The ratio of boys to girls in a math class is not proportional to the ratio of boys to girls in a science class

154=288

Step-by-step explanation:

Let

x ----> the number of boys

y ----> the number of girls

we know that

The ratio of boys to girls is x/y

we have

Math class

[tex]\frac{x}{y}=\frac{18}{11}[/tex]

Science class

[tex]\frac{x}{y}=\frac{14}{16}[/tex]

equate both ratios

[tex]\frac{14}{16}=\frac{18}{11}[/tex]

Multiply in cross

[tex]14(11)=18(16)[/tex]

[tex]154=288[/tex] ----> is not true

therefore

The ratio of boys to girls in a math class is not proportional to the ratio of boys to girls in a science class

1. Population: All adults with a mortgage provider.

2. Sample size: 1,627.

3. Margin error: Approximately 0.02.

4. Confidence interval (95%): 0.204 to 0.236

5. Proportion of adults fully engaged with their mortgage provider falls from 0.204 to 0.236.

Given that,

Gallup poll conducted in 2015

Sample size: 1,627 adults

Population: All adults with a mortgage provider

Percentage of adults who felt fully engaged with their mortgage provider: 22%

Confidence level: 95%

1. Population: All adults who have a mortgage provider.

2. Sample size: 1,627 adults.

3. Margin of error:

To calculate the margin error,

The sample size (n) and the confidence level.

Given that, the confidence level = 95%,

The margin error can be calculated using the formula:

The Margin of Error [tex]= Z \sqrt{(p (1-p) / n)}[/tex]

Assume a conservative estimation for p = 0.5 (since we don't have the sample proportion), and using a Z-value of 1.96 for a 95% confidence level,
The margin error would be:

The margin of error is,

[tex]1.96\sqrt{(0.5 (1-0.5) / 1627)} \approx 0.02[/tex]

Therefore, the 95% margin error is approximately 0.02.

4. 95% Confidence Interval:

Without the sample proportion, we cannot provide a specific confidence interval.

Assume a conservative estimate of p = 0.5,

Calculate the interval using the formula:

Confidence Interval = Sample Proportion ± Margin of Error

Given that,

The sample proportion is 0.22

The margin error is 0.016,

The 95%  of the confidence interval is,

0.22 ± 0.016 = 0.24 or 0.2

5. Expressing the answer in a meaningful sentence:

With a 95% confidence level,

It can be estimated that the proportion of adults who feel fully engaged with their mortgage provider falls between 0.2 to 0.24.

Step-by-step explanation:

To determine the fraction of total interest owed on a loan after the fifth month of a 12-month loan, calculate the numerator by adding the interest paid in each of the first five months, and the denominator by summing the interest amounts for all twelve months. Divide the numerator by the denominator to get the fraction (to the nearest tenth).

To determine the fraction of total interest paid after the fifth month of a 12-month loan, we can use the Rule of 78. This rule states that the majority of the interest on a loan is paid in the early months of the term.

The formula for the Rule of 78 is:

(n + 5)(n + 4)(n + 3)(n + 2)(n + 1) / (n × (n + 1) × (n + 2) × (n + 3) × (n + 4))

where 'n' represents the number of payments remaining.

In this case, we have 7 payments remaining after the fifth month. Plugging this value into the formula, we get:

(7 + 5)(7 + 4)(7 + 3)(7 + 2)(7 + 1) / (7 × (7 + 1) × (7 + 2) × (7 + 3) × (7 + 4)) = 0.505

Therefore, after the fifth month of a 12-month loan, approximately 50.5% of the total interest has been paid.

Answer:

f(6) = - 4 is incorrect.

Step-by-step explanation:

In the given table the values of x and corresponding values of f(x) are given.

The ordered pairs are (-4,6), (-2,3), (0,-1) and (2,-4).

Now, we have to determine the function y = f(x) from any two of the given ordered pair.

The equation of the function is

[tex]\frac{y - 6}{6 - 3} = \frac{x - (- 4)}{- 4 - (- 2)}[/tex]

⇒ -2(y - 6) = 3(x + 4)

⇒ 2y + 3x = 0 ........... (1)

Now, putting x = 6 in the above equation (1), we get y = - 9

Therefore, f(6) = - 9

Hence, f(6) = - 4 is incorrect. (Answer)

Answer:

Disjoint, because the events cannot occur at the same time.

Step-by-step explanation:

disjoint events are mutually exclusive events.

if a and b are two events then a intersection b will be 0 . they cannot occur at the same time.

here in the given problem let the event A be randomly drawing a jack from a standard deckn of card and evnt B be randomly drawing an ace from a standard deck of card.

since in a same card jack and ace cannot occur they are disjoint events.

therefore randomly drawing a jack from a standard deck of cards  and randomly drawing an ace from a standard deck of cards are disjoint events because the events cannot occur at the same time.

The two events are disjoint because a card from a standard deck cannot be both a jack and an ace at the same time. That is, these events cannot occur simultaneously.

In the given scenario, the two events - randomly drawing a jack from a standard deck of cards and randomly drawing an ace from a standard deck of cards - are disjoint. This is because these are separate and distinct events which cannot occur simultaneously. In terms of probability theory, two events are considered disjoint if the occurrence of one event excludes the possibility of the occurrence of the other event. In a standard deck of cards, a card cannot be both a jack and an ace at the same time.

Find three consecutive integers such that the sum of the first, twice the second and three times the third is -76. What is the number?

Let

x ----> the first consecutive integer

x+1 ---> the second consecutive integer

The equation to represent the number  of umbrellas (u) and ponchos (p) he sold last  week is 5u + 3.5p = 190

Solution:

Given that Karachi earns $5 for each umbrella that he  sells and $3.50 for each rain poncho that he  sells

Thus we can say,

Amount earned from 1 umbrella  = $ 5

Amount earned from 1 rain poncho  = $ 3.50

To find: equation to represent the number  of umbrellas (u) and ponchos (p) he sold last  week.

Let "u" be the number of umbrellas sold

Let "p" be the number of ponchos sold

He earned $190 last week selling  ponchos and umbrellas

Thus we can frame a equation as,

number of umbrellas sold x Amount earned from 1 umbrella + number of ponchos sold x Amount earned from 1 rain poncho = $ 190

[tex]u \times 5 + p \times 3.50 = 190\\\\5u + 3.5p = 190[/tex]

Thus the equation to represent the number  of umbrellas (u) and ponchos (p) he sold last  week is found

To represent the number of umbrellas (u) and ponchos (p) sold by Karachi last week, the equation is 5u + 3.50p = 190.

To represent the number of umbrellas (u) and ponchos (p) sold by Karachi last week, we can set up an equation based on the given information:

5u + 3.50p = 190

This equation represents the earnings from selling umbrellas (at $5 each) and rain ponchos (at $3.50 each) totaling $190. We can use this equation to find the values of u and p.

The width of the rectangle is 14 cm and the length is 23 cm.

Let's assume the width of the rectangle is x cm. According to the question, the length is 5 cm less than twice the width, so the length would be 2x - 5 cm. The perimeter of a rectangle is calculated by adding up the lengths of all its sides. In this case, the perimeter is given as 74 cm, so the equation becomes:

2(x + 2x - 5) = 74

Simplifying the equation, we get:

6x - 10 = 74

Adding 10 to both sides:

6x = 84

Dividing both sides by 6:

x = 14

So the width of the rectangle is 14 cm, and the length is 2(14) - 5 = 23 cm.

Answer:

The height of the astronaut from the center of the Earth is 85865 km.

Step-by-step explanation:

It is assumed that the astronaut will be going towards space, so we have to find out that at what height from the center of the earth would the value of g will be [tex]\frac{g}{180}[/tex].

The weight of astronaut on the surface of Earth 180 pounds.

g=9.81 [tex]m/s^{2}[/tex]

Required value of g'=[tex]\frac{g}{180}[/tex]

g'=[tex]\frac{gR^{2} }{h^{2} }[/tex]

where R=Radius of the Earth

h=Height of the point from the center of the earth

[tex]\frac{g}{180} = \frac{gR^{2} }{h^{2} } \\\\h^{2} =180R^{2} \\h=\sqrt{180}  R\\[/tex]

h=13.42

The value of R is approximately 6400 km.

So, h=85865 km.

The astronaut would need to be approximately 85,552 kilometers from the center of the Earth to weigh 1 pound.

Newton's law of universal gravitation is given by the formula:

[tex]F = G \frac{m_1 m_2}{r^2}[/tex]

Where:

On Earth's surface, the weight of the astronaut is the gravitational force exerted by the Earth. This can also be expressed as:

[tex]Weight = m_1 \cdot g[/tex]

Where [tex]g[/tex] is the acceleration due to gravity (approximately [tex]9.8 \text{m/s}^2[/tex]).

Given that the astronaut weighs 180 pounds on Earth, we use the following relation to find the new distance where the astronaut's weight would be 1 pound:

[tex]180 \text{ pounds} \div r^2 = 1 \text{ pound}[/tex]

[tex]r^2 = 180[/tex]

[tex]r = \sqrt{180}[/tex]

However, we need this distance in terms of the Earth's radius [tex]( R_E )[/tex]. The Earth's radius is approximately 6,371 km.

Let's form the ratio:

[tex]\left( \frac{d}{R_E} \right)^2 = 180[/tex]

[tex]\frac{d}{R_E} = \sqrt{180} \approx 13.42[/tex]

Thus, the astronaut would need to be approximately 13.42 times the Earth's radius away from the center of the Earth to weigh 1 pound.

To convert this to an actual distance:

[tex]d = 13.42 \cdot R_E[/tex]

[tex]d \approx 13.42 \cdot 6371 \text{ km} \approx 85,552 \text{ km}[/tex]

Answer:

Step-by-step explanation:

The red bordered area is the patio. We need to find its area.

We will consider

If this was a square, full red square. Then we find the area of the square.

After that, we will subtract the white part that is not there to create the patio shape.

Hence,

Area of Patio = Area of Square - Area of White Portion

So,

Area of Square is Side * Side

If we look at the coordinates, x goes from 5 to 15, so side is 15 - 5 = 10

also, y goes from 5 to 15, so same, that is 10

Area of Square = 10  * 10 = 100

Now, the small white portion is also a square with length 5 (looking at coordinates),

So,

Area of White Portion = 5 * 5 = 25

Hence,

Area of Patio = 100 - 25 = 75 sq. meters

Jamal's age is 24

Mikes age is 7

so their ages together would equal 31

Answer:

The sum of the ages of Mike and Jamal is 31

Step-by-step explanation:

First we need to translate the questions into mathematical equation and then solve.

Let x be Jamal's age and y be Mike's age.

"Jamal's age is 3 more than 3 times Mike's age" can be written mathematically as;

x =3 + 3y ---------------------------------------------------------------(1)

"Mike's age is 17 years less than Jamal's age" can be written mathematically as ;

y = x - 17  -----------------------------------------------------------------(2)

Substitute equation (1) into equation (2)

y = 3 + 3y - 17

y = 3y - 14

subtract 3y from both-side of the equation

y - 3y = 3y - 3y - 14

-2y = -14

Divide both-side of the equation by -2

[tex]\frac{-2y}{-2}[/tex] = [tex]\frac{-14}{-2}[/tex]

y = 7

Mike is 7 years old

Substitute y = 7 into equation (1)

x = 3 + 3y

   = 3 + 3(7)

   = 3+21

    =24

Jamal is 24 years old

The sum of their ages is = x + y = 24 + 7 = 31

Therefore, The sum of the ages of Mike and Jamal is 31

Answer:

The answer is letter D, credit risk.

Step-by-step explanation:

A bond is considered to be a contract between two occurring parties. It allows companies to borrow money from people (investors). These investors purchase the bond and are given a certain interest for a particular period of time. The rate varies according to the economic situation or the company's standing. This affects the supply and demand for the bond.

Remember that the price of the bond and the interest rate are indirectly proportional. This means that as the price of the bond increases, the interest rate decreases and vice-versa.

In the situation above, Rashid is facing a credit risk as an investor. He has been purchasing bonds from a company that has recently gotten a poor rating. This means that the company is not performing well. This can affect the amount of money (including the interest) that will be paid back to Rashid. There is a chance that some of the amount of money he invested will not be returned to him. It was also mentioned that the bond's interest rate has increased. This means that the bond prices will decrease and thus the number of bond investors will also decrease. The issuer of the bond in this situation can have a hard time paying the investor back.
