Step-by-step explanation:

To do the following I first listed the numbers from least to greatest

mean: (also known as average) is 7 just add all the numbers together and divide by the amount of numbers there are which is 77/11

median: 5 it's the middle number (5, 5, 6)

mode: 2 the number that appears the most

range: 16 difference between the highest value and the lowest (18-2)

quartile 1: 2 median of the lower half

Answer:

Step-by-step explanation:

Answer:

(1, 1 )

Step-by-step explanation:

Given the 2 equations

2x - 4y = - 2 → (1)

3x + y = 4 → (2)

Multiplying (2) by 4 and adding the result to (1) will eliminate the y- term

12x + 4y = 16 → (3)

Add (1) and (3) term by term to eliminate y

14x + 0 = 14

14x = 14 ( divide both sides by 14 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (2)

3(1) + y = 4

3 + y = 4 ( subtract 3 from both sides )

y = 1

solution is (1, 1 )

2 ft

Step-by-step explanation:

The height from which the beach ball was thrown happens when t = 0. So setting t = 0 to get y, we get

y = [-16(0) - 2](0 - 1)

= (-2)(-1)

= 2 ft

Therefore, the ball was thrown from a height of 2 ft.

Answer: y=5/3x-4

Step-by-step explanation:

Hi, you could find the slope with any 2 points on the line. For accuracy, I will choose the points (6, 6) and (0, -4), meaning when x =6, y=6, and when x=0, y=-4. Then you can set up an equation. Because the line on this graph is linear (meaning straight), the form of the equation would be y=ax+b. (If it was a parabola, it would be y=ax^2+bx+c).

y=mx+b (Or some people prefer y=ax+b, but the same thing).

Now, plug in the x and y values, getting:

6 = 6m+b and -4=0*m+b

When you simplify, you will get that b is -4, and then m is 5/3

So the equation is y=5/3x-4

You can plug the numbers of x and y in to check your answer.

Hope this helps!

Answer:

118419,54

Step-by-step explanation:

Primero, convierta R como porcentaje en r como decimal

r = R / 100

r = 16/100

r = tasa de 0,16 por año,

Luego resuelve la ecuación para A

A = P (1 + r / n) ^ nt

A = Cantidad =?

P = Principal = 80000

R = 16%

n = Compuesto trimestralmente = 4

t = tiempo en años

= 2 años y 6 meses

12 meses = 1 año

6 meses = x

x = 6/12 = 0,5

t = 2.5 años

A = 80000,00 (1 + 0,16 / 4) (4) ^ (2,5)

A = 80000,00 (1 + 0,04)^ (10)

A = $ 118419,54

Answer:

1) x-5=15

2) both 8w=64 & 48÷w=6

3) 28 square units

Answer:

Step-by-step explanation:

Answer:

x=2, y = -4.

or as an ordered pair it is (2, -4).

Step-by-step explanation:

-x + 6y = -26

x + 5y =  -18      Add these 2 equations to eliminate x:

0 + 11y = -44

y = -44/11 = -4.

Now substitute y = -4 in the first equation:

-x + 6(-4) = -26

-x - 24 = -26

-x = -26 + 24 = -2

x = 2.

Check the result by substituting in equation 2:

x + 5y = 2 + 5(-4) = 2 - 20 = -18  - checks out.

Step-by-step explanation:

What is an equation? In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value. The most basic and common algebraic equations in math consist of one or more variables.

Answer:

276 Guests

Step-by-step explanation:

Calculation to determine how many guest were at the wedding

Guests that choose beef =1/3

Guests that choose chicken= 5/12

Guests that choose vegetarian=69

Now let calculate the how many guest were at the wedding

Let x represent the numbers of guest that were present at the wedding

Hence,

x/3 + 5x/12 + 69 = x

9x/12 + 69 = x

12x/12 - 9x/12 = 69

3x/12 = 69

x/4 = 69

x=69*4

x = 276 guests

Therefore the numbers of guests that were at the wedding is 276

Answer: 276

Step-by-step explanation: Let “x” be the number of guest.

1/3 x +5/12x + 69 = x Simplifying and solving for x … where x = 276

1/3(276) + 5/12(276) + 69 = 276

92 + 115 + 69 = 276

Probability that both Rebecka and Aaron select poodles is  4/81

It is a branch of mathematics that deals with the occurrence of a random event.

Given,

A pet store has 9 puppies.

includes 2 poodles, 5 terriers, and 2 retrievers.

Rebecka selects one puppy at random.

The probability of selection one pet from store is 1/9

After Rebecka selects one puppy at random pet store replaces the puppy with a puppy of the same breede. Now store has same number of pets.

Aaron chooses a puppy at random.

The probability of Aaron selecting a pet is 1/9.

As they both selects a poodle,

Rebecka : Probability of selection one poodle from store is 2/9

Aaron: Probability of selection one poodle from store is 2/9

The probability that both Rebecka and Aaron select poodles is 2/9 × 2/9 = 4/81

Hence probability that both Rebecka and Aaron select poodles is  4/81
