Explanation:

Let's assume these are the different prices of one (1) gallon of paint for three different brand name and choice of colors:

1. Delux brand: Red = $19 per gallon

2. Golden sun: White = $15 per gallon

3. Luxury: Green = $20 per gallon.

Based on the data above, Mang Jose's budget could be drafted:

1. if he chooses the Delux brand/color red, then he will need approximately 11 gallons of the paint (2700/250 square fit) = 10.8, which would cost = $209 (11*$19).

2. if he chooses the Golden sun brand/color white then he will need approximately 11 gallons of paint  (2700/250 square fit) = 10.8, which would cost = $165 (11*$15).

3. if he chooses the Luxury brand/color green then he will need approximately 11 gallons of paint  (2700/250 square fit) = 10.8, which would cost = $220 (11*$20).

Answer:

The mean of C is 170 households

The standard deviation of C, is approximately 5 households

Step-by-step explanation:

The given parameters are;

The percentage of households in the United States that had a computer in 2014 = 85%

The size of the randomly selected sample in 2014, n = 200

The random variable representing the number of households that had a computer = C

Therefore, we have;

The probability of a household having a computer P = 85/100 = 0.85

Let

Therefore;

The mean (expected) number in the sample, μₓ, = E(x) = n × P is given as follows;

μₓ = 200 × 0.85 = 170

The mean of C = μₓ = 170

The variance, σ² = n × P × (1 - P) = 200 × 0.85 × (1 - 0.85) = 25.5

Therefore;

The standard deviation, σ = √(σ²) = √(25.5) ≈ 5.05

The standard deviation of C, σ ≈ 5 households (we round (down) to the nearest whole number)

The mean and the standard deviation of C are 170 and 5.05 respectively

The given parameters are:

[tex]\mathbf{n = 200}[/tex] -- the sample size

[tex]\mathbf{p = 85\%}[/tex] -- the proportion of household that had a computer

(a) The mean

This is calculated as:

[tex]\mathbf{\bar x = np}[/tex]

So, we have:

[tex]\mathbf{\bar x = 200 \times 85\%}[/tex]

[tex]\mathbf{\bar x = 170}[/tex]

(b) The standard deviation

This is calculated as:

[tex]\mathbf{\sigma = \sqrt{np(1 - p)}}[/tex]

So, we have:

[tex]\mathbf{\sigma = \sqrt{170 \times (1 - 85\%)}}[/tex]

[tex]\mathbf{\sigma = \sqrt{170 \times 15\%}}[/tex]

[tex]\mathbf{\sigma = \sqrt{25.5}}[/tex]

Take square roots

[tex]\mathbf{\sigma = 5.05}[/tex]

Hence, the mean and the standard deviation of C are 170 and 5.05 respectively

Answer:

Adam's container

Step-by-step explanation:

Given

Adam

[tex]Weight = 3.5\ oz[/tex]

[tex]Amount = \$8.75[/tex]

Macro

[tex]Weight = 3.75\ oz[/tex]

[tex]Amount = \$9.75[/tex]

Required

Determine the better buy

First, we need to determine the unit cost per oz of each

i.e.

[tex]Unit\ Cost = \frac{Amount}{Weight}[/tex]

For Adam:

[tex]Unit\ Cost = \frac{8.75}{3.5}[/tex]

[tex]Unit\ Cost = 2.5[/tex]

For Marco:

[tex]Unit\ Cost = \frac{9.75}{3.75}[/tex]

[tex]Unit\ Cost = 2.6[/tex]

The better buy of both is the one with the smaller unit cost.

Since 2.5 < 2.6, we can conclude that Adam's container is a better buy

Answer:

Step-by-step explanation:

Let the number of hours Nick does the job alone to be x - 3 hours

Hence, in 1 hour, Nick has done 1/x - 3

Together they complete the job in 9 hours

Hence, let's represent the job as 1

9/x + 9/x - 3 = 1

Multiply through by (x)(x-3)

9(x- 3) + 9(x) = 1

9x - 27 + 9x = (x)(x-3)

-27 = x² - 3x

x² - 3x +27 = 0

Answer:

360ft^2

Step-by-step explanation:

We know that the height is always 8 ft. So lets find the area of two of the 4 walls.

We multiply by 2 because there are two of the same wall.

2(8ft x 10ft) = 160ft^2

Now lets find the area of the other wall.

2(8ft x 15ft) = 240ft^2

Now we add it up

160 + 240 = 400

400ft^2

But wait! We aren't done yet! We still have to subtract out the door and window which is 60ft^2.

400 - 60 = 360

360ft^2

Answer:

y = 4x + 16

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4, thus

y = 4x + c ← is the partial equation

To find c substitute (- 8, - 16) into the partial equation

- 16 = - 32 + c ⇒ c = - 16 + 32 = 16

y = 4x + 16 ← equation of line

Answer:

There is no slope, it is undefined and the line would continue to go up from the position x= -9

Given:

Perimeter of the triangle = 99 ft

Length of two sides are 20 ft and 42 ft.

To find:

The length of missing side.

Solution:

Let the missing side be x.

Perimeter of a triangle is the sum of all sides of that triangle.

[tex]x+20+42=99[/tex]

[tex]x+62=99[/tex]

Subtract 62 from both sides.

[tex]x=99-62[/tex]

[tex]x=37[/tex]

Therefore, the missing side of the triangle is 37 ft.

− 3/4 is not an integer but a a rational number.

A rational number is simply a number that can be written as a fraction with both the numerator and denominator being integers (where the denominator's not zero). For instance lets consider 3/4 as an example. It can be expressed as the fraction 3/4, where 3 and 4 are both integers.

On the hand an integer is a number that is not, in the form of a fraction. In the case of 3/4 it cannot be classified as an integer since it represents a fraction, than a whole number.

How many pumkind does the farm have left?

Total pumpkins left = Total pumpkins available + total pumpkins brought

= 242 + 12

= 254

Total pumpkins left = 254

Step-by-step explanation:

v=-2

I found this because since it is given that -2v+4=8; If v=-2 then the equation is true, because -2(-2) + 4 = 8. So since v=-2, plug in -2 into v of 3v-10; which would be (3(-2))-10, which is equal to -16.

27.5 units^2

Step-by-step explanation:

Total area = Area of triangle ILH + Area of parallelogram JKLI

Area of triangle ILH

= 12.5 units^2

Area of parallelogram JKLI

Total area

= Area of triangle ILH + Area of parallelogram JKLI

B.) The horizontal asymptote y = 11.95 represents that the cost per person approaches $11.95 as the number of people increases.

Good luck with the test! :)

The horizontal asymptote y = 0 represents that the cost per person approaches $0 as the number of people increases.

"An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance. In other words, Asymptote is a line that a curve approaches as it moves towards infinity."

"The curves visit these asymptotes but never overtake them. The method opted to find the horizontal asymptote changes involves comparing the degrees of the polynomials in the numerator and denominator of the function. If both the polynomials have the same degree, divide the coefficients of the largest degree terms."

From the equation, y = 11.95x + 25

And from the given graph it is clear that the horizontal asymptote y = 0 represents that the cost per person approaches $0 as the number of people increases.

Hence, A is the correct option.
