Answer: y = (16/3)*x - 13.33
Step-by-step explanation:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Then for our particular case, we know that the line passes through the points (4, 8) and (1, -8)
Then the slope for this line will be:
a = (8 - (-8))/(4 - 1) = 16/3
Then our line is something like:
y = (16/3)*x + b
We need to find the value of the y-intercept b.
We know that this line passes through the points (4, 8) and (1, -8)
Then we can just replace the values of one of these points in our linear equation, for example, if we se the first one we get:
x = 4 and y = 8
replacing that in our equation we get:
8 = (16/3)*4 + b
8 - (16/3)*4 = b
-13.33 = b
Then the equation for our line is:
y = (16/3)*x - 13.33

So you must do tan(27)=x/2000Then once you have x you do: x^2+y^2=c^2 solve for c then add up all the sides and then subtract your total by 2000 to get the differenceIn one house, a realtor decorates 4 twin beds and 1 queen bed with a total of 18 pillows.
In another house, she decorates 4 twin beds and 4 queen beds with a total of 36 pillows.
She puts the same number of pillows on each twin bed, and the same number of pillows on each queen bed.
How many pillows does she put on each twin bed?
How many pillows does she put on each queen bed?
Answer:
The answer would be 3 pillows on each twin bed and 6 pillows on each queen bed.
Step-by-step explanation:
first house:
3 pillows x 4 twin beds = 12 pillows
18 total pillows - 12 twin bed pillows = 6 queen bed pillows
Second house
6 queen bed pillows x 4 queen beds = 24 queen bed pillow
3 twin bed pillows x 4 twin beds = 12 twin bed pillows
24 queen bed pillow + 12 twin bed pillows = 36 total pillows
Answer:
3 pillows on each twin bed and 6 pillows on each queen bed.

Plastic Rods
A factory makes rods by cutting plastic pipes that are 5 feet long into 8 rods.
Part A
How long is each rod?
40
feet
You may use the scratchpad to show your work.
Enter your answer as a fraction or a mixed number.
Part B
What is the total length of 13 rods?
Answer
65 feet long
Step-by-step explanation:
15x5 is 65
Answer:
Step-by-step explanation:
5 feet ÷ 8 = 5/8 of a foot for each rod.
(In inches that would be 5/8 × 12 inches = (5 × 12)/8 inches = 60/8 inches = 15/2 inches = 7 1/2 inches.)
13 rods would be 13 × 5/8 feet = (13 × 5)/8 feet = 65/8 feet = 8 1/8 feet

This table models function m.
Answer:
A: The y-intercept of function m is less than that of function n.
Step-by-step explanation:
From the table, we see that when x = 0, m(x) = -6.
This means that the y-intercept of function m is -6.
For the function "n", we are told it passes through (-1, 0) and (0, 2)
We see that at the second coordinate, at x = 0, y = 2.
This means that the y-intercept of the n function is at 2.
Therefore,we conclude that the y-intercept of function m is less than that of function n.

A university class has 26 students: 12 are art majors, 9 are history majors, 5 and are nursing majors. The professor is planning to select two of the students for a demonstration. The first student will be selected at random, and then the second student will be selected at random from the remaining students. What is the probability that the first student selected is a history major and the second student is a nursing major?
Answer:
6.9%.
Step-by-step explanation:
Given that a university class has 26 students: 12 are art majors, 9 are history majors, 5 and are nursing majors, and the professor is planning to select two of the students for a demonstration, where the first student will be selected at random, and then the second student will be selected at random from the remaining students, to determine what is the probability that the first student selected is a history major and the second student is a nursing major the following calculations must be performed:
26 = 100
9 = X
9 x 100/26 = X
900/26 = X
34.61 = X
25 = 100
5 = X
500/25 = X
20 = X
0.2 x 0.3461 = X
0.069 = X
Thus, the probability that the first student selected is a history major and the second student is a nursing major is 6.9%.
Answer:
6.9%

m = 4
Step-by-step explanation:
[tex] \because ABCD\sim QRST[/tex]

Solve the differential equation [tex]\frac{1}{6x} * \frac{dy}{dx} = y\sqrt{3x^{2} - 1 }[/tex]
A. [tex]e^{2/3} \sqrt{(3x^{2} -1)^{3}}[/tex]
B. [tex]C*e^{2/3} \sqrt{(3x^{2} -1)^{3}}[/tex]
C. None of these
This ODE is separable as
1/(6x) dy/dx = y √(3x ² - 1)
→ dy / y = 6x √(3x ² - 1) dx
Integrate both sides:
∫ dy / y = ∫ 6x √(3x ² - 1) dx
The left side is trivial. For the right side, substitute u = 3x ² - 1 and du = 6x dx :
∫ dy / y = ∫ √u du
ln|y | = u ³′² + C
(that is, u is raised to the 3/2 power)
ln|y | = (3x ² - 1)³′² + C
Solve for y by taking the exponential of both sides:
exp(ln|y |) = exp((3x ² - 1)³′² + C )
y = exp((3x ² - 1)³′²) × exp(C )
y = C exp((3x ² - 1)³′²)
which can be written as
y = C exp(√((3x ² - 1)³))
which makes the answer none of these; this solution can't be expressed as either option given in A or B.

The car they will be using uses 6.3 litre/100km and runs on 50 ppm
diesel which will cost them R17.82/litre. Determine their fuel cost in
cents per kilometre.
(5)
Answer:
[tex]Cost = 112.266[/tex] cent/km
Step-by-step explanation:
Given
[tex]Unit\ cost = R17.82/litre[/tex]
[tex]Rate = 6.3litre/100km[/tex]
Required
The fuel cost in [tex]cent\ per\ km[/tex]
This is calculated using:
[tex]Cost = Unit\ cost * Rate[/tex]
[tex]Cost = R17.82/litre * 6.3litre/100km[/tex]
[tex]Cost = R17.82 * 6.3/100km[/tex]
[tex]Cost = R1.12266/km[/tex]
Multiply by [tex]100[/tex] to get the cost in cents
[tex]Cost = 1.12266 * 100[/tex] cent/km
[tex]Cost = 112.266[/tex] cent/km

MADD (Mother's Against Drunk Drivers) wishes to estimate the proportion of adult drivers that have run at least one red light in the last month. A poll is conducted on a simple random sample of adult drivers and it is found that out of 1251 adult drivers, 641 of them have run at least one red light in the last month. You will be finding a 90% confidence interval for the fraction of adult drivers that run at least one red light in the last month.
Required:
Check that the normality assumptions are met?
Answer:
Normality assumptions are met.
The 90% confidence interval for the proportion of adult drivers that run at least one red light in the last month is (0.4892, 0.5356).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
A poll is conducted on a simple random sample of adult drivers and it is found that out of 1251 adult drivers, 641 of them have run at least one red light in the last month.
This means that [tex]n = 1251, \pi = \frac{641}{1251} = 0.5124[/tex]
Normality assumptions:
We need that: [tex]n\pi \geq 10, n(1-\pi)\geq 10[/tex]
We have that:
[tex]n\pi = 1251*0.5124 = 641[/tex]
[tex]n(1-\pi) = 1261*0.4876 = 610[/tex]
So normality assumptions are met.
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5124 - 1.645\sqrt{\frac{0.5124*0.4876}{1251}} = 0.4892[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.5124 + 1.645\sqrt{\frac{0.5124*0.4876}{1251}} = 0.5356[/tex]
The 90% confidence interval for the proportion of adult drivers that run at least one red light in the last month is (0.4892, 0.5356).
