(q023) what data collection method was primarily used by mary pattillo to study the influx of black professionals into a chicago neighborhood where many lower-class blacks already lived?

Answer:

-5 5/8

Step-by-step explanation:

A negative minus a positive is essentially a negative plus a negative! The two values will add on top of each other to create a larger negative number.

I'd recommend turning the mixed numbers into improper fractions: 25/8 and 5/2. Then, make sure their denominators are equal by multiplying 5/2 by a "big one" or 4/4. This should get you 20/8.

Now, solve for -25/8 - 20/8 to get -45/8. Turn that number into a mixed number, and you have your answer!

Answer:

Amount set aside for food = 0.12 × 4,000

Step-by-step explanation:

His net pay = $4,000

His budget

Food = 12% of his budget

Assume $4,000 is his budget

Then,

Food = 12% of $4,000

= 12/100 × 4,000

= $480

The Equation is

Amount set aside for food = 0.12 × 4,000

The equation would be set up as follows:

\(\begin{aligned} \rm {Amount \: for \: food \: pay} &= \dfrac{12 \times 4000}{100}\\&= \$\:480 \end{aligned}\)

Given that:

Amount of net pay is $4,000

Percentage of budget used for food is 12%

To calculate the amount towards food, we'll take out 12% of amount of net pay which is $4,000.

It would be written symbolically as:

\(\begin{aligned} \rm {Amount \: for \: food \: pay} &= \dfrac{12 \times 4000}{100}\\&= \$\:480 \end{aligned}\)

Thus, amount for food pay is in total $ 480, and is calculated by above equation.

The correct answer is D. f(x) = 11x - 4 and g(x) = (x + 4)/11

To determine which pair of functions are inverses of each other, we need to check if the composition of the functions results in the identity function, which is f(g(x)) = x and g(f(x)) = x.

Let's test each option:

Option A:

f(x) = x/2 + 15

g(x) = 12x - 15

f(g(x)) = (12x - 15)/2 + 15 = 6x - 7.5 + 15 = 6x + 7.5 ≠ x

g(f(x)) = 12(x/2 + 15) - 15 = 6x + 180 - 15 = 6x + 165 ≠ x

Option B:

f(x) = ∛3x

g(x) = (x/3)^3 = x^3/27

f(g(x)) = ∛3(x^3/27) = ∛(x^3/9) = x/∛9 ≠ x

g(f(x)) = (∛3x/3)^3 = (x/3)^3 = x^3/27 = x/27 ≠ x

Option C:

f(x) = 3/x - 10

g(x) = (x + 10)/3

f(g(x)) = 3/((x + 10)/3) - 10 = 9/(x + 10) - 10 = 9/(x + 10) - 10(x + 10)/(x + 10) = (9 - 10(x + 10))/(x + 10) ≠ x

g(f(x)) = (3/x - 10 + 10)/3 = 3/x ≠ x

Option D:

f(x) = 11x - 4

g(x) = (x + 4)/11

f(g(x)) = 11((x + 4)/11) - 4 = x + 4 - 4 = x ≠ x

g(f(x)) = ((11x - 4) + 4)/11 = 11x/11 = x

Based on the calculations, only Option D, where f(x) = 11x - 4 and g(x) = (x + 4)/11, satisfies the condition for being inverses of each other. Therefore, the correct answer is:

D. f(x) = 11x - 4 and g(x) = (x + 4)/11

Answer:

4 hours

Step-by-step explanation:

d = r * t

t = t       for the second car. This is the time to catch the first car.

t = t + 2 for the first car

r = 50 km/h for the first car

r = 75 miles per hour.

The trick to this question is realizing that both cars have to go the same distance.

50*(t + 2) = 75 * t             Remove the brackets

50 t  + 100 = 75t              Subtract 50t from both sides

100 = 75t - 50 t

100 = 25t                         Divide by 25

100/25 = t

t = 4 hours.

What this is telling you is that the faster car will take 4 hours to catch the slower one.

A producer has an absolute advantage over another if they can create the same amount of output with less input or more input with the same amount of output.

If farmer A uses less inputs to produce 100 bushels of wheat than farmer B in this scenario, farmer A will always have the upper hand in producing wheat. Technology, skill, experience, or resource access disparities could be at blame for this. It is crucial to understand that a producer's absolute output advantage does not imply that they are more effective or successful. The producer who has the greatest production advantage may decide to focus exclusively on manufacturing the good in which they excel and trade with others for the goods.

Yes, because both figures are rectangles and all rectangles are similar. Option B is correct option.

According to the statement

We have given that the two rectangles EFGH and ABCD and we have show that the these rectangles Are dilation at origin or not.

So, According to the given diagram

Yes, the rectangle EFGH is a result of dilation of rectangle ABCD with a center of dilation of rectangle at the origin.

Also The scale factor of the dilation is greater than one as the image is bigger than the pre-image i.e. there is a stretch.

The scale factor could be calculated by the ratio of the sides of the image to the pre-image rectangle.

According to the diagram In Rectangle ABCD:

Its vertices have coordinates A(-3,3), B(3,3), C(3,0) and D(-3,0).

Now consider rectangle EFGH:  

Its vertices have coordinates E(-4,4), F(4,4), G(4,0) and H(-4,0).

Hence the scale factor is becomes from these values is:

EF/AB = EH/AD = FG/BC = HG/DC = 4/3.

Hence the scale factor becomes 4/3.

Also

∠A=∠B=∠C=∠D=∠E=∠F=∠G=∠H=90°

The divergence of the vector field F(x, y, z) = (5x^2 + 7 - sin(xz))i + 0j + (5x^2 + 7 - sin(xz))k is 20x - 2zcos(xz).

To find the divergence of the vector field F(x, y, z) = (5x^2 + 7 - sin(xz))i + 0j + (5x^2 + 7 - sin(xz))k, you need to take the divergence operator (∇ · F).

The divergence of a vector field in Cartesian coordinates is given by the following formula:

∇ · F = (∂Fx/∂x) + (∂Fy/∂y) + (∂Fz/∂z),

where Fx, Fy, and Fz are the x, y, and z components of the vector field F, respectively.

In this case, we have:

Fx = (5x^2 + 7 - sin(xz)),

Fy = 0, and

Fz = (5x^2 + 7 - sin(xz)).

Taking the partial derivatives, we get:

∂Fx/∂x = 10x - zcos(xz),

∂Fy/∂y = 0, and

∂Fz/∂z = 10x - zcos(xz).

Now, substituting these derivatives into the divergence formula, we have:

∇ · F = (10x - zcos(xz)) + 0 + (10x - zcos(xz)).

Simplifying further, we get:

∇ · F = 20x - 2zcos(xz).

Therefore, the divergence of the vector field F(x, y, z) = (5x^2 + 7 - sin(xz))i + 0j + (5x^2 + 7 - sin(xz))k is 20x - 2zcos(xz).

Answer:

The correct Instantaneous Rate of Change of R(x)=2x³+5 at x=150.

Marginal Revenue is the extra revenue created by selling one more unit of a good or service.

To find marginal revenue,

we need to take the first derivative of revenue with respect to the quantity of the good sold.

The demand function of the company selling sweatshirts is:

p(x)= 2x³ + 5

Therefore, the revenue function is R(x) = xp(x) = x(2x³ + 5) = 2x⁴ + 5x.

We need to calculate the marginal revenue at x = 500 which means x = 150 (because x is the number of sweatshirts sold in hundreds)

Let's find the first derivative of R(x) with respect to x.

Using the Power Rule, we have:

R'(x) = 8x³ + 5

Now, we need to find the value of R'(150) which is the instantaneous rate of change of revenue at x = 500

(because x = 150)

R'(150) = 8(150)³ + 5

= 2,025,005

Therefore, the correct solution is:

Instantaneous Rate of Change of R(x)=2x³+5 at x=150.

The probability that a randomly selected box of cold medicine will cost more than $15 is approximately 0.8413.

To find the probability, we need to calculate the area under the normal distribution curve to the right of $15. We can use the z-score formula to standardize the value of $15 and then look up the corresponding area in the standard normal distribution table or use statistical software.

First, we calculate the z-score:

z = (x - μ) / σ

where x is the value ($15), μ is the mean ($17), and σ is the standard deviation ($4.5).

z = (15 - 17) / 4.5 = -0.4444

Using the standard normal distribution table or a calculator, we find that the area to the left of z = -0.4444 is approximately 0.3581. Since we want the area to the right of $15, we subtract this value from 1 to get the probability of the box costing more than $15:

P(X > $15) = 1 - 0.3581 = 0.6419

Therefore, the probability that a randomly selected box of cold medicine will cost more than $15 is approximately 0.6419 or 64.19%.

Therefore, a specific value cannot be provided without more information about the population being studied.

However, according to statistics from the United States Census Bureau, the estimated probability of a first marriage ending in divorce by the 20th wedding anniversary is about 52%. This suggests that the odds of a woman getting divorced from her first marriage before age 40 are relatively high.

It's worth noting that divorce rates and probabilities can vary widely based on factors such as age, education level, income, and race/ethnicity. Additionally, divorce is a complex and often emotionally charged issue that is influenced by a wide range of individual and societal factors.
