Answer:

(a) Attached to this response.

(b)

(i) 0 cups = 0.275

(ii) 4 cups = 0.125

(iii) 8 cups = 0.025

Step-by-step explanation:

(a) The frequency and relative frequency table has been attached to this response.

i. The first column, labelled x, is the number of cups of coffee consumed per day.

ii. The second column, labelled f, is the number of people that consumed x cups of coffee per day. It is found by counting the number of occurrences (i.e frequency) of the numbers of the first column, x, in the given data.

For example, 0 in first column appears 11 times in the given data. Also, 5 in the first column appears 4 times in the given data.

iii. The third column, labelled r, is the relative relative frequency of the number of cups of coffee. It is calculated by dividing the frequency of the cups of coffee by the total number of people that consumed it. As shown on the table, it is calculated by dividing the each of the values on the second column by the sum of the values on that same column (second column).

For example, the relative frequency of 2 cups of coffee is given by:

r = 7  ÷ 40 = 0.175

Also, the relative frequency of 4 cups of coffee is given by;

r = 5 ÷ 40 = 0.125

(b) The probability (Pₓ) that a randomly selected person consumed x cups of coffee is given by;

Pₓ = frequency of x ÷ total frequency

This is also the relative frequency of x

Therefore,

(i) The probability (P₀) that a randomly selected person consumed 0 cups of coffee is given by;

the relative frequency of 0 = 0.275

(ii) The probability (P₄) that a randomly selected person consumed 4 cups of coffee is given by;

the relative frequency of 4 = 0.125

(iii) The probability (P₈) that a randomly selected person consumed 8 cups of coffee is given by;

the relative frequency of 8 = 0.025

An architect makes a model of a new house. The model shows a tile patio in the backyard. In the​ model, each tile has length 1/4 in. and width 1/6 in. The actual tiles have length 1/6 ft and width 1/9 ft.
What is the ratio of the length of a tile in the model to the length of an actual​ tile? What is the ratio of the area of a tile in the model to the area of an actual​ tile

Answers

Answer:

The answer is below

Step-by-step explanation:

The model is a tile with length 1/4 in. and width 1/6 in while the actual tile has length 1/6 ft. and width 1/9 ft.

Firstly we have to convert the model length and width from inches to feet.

1 feet = 12 inches

model length =  1/4 in. = 1/4 in * (1/12) ft./in = 1/48 ft.

model width =  1/6 in. = 1/6 in * (1/12) ft./in = 1/72 ft.

Therefore:

Ratio of model length to actual length of tile = (1/48 ft.) / (1/6 ft.) = 1 / 8

Ratio of model length to actual length of tile = (1/72 ft.) / (1/9 ft.) = 1 / 8

Area of model tile = length * width = 1/48 ft. * 1/72 ft. = 1/3456 ft²

Area of actual tile = length * width = 1/6 ft. * 1/9 ft. = 1/54 ft²

Ratio of model area to actual area of tile = (1/3456 ft²) / (1/54 ft²) = 1 / 64

A car company’s profit can be modeled by the equation P = –2x^2 + 44x – 42, where P is the profit in millions of dollars and x is the number of cars sold in thousands.
(a.) How many cars are sold when the company breaks even?
(b.) What is the company’s maximum profit? How many cars sold gives the maximum profit?

Answers

Answer:

a) 1000,21000 are the break even number of cars

b) the maximum profit is 200 at 11000 cars

Step-by-step explanation:

P = –2x^2 + 44x – 42

To break even, P =0

0 = –2x^2 + 44x – 42

Factor

0 = -2( x^2 -22x+21)

0 = -2 ( x-21)(x-1)

Using the zero product property

0 = x-21    0 = x-1

x=21            x=1

Remember that x is the number of cars in thousands

When the profit is maximum is at the vertex

The vertex is 1/2 way between the two zeros

(1+21)/2 = 22/2 = 11

11 cars sold

The maximum profit is

P(11) = –2(11)^2 + 44(11) – 42=--242+484-42=200

The maximum profit is 200

Which equation matches the function shown in the graph?

Answers

The equation matches the function shown in the graph is y= cos (1/4 x ).

The correct option is B.

What is Function?

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).

There are three components that make up a function: a set of inputs, a set of outputs, and a rule that links the elements of the input set to the elements of the output set so that each input is paired with exactly one output.

We have a graph for which we have to find the equation.

Here, the graph is ending at π/2 and x= 1.57 then the value of

x = 2π

x = 6.28

So, the value 1.57 and 6.28 need to be compare.

For that we have to multiply x by 4 then the function will be

Write an equation in slope intercept form of the line with the given characteristics. = through: (-3,1), slope · 2​

Answers

Answer:

y=2x+7

Step-by-step explanation:

Hi there!

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

we are given the slope (2), and a point (-3,1)

we can subsitute 2 as m into the equation

y=2x+b

we need to find b

Since the equation will pass through the point (-3,1), you can use it to solve for b.

substitute -3 as x and 1 as y

1=2(-3)+b

multiply

1=-6+b

7=b

therefore the equation of the line is y=2x+7

Answers

Answer:f(x) = 3x - 7

6 up; 2 right = 3(x-2) - 7 + 6

= 3x - 6 - 7 + 6

= 3x - 7

reflected about y-axis; 7 left = -3(x+7) -7

= -3x - 21 - 7

= -3x - 28

up 5 ; 2 vert stretch = (2)(3x - 7) + 5

= 6x - 14 + 5

= 6x - 9

up 9 ; 4 vert stretch = (4)(3x - 7) + 9

= 12x - 28 + 9

= 12x - 19

Step-by-step explanation:

The transformation of a function may involve any change. The function f(x) stretched vertically by a factor of 2 and translated up by 5 units is (6x - 9).

How does the transformation of a function happen?

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs) etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units, y=f(x+c) (same output, but c units earlier)Right shift by c units, y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + dDown by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)Horizontal stretch by a factor k: y = f(x/k)

Given the function f(x)=3x-7, which can be transformed as shown below.

1. The function f(x) stretched vertically by a factor of 4 and translated up by 9 units.

Vertical stretch → 4(3x - 7) = 12x - 28

Up by 9 Units →  (12x - 28) + 9

g(x) = 12x - 19

2. The function f(x) translated 6 units up and 2 units right

Up by 6 units → (3x - 7) +6 = 3x - 1

2 units Right → 3(x-2) - 1 = 3x - 6 - 1 = 3x - 7

g(x) = 3x - 7

3. The function f(x) reflected about the y-axis and translated 7 units left

Reflected about the y-axis → -3x - 7

7 units left → -3(x+7) - 7 = -3x - 21 -7 = -3x-28

g(x) = -3x-28

4. The function f(x) stretched vertically by a factor of 2 and translated up by 5 units

Stretched vertically by a factor of 2 → 2(3x - 7) = 6x - 14

Translated up by 5 units → 6x - 14 + 5 = 6x - 9

g(x) = 6x - 9

Answers

Answer:

105 yards

Step-by-step explanation:

The other side is Width = 374/17 = 22.

So, the new width is 44 ( and the length is 17/2).

Perimeter = 2(17/2) + 2(44) = 17+88=105 yds.

So, 105 yards.

Mark me as Brainliest if this is correct! I really appreciate it! :D

The perimeter of the new garden is 105 yards

The area of a rectangle is expressed as:

A = lw

w = A/l

w = 374/17

w = 22 yards

The perimeter of the new garden if the width is doubled is expressed as:

P = 2(l + w)

P = 2(17/2 + 2(22))

P = 17 + 88

P = 105 yards

Answer:

●an employer-offered retirement account that accepts contributions from employees and employers - 401(k)

●a tax-deferred retirement savings plan available to employees of some nonprofit - 403(b)

●a tax-advantaged college savings plan- 529 plan

●a tax-advantaged savings account available through employers to pay for qualified medical expenses- health FSA

Step-by-step explanation:

●401(k): Retirement

A 401(k) is one of the most well-known tools for retirement savings. A 401(k) is an employer-sponsored retirement plan that allows employees to contribute money on a pre-tax basis. Your contributions and earnings are not taxed until you start making withdrawals.

●403(b): Retirement

Like 401(k) accounts, a 403(b) is a form of an employer-sponsored retirement account. If you work for a public school, university, or non-profit organization, you may be eligible for a 403(b) account.

With a 403(b), you make contributions before taxes are taken out of your paycheck. You don’t pay taxes on the contributions .

● ROTH IRA: Retirement

A Roth IRA works differently than a Traditional IRA. Your contributions are not tax-deductible, and you make contributions with after-tax dollars. However, Roth IRAs offer a unique advantage: your earnings and withdrawals are tax-free. Roth IRAs have the same contribution limits as Traditional IRAs.

● 529 Plan: Education

A 529 education savings plan is a tool you can use to save for your child’s college tuition and fees. The money you invest can grow over time, and if the money is withdrawn to pay for qualified educational expenses, earnings are not subject to federal income tax. Depending on your state, your contributions may also be tax-deductible.

While 529 plans do not have contribution limits, contributions toward a 529 plan count as gifts and are subject to gift-tax laws.

● Flexible Spending Accounts: Health

Some employer-offered health insurance plans include flexible spending accounts (FSAs). With an FSA, you make pre-tax contributions into a separate account to use for health expenses. You can use your FSA dollars to purchase prescription and over-the-counter medications, pay your deductibles or coinsurance, and purchase medical supplies.
