Construct a 95% confidence interval for the true average monthly salary earned by all employees of People Plus Pty, if it was found that the average monthly salary earned by a sample of 19 employees of the company was R18 500, with a standard deviation of R1 750. Interpret your answer
We can be 95% confident that the true average monthly salary earned by all employees of People Plus Pty is between R16 234.49 and R20 765.51. This means if created for several samples of the same size taken from the population, would contain the actual population mean.
To construct a 95% confidence interval for the true average monthly salary earned by all employees of People Plus Pty, we can use the following formula:
CI = x ± t(α/2, n-1) * (s/√n)
where:
x = sample mean = R18 500
s = sample standard deviation = R1 750
n = sample size = 19
t(α/2, n-1) = t-score at α/2 and n-1 degrees of freedom
Using a t-table or calculator with 18 degrees of freedom (n-1), we can find the t-score at α/2 = 0.025 to be 2.101.
Plugging in the values, we get:
CI = 18500 ± 2.101 * (1750/√19)
= (16234.49, 20765.51)
Therefore, we can be 95% confident that the true average monthly salary earned by all employees of People Plus Pty is between R16 234.49 and R20 765.51.
This means that if we were to take multiple samples of the same size from the population and construct 95% confidence intervals for each sample mean, about 95% of those intervals would contain the true population mean.

The Huns migrated to the West in groups. There were three sections of the migration: the front, the middle, and the back. There were 3 groups of 5 people leading in the front and the same amount of groups and people at the back of the migration. In the middle of the pack, we have 9 groups of 9 people each. Write an expression and solve for the total number of Huns that migrated to the West. Use exponents in your expression.
The total number of Huns that migrated to the West is 111.
How to calculate the total number of Huns?To find the total number of Huns that migrated to the West, we can use the expression:
Total number of Huns = Number of groups x Number of people per group
For the front and back sections, there were 3 groups of 5 people each, so the total number of Huns in each section is:
3 x 5 = 15
For the middle section, there were 9 groups of 9 people each, so the total number of Huns in the middle section is:
9 x 9 = 81
To find the total number of Huns that migrated to the West, we add up the number of Huns in each section:
15 + 81 + 15 = 111
Therefore, the total number of Huns that migrated to the West is 111.

The second number is five more than the first number. The sum of three times the first and double the second number is 30. Find the numbers.
Answer:
x = 4 and y = 9
Step-by-step explanation:
Let x and y be the two numbers. Also,
Let the first number be x and the second number be y.
Converting the word expressions to an equation we get:
y = x + 5
3x + 2y = 30
Only thing left is to substitute y = x + 5 into the second equation
3x + 2y = 30
3x + 2(x + 5) = 30 (substituting y as x + 5)
3x + 2x + 10 = 30 (multiplying by both x and 5)
5x = 30 - 10 (collecting like terms to one side)
5x = 20
[tex]\frac{5x}{5} = \frac{20}{5}[/tex] (divide both sides by 5 to get the value of x)
x = 4
Now that we know the value of x, we can find y.
y = x + 5
y = 4 + 5
y = 9
If you want to make sure your answer is correct, substitute x and y into the equation.
3x + 2y = 30
3(4) + 2(9) = 30
12 + 18 = 30
30 = 30

How many ways to draw?There are 52 ways to draw the first card from a standard deck of 52 cards. Each card in the deck is distinct, so there are 52 different possibilities for the first card.
The deck consists of 4 suits (diamonds, hearts, spades, and clubs) with 13 cards in each suit. Therefore, there are 13 cards of the spades suit. Since each card is equally likely to be drawn, the probability of drawing a spade as the first card is 13/52 or 1/4.
This is because out of the 52 possible cards, 13 of them are spades. So, regardless of the specific spade that is drawn, there are 13 ways to draw a spade as the first card.

Keilantra was given a large box of 24 chocolates for her birthday. If she eats exactly 3 chocolates each day, how many chocolates would Keilantra have remaining 6 days after her birthday?
Answer: 6 chocolates
Step-by-step explanation:
Keilantra had 24 chocolates to begin with, and she ate six lots of three. so the first step is 6 x 3 = 18. Now that we know how many chocolates Keilantra ate, we need to figure out how many chocolates she has left. So we take our product (18) and we subtract it from the total (24). So we end up with 24 - 18 = 6.
Find the critical points c for the function / and apply the Second Derivative Test (if possible) to determine whether each of
these points corresponds to a local maximum (mar) or minimum (Gmin).
/(x) = 7x° In(3x) (* > 0)
(Use symbolic notation and fractions where needed. Give your answer in the form of a comma separated list, if necessary. Enter
DNE if there are no critical points.)
Cmin=
Cmax=
The critical points of f(x) are x = 0 and x = e^(-1/2) / 3, and x = e^(-1/2) / 3 corresponds to a local minimum of f(x). Cmin = e^(-1/2) / 3 and Cmax = 0.
Taking the derivative of f(x) with respect to x using the product rule and the chain rule, we get:
f'(x) = 14x ln(3x) + 7x
Setting f'(x) equal to zero and solving for x, we get:
14x ln(3x) + 7x = 0
Factor out x:
7x(2ln(3x) + 1) = 0
So either x = 0 or 2ln(3x) + 1 = 0.
If x = 0, then f'(x) = 0 and x is a critical point.
If 2ln(3x) + 1 = 0, then ln(3x) = -1/2 and 3x = e^(-1/2). Solving for x, we get:
x = e^(-1/2) / 3
So e^(-1/2) / 3 is also a critical point.
Now we need to apply the second derivative test to determine whether these critical points correspond to a local minimum or maximum.
Taking the second derivative of f(x), we get:
f''(x) = 14 ln(3x) + 21
For x = 0, we have:
f''(0) = 14 ln(0) + 21
The natural logarithm of zero is undefined, so the second derivative does not exist at x = 0. Therefore, we cannot apply the second derivative test at x = 0.
For x = e^(-1/2) / 3, we have:
f''(e^(-1/2) / 3) = 14 ln(1/e^(1/2)) + 21
= -14/2 + 21
= 7/2
Since the second derivative is positive at this point, we can conclude that x = e^(-1/2) / 3 is a local minimum of f(x).

A man is sitting at a park bench 92 feet away from an office building. The medical examiner and other
investigators have determined that the bullet entered the man's head at an angle of 26° and at about 3. 7 feet
off the ground. If the man was shot from the office building, about how high off of the ground was the shooter
located?
The shooter was located approximately 36.15 feet off the ground.
How high was the shooter located?We can use trigonometry to solve for the height of the shooter.
First, we need to find the horizontal distance from the shooter to the man on the park bench. We can use the angle of 26° and the distance of 92 feet to calculate this distance:
horizontal distance = 92 feet * cos(26°)
horizontal distance = 82.33 feet
Next, we can use the height of 3.7 feet and the horizontal distance of 82.33 feet to find the height of the shooter:
tan(26°) = height difference / horizontal distance
height difference = horizontal distance * tan(26°)
height difference = 82.33 feet * tan(26°)
height difference = 36.15 feet
Therefore, the shooter was located approximately 36.15 feet off the ground.

The only value of x where f'(x) = 0 is x = 0.
Let's find all values of x where the derivative of f(x) = [tex]arcsin(e^(2x) – 2x)[/tex] is equal to 0.
Step 1: Find the derivative f'(x) using the chain rule.
For this, we'll need to differentiate [tex]arcsin(u)[/tex] with respect to u, which is [tex](1/√(1-u^2))[/tex], and then multiply by the derivative of u [tex](e^(2x) – 2x)[/tex]with respect to x. So, f'(x) = [tex](1/√(1-(e^(2x) – 2x)^2)) * d(e^(2x) – 2x)/dx[/tex]
Step 2: Find the derivative of e^(2x) – 2x with respect to x. Using the chain rule and the derivative of [tex]e^u: d(e^(2x) – 2x)/dx = 2e^(2x) – 2[/tex]
Step 3: Combine the derivatives. f'(x) =[tex](1/√(1-(e^(2x) – 2x)^2)) * (2e^(2x) – 2)[/tex]
Step 4: Set f'(x) equal to 0 and solve for x. [tex](1/√(1-(e^(2x) – 2x)^2)) * (2e^(2x) – 2) = 0[/tex]
Since the first part of the product [tex](1/√(1-(e^(2x) – 2x)^2))[/tex] is never 0, we can focus on the second part: [tex]2e^(2x) – 2 = 0[/tex]
Step 5: Solve for x. [tex]2e^(2x) = 2 e^(2x) = 1[/tex]
The only way this is true is when 2x = 0, since [tex]e^0 = 1: 2x = 0 x = 0[/tex]
So, the only value of x where f'(x) = 0 is x = 0.

Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of g(x), including the end behavior, y-intercept, and zeros.
g(x) = (x + 2)(x − 1)(x − 2)
g(x) = (x + 3)(x + 2)(x − 3)
g(x) = (x + 2)(x − 2)(x − 3)
g(x) = (x + 5)(x + 2)(x − 5)
g(x) = (x + 7)(x + 1)(x − 1)
For the g(x) functions provided, here are their key features:
g(x) = (x + 2)(x − 1)(x − 2)
End behavior: As x approaches negative or positive infinity, g(x) approaches positive infinity.
Y-intercept: g(0) = -4
Zeros: x = -2, 1, 2
How to explain the functionRay and Kelsey could both be accurate, all depending on the stated third-degree polynomial function.
It is conceivable for a third-degree polynomial to present up to three zeros, thus corroborating Kelsey's point that the function can have up to three intersection points with the x-axis maximum.

To determine which of the given functions represents a Ferris wheel with the same diameter as The Colossus, we need to use the fact that the diameter of a Ferris wheel is equal to the amplitude of the sinusoidal function that models its height.
The amplitude of the function f(t) = 40 sin (π/45 t) +48 is 40, so the diameter of The Colossus is 40 feet. We need to find the function that also has an amplitude of 40.
Looking at the given answer choices, we see that function g(t) has an amplitude of 40 cos (π/45 t) +50, which is equal to 40. This means that the Ferris wheel represented by function g(t) has a diameter of 40 feet, the same as The Colossus.
Functions h(t), j(t), and k(t) all have amplitudes that are less than 40, so they represent Ferris wheels with smaller diameters than The Colossus.
Therefore, the answer is A.

A person stands on level ground 60 m from the nearest point of a cylindrical tank of radius length 20 m. Calculate:
a- the circumference of the tank
b the percentage of the circumference that is visible to the person
The circumference of the tank is is 125.66m and the percentage of the circumference that is visible to the person is 10.24%.
a) To calculate the circumference of the cylindrical tank, using the formula C = 2πr, where C is the circumference and r is the radius of the tank. In this case, r = 20 m, so:
C = 2π(20 m) ≈ 125.66 m
b) To determine the percentage of the circumference visible to the person, we first need to calculate the angle (in degrees) that subtends the visible arc. This can be done using the inverse tangent function:
angle = atan(opposite/adjacent) = atan(20 m/60 m)
angle ≈ 18.43°
Since the visible arc is symmetrical on both sides, the total angle of the visible arc is twice the calculated angle:
total angle ≈ 36.86°
Now, calculate the percentage of the circumference that is visible by dividing the total angle by 360° and multiplying by 100%:
percentage = (36.86°/360°) × 100% ≈ 10.24%
So, the visible percentage of the circumference to the person is approximately 10.24%.

Find the x
Using quadratic formula, the value of x in the quadratic equation are 1.47 and -0.85
What is the value of x?To find the value of x, we can either use quadratic formula or factorization method.
8x² - 2 - 5x = 8
Let's rewrite the equation properly
8x² - 5x - 2 - 8 = 0
8x² - 5x - 10 = 0
a = 8, b = -5, c = -10
Using quadratic formula;
-b ±[√b² - 4ac / 2a]
-(-5) ±[√(-5)² - 4(8)(-10) / 2(8)]
x = 5+ √345 / 16 or x = 5 - √345 / 16
x = 1.47 or x = -0.85

A company estimates that 0. 5% of their products will fail after the original warranty period but within 2 years of the purchase, with a replacement cost of $500. 0. If they offer a 2 year extended warranty for $33. 00, what is the company's expected value of each warranty sold? Please format your answer using a dollar sign and two decimal points for the cents. For example, if the expected value was 50, please enter it as $50. 0
The expected value of each warranty sold is $2.47.
The expected value of each warranty sold can be calculated by subtracting the cost of the warranty from the expected value of the potential savings on replacement costs.
Let's assume that the company sells 1000 warranties. Then, the expected number of products that will fail within 2 years is:
0.5% of 1000 = 0.005 x 1000 = 5
The expected cost of replacing these products is:
5 x $500 = $2500
Therefore, the expected value of the warranty is:
($2500 - $33 x 1000) / 1000 = $2.47
