The key reason why this investigation's findings are erroneous is sampling bias. In statistics, sampling bias refers to a bias during which a sample is constructed in a way that makes some members of the intended population less likely than others to be included.

A private university's 100 students, 50 men, and 50 women were randomly chosen to participate in a study on how American college students felt about commuting. They were questioned about their daily commuting distance (in minutes) to college. The key reason why this investigation's findings are erroneous is sampling bias.

When certain individuals of a population are consistently more likely to be chosen in a sample than others, this is known as sampling bias. In the medical sciences, it is also known as ascertainment bias. Because sampling bias jeopardizes external validity, particularly population validity, it restricts the generalizability of findings.

To bisect a segment, Jessica should place the compass on one endpoint, open it to a width larger than half of the segment, draw two intersecting arcs with the compass, and draw a straight line through the intersection points to bisect the segment.

To bisect a segment, Jessica should first place the compass on one endpoint of the segment and open it to a width larger than half of the segment. She should then draw an arc that intersects the segment at two points. Next, she should place the compass on the other endpoint of the segment and draw a similar arc that intersects the first arc she drew.

Finally, she should draw a straight line through the two points where the arcs intersect to bisect the segment into two equal parts. This method is based on the concept of congruent triangles, as the two arcs create two congruent triangles with the segment as their base.

The probability that a randomly selected college student will find a parking spot in the library parking lot in less than 3 minutes is found as  `0.7475`. Hence, the option D is correct.

The length of time it takes a college student to find a parking spot in the library parking lot follows a normal distribution with a mean of 2.5 minutes and a standard deviation of 0.75 minute.

We are supposed to find the probability that a randomly selected college student will find a parking spot in the library parking lot in less than 3 minutes.

So, we need to find `P(x < 3)` where `x` is the time taken to find a parking spot in the library parking lot.

Now, z-score will be

`z = (3 - 2.5)/0.75

= 0.67`

By looking at the z-score table, the probability that corresponds to z = 0.67 is 0.2514.

Therefore,

`P(x < 3) = P(z < 0.67)

= 0.2514 + 0.5

= 0.7514

≈ 0.7475 (approx)`

So, the correct option is `0.7475`. Hence, the answer is option D.

Answer:

3. 0

4. n = -2

Step-by-step explanation:

I haven't taken pre-calc but this looks a lot like algebra.

For #3, just plug in -2 for the x values, so:

x^2 + 4x +4

(-2)^2 + 4(-2) + 4

= 4 - 8 + 4

= 0

For #4, move the variables to one side and solve( im not sure what the pi is for tho, or is that a n?):

5n + 6 = -3n - 10

add 3n to both sides

8n + 6 = -10

subtract 6 from both sides

8n = -16

divide both sides by 8

n = -2

The profit function is: 40Q - 350000

The break even point in terms of quantity is: 8750

Break even Revenue is: 875000

Determine the total cost of all purchased units.

Divide the total cost by the number of units purchased to get the cost. Calculate the final price using the sales price formula.

Selling price = cost + profit margin.

As par given that sales =25,000

Selling price =br .100

TVC = br 1500000

T F C=b r 350,000. then

Revenue = 25000 * br. 100

Revenue = br 2500000

cost = T V C + TFC

Cost = br. 1850000

Thus:

Profit = Revenue - Cost

Profit = 2500000 - 1850000

Profit = br. 650000

1) TR = QSp = 100Q

TC= TVC + TFC

TVC= (VC)Q= 1,500,000

VC * 250000 = 1500000

VC =  6O

TC= 60Q + 350000

Profit= Q(Sp - Vc) - Fc

(100 - 60)Q - 350000

40Q - 350000

2. BEq = FC/SP - Vc

= 350000/40

= 8750

4. Break even Revenue = BeQ * Sp = 8750* 100=875000

5. Sales volume = profit + TC= 500000 + 1,850,000= 2350000

Quantity of sales = sale volume / Sp = 2350000/100= 23500

Answer:

A=73

B=17

Step-by-step explanation:

From above, you can see that A+B=90

So I can add my two angles together and have it equal to 90

( 5 x + 8 ) + ( x + 4 ) = 90

5 x + 8 + x + 4=90

6 x + 12 = 90

6 x = 90 − 12

6 x = 78  

x = 13  

So  A = 5 x + 8=5 ( 13 ) + 8 = 65 + 8 = 73  

and  B = x + 4 = 13 + 4 = 17

Just to make sure you are correct, add your A and B together and they should equal to 90  

A + B = 73 + 17 = 90

The confidence multiplier z* for constructing a 97% confidence interval is z* = 2.33

To compute the value of the confidence multiplier z* for constructing a 97% confidence interval, we can use the standard normal distribution table (also known as the z-table). The formula for computing the confidence interval for a population mean (μ) is given by:CI =x ± z*(σ/√n)

Where:x is the sample mean σ is the population standard deviation

n is the sample size

z* is the confidence multiplier

We can use the following steps to calculate z* for a 97% confidence interval:

1: Find the area of the middle region

To find the area of the middle region, we subtract the confidence level from 100% and divide the result by 2. In this case, the confidence level is 97%, so the area of the middle region is:Area of middle region = (100% - 97%) / 2 = 1.5%

2: Find the area to the right of the middle region

To find the area to the right of the middle region, we add the area of the middle region to 50%.

In this case, the area to the right of the middle region is:

Area to the right = 50% + 1.5% = 51.5%

3: Look up the z-score in the z-tableWe can use the z-table to find the z-score that corresponds to an area of 51.5% to the right of the mean.

The closest value we can find is 0.01, which has a z-score of 2.33.

Therefore, the confidence multiplier z* for constructing a 97% confidence interval is z* = 2.33 (rounded to two decimal places).

In the absence of price discrimination, the profit-maximizing conditions would be different, and the resulting prices, quantities, total revenue, total cost, and profit would also be different.

To find the profit-maximizing conditions with third-degree price discrimination, we need to equate the marginal revenue (MR) to the marginal cost (MC) for each market segment.

Given the demand equations and the total cost function:

Market 1: Q1 = 160 - 10P1 or P1 = 16 - 0.1Q1

Market 2: Q2 = 200 - 20P2 or P2 = 10 - 0.05Q2

Total Cost: TC = 120 + 4Q

To find the profit-maximizing prices and quantities, we equate MR to MC for each market segment:

MR1 = MC:

16 - 0.2Q1 = 4

0.2Q1 = 12

Q1 = 60

MR2 = MC:

10 - 0.1Q2 = 4

0.1Q2 = 6

Q2 = 60

Substituting the quantities back into the demand equations, we find:

P1 = 16 - 0.1(60) = 10

P2 = 10 - 0.05(60) = 7

The total revenue (TR) can be calculated by multiplying the price by the quantity for each market segment:

TR = P1 * Q1 + P2 * Q2

TR = (10 * 60) + (7 * 60)

TR = 600 + 420

TR = 1020

The total cost (TC) is given by the total cost function:

TC = 120 + 4Q

TC = 120 + 4(60 + 60)

TC = 120 + 480

TC = 600

Finally, the profit (π) can be calculated by subtracting total cost from total revenue:

π = TR - TC

π = 1020 - 600

π = 420

In the absence of price discrimination, the profit-maximizing conditions would be different, and the resulting prices, quantities, total revenue, total cost, and profit would also be different.

DeMoivre's Theorem is a formula that allows us to raise a complex number to a power. It allows us to calculate powers of complex numbers that aren't necessarily real numbers by rewriting the complex number in polar form. For example, the fourth roots of 16  16i can be written as: zn = r1/n(cos + isin).

When using DeMoivre's Theorem to evaluate either a complex number raised to a power or finding the roots of a complex number, the complex number you are evaluating must be in polar form.What is DeMoivre's theorem?DeMoivre's Theorem is a formula that allows us to raise a complex number to a power. The theorem is a shortcut for calculating powers of complex numbers. DeMoivre's Theorem allows us to calculate powers of complex numbers that aren't necessarily real numbers. By rewriting a complex number in polar form, we can use DeMoivre's Theorem to evaluate a power of the number.

Example:Find the fourth roots of the complex number 16 − 16i. First, we must rewrite 16 − 16i in polar form.

16 − 16i

= 16 (1 − i)

= 16 (cos π/4 − i sin π/4).

Using DeMoivre's theorem, we know that the nth root of a complex number can be written as:

zn = r1/n(cosθ + isinθ)n=1,2,...,n

where z = r(cosθ + isinθ) is the complex number in polar form.

Therefore, the fourth roots of 16 − 16i are: 24(cos π/16 + i sin π/16), 24(cos 9π/16 + i sin 9π/16), 24(cos 17π/16 + i sin 17π/16), and 24(cos 25π/16 + i sin 25π/16).

In summary, a complex number in polar form must be used when applying DeMoivre's Theorem to evaluate either a complex number raised to a power or finding the roots of a complex number.

Answer:

D. no function

Explanation:

We have a function because this graph passes the vertical line test. It is impossible to draw a single vertical line to have it pass through more than one point on the V shaped curve. Any x input leads to exactly one y output.

Even though we have a function, it is not one-to-one. Note how the curve fails the horizontal line test. It is possible to draw a horizontal line and have it pass through more than one point on the curve.

For example, draw a horizontal line through y = 3 and it passes through (-3,3) and (3,3) simultaneously. A one-to-one function is where any y output corresponds to exactly one x input, and vice versa. The output y = 3 corresponds to two different inputs x = -3 and x = 3 at the same time.

Why do we care about one-to-one functions? Well it's to help set up the inverse. The inverse goes the opposite direction of what the original function does. In this case, this function doesn't have an inverse unless we restrict the domain in some way.

The given inequality is,

To solve the inequality.

Answer:

Let us solve the inequality.

Final Answer:

We get the solution as:

Option A

Where y is real number the solution of the expression is y = 5.29, y = -5.29.

Any integer's square root equals that same number, which, when squared, yields the original number.

A square root function is a one-to-one function in mathematics that receives a positive integer as an input and outputs the square root of that number.

The given expression is 3y^2 - 84 = 0.

3y^2 - 84 = 0

Add 84 to both sides of the equation:

3y^2 - 84 + 84= 84

3y^2 = 84

Divide both sides of the equation by 3 and take the square root:

√y² = √28

y = 5.29, y = -5.29

Hence, where y is real number the solution of the expression is y = 5.29, y = -5.29.
