The change in Kareem's total pay for each copy of Math is fun he sells is $90. Kareem's total pay if he doesn't sell any copies of Math is fun is  $2500.

Total Pay means regular straight-time earnings or base salary, plus payments for overtime, shift differentials, incentive compensation, bonuses, and other special payments, fees, allowances or extraordinary compensation.

Given that, the equation 90x+2500 = y, represents the relation between number of copies (x) Kareem sells and total pay (y) he receives,

We are asked to find, Kareem's total pay if he doesn't sell any copies of History is Fun and the change in Kareem's total pay for each copy of History is Fun he sells,

So, from the equation, 90x+2500 = y,

If we compare this equation with the general equation of the line, i.e. y = mx+c, where m is the slope, which shows 'change', we will get m = 90.

Therefore, the change in Kareem's total pay is $90.

Now, the number of copies he is selling is shown by x, if he sells no copy, then x = 0,

Therefore, Kareem's total pay, for x = 0,

y = 2500+90(0)

y = 2500

Hence, the change in Kareem's total pay for each copy of Math is fun he sells is $90. Kareem's total pay if he doesn't sell any copies of Math is fun is  $2500.

It takes Tara 5 months to pay off the balance.

An interest rate tells you how high the cost of borrowing is, or high the rewards are for saving. So, if you're a borrower, the interest rate is the amount you are charged for borrowing money, shown as a percentage of the total amount of the loan.

Given that, Tara used a credit card to pay for a jacket that costs $150.

The credit card company charges 25% interest each month on the remaining balance.

Now, 25% of 150

25/100 ×150

0.25×150= 37.5

So, total money is 150+37.5

= 187.5

Number of months = 187.5/40

= 4.6875

≈ 5

Therefore, it takes Tara 5 months to pay off the balance.

We do not have strong evidence against the 0.07 claim so, the correct answer is: No, the p-value is over 0.10.

Let's calculate the p-value and compare it to the level of significance (alpha) to determine if there is strong evidence against the 0.07 claim.

Let p be the true proportion of employees arriving late. The null hypothesis is that p = 0.07 and the alternative hypothesis is that p > 0.07.

The sample proportion of employees arriving late is x/n = 23/200 = 0.115. Under the null hypothesis, the sampling distribution of the sample proportion follows a normal distribution with a mean of 0.07 and standard deviation [tex]\sqrt{((0.07 * 0.93) / 200)}[/tex] = 0.0319.

The z-score corresponding to the sample proportion is (0.115 - 0.07) / 0.0319 = 1.41. The p-value is the probability of observing a z-score greater than or equal to 1.41 under the null hypothesis, which can be calculated as P(Z >= 1.41) = 0.078.

Since the p-value is greater than the level of significance alpha (which is typically 0.05 or 0.01), we fail to reject the null hypothesis that the true proportion of employees arriving late is 0.07.

Therefore, we do not have strong evidence against the 0.07 claim so, the correct answer is: No, the p-value is over 0.10.

Answer: To find the minimum point of the curve y = x^2 + 4x - 7, we need to find the vertex of the parabolic function. The x-coordinate of the vertex can be found using the formula:

x = -b / (2a)

where a = 1 (coefficient of x^2), b = 4 (coefficient of x), and c = -7 (constant term). So, we have:

x = -4 / (2 * 1) = -2

The y-coordinate of the vertex can be found by substituting the x-coordinate into the original equation:

y = -2^2 + 4 * -2 - 7 = 4 - 8 - 7 = -11

So, the minimum point of the curve y = x^2 + 4x - 7 is located at the point (-2, -11).

Step-by-step explanation:

The relationship between the resonant wavelength λ and the length of an open-closed tube L for the n=1,3,5, and 7 harmonics follows the general equation λ=(2n+1)L/2n. This means that the nth harmonic has a wavelength that is (2n+1) times the length of the tube divided by 2n.

For example, the wavelength of the 1st harmonic is λ= (21+1) L/21=3L/2, the wavelength of the 3rd harmonic is λ= (23+1) L/23=7L/4, the wavelength of the 5th harmonic is λ= (25+1) L/25=11L/4, and the wavelength of the 7th harmonic is λ= (27+1) L/27=15L/4. Therefore, the algebraic relationship between the resonant wavelength and length of an open-closed tube follows the general equation λ= (2n+1) L/2n, where n is the harmonic number.

Answer:

Step-by-step explanation:

I can explain how the two graphs would look like.

If we are comparing two installment factors with respect to the total amount repaid (T) over time (N), we can plot two separate graphs on the same set of axes. The x-axis would represent the number of months (N) and the y-axis would represent the total amount repaid (T).

For each installment factor, we would plot a line that represents the total amount repaid over time. The shape and slope of each line would depend on the interest rate, the amount borrowed, and the number of payments per year.

The two lines would likely have a similar shape, but different slopes and intercepts. The slope of each line would depend on the interest rate and the amount borrowed, with steeper slopes indicating higher interest rates or larger amounts borrowed. The intercept of each line would depend on the amount borrowed and the number of payments per year.

To compare the two installment factors, we would look at the relative slopes and intercepts of the two lines. If one line has a steeper slope than the other, it would indicate that the total amount repaid increases more rapidly over time for that installment factor. If one line has a higher intercept than the other, it would indicate that the total amount repaid is higher at the beginning of the repayment period for that installment factor.

Overall, by plotting the two graphs on the same set of axes, we can visually compare how the total amount repaid (T) depends on the number of months (N) for both installment factors.

The ecologist needs to carefully choose the size of the sampling region based on the pdf of R.

Sampling is the process of selecting a representative subset of individuals or objects from a larger population to study or analyze.

To ensure that their data is representative of the entire ecosystem, it is important to choose a sampling region that is large enough and well-defined.

In this scenario, an ecologist wishes to mark off a circular sampling region with a fixed radius of 13 meters. However, due to natural variation, the actual radius of the sampling region is a random variable, denoted by R. The probability density function (pdf) of R is given as

=> s(r) = { 1-(13-r)] ¹²,

which means that the probability of a particular value of R is proportional to the area of a circle with that radius.

Now, when the ecologist takes a sample, it is important to consider the effects of this random variation in the sampling region. If the radius of the sampling region is too small, it may not capture the full range of variability in the ecosystem.

On the other hand, if the radius is too large, it may include areas that are not representative of the ecosystem as a whole.

Answer:

Step-by-step explanation:

The solution of second order linear equation DE  (1- tcot t) y - ty y 0 for 0 < t < T is y2(t) = sin(t). There cannot be exist a constant k such that {x^2, e^x} is a set of solutions to the given differential equation.

To check if y1(t) = t is a solution to the given differential equation, we substitute it into the DE and simplify:

(1 - t cot(t))y - t(dy/dt) = (1 - t cot(t))t - t(1) = t - t^2 cot(t) - t = t(1 - t cot(t))

So y1(t) = t is a solution to the DE.

To check if y2(t) = sin(t) is a solution, we substitute it into the DE and simplify:

(1 - t cot(t))y - t(dy/dt) = (1 - t cot(t))sin(t) - t(cos(t)) = sin(t) - t sin(t) (csc(t)) - t(cos(t)) = sin(t) - t tan(t) sin(t) - t(cos(t))

So y2(t) = sin(t) is also a solution to the DE.

To check if y1(t) and y2(t) are linearly independent, we can check if their Wronskian is nonzero. The Wronskian of two solutions y1(t) and y2(t) of a second-order linear differential equation is given by:

W(y1, y2) = y1(t) (dy2/dt) - y2(t) (dy1/dt)

Substituting y1(t) = t and y2(t) = sin(t), we get:

W(y1, y2) = t cos(t) - sin(t)

Since W(y1, y2) is not identically zero (it is zero only at certain values of t), we can conclude that y1(t) and y2(t) are linearly independent.

The general solution to the given differential equation is given by:

y(t) = c1 t + c2 sin(t)

where c1 and c2 are constants determined by the initial or boundary conditions.

Let W(x) be the Wronskian of the solutions y1(x) and y2(x) of the differential equation given by:

(1 - x^2) y'' - 2x y' + k y = 0

Then, we have:

W(x) = y1(x) y2'(x) - y1'(x) y2(x)

Substituting y1(x) = x^2 and y2(x) = e^x, we get:

W(x) = x^2 e^x - 2x e^x - x^2 e^x = -2x e^x

Since we are given that W(0) = 1, we have:

W(0) = -2(0) e^0 = 1

This gives us a contradiction, so there cannot exist a constant k such that {x^2, e^x} is a set of solutions to the given differential equation.

What is probability distribution?

A probability distribution is a mathematical function that describes the likelihood of various variable values. Probability distributions are frequently represented using graphs or probability tables.

a) Since there are 10 possible digits for each of the four positions, there are a total of 10^4 = 10,000 possible sequences of numbers that could be drawn.

Only one of these sequences will be the winning sequence, corresponding to a probability of 1/10,000. If a player wins, the prize is $3,700. Therefore, the probability distribution for a player's winnings is shown in below table.

b) To find the expected winnings, we multiply each possible winning amount by its probability and add the products together:

E(Winnings) = (0) * (9999/10000) + (3700) * (1/10000)
