What is the slope of line d and line c?
Answer:
Step-by-step explanation:
I understand why this was kind tough
the slope of line d is infinite and the slope of line c is zero
so line c 's equation looks like y = 3 ... it's kinda confusing but the line is always 3 so you could pick any x value and y = 3 still. the equation y=3 doesn't rely on x at all to answer it. But x is part of the "frame work" that is implied.
line d is x = 3 , again , y is part of the "frame work" and implied that y doesn't matter in this equations, you always have x = 3 .. or a vertical line , btw. line d does NOT pass the vertical line test , and therefore isn't a function, so the question is wrong, that d will have an equation, b/c there is an implication that d is a function when you say "what is the equation to line d" that is must be a function. But in this case it's not. hm :/ food for thought

15 is what percentage of 105
To do this, simply divide 15 by 105 multiplied by 100%.
So, we have:
[tex]\%Percent = \frac{15}{105} * 100\%[/tex]
[tex]\%Percent = \frac{15*100}{105}\%[/tex]
[tex]\%Percent = \frac{1500}{105}\%[/tex]

6. Missing data, nonrandom samples, and outlying observations True or False: If the data for an observation on either the dependent variable or one of the independent variables are missing at random, then the size of the random sample available from the population must be reduced, which reduces the estimator's precision and introduces a bias.
Answer:
False
Step-by-step explanation:
The answer to this question is false because the missing observation does not introduce bias to the estimator. But missing observations reduces the size of the sample that is available from the given population. Therefore reducing the precision of the estimators.
In conclusion, no bias is introduced because of missing observations so the answer is false.

Answer:
A, B, D
1/2, 4/2, 8/2
Step-by-step explanation:
Since all of the answer choices have common denominators, we can add the numerators to get 13.
Let's try out the different combinations.
1/2 + 4/2 + 2/2 = 7/2This fraction is not equivalent to 13/2.
4/2 + 2/2 + 8/2 = 14/2This fraction is not equivalent to 13/2.
1/2 + 2/2 + 8/2 = 11/2This fraction is not equivalent to 13/2.
1/2 + 4/2 + 8/2 = 13/2This fraction IS equivalent to 13/2, so the correct answer choices are A) 1/2, B) 4/2, and D) 8/2.
Write a function called Radians_To_Degrees which will convert an angle from Radians to Degrees. In your Lesson 06 script: a. convert 1.62 radians to degrees b. Convert pi/9 radians to degrees
Answer:
a) 92.9 degrees
b) 20 degrees
Step-by-step explanation:
Using the conversion factor;
180 degrees = pi radians
For 1.62 radians;
1.62 radians = x
pi radians = 180 degrees
Divide both expressions;
1.62/pi = x/180
pi * x = 1.62 * 180
pi * x = 291.6
x = 291.6/pi
x = 291.6/3.14
x = 92.9 degrees
Hence 1.62 radians is equivalent to 92.9 degrees
b) Recall that
pi radians = 180 degrees
pi/9 rad = y
Cross multiply
y * pi = 180pi/9
y = 180/9
y = 20 degrees
Hence pi/9 radians is equivalent to 20 degrees

In 2012 the average cost for a new midsized car was about
$31,000. New car prices tend to go up about 2% every year.
a. What is the multiplier for this situation?
b. If this trend continues, what will the cost be in 4 years?
c. Write an equation to calculate the cost in n years. What does
each of the factors in your equation represent?
Answer:
A) The multiplier for this situation is 0.02.
B) The cost in 4 years will be $ 33,555.39.
C) 31,000 x 1.02 ^ N = X
Step-by-step explanation:
Since in 2012 the average cost for a new midsized car was about $ 31,000, and new car prices tend to go up about 2% every year, to determine what is the multiplier for this situation, what will the cost be in 4 years if this trend continues and to write an equation to calculate the cost in n years the following calculations must be performed:
A)
31,000 x 2/100 = X
31,000 x 0.02 = X
Thus, the multiplier for this situation is 0.02.
B)
31,000 x 1.02 ^ 4 = X
33,555.39 = X
Thus, the cost in 4 years will be $ 33,555.39.
C)
31,000 x 1.02 ^ N = X
Here, N represents the number of years over which the price increase will be calculated, and X represents the price after that number of years.

A newspaper hires a polling company to determine the level of support in the county for raising property taxes in order to increase funding for local schools. The polling company calls phone numbers chosen at random from a phone number registry between the hours of 5 p.m. and 7 p.m. What are some potential sources of bias in this sampling method?
Some sources of bias may be:
The fact the company is calling in such a narrow time window. They need to expand their hours of operation. Not everyone has a listed phone number, and many cell phones are unlisted, so that leaves many people out of the picture. The sample is likely not representative of the population. The company may be better off doing email or social media surveying methods. Many people often get annoyed at unsolicited phone calls, so they may not be willing to do a survey. Those that do answer the survey may show off volunteer response bias which is often present in political surveys.Answer:
There are three correct answers:
Step-by-step explanation:
The method excludes people who have unregistered numbers.
The method excludes people who work between 5:00 P.M. and 7:00 P.M.
The method excludes people who do not have phones.

d. you just have to multiply everything
You are traveling down a country road at a rate of 95 feet/sec when you see a large cow 300 feet in front of you and directly in your lane. The cow is fearless, and staring you down. (Or perhaps she does not understand the gravity of the situation.) Regardless, if you simply hit your brakes, after t seconds, the car will be j(t) = 95t - 9t^2 feet from the point where the brakes were first applied.
1) Must you steer to avoid the cow, or can you rely solely on your brakes? Explain.
2) Graph J(t), j'(t), and j"(t) and Interpret their meanings in context.
3) Is there a time t after which the graphs in part (ii) probably do not accurately model the path of the car?
4) Write a piece-wise function using j(t) that would more accurately model the path of the car on the interval [0, 10], assuming the car did not move after it stopped. Sketch this graph and its derivative.
Answer:
1) You can rely solely on your brakes because when doing so the car will just travel 250ft from the point you hit your brakes till the point the car stopped completely, leaving you 50ft away from the cow.
2) See attached picture.
j(t) represents the distance from the point you hit the brake t seconds after you hit it in feet
j'(t) represents the velocity of the car t seconds after the brakes have been hit in ft/s.
j"(t) represents the acceleration of the car t seconds after the brakes have been hit in [tex]ft/s^{2}[/tex]
3) yes, any time after t=5.28 will not accurately model the path of the car since at that exact time the car will reach a velocity of 0ft/s and unless another force is applied to the car, then the car will not move after that time.
4) [tex]j(t)=\left \{ {{95t-9t^{2}; 0\le t<5.28s} \atop {250.69; 5.28s\leq t \leq 10s}} \right.[/tex]
[tex]j'(t)=\left \{ {{95-18t; 0\leq t<5.28s} \atop {0 ; 5.28s\leq t \leq 10s}} \right.[/tex]
(see attached picture for graph)
Step-by-step explanation:
1) In this part of the problem we need to find the time when the speed of the car is 0. Gets to a complete stop. For this we will need to take the derivative of the position function so we get:
[tex]j(t)=95t-9t^2[/tex]
[tex]j'(t)=95-18t[/tex]
and we set the first derivative equal to zero so we get:
95-18t=0
and solve for t
-18t=-95
[tex]t=\frac{95}{18}[/tex]
t=5.28s
so now we calculate the position of the car after 5.28 seconds, so we get:
[tex]j(5.28)=95(5.28)-9(5.28)^{2}[/tex]
[tex]j(5.28)=250.69ft[/tex]
so we have that the car will stop 250.69ft after he hit the brakes, so there will be about 50ft between the car and the cow when the car stops completely, so he can rely just on the breaks.
2) For answer 2 I take the second derivative of the function so I get:
[tex]j(t)=95t-9t^{2}[/tex]
[tex]j'(t)=95-18t[/tex]
j"(t)=-18
and then we graph them. (See attached picture)
j(t) represents the distance from the point you hit the brake t seconds after you hit it in feet
j'(t) represents the velocity of the car t seconds after the brakes have been hit in ft/s.
j"(t) represents the acceleration of the car t seconds after the brakes have been hit in [tex]ft/s^{2}[/tex]
3) yes, any time after t=5.28 will not accurately model the path of the car since at that exact time the car will reach a velocity of 0ft/s and unless another force is applied to the car, then the car will not move after that time.
4) [tex]j(t)=\left \{ {{95t-9t^{2}; 0\le t<5.28s} \atop {250.69; 5.28s\leq t \leq 10s}} \right.[/tex]
[tex]j'(t)=\left \{ {{95-18t; 0\leq t<5.28s} \atop {0 ; 5.28s\leq t \leq 10s}} \right.[/tex]

Answer:
31
Step-by-step explanation:
The linear equaiton is 3p + 2 = 11.Then the number of plants that fit on each shelf will be 3.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Ana wants to place 11 plants on 3 shelves each shelf holds the same number of plants there are two plants that do not fit.
Let 'p' be the number of plants in a row. Then the equation is given as,
3p + 2 = 11
Simplify the equation, then we have
3p + 2 = 11
3p = 11 - 2
3p = 9
p = 9 / 3
p = 3
The linear equaiton is 3p + 2 = 11.Then the number of plants that fit on each shelf will be 3.
More about the solution of the equation link is given below.
