Answer:

The proportion of premises painted by Mario is [tex]\frac{3}{14}[/tex].

Step-by-step explanation:

The question is:

A local in Santa Bárbara was painted by 4 enterprising people who got together to start a dairy business; Juan, Pedro, Carlos and Mario; Juan painted 2/7 of the premises, Pedro painted 5/14 and Carlos painted 2/14; What fraction did Mario paint?

Solution:

Consider the proportion of the total premises painted is 1.

The four enterprising people who got together to start a dairy business are:

Juan (J), Pedro (P), Carlos (C) and Mario (M).

The proportion of premises painted by Juan is:

[tex]P(J)=\frac{2}{7}[/tex]

The proportion of premises painted by Pedro is:

[tex]P(P)=\frac{5}{14}[/tex]

The proportion of premises painted by Carlos is:

[tex]P(C)=\frac{2}{14}[/tex]

Compute the proportion of premises painted by Mario as follows:

P (M) = 1 - P (J) - P (P) - P (C)

        [tex]=1-\frac{2}{7}-\frac{5}{14}-\frac{2}{14}\\=\frac{14-4-5-2}{14}\\=\frac{3}{14}[/tex]

Thus, the proportion of premises painted by Mario is [tex]\frac{3}{14}[/tex].

Step-by-step explanation:

Simplifying

3p + -1 = 5(p + -1) + -2(7 + -2p)

-1 + 3p = 5(p + -1) + -2(7 + -2p)

-1 + 3p = 5(-1 + p) + -2(7 + -2p)

-1 + 3p = (-1 * 5 + p * 5) + -2(7 + -2p)

-1 + 3p = (-5 + 5p) + -2(7 + -2p)

-1 + 3p = -5 + 5p + (7 * -2 + -2p * -2)

-1 + 3p = -5 + 5p + (-14 + 4p)

-1 + 3p = -5 + -14 + 5p + 4p

 -5 + -14 = -19

-1 + 3p = -19 + 5p + 4p-1 + 3p = -19 + 9p

Solving

-1 + 3p = -19 + 9p

Solving for variable 'p'.

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

Add '-9p' to each side of the equation.

-1 + 3p + -9p = -19 + 9p + -9p

Combine like terms: 3p + -9p = -6p

-1 + -6p = -19 + 9p + -9p

Combine like terms: 9p + -9p = 0

-1 + -6p = -19 + 0

-1 + -6p = -19

Add '1' to each side of the equation.

-1 + 1 + -6p = -19 + 1

Combine like terms: -1 + 1 = 0

0 + -6p = -19 + 1

-6p = -19 + 1

Combine like terms: -19 + 1 = -18

-6p = -18

Divide each side by '-6'.

p = 3

Step-by-step explanation:

Given:

Edgardo has a drink cooler that holds 4 gallons of water.

He is filling the cooler with a 1−quart container.

Question asked:

How many times will he have to fill the quart container to fill the cooler?

Solution:

Capacity of container = 1 quart

As we know:

1 quart = 0.25 gallon

Edgardo has to fill drink cooler having capacity of 4 gallons.

0.25 gallon is filled by filling the container = 1 time

1 gallon is filled by filling the container = [tex]\frac{1}{0.25}[/tex] times

4 gallons is filled by filling the container = [tex]\frac{1}{0.25}\times4=16\ times[/tex]

Thus, he will have to fill the quart container 16 times to fill the cooler.

Answer:

84%

Step-by-step explanation:

Using the formula of z=(x-mean)/standard deviation. You get a z score of -1. Given the Empirival rule, 68% of all the values fall within 1 standard deviation. So the remaining 32% of values fall outside of this range. Since we have a negative 1, we only care about the lower half or 16%.

y= 1

x= -3

Step-by-step explanation:

4x-9y=-21

-4x-3y=9

solve the equation

4x=-21+9y

-4x-3y=9

substitute the value of 4x onto an equation

-1(-21+9y)-3y=9

multiply -1 to the numbers in parenthesis

-21+-9-3y=9

add -9 to 9 and put the negative on nine as a positive.

-21-3y=18

add -21 to 18 but since 21 is a negative the equation is subtraction.

-3y=-3

divide Both sides by -3

y=1

substitute the value of y into an equation

-4x-3•1=9

multiply 3 to 1

-4x-3=9

put -3 as a positive and add 3 to 9

-4x=12

divide both sides by -4

x= -3

(-3,1)

The solution for x and y in the given equations is x = 27 and y = 11.

Let's consider the second equation, -x + 3y = 6, and rewrite it in the form ax + by = c.

To get the equation in the required form, we'll rearrange the terms:

-x + 3y = 6

Add x to both sides:

3y = x + 6

Now, subtract 6 from both sides:

3y - 6 = x

This equation can be rewritten in the form ax + by = c by swapping sides:

x = 3y - 6

Now, let's substitute this expression for x into the first equation: 4x - 9y = 9.

4x - 9y = 9 becomes 4(3y - 6) - 9y = 9.

Simplify the equation: 12y - 24 - 9y = 9.

Combine like terms: 3y - 24 = 9.

Add 24 to both sides: 3y = 33.

Divide both sides by 3: y = 11.

Substitute y = 11 into x = 3y - 6: x = 3 × 11 - 6.

Calculate: x = 33 - 6 = 27.

Therefore, the solution for x and y in the given equations is x = 27 and y = 11.

Answer: divide it by the number of numbers you added up.

Step-by-step explanation:

For example, let's say you had to find the average of 1, 2, and 3. You add all the numbers up to get 6. Since you had to add 3 numbers together (1, 2, 3) to get 6, you divide 6 by 3 to get the mean/average, which in this case, is 2

To find the average or mean of a set of numbers, add up all the items and divide by how many numbers there are.

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words, it is the sum divided by the count.

The mean, or average, is calculated by adding up the scores and dividing the total by the number of scores.

Answer:

the answer is 2

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Using the Pythagorean theorem to check for a right angle, Stephanie's table measurements of 15 inches by 7.5 inches with a diagonal of 17 inches do not satisfy the theorem. Hence, the table is not perfectly rectangular.

To determine if Stephanie’s table is perfectly rectangular, we can apply the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. If the table is perfectly rectangular, the diagonal should be the hypotenuse of a right triangle formed by the length and width of the table.

The formula for the Pythagorean theorem is “a2 + b2 = c2”, where c is the hypotenuse, and a and b are the other two sides of the triangle. For Stephanie’s table: Length (“a”) = 15 inches, Width (“b”) = 7.5 inches, and Diagonal length (“c”) = 17 inches.

Let’s calculate it:

a^2 = 15^2 = 225
b^2 = 7.5^2 = 56.25
c^2 = 17^2 = 289

Add a2 and b2 together:

225 + 56.25 = 281.25

Since 281.25 is not equal to 289, the table is not perfectly rectangular because the measurements do not satisfy the Pythagorean theorem.

The table is not perfectly rectangular because the measured diagonal does not satisfy the Pythagorean Theorem with the given length and width.

To determine if Stephanie's table is perfectly rectangular, we can use the Pythagorean Theorem, which states that for a right-angled triangle, the square of the length of the hypotenuse (diagonal) is equal to the sum of the squares of the other two sides.

Let's denote:
Length (L) = 15 inches
Width (W) = 7.5 inches
Diagonal (D) = 17 inches

According to the Pythagorean Theorem:
D2 = L2 + W2

Now, substitute the given values:
172 = 152 + 7.52
289 = 225 + 56.25
289 = 281.25

Since 289 is not equal to 281.25, the table is not perfectly rectangular. Therefore, the measurements indicate that the table does not form a perfect rectangle.

Answer:

a. A dog's tail will wag differently in response to positive stimuli and to negative stimuli.

Step-by-step explanation:

A research hypothesis is a proposition that can be tested about the possible outcome of a study based on different stimuli.

A research hypothesis is a specific, clear, and testable proposition or predictive statement about the possible outcome of a scientific research study based on a particular property of a population, such as presumed differences between groups on a particular variable or relationships between variables.

Before a quantitative study takes place, it is important to state the research hypothesis because it is very important to the study.

There is usually an expectation or predicted outcome of the study because the research is determined by the hypothesis.

So it was already hypothesised that a dog would wag its tail in a preferred direction when it is faced with negative or positive stimuli. So the hypothesis was tested as different sets of dogs were placed in a cage and introduced to different stimuli.

From the observation of the researchers, all the dogs wagged their tails to the right when they saw a familiar face (positive stimuli) and wagged their tails to the left when they faced an aggressive dog (negative stimuli)

Because 4 is negative and would go left and 5 is positive so it would go up

Answer:

3500-750=2750

2750/300=9.1677

he gets 750 per month .. this means he is sure to get $750 every month.. so he already have $750 out of the 3500 so I subtract it... and 300 per car ,so I divide it , so that I can get the amount of car he needs to sell to get 3500

The inequality representing the minimum number of cars David needs to sell to earn at least $3,500 per month is x>=10, with x being the number of cars sold.

To determine the inequality for the number of sales David needs to make to earn a minimum of $3,500 per month, we consider his monthly income which includes a base salary and commission for cars sold. David earns a base salary of $750 plus a commission of $300 for each car he sells. Let's denote the number of cars David sells in a month as x.

The total monthly income David gets from commission by selling x cars is $300x. So, the total monthly income David earns is $750 (base salary) plus $300x (commission from sales), or $750 + $300x in total.

Since David needs to earn at least $3,500 monthly, his total monthly income must be greater than or equal to $3,500. We can represent this as the following inequality:

$750 + $300x >=$3,500

To find the minimum number of cars David needs to sell, we now solve for x:

Since David cannot sell a fraction of a car, he needs to sell at least 10 cars to meet his financial goal.

Therefore, the inequality for the number of sales David needs to make at least $3,500 per month is x >=10.

Option A) Center: (2,5) & Radius=7 is the correct one.

Step-by-step explanation:

The general form of the equation of the circle is given as :

⇒ (x-h)² + (y-k)² = r²

where,

Therefore, you need to compare the given equation with the general equation of the circle.

The given equation of circle is (x-2)² + (y-5)² = 49

From the given equation, it can be determined that

h = 2 and y = 5 and r² = 49

The center (h,k) of the circle is (2,5).

To find the radius r :

⇒ r² = 49

⇒ r = 7

The radius of the circle is 7.

∴ Option A) Center: (2,5) & Radius=7 is the correct one.

Hope this helps can I have brainliest

Final answer:

The discount on the tablet is $175.60.

Explanation:

To calculate the discount on the tablet which is 40% off the original price of $439, we need to use the formula:

Discount = Original Price × Discount Rate

Therefore:

Discount = $439 × 40%

First, convert 40% into a decimal, which is 0.40:

Discount = $439 × 0.40

Do the multiplication to find the discount:

Discount = $175.60

So, the discount is $175.60, and the tablet would then cost $439 - $175.60 = $263.40 after applying the discount.

Answer:

x = 1 and y = -8x

Step-by-step explanation:

Answer:

{y,x} = {-8,1}

Solve by Substitution :

// Solve equation [2] for the variable  y

 [2]    y = -8x

// Plug this in for variable  y  in equation [1]

  [1]    (-8x) - 6x = -14

  [1]     - 14x = -14

// Solve equation [1] for the variable  x

  [1]    14x = 14

  [1]    x = 1

// By now we know this much :

   y = -8x

   x = 1

// Use the  x  value to solve for  y

   y = -8(1) = -8

Solution :

{y,x} = {-8,1}
