Answer:

We need a non-included side of one triangle

Step-by-step explanation:

By means of the AAS postulate.

The Angle-Angle-Side postulate (AAS) tells us that if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.

Step-by-step explanation:

Answer:

0 = 3 is the final answer

Step-by-step explanation:

Step-by-step explanation:

Distance = √(x_2 - x_1)² + (y_2 - y_1)²

Distance = √[(-a) - a]² + (b - b)²

Distance = √[-2a]² + (0)²

Distance = √4a²

Step-by-step explanation:

Step 1: Define

18x - (-3x + 9)

Step 2: Simplify

There are two points that satisfy the system of equations:

(0.79, 0.37)

(-3.79, -12.37)

The system of equations is:

y = 3x - 3

y = -x^2

To determine which point from a specified set satisfies the system of equations, we need to find the values of x and y that satisfy both equations simultaneously.

Substituting y = 3x - 3 into the second equation, we get:

3x - 3 = -x^2

Rearranging this equation, we get:

x^2 + 3x - 3 = 0

Using the quadratic formula, we can solve for x:

x = (-3 ± sqrt(3^2 - 41(-3))) / (2*1) = (-3 ± sqrt(21)) / 2

Therefore, there are two possible values of x that satisfy the system of equations:

x = (-3 + sqrt(21)) / 2 ≈ 0.79

x = (-3 - sqrt(21)) / 2 ≈ -3.79

To find the corresponding values of y, we can substitute these values of x into either equation. For example, if we use y = 3x - 3, we get:

y ≈ 0.37 (when x ≈ 0.79)

y ≈ -12.37 (when x ≈ -3.79)

Therefore, there are two points that satisfy the system of equations:

(0.79, 0.37)

(-3.79, -12.37)

Answer: 0.5 gallon

Step-by-step explanation:

From the question, we are informed that Container a has a maximum capacity of 3 gallons. Container B has a maximum capcity of 14 quarts.

It should be noted that 4 quarts equals 1 gallon. Therefore, 14 quarts = 14/4 = 3.5 gallons

Container A = 3 gallons

Container B = 3.5 gallons

The difference will be:

= 3.5 gallons - 3 gallons

= 0.5 gallon

82 mm^2

Step-by-step explanation:

you would have to find the area for 2 squares. The first is 8 x 9, so the area of that would be 72. The second square is 5 x 2, which is ten. Add those together to get 82

the final answer is x= -7

The distribution of X₁ - 3X₂ is a normal distribution with mean μ₁ - 3μ₂ and variance s₁² + 9s²₂ - 6rhos₁s₂.

To find the distribution of X₁ - 3X₂, we need to find the mean and variance of this new variable.

The mean of X₁ - 3X₂ is:

E(X₁- 3X₂) = E(X₁) - 3E(X₂) = μ₁ - 3μ₂

The variance of X₁ - 3X₂ is:

Var(X₁ - 3X₂) = Var(X₁) + 9Var(X₂) - 6Cov(X₁,X₂)

Since X₁ and X₂ have a bivariate normal distribution with means μ₁ and μ₂, variances s₁ and s₂ and correlation rho, we know that:

Var(X₁) = s²₁

Var(X₂) = s²₂

Cov(X₁,X₂) = rhos₁ s₂

Substituting these values into the variance equation, we get:

Var(X₁ - 3X₂) = s₁² + 9s²₂ - 6rhos₁s₂.

For the actual number 3 and the predicted value 1.6 the residual  is equal to 1.4.

As given in the question,

The actual number is equal to 3

The predicted value is equal to 1.6

The residual is the difference between actual number and predicted value.

Formula for the residual is:

Residual = Actual number - Predicted value

Substitute the value of the actual number and the predicted value in the formula ,

⇒ Residual = 3 - 1.6

⇒ Residual = 1.4

Therefore, the residual for the given the actual number and the predicted value is given by 1.4.

If the markup for both swing sets is 20 1/4% . The school decides to buy the Adventurers swing set. The selling price of the swing set they are buying is:  $3,674.84.

Selling price can be defined as the amount a person intend to sell his/her product or the amount a buyer intend to buy a product.

Given data:

Adventurers  selling price = $3056

Thunder Ridge = 4,125

Markup 20 1/4% = 20.25 %

First  step is to find markup  

Markup = 20.25% × 3056

Markup =  $618.84

Now let find the selling price of the swing

Selling price = $3056 + $618.84

Selling price = $3,674.84

Therefore the selling price is the amount of $3,674.84.

You would plot -2.7

-2.3 - (-0.4) = -2.7

Starting from -2.3, you count 0.4 spaces to the left on the number line, leaving you with -2.7

The difference between the numbers -2.3 and -0.4 is -1.9 after using the number line.

It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.

It is given that:

As we can see in the number line:

-0.4 > -2.3

If we take the difference between these two numbers

From the number line:

= −2.3−(−0.4)

=-2.3 + 0.4

= -1.9

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

After using the arithmetic operation concept:

The difference between the numbers:

= −2.3−(−0.4)

=-2.3 + 0.4

= -1.9

Thus, the difference between the numbers -2.3 and -0.4 is -1.9 after using the number line.
