 5.4 sick days. This year, the firm introduces telecommuting. Management chooses a simple random sample of 80 employees to follow in detail, and at the end of the year, these employees average 4.5 sick days with a standard deviation of 2.7 days.
a) Describe the population in the context of this problem
b) Describe the parameter u in the context of this problem.
c) Describe the sample in the context of this problem.
d) Describe the statistic in the context of this problem
e) The firm would like to know if there is evidence that the true mean number of sick days for all employees of the firm has decreased after telecommuting was introduced. State the hypotheses. Use ?-0.10.
f) Check the assumptions. If you don't know if an assumption is satisfied based on the information provided, then state "We must assume
g) Calculate the test statistic
h) Find the p-value.
i) Make a decision.
j) State the conclusion in terms of the problem.
Answer:
A.) Population : All employees at a firm
B.) μ = 5.4
C.) Sample : 80 employees at a firm
D.) Sample mean, x bar = 4.5
Step-by-step explanation:
From the question :
E.)
H0: μ ≥ 5.4
H1 : μ < 5.4
F.)
If Pvalue < α ; Reject H0
G.)
Test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(4.5 - 5.4) ÷ (2.7/sqrt(80))
-0.9 ÷ 0.3018691
= - 2.98
H.)
Pvalue fro Zscore calculator, α = 0.10 = 0.002882
I.)
Decision :
0.002882 < 0.10
Since, Pvalue < α ; We reject the Null
J.)
We Can conclude that the true mean number of sick days for all employees of the firm has decreased after telecommuting was introduced
if 25,m+1,35 are arithmetic sequence then find the value of m
Answer:
m = 29
Step-by-step explanation:
You are counting by fives.
25, 30, 35
m + 1 = 30
m + 1 - 1 = 30 - 1
m = 29
25, (29 + 1), 35
25, 30, 35
The value of m is equal to 29
What is arithmetic sequence?An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.
An arithmetic sequence, therefore, is defined by two parameters, viz. the starting term and the common difference.
We are counting by fives.
m + 1 = 30
Now subtract 1 on both sides;
m + 1 - 1 = 30 - 1
m = 29
Thus substituting the value to find other terms;
25, (29 + 1), 35
The sequence is

having trouble with this problem, pls help :/ I know the answer, just not how to get there. (ap calc ab, integrals)
Answer: D) 101
Step-by-step explanation:
By linearity, we can break it up into 2 integrals. The integral and derivative of f easily cancel out
[tex]\int\limits^{10}_{-1} {(2x+0.5f'(x))} \, dx =\int\limits^{10}_{-1} {2x} \, dx +0.5\int\limits^{10}_{-1} {f'(x)} \, dx =x^2|^{^{10}}_{_{-1}}+0.5f(x)|^{^{10}}_{_{-1}}\\=(100-1)+0.5(f(10)-f(-1))=99+0.5(8-4))=101[/tex]
I used the table for values of f(x) at 10 and -1. Wouldn't be surprised if this was part of a series of questions about f because I really can't see how you could use the hypothesis that f is twice differentiable on R. Same for the other table values. I'm curious about how you found the answer. Was it a different way?

From the attached: Angles ACD, DCE and ECB lie on a straight line.
Where
[tex]ACD = 90[/tex] [tex]DCE = 53[/tex] [tex]ECB = g[/tex]
This means that:
[tex]ACD + DCE + ECB = 180[/tex]
[tex]90 + 53 + g = 180[/tex]
[tex]143 + g = 180[/tex]
Subtract 143 from both sides

Lauren brings brownies to class and gives 3/5 of them to Peter, Wendy, and Michael. If she gave them 21 brownies, how many did she bring to class?
Answer:
If 3/5 of all the brownies is 21, then 5/3 of 21 is the number of the brownies that Lauren brought in.
That probably sounded super confusing. When multiplying a number by a reciprocal of a fraction (a fraction where the numerator and denominator is reversed), the previous fraction multiplication is reversed.
Multiplying 21 with 5/3 will give us the original number of brownies.
Lauren originally brought 35 brownies.

type an (x,y) ordered pair to put a point on this line.
Answer:
(-2, 5)
Step-by-step explanation:
The ordered pair (x, y) for the given line can be obtained from the graph as (-4, 1).
What is the equation for a straight line?A straight line can be written in the form of equation as, y = mx + c.
Two straight lines intersect each other only at one point.
When two straight lines are parallel to each other the angle between them is zero.
The graph of the line is given.
In order to find the coordinate of a point do as follows,
Draw a perpendicular line from any point on the line to x-axis.
The intersection of this line with x-axis will give the x-cordinate.
Similarly, find y-coordinate by drawing a perpendicular line to y-axis.
Applying the above procedure, a point is obtained as (-4, 1).
Hence, the ordered pair for the line shown in the graph is (-4, 1).

A population of bacteria is initially 500. After two hours the population is 250. If this rate of decay continues, find the exponential function that represents the size of the bacteria population after t hours. Write your answer in the form f(t)=a(b)t. If you need to round any decimals, round to four decimal places.
Answer:
500(1/2)^t/2
Step-by-step explanation:
Use the exponential function f(x)=a(b)ct. The initial population, 500, gives the the point (0,500) and leads to coefficient of the exponential function, a=500.
f(t)=2000(b)ct
After 2 hours, the population has decreased by half. This means the common ratio is one-half, b=12. Because it takes 2 hours for the population to be cut in half, we know ct=1 when t=2, therefore c=1t and c=12. This gives the equation:
f(t)f(t)=500(12)12(t)=500(12)t2
Alternate Solution
The situation shows there are two points (0,500) and (2,250). Plugging the first point in, you solve for a=500 as follows:
500a=a(b)0=500
The decay coefficient, b, can be determined by substituting in the value for a and the point (2,250) and the solving as follows:
25025050012(12)12b=500(b)2=b2=b2=b≈0.7071
This gives the final exponential equation:
f(t)=500(0.7071)t
When the exponential function that represents the size of the bacteria population after t hours is = [tex]500(1/2)\wedge t/2[/tex]
Calculation of Exponential functionWhen we Use the exponential function f(x)=a(b)ct. Then, The initial population, 500, Also, gives the point (0,500) and then leads to the coefficient of the exponential function, a is =500.
Then, f(t)=2000(b)ct
After that, for 2 hours, the population decreased by half. Then, This means the common ratio is one-half, b=12. Because it takes 2 hours for the population to be cut in half, Now, we know ct=1 when t=2, therefore c=1t, and c=12. This gives the equation:
Then, f(t)f(t)=500(12)12(t)=500(12)t2
Now, an Alternate Resolution
When The situation shows there are two points (0,500) and (2,250). Plugging the first point in, you solve for a is =500 as follows:
After that, 500a=a(b)0=500
Then, The decay coefficient, b, can be determined by substituting the value for a and the point (2,250) and also the solving as follows:
Now, 25025050012(12)12b =500(b)2=b2=b2=b≈0.7071
So, This gives the final exponential equation:
Therefore, f(t) is =500(0.7071)t

Step-by-step explanation:
The capital letter 'F' can be described as letter can be presented as follows;
Two horizontal parallel lines touching and perpendicular to a common transversal
Therefore, the parallel lines in the letter 'F' and their common transversal form corresponding angles below each parallel line and the common transversal
The two horizontal lines in the capital letter Z and the inclined transversal form alternate angles between the transversal and the parallel lines, in the region between the parallel lines and on opposite sides of the transversal
