Answer:

Step-by-step explanation:

a) P = N 150000

R = 5%

T = 5 years

Plug in the values P,R & T in the  formula

I = PRT

\(I=150000*\frac{5}{100}*4\\\\= 1500 * 5 * 4\\\)

I = N 30000

b) I = N 16100

R = 7%

T = 5 years

\(PRT = I\\\\P*\frac{7}{100}*5=16100\\\\P=16100*\frac{100}{7*5}\)

P= N 46000

Answer:

\( \boxed{ \bold{ \boxed{ \sf{a. \: \: interest \: = \: N \: 30000}}}}\)

\( \boxed{ \bold{ \boxed{ \sf{b. principal \: = \: N \: 46000}}}}\)

Step-by-step explanation:

a. Given,

Principal ( P ) = N 150000

Rate ( R ) = 5 %

Time ( T ) = 4 years

Interest ( I ) = ?

Finding the Interest ( I )

\( \boxed{ \bold{ \sf{interest = \frac{principal \times time \times rate}{100} }}}\)

⇒\( \sf{interest = \frac{150000 \times 4 \times 5}{100} }\)

⇒\( \sf{interest = \frac{3000000}{100}} \)

⇒\( \sf{interest = N \: 30000}\)

Interest = N 30000

------------------------------------------------------------

b. Given,

Interest ( I ) = N 16100

Time ( T ) = 5 years

Rate ( R ) = 7 %

Principal ( P ) = ?

Finding the principal

\( \boxed{ \bold{ \sf{principal = \frac{interest \times 100}{time \times rate}}}} \)

⇒\( \sf{ \frac{16100 \times 100}{5 \times 7} }\)

⇒\( \sf{ \frac{1610000}{35} }\)

⇒N \( \sf{46000}\)

Principal = N 46000

Answer is as follows

Step-by-step explanation:

a. The probability of choosing a blue marble can be found by dividing the number of blue marbles by the total number of marbles in the jar. So the probability of choosing a blue marble is:

P(blue) = 4/18 = 2/9

b. Similarly, the probability of choosing a green marble is:

P(green) = 4/18 = 2/9

c. There are no black marbles in the jar, so the probability of choosing a black marble is 0.

Answer:

Blue marbles: \(\frac{2}{9}\)

Green marble: \(\frac{2}{9}\)

Black marble: \(0\)

Step-by-step explanation:

It is given that a jar contains 4 blue, 4 green, 7 yellow, and 3 red marbles, for a total of 18 marbles in all. To solve for probability, you will put the part of what you are solving for (in this case, a certain color marble) over the whole (which includes all colors of the marble together).

a. What is the probability of choosing a blue marble?

It is given to us that there are 4 blue marbles total in the given jar. Therefore, the fraction of blue marbles/all marbles will be 4/18.

You may be asked to simplify. Simplify fractions by dividing common factors. The common factor in this case will be 2:

\(\frac{(\frac{4}{18})}{\frac{2}{2}} = {\frac{2}{9}\)

\(\frac{2}{9}\) is your probability for blue marbles.

b. What is the probability of choosing a green marble?

It is given to us that there are 4 green marbles total in the given jar. Therefore, the process will be the same as blue, meaning that your answer is 2/9 simplified:

\(\frac{\frac{4}{18}}{\frac{2}{2}} = \frac{2}{9}\)

\(\frac{2}{9}\) is your answer.

c. What is the probability of choosing a black marble?

There are no black marbles in the given set (the colors being blue, green, yellow, and red). Therefore, within the given set, there will be no chance of obtaining a black marble.

\(0\) is your answer.

The median is the middle number in a sorted, ascending or descending, list of numbers

Given credit score  

639 732 790 837 677 744 637 821

First we will arrange data in ascending order

so  ascending order is 637,639,677,732,744,790,821,837

Here total number of terms n= 8

The answer of the given question is , the predicted average retail price of a car in 2003 is $9860.40.and  the car will be worth $814 in the year 2010.

A regression equation is a mathematical formula that is used to describe the relationship between two or more variables. It is typically used in statistical analysis to model the relationship between a dependent variable and one or more independent variables.In simple linear regression, there is only one independent variable, and the regression equation takes the form of a straight line. In multiple regression, there are two or more independent variables, and the regression equation takes the form of a more complex mathematical function.

Using a calculator, we can input the data points into a regression equation to find the line of best fit. Using the given data, we get the regression equation:

y = -1357.4x + 18003.8

where y represents the retail price of a car and x corresponds to the year, with x = 1 representing 1998.

To predict the average retail price of a car in 2003, we need to substitute x = 6 (since 2003 corresponds to x = 6) into the regression equation:

y = -1357.4(6) + 18003.8

y = -8144.4 + 18003.8

y = 9860.4

So, the predicted average retail price of a car in 2003 is $9860.40.

To determine the year when the car will be worth $814, we need to substitute y = 814 into the regression equation and solve for x:

814 = -1357.4x + 18003.8

Simplifying, we get:

-1357.4x = -17189.8

x = 12.65

Rounding up to the nearest whole number, we get x = 13, which corresponds to the year 2010. Therefore, the car will be worth $814 in the year 2010.

In this case, since we have four different time slots for employees, we can use a discrete probability distribution known as the categorical distribution.

To determine the probability distribution for employee break time slots, we need to consider the nature of data and the characteristics of the distribution.

The categorical distribution, also known as the multinoulli or the discrete distribution, is suitable when the outcome can take on one of several distinct categories or states, each with its own probability. In this scenario, the four different time slots can be considered as categories or states, and the probability distribution will provide the likelihood of an employee falling into each specific time slot.

To collect the necessary data, we would need information about the actual break time slots of the employees. We could observe and record the break times for a sample of employees over a specific period. This data collection process would involve noting which time slot each employee chooses for their break. By accumulating this data, we can determine the frequency or proportion of employees choosing each time slot.

Based on this collected data, we can construct the probability distribution for the employee break time slots. The distribution will assign probabilities to each category or time slot, reflecting the likelihood of an employee selecting that particular slot for their break. This information can be useful for various purposes, such as scheduling optimization or resource allocation within the organization.

The probability of NOT drawing a face card from a standard deck of 52 cards is 10 over 13.

First determine the total number of face cards and non-face cards in a standard deck of 52 cards.                                   In a standard deck, there are 12 face cards (3 face cards per suit: Jack, Queen, and King, and 4 suits: Hearts, Diamonds, Clubs, and Spades). This means there are 52 - 12 = 40 non-face cards.

Now, we'll calculate the probability of NOT drawing a face card:
Probability = (Number of favorable outcomes) / (Total number of outcomes)
Probability of NOT drawing a face card = (Number of non-face cards) / (Total number of cards)
Probability = 40 / 52

Simplify the fraction by dividing the numerator and denominator by their greatest common divisor (4):
Probability = (40/4) / (52/4)
Probability = 10 / 13

So, the probability of NOT drawing a face card from a standard deck of 52 cards is 10/13. Your answer: 10 over 13.

The number of jelly beans that fit in a 2001 Chevy Suburban can be calculated by finding the volume of the car's interior and dividing it by the volume of a single jelly bean.

To find the number of jelly beans that fit in a 2001 Chevy Suburban, we first need to calculate the volume of the car's interior. The volume of a rectangular prism is calculated by multiplying its length, width, and height. In this case, the length of the Suburban is 219.3in, the width is 78.8in, and the height is 75.4in.

Using the formula V = lwh, we can calculate the volume:

V = 219.3in * 78.8in * 75.4in

Next, we need to find the volume of a single jelly bean. Since the question does not provide this information, we will assume a standard jelly bean size.

Once we have the volume of the car and the volume of a single jelly bean, we can divide the car's volume by the jelly bean's volume to find the number of jelly beans that fit.

We have to find the value of x for the given equation e^(−x^)−e^x =3. Here we can use a small trick to get the solution. We know that e^-x is the reciprocal of e^x. So we can replace e^-x with 1/e^x. Now we have the equation e^(−x^)−e^x =3 in the form e^x - 1/e^x = 3.

This is a quadratic equation in the form ax^2 + bx + c = 0. Here a = 1, b = 0, c = -3. We can solve this quadratic equation to get the value of x.

Given equation is e^(−x^)−e^x =3.We can replace e^-x with 1/e^x.Now the equation is e^(x) - 1/e^(x) = 3.

Let's take e^x as a variable and solve the equation:e^x - 1/e^x = 3Multiplying both sides by e^x, we get e^x * e^x - 1 = 3e^xNow e^(2x) - 3e^x - 1 = 0.

This is a quadratic equation in the form ax^2 + bx + c = 0. Here a = 1, b = -3, c = -1.

We can solve this quadratic equation using the quadratic formula which is given as:x = [-b ± sqrt(b^2-4ac)]/2a.

Substituting the values, we get:x = [-(-3) ± sqrt((-3)^2-4(1)(-1))]/2(1)x = [3 ± sqrt(13)]/2Hence the value of x is x = [3 ± sqrt(13)]/2.

We can solve the given equation e^(−x^)−e^x =3 using a small trick. We know that e^-x is the reciprocal of e^x. So we can replace e^-x with 1/e^x. Now we have the equation e^(−x^)−e^x =3 in the form e^x - 1/e^x = 3. This is a quadratic equation in the form ax^2 + bx + c = 0.

Donald can type 240 words in 6 minutes. How long will it take him to type a 1000-word essay if he types at the same rate?

This question can be solved by using proportions. The question has already given a proportion you need to fill in, which looks like this:

\(\displaystyle \frac{A}{B} =\frac{x}{1000}\)

As you can see, the denominators are B and 1000, which represents the number of words. That means the number of words will go on the bottom, which leaves you with the number of minutes as the numerator.

Donald can type 240 words in 6 minutes. The number of words, 240, is the denominator, and the number of minutes, 6, is the numerator.

Substitute A and B with these values:

\(\displaystyle \frac{A}{B} =\frac{x}{1000} \rightarrow \frac{6}{240} =\frac{x}{1000}\)

Now you need to cross multiply.

\(1000 \times 6=240 \times x\)

Simplify:

\(6000=240x\)

Lastly, you need to divide both sides by 240 to find the value of x alone. This is because 240 is being multiplied by x, and in order to leave x alone, you must do the opposite of it, which is dividing.

\(\displaystyle \frac{6000}{240} =\frac{240x}{240}\)

\(\displaystyle x=25\)

That means Donald can type 1000 words in 25 minutes. A is also equal to 6, and b is equal to 240.

The probability of the spinner stopping on an even number or a multiple of 3 is 20/30, which simplifies to 2/3.

To calculate the probability of the spinner stopping on an even number or a multiple of 3, we need to count the number of regions on the wheel that satisfy this condition and divide by the total number of regions on the wheel.

First, let's count the number of regions on the wheel that are even numbers.

There are 15 even numbers between 1 and 30: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, and 30.

Next, let's count the number of regions on the wheel that are multiples of 3.

There are 10 multiples of 3 between 1 and 30: 3, 6, 9, 12, 15, 18, 21, 24, 27, and 30.

However, some regions are both even and multiples of 3 (i.e., 6, 12, 18, 24, and 30), so we need to subtract the number of overlapping regions to avoid double-counting.

This gives us a total of 15 + 10 - 5 = 20 regions that satisfy the condition.

Therefore, the probability of the spinner stopping on an even number or a multiple of 3 is 20/30, which simplifies to 2/3.

The number of seventh-graders that must join the club in order to meet the president's wishes is 10.

Since there are 45 eighth graders and 20 seventh graders in a school club and the president of this club wants 40% of the club’s members to be seventh graders, we need to find the number of seventh graders that will be added to the school club to make their percentage 40 %.

Let the number of seventh-graders to be added be x.

So, the new number of seventh-graders is 20 + x and the new number of people in the club is 45 + 20 + x = 65 + x

Thus, the percentage of seventh graders in the club is thus

\(\frac{20 + x}{65 + x} X 100\) %

Since this percentage equals 40 %, we have that

\(\frac{20 + x}{65 + x} X 100\)% = 40 %

\(\frac{20 + x}{65 + x} = \frac{40}{100} \\\frac{20 + x}{65 + x} = 0.4\)

Cross-multiplying we have

\(20 + x = 0.4(65 + x)\)

Expanding the bracket, we have

\(20 + x = 26 + 0.4x\)

Subtracting 20 from both sides we have

\(x = 26 - 20 + 0.4x\\x = 6 + 0.4x\)

Subtracting 0.4x from both sides, we have

\(x - 0.4x = 6\\0.6x = 6\)

dividing both sides by 0.6, we have

x = 6/0.6

x = 10

So, the number of seventh-graders that must join the club in order to meet the president's wishes is 10.
