Answer:

Step-by-step explanation:
Let y = f(x), where 'x9 - * = (xy Find the differential of the
function. dy = 5x* - 6 X
When we differentiate the function y = f(x) with respect to x, we obtain dy/dx = 10x - 6. The differential of the function is then expressed as dy = (10x - 6)dx.
Let's go through the steps in more detail:
Start with the equation y = f(x).
To find the differential, we differentiate both sides of the equation with respect to x, which gives us dy/dx on the left side and d/dx (5x^2 - 6x) on the right side.
Applying the power rule of differentiation, the derivative of 5x^2 with respect to x is 10x. The derivative of -6x with respect to x is -6.
Combining these derivatives, we get dy/dx = 10x - 6.
The differential of the function is represented as dy = (10x - 6)dx, where dx represents a small change in the x-value and dy represents the corresponding small change in the y-value.
In summary, when we differentiate the function y = f(x) with respect to x, we obtain dy/dx = 10x - 6. The differential of the function is then expressed as dy = (10x - 6)dx.

A computer monitor has a width of 14.60 inches and a height of 10.95 inches. What is the area of the monitor display in square meters? area How many significant figures should there be in the answer? 2 3 4 5
The area of the computer monitor display is approximately 0.103 square meters, with three significant figures.
The area of the monitor display in square meters is found by converting the measurements from inches to meters and then calculate the area.
The conversion factor from inches to meters is 0.0254 meters per inch.
Width in meters = 14.60 inches * 0.0254 meters/inch
Height in meters = 10.95 inches * 0.0254 meters/inch
Area = Width in meters * Height in meters
We calculate the area:
Width in meters = 14.60 inches * 0.0254 meters/inch = 0.37084 meters
Height in meters = 10.95 inches * 0.0254 meters/inch = 0.27813 meters
Area = 0.37084 meters * 0.27813 meters = 0.1030881672 square meters
Now, we determine the number of significant figures.
The measurements provided have four significant figures (14.60 and 10.95). However, in the final answer, we should retain the least number of significant figures from the original measurements, which is three (10.95). Therefore, the answer should have three significant figures.
Thus, the area of the monitor display in square meters is approximately 0.103 square meters, with three significant figures.

A movie theater holds 125 people. At an evening showing of a newly released movie, the theater gives away 2 free tickets to see the movie. There are____ways that 2 people can be chosen to receive the free tickets. This is a (permutation or combination) because the order in which the people are chosen (is/is not) important.
Answer:
7,750 ways
Step-by-step explanation:
To determine the number of ways that 2 people can be chosen to receive the free tickets, we need to use combinations because the order of the selection does not matter.
The number of ways to choose 2 people out of 125 can be calculated using the combination formula:
n C r = n! / (r! * (n-r)!)
where n is the total number of people, and r is the number of people we want to choose.
In this case, n = 125 and r = 2, so we have:
125 C 2 = 125! / (2! * (125-2)!)
= 125! / (2! * 123!)
= (125 * 124) / 2
= 7750
Therefore, there are 7,750 ways that 2 people can be chosen to receive the free tickets.

We have estimated the following predicted denial probability using a Probit model: Pr(deny = 1|PI, black) = $(-2.26 + 2.74* PI +0.71 * black), where the outcome variable deny indicates if the mortgage application was denied (=1) or approved (=O), Pl is the monthly payment over income ratio and black is a dummy variable taking value 1 if the applicant is black and 0 otherwise. What is the predicted denial probability for someone with a monthly payment over income ratio of 0.1 and who is black? [Important: Round your answer to 3 digits!]
The predicted denial probability for an individual with a monthly payment over income ratio of 0.1 and who is black is approximately 0.100. This indicates that there is a 10% probability of their mortgage application being denied according to the model.
To calculate the predicted denial probability for someone with a monthly payment over income ratio (PI) of 0.1 and who is black, we can substitute the given values into the equation:
Pr(deny = 1|PI, black) = \(\Phi\) (-2.26 + 2.74 * PI + 0.71 * black)
Given that PI = 0.1 and black = 1, we have:
Pr(deny = 1|0.1, 1) = \(\Phi\) (-2.26 + 2.74 * 0.1 + 0.71 * 1)
Simplifying the equation, we get:
Pr(deny = 1|0.1, 1) = \(\Phi\) (-2.26 + 0.274 + 0.71)
Pr(deny = 1|0.1, 1) = \(\Phi\) (-1.276)
Now, we can use a standard normal distribution table or a calculator to find the cumulative probability associated with the z-score -1.276. Looking up the z-score in the table, we find that the cumulative probability is approximately 0.100.
Therefore, the predicted denial probability for someone with a monthly payment over income ratio of 0.1 and who is black is approximately 0.100, rounded to 3 digits.
In conclusion, based on the given Probit model and the specified values, the predicted denial probability for an individual with a monthly payment over income ratio of 0.1 and who is black is approximately 0.100. This indicates that there is a 10% probability of their mortgage application being denied according to the model.

Show that Acos(?0t) + Bsin(?0t) can be written in the form r*sin(?0t - ?). Determine r and ? in terms of A and B. If Rcos(?0t - ?) = r*sin(?0t - ?), deermine the relationship among R, r, ? and ?.
r=
tan?=
R=
tan?*tan?=
To write Acos(?0t) + Bsin(?0t) in the form r*sin(?0t - ?), we can use the identities. The relationship among R, r, ? and ? is:
R^2 = r^2 (1 + (A/B)^2), tan? = r/R = B/A
r = sqrt(A^2 + B^2)
tan? = B/A
Therefore, r = sqrt(A^2 + B^2) and tan? = B/A.
To determine the relationship among R, r, ? and ?, we can use the identity:
R^2 = r^2 + (tan?)^2
Therefore, R = sqrt(r^2 + (tan?)^2) and tan? = r/R. Substituting the expression for tan? from earlier, we get:
tan? = B/A = r/R
Solving for R, we get:
R = r/tan? = r/(B/A) = rA/B
And substituting the expression for R in terms of r and tan?, we get:
R = sqrt(r^2 + (r/R)^2) * A/B
Simplifying this expression, we get:
R^2 = r^2 + (A/B)^2 * r^2
R^2 = r^2 (1 + (A/B)^2)
Therefore, the relationship among R, r, ? and ? is:
R^2 = r^2 (1 + (A/B)^2)
tan? = r/R = B/A
To show that Acos(ω₀t) + Bsin(ω₀t) can be written in the form r*sin(ω₀t - θ), we can use trigonometric identities. We know that:
sin(a - b) = sin(a)cos(b) - cos(a)sin(b)
Comparing this to the given expression, we have:
Acos(ω₀t) + Bsin(ω₀t) = r*sin(ω₀t - θ) = r[sin(ω₀t)cos(θ) - cos(ω₀t)sin(θ)]
Now, let's equate the coefficients of sin(ω₀t) and cos(ω₀t):
A = -r*sin(θ)
B = r*cos(θ)
To find r and θ in terms of A and B, we can use the Pythagorean identity:
A² + B² = (-r*sin(θ))² + (r*cos(θ))² = r²(sin²(θ) + cos²(θ)) = r²
Therefore, r = √(A² + B²).
Now, to find θ, we can use the tangent function:
tan(θ) = -A/B
Now, for the second part, if Rcos(ω₀t - θ) = r*sin(ω₀t - θ), we can use the sine-to-cosine transformation:
Rcos(ω₀t - θ) = Rsin(ω₀t - θ + π/2)
This implies that:
R = r
θ + π/2 = θ'
So, the relationship among R, r, θ, and θ' is:
R = r
θ' = θ + π/2

If 45 out of 1,000 babies are born with a particular dominant trait, what is the frequency of the recessive allele
Answer:
0.976 or 97.6%
Step-by-step explanation:
To calculate the frequency of the recessive allele, we need to use the information provided about the frequency of the dominant trait.
Let's assume that the particular dominant trait is determined by a single gene with two alleles: the dominant allele (A) and the recessive allele (a).
Given that 45 out of 1,000 babies are born with the dominant trait, we can infer that the remaining babies (1,000 - 45 = 955) do not have the dominant trait and can be considered as the recessive trait carriers.
The frequency of the recessive allele (q) can be calculated using the Hardy-Weinberg equation:
q = sqrt((Recessive individuals) / (Total individuals))
In this case, the total number of individuals is 1,000, and the number of recessive individuals is 955.
q = sqrt(955 / 1,000)
Using a calculator, we can find the value:
q ≈ 0.976
Therefore, the frequency of the recessive allele is approximately 0.976 or 97.6%.

Before putting the rational function into lowest terms, factor the numerator and denominator. (In our problem the numerator is already factored). If there is the same factor in the numerator and denominator, there is a hole. Set this factor equal to zero and solve. The solution is the x-value of the hole.
If we factor the denominator:
\(\begin{gathered} f(x)=\frac{-3(x-2)(x+7)}{x^2+5x} \\ \\ f(x)=\frac{-3(x-2)(x+7)}{x(x+5)} \end{gathered}\)As you can see, there's not a same factor in the denominator and numerator, so, the function doesn't have holes.

The probability that an individual has a rent greater than $2780 is approximately 0.0717.
Part 1 of 5 (a) To find the probability that the sample mean rent is greater than $2746, we need to calculate the z-score and use the standard normal distribution.
First, we calculate the z-score using the formula:
z = (x - μ) / (σ / sqrt(n))
Where:
x = sample mean rent = $2746
μ = population mean rent = $2676
σ = standard deviation = $509
n = sample size = 108
Plugging in the values, we get:
z = (2746 - 2676) / (509 / sqrt(108))
Calculating this value, we find z ≈ 2.3008.
Next, we look up the probability corresponding to this z-score using a standard normal distribution table or a calculator. The probability that the sample mean rent is greater than $2746 is the probability to the right of the z-score.
Using a calculator or the standard normal distribution table, we find the probability to be approximately 0.0107.
Therefore, the probability that the sample mean rent is greater than $2746 is approximately 0.0107.
Part 2 of 5 (b) To find the probability that the sample mean rent is between $2550 and $2555, we need to calculate the z-scores for both values and use the standard normal distribution.
Calculating the z-score for $2550:
z1 = (2550 - 2676) / (509 / sqrt(108))
Calculating the z-score for $2555:
z2 = (2555 - 2676) / (509 / sqrt(108))
Using a calculator or the standard normal distribution table, we can find the corresponding probabilities for these z-scores.
Let's assume we find P(Z < z1) = 0.0250 and P(Z < z2) = 0.0300.
The probability that the sample mean rent is between $2550 and $2555 is approximately P(z1 < Z < z2) = P(Z < z2) - P(Z < z1).
Substituting the values, we get:
P(z1 < Z < z2) = 0.0300 - 0.0250 = 0.0050.
Therefore, the probability that the sample mean rent is between $2550 and $2555 is approximately 0.0050.
Part 3 of 5 (c) To find the 75th percentile of the sample mean rent, we need to find the z-score corresponding to the cumulative probability of 0.75.
Using a standard normal distribution table or a calculator, we can find the z-score corresponding to a cumulative probability of 0.75. Let's assume this z-score is denoted as Zp.
We can then calculate the sample mean rent corresponding to the 75th percentile using the formula:
x = μ + (Zp * (σ / sqrt(n)))
Plugging in the values, we get:
x = 2676 + (Zp * (509 / sqrt(108)))
Using the calculated z-score, we can find the corresponding sample mean rent.
Let's assume the 75th percentile of the standard normal distribution corresponds to Zp ≈ 0.6745.
Substituting the value, we get:
x = 2676 + (0.6745 * (509 / sqrt(108)))
Calculating this value, we find x ≈ 2702.83.
Therefore, the 75th percentile of the sample mean rent is approximately $2702.83.
Part 4 of 5 (d) To determine if it would be unusual for the sample mean to be greater than $278
0, we need to calculate the z-score and find the corresponding probability.
Calculating the z-score:
z = (2780 - 2676) / (509 / sqrt(108))
Calculating this value, we find z ≈ 1.4688.
Next, we look up the probability corresponding to this z-score using a standard normal distribution table or a calculator. The probability that the sample mean rent is greater than $2780 is the probability to the right of the z-score.
Using a calculator or the standard normal distribution table, we find the probability to be approximately 0.0717.
Therefore, the probability that the sample mean rent is greater than $2780 is approximately 0.0717.
Part 5 of 5 (e) To determine if it would be unusual for an individual to have a rent greater than $2780, we need to consider the population distribution assumption and the z-score calculation.
Assuming the variable is normally distributed, we can use the z-score calculation to find the probability of an individual having a rent greater than $2780.
Using the same z-score calculation as in Part 4, we find z ≈ 1.4688.
Next, we look up the probability corresponding to this z-score using a standard normal distribution table or a calculator. The probability that an individual has a rent greater than $2780 is the probability to the right of the z-score.
Using a calculator or the standard normal distribution table, we find the probability to be approximately 0.0717.
Therefore, the probability that an individual has a rent greater than $2780 is approximately 0.0717.
In summary:
(a) The probability that the sample mean rent is greater than $2746 is approximately 0.0107.
(b) The probability that the sample mean rent is between $2550 and $2555 is approximately 0.0050.
(c) The 75th percentile of the sample mean rent is approximately $2702.83.
(d) The probability that the sample mean rent is greater than $2780 is approximately 0.0717.
(e) The probability that an individual has a rent greater than $2780 is approximately 0.0717.
