Answer:
[tex](x,f(x)) = (-1,8)[/tex] -- Another point
[tex]a = 8[/tex]
Step-by-step explanation:
Given
[tex]f(x) = a|x|[/tex]
[tex](x,f(x)) = (1,8)[/tex]
Solving (a): Another point
Substitute 1 for x and 8 for f(x) in [tex]f(x) = a|x|[/tex]
[tex]8 = a|1|[/tex]
Remove absolute bracket
[tex]8 = a*1[/tex]
[tex]8 = a[/tex]
[tex]a = 8[/tex]
Substitute 8 for a in [tex]f(x) = a|x|[/tex]
[tex]f(x) = 8|x|[/tex]
Let x = -1
[tex]f(x) = 8|-1|[/tex]
Remove absolute bracket
[tex]f(x) = 8*1[/tex]
[tex]f(x) = 8[/tex]
So, another point is:
[tex](x,f(x)) = (-1,8)[/tex]
Solving (b): The value of a
This has been solved in (a) above
[tex]a = 8[/tex]

which one is supposed to be correct?
The solution of 25x = 300 is 12. The solution of 25x>300 is all values
Answer: x>12 so anything greater than 12 is correct
Step-by-step explanation:
The solution to the given inequality is all values that are greater than 12.
Inequality:Important information:
The solution of [tex]25x = 300[/tex] is 12.The given inequality is [tex]25x>300[/tex].We have,
[tex]25x>300[/tex]
Divide both sides by 25.
[tex]\dfrac{25x}{25}>\dfrac{300}{25}[/tex]
[tex]x>12[/tex]
Therefore, the solution to the given inequality is all values that are greater than 12.

For each of the questions below, a histogram is described. Indicate in each case whether, in view of the Central Limit Theorem, you can be confident that the histogram would look like approximately a bell-shaped (normal) curve, and give a brief explanation why (one sentence is probably sufficient). There are no data for these questions, so you will not need to use the computer to answer these questions.
a. A police department records the number of 911 calls made each day of the year, and the 365 values are plotted in a histogram.
b. The day before an election, fifty different polling organizations each sample 500 people and record the percentage who say they will vote for the Democratic candidate. The 50 values are plotted in a histogram. The fifty polling organizations also record the average age of the 500 people in their sample, and the 50 averages are plotted in a histogram.
c. One hundred batteries are tested, and the lifetimes of the batteries are plotted in a histogram.
d. Two hundred students in a statistics class each flip a coin 50 times and record the number of heads. The numbers of heads are plotted in a histogram. Two hundred students in a statistics each roll a die 40 times and record the sum of the numbers they got on the 40 rolls. They make a histogram of the 200 sums.
e. One thousand randomly chosen people report their annual salaries, and these salaries are plotted in a histogram.
Solution :
a). This histogram is not a bell shaped.
Here we cannot use the theorem of the central limit as the histogram is being plotted by using 365 samples data values of the one sample.
b). This histogram may be bell shaped approximately since the sample size is large.
Here there are 50 sample each having a size of 500 and there is 50 sample proportions. The histogram shows sampling distribution of the sample proportion. Thus the central limit theorem can be used.
The histogram is approximately bell shaped as there is 50 samples of each having 500 size and an average of 50. Thus the central limit theorem can be used.
c). The histogram is not a bell shaped.
In this case central limit theorem cannot be used as the histogram is plotted by using 100 sample data values of one sample.
d). The histogram is a bell shaped since the sample size is large.
In this case 200 samples of each having a size of 50 and a data values of 50. The histogram here shows a sampling distribution of the sample proportion. Thus the central limit theorem can be used.
In the second also the histogram is of bell shaped as the sample size is large.
There are 200 samples of each sample having a size of 40 and they have 40 data values , i.e. sum of rolls.
e). It is not a bell shaped.
The histogram here is plotted using 100 sample data values having one sample. Therefore we cannot use the central limit theorem.

What is the probability of rolling a six on a fair die?
Answer: 1/6
Step-by-step explanation: To find the probability of rolling a six,
let's use our ratio for the probability of an event.
number of favorable outcomes / total number of outcomes
Since only one side of a die has a six on on it, the number of favorable
outcomes for rolling a six is 1 and since there are six sides to a die and it's
equally likely that the die will landy on any of these sides, the total number
of outcomes is 6.
So the probability of rolling a six is 1/6.

Consider the angle shown below with an initial ray pointing in the 3-o'clock direction that measures θ radians (where 0≤θ<2π). The terminal point is (1.33,−2).
What is the angle's measure (in radians)?
θ=
Answer:
5.3 or (4217pi/2500)
Step-by-step explanation:
Create a right triangle with the coordinates provided.
We can ignore the negative sign and create the equation
[tex]tan(x) = \frac{1.33}{2} [/tex]
x = 33.624
We then add 270 and x together because the coordinates are in the 4th quadrant.
angle = 303.624
To convert to radians, we multiply this number by pi/180
5.3 radians
The measure of the angle is approximately [tex]1.687\pi[/tex] radians.
By trigonometry we can determine the direction of the terminal ray ([tex]\theta[/tex]), in radians, by the following inverse trigonometric function:
[tex]\theta = \tan^{-1}\frac{y}{x}[/tex] (1)
Since [tex]x > 0[/tex], [tex]y <0[/tex] and angle is in standard position, the angle must have a direction greater than [tex]\frac{3\pi}{2}[/tex] radians and less than [tex]2\pi[/tex] radians. Hence, we conclude that direction of the angle is:
[tex]\theta = \tan^{-1} \left(\frac{-2}{1.33} \right)[/tex]
[tex]\theta \approx 1.687\pi\, rad[/tex]
The measure of the angle is approximately [tex]1.687\pi[/tex] radians.

1) A brick wall has 60 bricks in the bottom row but each row has 3 fewer bricks than the previous one. How
many bricks are in the 12th row?
There are 27 bricks in the 12th row. Hope this helps ! :)
Answer:
24 bricks
Step-by-step explanation:
The equation of the bricks per row can be:
b = 60 - 3r
where r = row and b = bricks.
if r = 12:
[tex]b = 60 - 3 * 12\\b = 60 - 36\\b = 24[/tex]

Median - The middle number in a set a data
First, you need to list the numbers least, on the left, to greatest, on the right.
3, 3, 4, 5, 5, 5, 6, 8, 8
Once you have done this, you can follow these steps.
Cross off the lowest number. Cross off the highest number. Repeat until there is one or two numbers left.
3, 4, 5, 5, 5, 6, 8
4, 5, 5, 5, 6

We have to determine, find the pattern and what numbers come next
We have given that, 61, 54, 47, 40.
What is the series?
A series is, roughly speaking, a description of the operation of adding infinitely many quantities, one after the other.
61-54=7
54-47=7
47-40=7
So the next term is
40-7=33
Therefore the relation is the descending the series by 7 and the next term is 33.

Write a formula for rrr in terms of \thetaθtheta for the following figure.
Answer: r = 4cm/θ
Step-by-step explanation:
For a circle of radius R, the perimeter is:
P = 2*pi*R
Now, if we have an arc with an angle θ, the cord of this arc is:
C = (θ/2*pi)*2*pi*R
Where you can see that if θ = 2*pi (this is the full circle) we have the perimeter of the circle.
In this case, we can see that the cord for an angle θ is 4cm, then:
C = 4cm = (θ/2*pi)*2*pi*r = θ*r
Now we can solve this for r:
r = 4cm/θ
