Find parallelogram ABCD attached

Answer:

x = 3

Step-by-step explanation:

In parallelograms, the diagonals typically divide each other into 2 equal parts.

This means that from the attached parallelogram, we can say that;

4x - 6 = 2x or 6x - 15 = x

Thus;

4x - 2x = 6

2x = 6

x = 6/2

x = 3

Let's confirm with the second equation;

6x - x = 15

5x = 15

x = 15/5

x = 3

Answer:

Is 03.841

Step-by-step explanation:

To find the critical value needed to test the claim that the sentence is independent of the plea, we need to perform a chi-square test of independence. The critical value is based on the significance level (α) and the degrees of freedom.

In this case, the given significance level is 0.05. Since the table represents a 2x2 contingency table (two categories for plea and two categories for sentence), the degrees of freedom (df) can be calculated as (number of rows - 1) * (number of columns - 1) = (2 - 1) * (2 - 1) = 1.

To find the critical value at a significance level of 0.05 with 1 degree of freedom, we consult a chi-square distribution table or use statistical software.

The critical value for a chi-square test with 1 degree of freedom and a significance level of 0.05 is approximately 3.841.

Therefore, the correct answer is 03.841.

How do triangles work?

The three vertices of a triangle make it a three-sided polygon. The angles of the triangle are formed by the connection of the three sides end to end at a single point.

                        The triangle's three angles add up to a total of 180 degrees. Three sides, three angles, and three vertices make up the closed, two-dimensional shape of a triangle. A triangle is a type of polygon.

The area of this triangle is 12 cm².

The area of this triangle = 1/2 * b * h

                          12 = 1/2 * 6 * h

                          h = 4 cm²

[~S & (R V S)] ≡ (Q ⊃ S) is true when A = T, S = F, R = F, and Q = T by substituting the propositional variables.

A truth table is a table used to determine the truth values of a compound proposition, which is a logical statement made up of simpler propositions using logical operators such as "and" (represented by "&"), "or" (represented by "V"), "not" (represented by "~"), conditional (represented by "⊃"), and biconditional (represented by "≡").

Let's substitute the given truth values for the propositional variables in the given statement:

[~F & (F V F)] ≡ (T ⊃ F)

Using the truth table for conjunction (represented by "&") and disjunction (represented by "V"), we can simplify the left-hand side of the equivalence:

[T & F] ≡ (T ⊃ F)

Using the truth table for conditional (represented by "⊃"), we can simplify the right-hand side of the equivalence:

F ≡ F

Since both sides of the equivalence have the same truth value, the statement is true.

Therefore, [~S & (R V S)] ≡ (Q ⊃ S) is true when A = T, S = F, R = F, and Q = T.

Size of the house should be 2900 ft².

Correct option is B.

We have,

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

Given,

Equation for the line that expresses price of house

y = 0.06x + 60.5

where y is the price in thousand dollars, x is area in square feet.

Price of the house = $235000

⇒ y = 235

Then,

235 = 0.06x + 60.5

0.06x = $235 - 60.5

0.06x = 174.5

x = 174.5/0.06

x = 2908.33 ≈ 2900

Hence, 2900 ft² should be the size of the house.

The cost of each pound of grass seed is $6.

A graph of the solution for the cost of each pound of grass seed is shown below.

In order to determine the cost of each pound of grass seed, we would assign a variable to the cost of each pound of grass seed and then translate the word problem into an algebraic linear equation.

Let the variable x represent the cost of each pound of grass seed.

Since Lori bought 3.6 pounds of grass seed and she was charged $22.90, including a tax of $1.30, an algebraic linear equation that best represent this situation is given by;

3.6x + 1.30 = 22.90

3.6x = 22.90 - 1.30

3.6x = 21.60

x = 21.60/3.6

x = $6.

In conclusion, we would sue an online graphing calculator to plot the solution for the cost of each pound of grass seed as shown in the image attached below.

Answer:

g(11) = 101

Step-by-step explanation:

g(r) = -20 + 11r

So in g(11), we just need to replace 'r' with '11'

g(11) = -20 + 11 (11)

--> g(11) = -20 + 121 = 101

--> g(11) = 101

Step-by-step explanation:

1/3 = 2/6 so 2/6 + 1/6 = 3/6

3/6 = 1/2

Answer:

1/2

Step-by-step explanation:

Since we're dealing with fractions, the total fraction is 1

Mortgage =1/3

Food =1/6

Fraction of income left=x

So we equate everything above to 1

\( \frac{1}{3} + \frac{1}{6} + x = 1\)

\( \frac{1}{3} + \frac{1}{6} + x = 1 \\ lcm = 6 \\ multiply \: each \: term \: by \: 6 \\ 6 \times \frac{1}{3} + 6 \times \frac{1}{6} + 6(x) = 6(1) \)

\( = > 2(1) + 1(1) + 6x = 6 \\ 2 + 1 + 6x = 6 \\ 3 + 6x = 6\)

\(6x = 6 - 3 \\ 6x = 3 \\ x = \frac{3}{6} = \frac{1}{2} \)

a) The linear model is Heart weight = 0.66 + 5.26 Body weight

b) The intercept of the model is 0.66

c) The slope of the model is 5.26

d) The correlation coefficient between body weight and heart weight is 0.843, which indicates a strong positive relationship between the two variables.

Regression analysis is a statistical method used to investigate the relationship between two or more variables. In this case, we are interested in predicting the heart weight of domestic cats based on their body weight. The regression output below presents the results of a linear regression analysis.

(a) The linear model is:

Heart weight (in g) = 0.66 + 5.26 Body weight (in kg)

This means that for every 1 kg increase in body weight, the heart weight of cats is expected to increase by 5.26 g. The intercept of 0.66 represents the predicted heart weight when the body weight is 0 kg. However, since it is not possible for a cat to have a body weight of 0 kg, the intercept is not very meaningful in this context.

(b) The intercept is the predicted value of the response variable when the predictor variable (body weight) is zero. In this case, the intercept of 0.66 is not very meaningful because it is not possible for a cat to have a body weight of zero. Therefore, we should focus on the slope of the regression line.

(c) The slope of the regression line represents the rate of change in the response variable for a one-unit increase in the predictor variable. In this case, the slope of 5.26 means that for every 1 kg increase in body weight, the heart weight of cats is expected to increase by 5.26 g. Therefore, the slope is a more useful measure for predicting heart weight based on body weight.

(d) To calculate the correlation coefficient, we can use the formula:

r = (nΣXY - ΣXΣY) / √[(nΣX² - (ΣX)²)(nΣY² - (ΣY)²)]

where n is the sample size, X and Y are the variables, and Σ represents the sum of the values. Using the data provided in the regression output, we can calculate the correlation coefficient as:

r = (144867.25 - 1206.7867.76) / √[(1442027.22 - 1206.78²)(144384.91 - 67.76²)]

In which:

In this problem, the number of ounces of water left in the bown after x hours is given by:

y = -0.5x + 4.

Variable x is the input, hence, it represents the number of hours since the bowl was filled.

More can be learned about linear functions at https://brainly.com/question/24808124

Answer:

Part A: The number of ounces of water left in the bowl depends on the number of hours since the bowl was filled. So the number of ounces is the dependent quantity. The y-variable represents the dependent quantity. So, the y-variable represents the ounces of water left in the bowl.

Part B: The number of hours since the bowl was filled is the independent quantity. The x-variable represents an independent quantity. So, the x-variable represents the number of hours since the bowl was filled.

Part C: The value 4 is the initial value of the function. It represents the ounces of water in the bowl immediately after the bowl was filled and before the cat drank any water from the bowl.

Part D: The value -1/2 is the function’s rate of change. It represents the change in ounces of water in the bowl with every hour.

Step-by-step explanation:

I took the Edmentum test.

The bearing from the phone to the transmitter is approximately 31 degrees to the east of the north direction.

To determine the bearing from the phone to the transmitter, we can use trigonometry.

The bearing is typically measured clockwise from the north direction.

Given that the transmitter is 13 km west and 21 km south of the phone, we can form a right triangle with the phone as the vertex angle.

The side opposite to the vertex angle represents the north-south direction, and the side adjacent to the vertex angle represents the east-west direction.

Using the tangent function, we can calculate the angle:

tangent(angle) = (opposite side) / (adjacent side)

tangent(angle) = 21 km / 13 km

Taking the inverse tangent (arctan) of both sides, we find:

angle = arctan(21 km / 13 km)

Evaluating this using a calculator, we find the angle to be approximately 58.57 degrees.

However, since the bearing is measured clockwise from the north, we need to subtract this angle from 90 degrees (which represents the north direction) to obtain the bearing:

bearing = 90 degrees - 58.57 degrees

Calculating this, we find the bearing to be approximately 31.43 degrees.
