Suppose Alani could modify option A and still pay off the bike in 5 weeks. Describe the relationship between the down payment and the weekly payments.

Answers

Answer:

y = 5x + 180

Step-by-step explanation:

The question is incomplete. The complete question is stated below:

Alani wants to buy a $360 bicycle. She is considering two payment

options. The image shows Option A, which consists of making an initial down payment then smaller, equal-sized weekly payments. Option B consists of making 6 equal payments over 6 weeks.

A) What factors should Alani take into consideration before deciding

between Option A and Option B?

B) Suppose Alani could modify Option A and still pay off the bike in 5 weeks. Describe the relationship between the down payment and the weekly payments.

The image would be sent as an attachment.

SOLUTION:

We would only be providing answer to question B as it corresponds to the question being asked in brainly.com.

To solve this question, we would apply slope intercept form to get a linear equation:

y = mx + c

m = slope, c= constant

Option A initially involves making an initial down payment together with smaller, equal-sized weekly payments.

Modification of Option A: weekly payment would be done in 5weeks while down payment amount would be assumed to be half of total payment. Also it is assumed there is 0% interest rate.

As it is constant, Let the initial down payment = c

c = 1/2 * total payment

c = 1/2 * $360 = $180

m = 5weeks

y = total amount to be paid for the bike

y = $360

x = amount to be paid weekly after the down payment.

Relationship between down payment and weekly payment:

y = mx + c

mx = y-c

x = (y - c)/ m

y = 5x + c

y = 5x + 180

Final answer:

The relationship between a down payment and weekly payments during any sort of payment plan, including for a bike purchase, is an inverse one. If a down payment is introduced, it can either lower the amount of each weekly payment (with same total payment duration), or reduce the duration of the payments (with same weekly payment rate).

Explanation:

The question posed pertains to the relationship between a down payment and weekly payments when purchasing an item, in this instance, a bike. This is a concept of financial mathematics. Though the information provided in the references talking about burger and bus ticket purchases, it doesn't directly pertain to the student's question. So, let's illustrate with a different example.

Let's consider that the total price of the bike is $500. If Alani's weekly payments total up to $100, considering no down payment, she can indeed pay off the bike in 5 weeks. However, if a down payment is introduced, the total amount remains the same ($500) but it's divided differently. If Alani puts down $200 initially as a down payment, she still has $300 to pay off. Therefore, if she continues with her original plan of $100 weekly payment, she would be able to pay off the remaining amount in 3 weeks, not 5. However, if she still wishes to extend her payments to 5 weeks, she would need to pay less weekly. With the remaining $300 divided over 5 weeks, her weekly payments would reduce to $60.

The key take-away is that the introduction of a down payment reduces the amount payoff balance, and thus can reduce weekly payments if the payoff time remains constant. Alternatively, it can reduce the payoff period with unchanged weekly payments. This illustrates the inverse relationship between a down payment and the subsequent weekly payments.

I found the expected value for the number of boys for a family with five children to be 2.5. I must have made an error because a family with 2.5 boys cannot occur

Answers

Answer:

We are meant to round down fractions of persons to the nearest whole number possible

Step-by-step explanation:

Here we have the question with regards the result of a fraction of a person to a solution of a statistic question.

Where the result is a fraction, the format is, since most solutions to questions in statistics with regards to people pertain to the maximum amount of persons that fit a class, and since it is not technically feasible to account for the next half of the person after getting your result, we have to put down only the number of whole people possible which means as a rule we always round down the decimal or fractions  to the nearest whole number of person

Therefore, you are correct, only that we can put 2 instead of 2.5 as your answer.

The statement does not make sense because the expected value of 2.5 represents the average number

of boys for all the families with five children. In a​ five-child family, half the children are expected to be​ boys, so the expected value of 2.5 is consistent.

Answers

Answer:

Result;

[tex]\int\limits\int\limits_S { \textbf{F}} \, \cdot \textbf{N} d {S} = 32\pi[/tex]

Step-by-step explanation:

Where:

F(x, y, z) = 2(x·i +y·j +z·k) and

S: z = 0, z = 4 -x² - y²

For the solid region between the paraboloid

z = 4 - x² - y²

div F        

For S: z = 0, z = 4 -x² - y²

We have the equation of a parabola

To verify the result for F(x, y, z) = 2(x·i +y·j +z·k)

We have for the surface S₁ the outward normal is N₁ = -k and the outward normal for surface S₂ is N₂ given by

[tex]N_2 = \frac{2x \textbf{i} +2y \textbf{j} + \textbf{k}}{\sqrt{4x^2+4y^2+1} }[/tex]

In a survey of 90 students 20 choose rock.40 chose hip hop 30 chose country. In a school of 360 students how many would be expected to chose hip hop or rock

Answers

Answer:

The students would be expected to choose rock be 80 or students choose hip hop be 160 or choose to country be 120.

Step-by-step explanation:

Given:

In a survey of 90 students 20 choose rock, 40 choose hip hop and 30 choose country.

Now, to find the students expected to choose hip hop or rock or country in a school of 360 students.

Let the number of students expected to choose rock be [tex]x.[/tex]

Let the number of students expected to choose hip hop be [tex]y.[/tex]

Let the number of students expected to choose country be [tex]z.[/tex]

Total number of students = 360.

Now, to get the number of students choosing hip hop or rock or country by using cross multiplication method:

In a survey of 90 students 20 choose rock.

So, 90 is equivalent to 20.

Thus, 360 is equivalent to [tex]x[/tex].

[tex]\frac{90}{20} =\frac{360}{x} \\\\By\ cross\ multiplying\ we\ get:\\\\90x=7200\\\\Dividing\ both\ sides\ by\ 90\ we\ get:\\\\x=80.[/tex]

Thus, the number of students expected to choose rock is 80.

Now,

In a survey of 90 students 40 choose hip hop.

So, 90 is equivalent to 40.

Thus, 360 is equivalent to [tex]y.[/tex]

[tex]\frac{90}{40} =\frac{360}{y} \\\\By\ cross\ multiplying\ we\ get:\\\\90y=14400\\\\Dividing\ both\ sides\ by\ 90\ we\ get:\\\\y=160.[/tex]

Therefore, 160 students expected to choose hip hop.

And,

In a survey of 90 students 30 choose country.

So, 90 is equivalent to 30.

Thus, 360 is equivalent to [tex]y.[/tex]

[tex]\frac{90}{30} =\frac{360}{z} \\\\By\ cross\ multiplying\ we\ get:\\\\90x=10800\\\\Dividing\ both\ sides\ by\ 90\ we\ get:\\\\x=120.[/tex]

Hence, 120 students expected to choose country.

Therefore, the students would be expected to choose rock be 80 or students choose hip hop be 160 or choose to country be 120.

Answers

Answer:

O х= -8/3 or x = 7/2

Step-by-step explanation:

6x² - 5x - 56 = 0

6x² - 21x + 16x - 56 = 0

3x(2x - 7) + 8(2x - 7) = 0

(2x - 7)(3x + 8) = 0

x = 7/2, -8/3

The solutions of the equation 6x² - 5x + 56 using the zero product property is x = -8/3 or x = 7/2.

What are Quadratic Expressions?

Quadratic expressions are polynomial expressions of second degree.

The general form of a quadratic expression is ax² + b x + c.

The given is a quadratic expression,

6x² - 5x = 56

We have to find the solutions using zero product property.

Zero product property states that, if a.b = 0, the either a = 0 or b = 0.

Let 6x² - 5x = 56

6x² - 5x - 56 = 0

Dividing throughout by 6,

x² - 5/6 x - 56/6 = 0

We can factorize it as (x + p)(x + q) such that pq = -56/6 and p + q = -5/6.

We know that,

8/3 × -7/2 = -56/6

8/3 - 7/2 = 16/6 - 21/6 = -5/6

So,

x² - 5/6 x - 56/6 = 0

(x + 8/3) (x - 7/2) = 0

Using zero product property,

(x + 8/3) = 0 or (x - 7/2) = 0

x = -8/3 or x = 7/2

Hence the solutions are x = -8/3 or x = 7/2.

How many times can you expect to roll a 4 if you rolls a fair number cube 120 times? (A fair number cube has 6 sides numbered 1 through 6. If a 4 appears 1 time out of 6 then how many times would it appear out of a 120?)

Answers

Answer:

20times

Step-by-step explanation:

A fair of die has 6sides.

If 4 appears 'once' out of a 6.

Then, 4 will appear 2times out of 12 i.e

6faces = 1time

12faces = 2times.

But remember that we want to know how many times 4 will appear out of a 120

120faces = x times

Since 6faces = 1time (i.e 4 occur one time in six faces)

cross multiplying:

6 × x = 120

x = 120/6

x = 20times

This means 4 will appear 20times out of a 120

Billy and tommy are playing a dice game with a six sided dice. Billy needs to roll a 5 or higher to win the game. What is the probability that billy will rool a 5 or higher

Answers

The answer is 2/6 which would reduce to 1/3 because he could only roll a 5 or higher so he could only roll a 5 or a 6 which is 2 numbers out of 6. Which makes it 2/6 and 2/6 reduces to 1/3 !

The correct option is b) 1/3. Billy's probability of rolling a 5 or higher on a six-sided die is 0.333 or 33.33%.

Probability of Rolling a 5 or Higher

Billy needs to roll a 5 or higher on a six-sided die (with faces numbered 1 through 6) to win the game. Let's calculate the probability.

→ The possible outcomes that satisfy Billy's condition are 5 and 6. Therefore, there are 2 favorable outcomes.

The total number of possible outcomes when rolling a six-sided die is 6.

Calculation

→ Number of favorable outcomes: 2 (rolling a 5 or a 6)

Total possible outcomes: 6

→ Probability (P) = (Number of favorable outcomes) / (Total possible outcomes)

→ P(E) = 2 / 6

          = 1 / 3

          ≈ 0.333

Therefore, the probability that Billy will roll a 5 or higher to win the game is approximately 0.333 or 1/3.

Schadek Silkscreen Printing Inc. purchases plastic cups on which to print logos for sporting events, proms, birthdays, and other special occasions. Zack Schadek, the owner, received a large shipment this morning. To ensure the quality of the shipment, he selected a random sample of 300 cups. He found 15 to be defective.
a. What is the estimated proportion defective in the population?
b. Develop a 95 percent confidenceinterval for the proportion defective.c. Zack has an agreement withhis supplier that he is to return lots that are 10 percent or moredefective. Should he return this lot? Explain your decision.

Answers

Given Information:

Number of defective cups = 15

Total number of cups = 300

Required Information:

a) defective proportion = p = ?

b) 95% confidence interval of defective proportion = ?

Answer:

a) defective proportion = p = 0.05 = 5%

b) 95% confidence interval of defective proportion = (2.5%, 7.5%)

Step-by-step explanation:

The estimated defective proportion is given by

p = Number of defective cups/Total number of cups

p = 15/300

p = 0.05

p = 5%

The confidence interval of defective proportion is given by

[tex]CI = p \pm z\sqrt{\frac{p(1-p)}{n} }[/tex]

Where p is the defective proportion, z is the z-score corresponding to 95% confidence level and n is the total number of cups.

The z-score corresponding to 95% confidence level is 1.96

[tex]CI = 0.05 \pm 1.96\sqrt{\frac{0.05(1-0.05)}{300} }[/tex]

[tex]CI = 0.05 \pm 1.96(0.01258)[/tex]

[tex]CI = 0.05 \pm 0.025[/tex]

[tex]Upper = 0.05 + 0.025 = 0.075[/tex]

[tex]Lower = 0.05 - 0.025 = 0.025[/tex]

[tex]CI = (0.025, 0.075)[/tex]

CI = (2.5%, 7.5%)

So that means we are 95% confident that the defective proportion is between 2.5% to 7.5%.

Zack should not return this lot since the defective percentage is below 10%

Final answer:

Zack Schadek calculated the proportion of defective cups to be 5%, and then he developed a 95% confidence interval which did not surpass the 10% defectivity threshold set by his agreement with the supplier. Therefore, he should not return the lot based on this sample's data.

Explanation:

To answer the question of whether Zack Schadek should return the shipment of cups, we first need to calculate the estimated proportion defective in the population. We do this by dividing the number of defective cups by the total number of cups in the sample. In this case, it is 15 defective cups out of 300, which equals 0.05 or 5%.

Next, we will develop a 95 percent confidence interval for the proportion defective. To construct this confidence interval, the binomial distribution can be approximated by a normal distribution since np and n(1-p) are both greater than 5.  Plugging in the values, we obtain the confidence interval.

Finally, considering Zack's agreement with his supplier to return lots that are 10% or more defective, the calculated proportion defective is well below 10%. Additionally, since the confidence interval does not include 10% or higher values, Zack should not return the lot based on the data from his sample.

Toby invested £4500 for 2 years in a saving accounts . he was paid 4% per annum compound interest .

How much did Toby have in his saving account after 2 years ?

Answers

Final answer:

Toby will have £4867.20 in his savings account.

Explanation:

To determine how much Toby will have in his savings account after 2 years with a 4% per annum compound interest rate, we can use the formula for compound interest:

A = P(1 + r)ⁿ

Where:

A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (decimal).n is the number of years the money is invested.

Given:

Toby's initial investment (P) is £4500.The annual interest rate (r) is 4%, or 0.04 when expressed as a decimal.The money is invested for n = 2 years.

Using these values in the formula:

A = £4500(1 + 0.04)²

A = £4500(1.04)²

A = £4500(1.0816)

A = £4867.20

Therefore, Toby will have £4867.20 in his savings account after 2 years.

8x + 7 = 2x + 37 ????

Answers

Answer: 5

Step-by-step explanation:Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

7 + 8x + -2x = 37 + 2x + -2x

Combine like terms: 8x + -2x = 6x

7 + 6x = 37 + 2x + -2x

Combine like terms: 2x + -2x = 0

7 + 6x = 37 + 0

7 + 6x = 37

Add '-7' to each side of the equation.

7 + -7 + 6x = 37 + -7

Combine like terms: 7 + -7 = 0

0 + 6x = 37 + -7

6x = 37 + -7

Combine like terms: 37 + -7 = 30

6x = 30

Divide each side by '6'.

x = 5

Simplifying

x = 5

8x + 7 = 2x + 37

1. subtract 7 from the 7 on the left and 37 on the right

8x+7 (-7)= 2x + 37 (-7)

8x =2x +30

2.subtract 2x from 2x on the right and 8x on the left

8x -2x = 2x -2x +30

6x= 30

3.divide 6 from each side

6x/6 = 30/6

6 divided by 6 cancels out

30 divided by 6 is 5

Choose 3 ratios in simplest form. 3:9

Answers

Answer:

Step-by-step explanation:

1:3

6:18

9:27

Final answer:

To choose 3 ratios in the simplest form, you must simplify the given ratios by dividing all the numbers by their greatest common divisor or the smallest among them. In genetics and chemistry, these simplified ratios are used to predict genetic outcomes and determine molecular compositions.

Explanation:

Choosing 3 ratios in the simplest form involves simplifying the given ratio. A ratio compares two quantities and can be written in various forms such as fractions, with a colon, or with the word 'to.' For example, 3:9, when simplified, becomes 1:3 as both numbers can be divided by 3. To express ratios as whole numbers or in the simplest form, divide all the numbers by the smallest number among them. For example, the ratio of 55:10:12 simplifies to 5.5:1:1.2, and when expressed as whole numbers, it becomes 5:1:1. In the subject of genetics, ratios such as 9:3:3:1 are used to predict outcomes based on genetic theory, and we can use data to test these ratios.

In chemistry, the mole ratio can be determined by dividing the molar amounts by the smallest molar amount. This is used to determine the ratio between different elements in a compound. For instance, if the molar amounts of elements in a compound were 0.03567 mol of Oxygen, 0.1070 mol of Carbon, and 0.2140 mol of Hydrogen, dividing each by the smallest molar amount of 0.03567 would give us a ratio that should then be expressed as whole numbers.

Identify the surface whose equation is given. rho2(sin2(φ) sin2(θ) + cos2(φ)) = 49

Answers

Answer:

The surface is a cylindrical surface with radius 7 units

Step-by-step explanation:

The equation is properly written as:

[tex]\rho^{2} (sin^{2} \phi sin^{2} \theta + cos^{2} \phi) = 49[/tex]

The above equation takes the form [tex]y^{2} + z^{2} = r^{2}[/tex]

Where [tex]y^{2} = \rho^{2} sin^{2} \phi sin^{2} \theta[/tex]

[tex]y = \rho sin \phi sin \theta[/tex]

and [tex]z^{2} = \rho^{2}cos^{2} \phi[/tex]

[tex]z = \rho cos \phi[/tex]

[tex]r^{2} = 49[/tex]

r = 7 units

The surface is a cylindrical surface with radius 7 units

Nancy's Cupcakes recorded how many cupcakes it recently sold of each flavor.​

​chocolate cupcakes 2
​pistachio cupcakes ​ 1
​banana cupcakes ​ 5
​pumpkin cupcakes ​ 6

​​Considering this data, how many of the next 21 cupcakes sold would you expect to be pumpkin cupcakes?​
A
9
B
7
C
6
D
3
Part B
What is probability of a chocolate cupcakes being sold?
​ Probability (chocolate cupcakes) =
%
Note: Write your answer as a percentage rounded to the nearest whole number.

Answers

Answer:

Part A; 9

Part B; 14%

Step-by-step explanation:

Part A;

Knowing that pumpkin cupcake = 6

Total = add all the cupcake which is 2+1+5+6 = 14

Cross multiply

[tex]\frac{6}{14}=\frac{x}{21}[/tex]

6*21 = 126

126/14 = 9

Hence, Next 21 cupcakes sold, 9 cupcake will be pumpkin cupcake

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

Part B;

The probability of a chocolate cupcake being sold would be equal to the amount of chocolate cupcakes divided by the total number of cupcakes.

= 2/(2+1+5+6)

= 2/14

= 1/7.

We convert 1/7 to a percent.

When rounded to the nearest whole percent, we get the probability as 14%.

[RevyBreeze]

Final answer:

In the next 21 cupcakes sold, we would expect approximately 9 to be pumpkin cupcakes based on the past data. The probability of a chocolate cupcake being sold, based on this data, is approximately 14%.

Explanation:

The question is about predicting the expected number of pumpkin cupcakes sold based on past data and calculating the probability of a chocolate cupcake being sold.

Part A: In total, 2+1+5+6 = 14 cupcakes were sold. Out of these, 6 were pumpkin cupcakes which is approximately 43% of the total (6/14 = 0.43). If we project this percentage to the next 21 cupcakes, we would expect approximately 9 pumpkin cupcakes to be sold (0.43 * 21 = 9).

Part B: Out of the 14 cupcakes sold, 2 were chocolate. To find the probability of a chocolate cupcake being sold, you divide the number of chocolate cupcakes (2) by the total number of cupcakes (14) which is approximately 14%. So, the Probability (chocolate cupcakes) = 14 %.
