Step-by-step explanation:

Rotate the triangle, so that x1 line becomes base. So, the measure of base will be y2-y1. To find the perpendicular height from the base, subtract x1 from x3. Then put the results in area of triangle formula.

There are 43,949,268 different 19-member subcommittees that may be chosen from among the 29 Senators on the Appropriations Committee.

To find the number of different 19-member subcommittees that may be chosen from among the 29 Senators on the Appropriations Committee, we can use the combination formula:

C(n, r) = n! / (r! * (n-r)!)

where n is the total number of members (29 in this case) and r is the number of members in the subcommittee (19 in this case).

Substituting the values, we get:

C(29, 19) = 29! / (19! * (29-19)!)

Simplifying by cancelling out common factors in the numerator and denominator, we get:

C(29, 19) = (29 * 28 * 27 * ... * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (19 * 18 * 17 * ... * 3 * 2 * 1 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1)

Many terms in the numerator and the denominator cancel out, leaving:

C(29, 19) = (29 * 28 * 27 * ... * 11) / (19 * 18 * 17 * ... * 3 * 2 * 1)

Calculating each factor, we get:

C(29, 19) = 43,949,268

Given quadratic equation has same solution set as -x=x²+12x+36 i.e. C.

A second-degree algebraic equation in x is a quadratic equation. Ax2 + bx + c = 0 is the quadratic equation in its standard form, with a and b acting as coefficients, x acting as the variable, and c acting as the constant term.

The coefficient of x2 must not be zero (a 0) for an equation to qualify as a quadratic equation. The x2 term comes first, followed by the x term, and finally the constant term when stating a quadratic equation in standard form. Instead of being written as fractions or decimals, the numerical values a, b, and c are frequently expressed as integral values.

The system equation that models the amount of calories from fats (f) and proteins (p) that the individual can consume to reach 1,800 calories is: f + p = 1,200. The equation that relates calories from protein (p) to calories from fat (f) based on the prescribed diet is: p = 3f. Solving the system of equations, we find that the individual should consume 300 calories from fats and 900 calories from proteins.

To find the equation that models the amount of calories from fats and proteins that the individual can consume in order to reach 1,800 calories, we consider that 600 calories will come from carbohydrates. Since the total goal is 1,800 calories, the remaining calories from fats and proteins should add up to 1,800 - 600 = 1,200 calories. Therefore, the equation is f + p = 1,200.

Based on the prescribed diet, the individual is required to consume calories from protein that are three times the calories from fat. This relationship can be expressed as p = 3f, where p represents the calories from protein and f represents the calories from fat.

To solve the system of equations, we substitute the value of p from the second equation into the first equation: f + 3f = 1,200. Combining like terms, we get 4f = 1,200, and dividing both sides by 4 yields f = 300. Substituting this value back into the second equation, we find p = 3(300) = 900.

Therefore, the individual should consume 300 calories from fats and 900 calories from proteins to meet the diet requirements and achieve a total of 1,800 calories.

Answer:

3 loaves

Step-by-step explanation:

See attachment for complete question.

Represent Loaves with L and Flour with F

Since L is proportional to F, the relationship can be defined as:

L = kF

Where k represent the constant of proportionality

When L = 4, F = 20

Substitute these values in the above formula.

4 = k * 20

Divide both sides by 20

4/20 = k

⅕ = k

k = ⅕

To solve for 15 cups of Flour, we have:

F = 15

Substitute 15 for F and ⅕ for k in L = kF

L = ⅕ * 15

L = 3

Hence, 3 loaves will be baked using 15 cups of flour

If the explanatory variables explained more than 20% of the variation in the response variables, it would mean that the coefficient of determination is above 0.2.

The coefficient of determination, also known as R-squared, is a statistical measure that represents the proportion of the variation in the dependent variable that is explained by the independent variables in a regression model. It ranges from 0 to 1, with 1 indicating that all the variation in the dependent variable is explained by the independent variables and 0 indicating that none of the variation is explained.

Therefore, if the explanatory variables explain more than 20% of the variation in the response variables, it means that the coefficient of determination is greater than 0.2. This is a good indicator that the regression model is a good fit for the data and that the independent variables are significant predictors of the dependent variable.

It is important to note that the question does not mention anything about there being two response variables or two explanatory variables. Therefore, we cannot conclude anything about the number of variables based on the given information.

However, we can conclude that the explanatory variables are significant in explaining the variation in the response variable.

The work done by the force is approximately 1.9 Joules.

The force experienced by an object moving along the parametrized curve r(t) = t, t², t³ with 0 ≤ t ≤ 1

when the force is given by f = 2x²y, -xz, 2z can be computed using the equation,W = ∫F.dr,where F is the force vector and dr is the displacement vector of the object.

Therefore, the work done by the force is given byW = ∫F.dr = ∫(2x²y, -xz, 2z).(dx, dy, dz)

Here, we need to express the given parametric equation of the curve in terms of x, y, and z.t = x, t² = y, t³ = z.

Then, dx = dt, dy = 2tdt, dz = 3t²dt.

Substituting these values, we haveW = ∫(2x²y, -xz, 2z).(dx, dy, dz)= ∫(2x²t², -x.t³, 2t³).(dt, 2tdt, 3t²dt)= ∫(2t².x² + 6t⁵)dt = [2/3.t³.x² + 1/2.t⁶]₁₀= (2/3.1³.x² + 1/2.1⁶) - (2/3.0³.x² + 1/2.0⁶)= 2/3.x² + 1/2.≈ 1.9J

A planted seed has a 85% chance of growing into a healthy plant. The probability that exactly 4 out of 11 seeds don't grow is approximately 0.1302.

To calculate this probability, we can use the binomial distribution formula. In this case, each seed has a 15% chance of not growing (1 - 0.85). We want to find the probability that exactly 4 seeds out of 11 don't grow.

Using the binomial distribution formula, the probability can be calculated as:

\(P(X = 4) = (^{11}C_4) * (0.15)^4 * (0.85)^7\)

Where (\(^{11}C_4\)) represents the number of ways to choose 4 seeds out of 11, \((0.15)^4\)represents the probability of 4 seeds not growing, and\((0.85)^7\) represents the probability of the remaining 7 seeds growing.

Evaluating the formula, we find:

\(P(X = 4) = (11! / (4! * 7!)) \times(0.15)^4 \times (0.85)^7 \approx 0.1302\)

Therefore, the probability that exactly 4 out of 11 seeds don't grow is approximately 0.1302, or 13.02%.

Probability that a student who passed the test did not  complete the homework = 0.07

Step-by-step explanation:

Given:

Total number of students = 28

Number of students who passed the test = 18

Number of students who completed  the assignment = 23

Number of students who passed the test and also completed the  assignment = 16

To find: probability that a student who passed the test did not  complete the homework

Solution:

Probability refers to chances of occurrence of some event.

Probability = number of favorable outcomes/total number of outcomes

Let A denotes the event that students passed the test and B denotes the event that students completed  the assignment

P(A only) = \(P(A)-P(A\cap B)\)

Here,

\(P(A)=\frac{18}{28}\,,\,P(A\cap B)=\frac{16}{28}\)

So,

\(P(A\,\,only)=\frac{18}{28}-\frac{16}{28}=\frac{2}{28}=\frac{1}{14}=0.07\)

(1/5)x - 2 + 2 = 4 + 2

On simplifying:

(1/5)x = 6

Step 2: Multiply both sides of the equation by 5 to get rid of the fraction (1/5):

5 * (1/5)x = 5 * 6

y = 5

Step-by-step explanation:

Since the lines are parallel, same side interior angles are supplementary.

That allows us to solve for x.

7x + 17 + 5x - 5 = 180

12x = 168

x = 14

The angles 23yand 5x - 5 are supplementary, so the sum of the measures equals 180°.

23y + 5x - 5 = 180

We already know that x = 14.

23y + 5(14) - 5 = 180

23y = 115

y = 5
