If Liza takes 120 steps, then the number of steps taken by Pete will be 72.

A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A percentage is a mathematical expression in which two things are equal.

Pete, Lulu, and Liza are walking in the Boston downtown. Each time Pete takes 4 steps, Lulu takes 3 steps. Each time Lulu takes 5 steps, Liza takes 4 steps.

Then the relation between is given as

4 Pete → 4 Lulu

5 Lulu → 4 Liza

Then we have

\(\rm \dfrac{5}{3} \times 4 \ Pete \rightarrow \dfrac{5}{3} \ Lulu \rightarrow 4 \ Liza\)

If Liza takes 120 steps, then the number of the step taken by Pete will be

\(\rm \dfrac{5}{3} \times 4 \ Pete \rightarrow 4 \times 120 \\\\Pete \rightarrow 72\)

The elements in the table are in proportional.

Since for every 3unit increase in x, there is a 7 unit increase in y element. Thus, the elements in the table are in proportional.

When x=0 the value of y=0, when x=3 the value of y=7, and finally when x=6 the value of y=14.

The elements is in proportional because the next element is then defined as the multiple of two of the previous element.

Jahlil initially made 14 pints of ice cream. He gave 1 quart (equivalent to 2 pints) to his neighbor and then made milkshakes with half of the remaining ice cream. As a result, he had 12 pints of ice cream left.

Jahlil started with 14 pints of ice cream. A quart is equivalent to 2 pints, so when he gave 1 quart (2 pints) to his neighbor, he was left with 14 - 2 = 12 pints of ice cream.

With 12 pints remaining, Jahlil decided to make milkshakes using half of the ice cream. Since half of 12 is 6, he used 6 pints of the remaining ice cream to make milkshakes. This means that he utilized half of the original quantity of ice cream.

By giving away 2 pints and making milkshakes with 6 pints, Jahlil effectively used 2 + 6 = 8 pints of the initial 14 pints he made. This leaves him with 14 - 8 = 6 pints of ice cream remaining for other purposes or further distribution.

Answer: 240.25 square units

Step-by-step explanation:

You could take the perimeter already given, and turn this into a rectangle.

Since the left side is blank, this means you add 7 to thirteen to get the measurement of it. It would take a while to explain, and it seems like you want the answer soon.

You end up with a perimeter of 62.

If you get 2 sets of 2 values from this perimeter, you can create a width and height for your "rectangle"

You could turn this into a square even. Divide the perimeter by 4 to get a length of each side.

Each side of your rectangle (now square) is equal to 15.5 units.

Since the formula for area for a rectangle is width times height, multiply 15.5 by itself, and you get an area measure of 240.25 square units.

The probability density function for the uniform distribution over the interval from 25 to 40 is given by f(x) = 5/8 for 25 < x < 40 and f(x) = 0 elsewhere.

In probability theory and statistics, a probability density function (PDF) describes the likelihood of a random variable taking on a specific value within a given range. In this case, we are dealing with a uniform distribution over the interval from 25 to 40. The PDF, denoted as f(x), is defined as 1 divided by the width of the interval, which is 40 - 25 = 15 in this case.

Since the uniform distribution is continuous, the PDF remains constant within the interval and is equal to 1 divided by the width. Therefore, we have f(x) = 1/15 for 25 ≤ x ≤ 40, which means that any value within this range has an equal probability of occurring.

Outside the interval from 25 to 40, the PDF is equal to 0, indicating that the probability of obtaining a value outside this range is zero. This makes sense since the uniform distribution assigns equal probability to each point within the interval but assigns zero probability to values outside of it.

In summary, the probability density function for the uniform distribution over the interval from 25 to 40 is f(x) = 5/8 for 25 < x < 40 and f(x) = 0 elsewhere. This means that any value within the interval has a probability density of 5/8, while values outside the interval have a probability density of 0.

The claim we need to check is that 16 is the 50% of 36.

Recall that if we add 50% and 50%, we should end up with 100%. In our case, we have that our 100% is 36. So, if it was true that 16 is the 50% of 36, then it should happen that if we add 16 with itself, we should get 36.

Note that

Since 16+16 is not 36, it is not true that 16 is the 50% of 36.

Answer:

r = 3.6 , a = 2

Step-by-step explanation:

given that r is inversely proportional to a then the equation relating them is

r = \(\frac{k}{a}\) ← k is the constant of proportion

to find k use the condition when r = 12 , a = 1.5

12 = \(\frac{k}{1.5}\) ( multiply both sides by 1.5 )

18 = k

r = \(\frac{18}{a}\) ← equation of proportion

when a = 5 , then

r = \(\frac{18}{5}\) = 3.6

when r = 9 , then

9 = \(\frac{18}{a}\) ( multiply both sides by a )

9a = 18 ( divide both sides by 9 )

a = 2

The dotplot depicts that Only 12% of the values of x were 64.7 or greater. Because this is such a small percentage it would be surprising to get a sample mean of 64.7 or larger in an SRS of size 20 from a Normal population with μ = 64 and σ = 2.5.

The dotplot shows that only 12% of the simulated sample means were 64.7 or greater. This means that it is unlikely to get a sample mean of 64.7 or greater if the population mean is actually 64. In other words, the evidence suggests that the population mean height is greater than 64 inches.

The dotplot shows the distribution of the sample means of 250 simulated samples of size 20. The population mean is 64 and the population standard deviation is 2.5.

The fact that only 12% of the simulated sample means were 64.7 or greater means that it is unlikely to get a sample mean of 64.7 or greater if the population mean is actually 64.

One significant change was the implementation of the New York State Tenement House Act of 1901, which required new tenement buildings to have adequate ventilation and light, indoor plumbing, and fire escapes.

During the late 19th and early 20th centuries, tenement housing in urban areas was characterized by overcrowding, poor sanitation, and inadequate ventilation.

These conditions led to high rates of disease and mortality among the working-class population that lived in them. To address these issues, the New York City Health Department instituted a series of reforms that required tenement buildings to meet certain design and construction standards.

It also mandated minimum room sizes and set limits on the number of people who could occupy a single room.

These changes helped to improve the living conditions in the worst tenements, reducing the spread of disease and improving the overall health of the city's working-class population.

While tenement housing remained a significant problem in urban areas for many years, the reforms instituted by the Health Department represented an important step towards improving the quality of life for those who lived in these buildings.

Step-by-step explanation:

a. The function G(x) is undefined for x = -3 since division by zero is undefined.

b. The equation of the vertical asymptote is x = -3.

c. The degree of the numerator is 2, since the highest power of x is x². The degree of the denominator is 1, since the highest power of x is x¹. Therefore, the numerator has a larger degree.

d. To find the equation of the oblique asymptote, we can use long division. We divide 2x² by x to get 2x, which we then multiply by x+3 to get 2x²+6x. We subtract this from 2x²+1 to get -6x+1. We then divide -6x by x to get -6, which we multiply by x+3 to get -6x-18. We subtract this from -6x+1 to get 19. Therefore, the oblique asymptote is y = 2x - 6 with a remainder of 19/(x+3).

The function is undefined at x=-3, which also defines the vertical asymptote. The numerator has a larger degree than the denominator. Synthetic division yields an oblique asymptote at y = 2x - 6.

Part I:
a. The function G(x) is undefined when the denominator equals zero. Therefore, the value of x that makes the function undefined is x = -3.

b. The vertical asymptote of the function is defined by the value of x which makes the function undefined, which means the equation of the vertical asymptote is x = -3.

c. The numerator 2x² +1 has a larger degree than the denominator x + 3, as the highest power of x in the numerator is 2, and in the denominator it is 1.

d. Because the degree of the numerator is larger than the degree of the denominator, there is an oblique asymptote. We determine the equation of the oblique asymptote by long division or synthetic division. Here, we use synthetic division and find that the divison gives us 2x - 6 as the quotient. Therefore, the equation of the oblique asymptote is y = 2x - 6.
