The measure of angle BAC is 20 degrees

The angle on a straight line is 180 degrees.

There are 9 equal sections on the straight line.

This means that the measure of each section is:

Each section = 180/9

Evaluate

Each section = 20

So, we have:

BAC = 20 degrees

Answer:

The equation of the line with gradient -1 that passes through the point (-3, 0) can be found using the point-slope form of a line. The point-slope form of a line is given by:

y - y1 = m (x - x1)

Where m is the gradient and (x1, y1) is a point on the line.

For this line, m = -1 and (x1, y1) = (-3, 0). Thus, the equation of the line is:

y - 0 = -1 (x - (-3))

y = -x + 3

Answer:

x + y + 3 = 0

Step-by-step explanation:

equation of line ( point slope format)

(y-y1) = m(x - x1)

they had given the point as (-3,0) on comparing with (x1, y1) and substituting the values in equation we get

y = -1(x +3)

final ans

x + y + 3 = 0

Answer:To conduct a hypothesis test using the p-value approach, the general steps are as follows:

State the null hypothesis (H₀) and the alternative hypothesis (H₁) based on the research question or claim.

Choose an appropriate statistical test based on the type of data and the research question.

Collect the necessary data and calculate the test statistic.

Determine the significance level (α) for the test, which will dictate the critical value or the region of rejection.

Calculate the p-value, which represents the probability of observing the obtained test statistic or more extreme values under the null hypothesis.

Compare the p-value to the significance level (α) to make a decision.

If the p-value is less than α, reject the null hypothesis in favor of the alternative hypothesis.

If the p-value is greater than or equal to α, fail to reject the null hypothesis.

Latitudes and longitudes help in locating a point by providing a reference system for navigation.

They are used to pinpoint a specific location on the earth’s surface by providing coordinates. These coordinates are measured in degrees and minutes and are written in the form of a pair of numbers. Latitudes are measured in degrees north or south of the equator and are referred to as the lines of latitude. Longitudes are measured in degrees east or west of the prime meridian and are referred to as the lines of longitude. By using the coordinates of a point, the location can be accurately determined. This is especially useful for navigation, as it enables people to determine their position and travel to a specific destination.

Answer:

HL

Step-by-step explanation:

The HL Therom only proves right triangles are congruent and since both triangles are right triangles, HL can work here.

The maximum value of z is 0, and the values of the decision variables are x1 = 0, x2 = 10, x3 = 0, x4 = 0.

maximize: z = c1x1 + c2x2 + ... + cnxn

subject to

a11x1 + a12x2 + ... + a1nxn ≤ b1

a21x1 + a22x2 + ... + a2nxn ≤ b2

am1x1 + am2x2 + ... + amnxn ≤ bmxi ≥ 0 for all i

In our case,

the given LP is:maximize: z = 36x1 + 30x2 - 3x3 - 4x

subject to:

x1 + x2 - x3 ≤ 5

6x1 + 5x2 - x4 ≤ 10

xi ≥ 0 for all i

We can rewrite the constraints as follows:

x1 + x2 - x3 + x5 = 5  (adding slack variable x5)

6x1 + 5x2 - x4 + x6 = 10  (adding slack variable x6)

Now, we introduce the non-negative variables x7, x8, x9, and x10 for the four decision variables:

x1 = x7

x2 = x8

x3 = x9

x4 = x10

The objective function becomes:

z = 36x7 + 30x8 - 3x9 - 4x10

Now we have the problem in standard form as:

maximize: z = 36x7 + 30x8 - 3x9 - 4x10

subject to:

x7 + x8 - x9 + x5 = 5

6x7 + 5x8 - x10 + x6 = 10

xi ≥ 0 for all i

To apply the simplex algorithm, we initialize the simplex tableau as follows:

  |  Cj   |   x5   |   x6   |   x7   |   x8   |   x9   |   x10  |    RHS  |

---------------------------------------------------------------------------

z |  0    |   0    |   0    |  36    |   30   |   -3   |   -4   |    0    |

---------------------------------------------------------------------------

x5|   0   |   1    |   0    |   1    |   1    |   -1   |   0    |    5    |

---------------------------------------------------------------------------

x6|   0   |   0    |   1    |   6    |   5    |   0    |   -1   |   10    |

---------------------------------------------------------------------------

Now, we can proceed with the simplex algorithm to find the optimal solution. I'll perform the iterations step by step:

Iteration 1:

1. Choose the most negative coefficient in the 'z' row, which is -4.

2. Choose the pivot column as 'x10' (corresponding to the most negative coefficient).

3. Calculate the ratios (RHS / pivot column coefficient) to find the pivot row. We select the row with the smallest non-negative ratio.

Ratios: 5/0 = undefined, 10/(-4) = -2.5

4. Pivot at the intersection of the pivot row and column. Divide the pivot row by the pivot element to make the pivot element 1.

5. Perform row operations to

make all other elements in the pivot column zero.

After performing these steps, we get the updated simplex tableau:

  |  Cj   |   x5   |   x6   |   x7   |   x8   |   x9   |   x10  |    RHS  |

---------------------------------------------------------------------------

z |  0    |   0    |  0.4   |  36    |   30   |   -3   |   0    |   12    |

---------------------------------------------------------------------------

x5|   0   |   1    |  -0.2  |   1    |   1    |   -1   |   0    |   5     |

---------------------------------------------------------------------------

x10|   0  |   0    |   0.2  |   1.2  |   1   |   0    |   1    |   2.5   |

---------------------------------------------------------------------------

Iteration 2:

1. Choose the most negative coefficient in the 'z' row, which is -3.

2. Choose the pivot column as 'x9' (corresponding to the most negative coefficient).

3. Calculate the ratios (RHS / pivot column coefficient) to find the pivot row. We select the row with the smallest non-negative ratio.

Ratios: 12/(-3) = -4, 5/(-0.2) = -25, 2.5/0.2 = 12.5

4. Pivot at the intersection of the pivot row and column. Divide the pivot row by the pivot element to make the pivot element 1.

5. Perform row operations to make all other elements in the pivot column zero.

After performing these steps, we get the updated simplex tableau:

  |  Cj   |   x5   |   x6   |   x7   |   x8   |   x9   |   x10  |    RHS  |

---------------------------------------------------------------------------

z |  0    |   0    |  0.8   |  34    |   30   |   0    |   4    |   0     |

---------------------------------------------------------------------------

x5|   0   |   1    |  -0.4  |   0.6  |   1    |   5   |   -2   |   10    |

---------------------------------------------------------------------------

x9|   0   |   0    |   1    |   6    |   5    |   0   |   -5   |   12.5  |

---------------------------------------------------------------------------

Iteration 3:

No negative coefficients in the 'z' row, so the optimal solution has been reached.The optimal solution is:

z = 0

x1 = x7 = 0

x2 = x8 = 10

x3 = x9 = 0

x4 = x10 = 0

x5 = 10

x6 = 0

Therefore, the maximum value of z is 0, and the values of the decision variables are x1 = 0, x2 = 10, x3 = 0, x4 = 0.

Step-by-step explanation:

to find the missing angle 180 degrees - 151 degrees

29° is the missing angle at the bottom ryt of the triangle.

all angles in triangle add upto 180°

so, 20x-3°+11x-1°+29°= 180°

31x=180°-25°

x= 1.6°

A polygon with three edges and three vertices is called a triangle.

x=1.6° is its value.

Based on the lengths of its sides, triangles can be categorized into one of three groups: Scalene. Isosceles. Equilateral.

The trigon, a 3-sided polygon, is sometimes (though not often) referred to as a triangle. Every triangle has three sides and three angles, some of which might be the same.

The triangle's angles are created by joining its three sides end to end at a single point. The sum of the three angles of the triangle is 180degrees.

To identify the omitted angle between 180 and 151 degrees

The triangle's bottom right corner lacks a 29° angle.

triangle's angles sum up to 180°

so, 20x-3°+11x-1°+29°= 180°

31x=180°-25°

The respective values in gigabytes (G) using the 2 to the power notation based on the 1G = \(2^3^0\) relationship are 10M = 0.01G, 100M = 0.1G, 110M = 0.11G

To convert values using the 2 to the power notation, we can use the relationship that 1G equals 2 to the power of 30 (\(2^3^0\)).

Here's how to express 10M, 100M, and 110M using this notation:

1. 10M:

To convert 10M (10 million) to the 2 to the power notation, we need to express it in terms of G (gigabytes).

Since 1G is equal to \(2^3^0\), we can calculate the value of 10M as follows:

  10M = (10/1000)G = 0.01G

Therefore, 10M is equivalent to 0.01G.

2. 100M:

Similarly, to express 100M (100 million) in the 2 to the power notation:

  100M = (100/1000)G = 0.1G

Therefore, 100M is equivalent to 0.1G.

3. 110M:

For 110M (110 million) in the 2 to the power notation:

  110M = (110/1000)G = 0.11G

Therefore, 110M is equivalent to 0.11G.

What is the system of equations?

A system of equations is a set of one or more equations that are to be solved simultaneously. The solution to a system of equations is the set of values for the variables that satisfy all the equations in the system.

In this case, the system of equations represents the amount that Brianna and Ahmed paid for 5 paintbrushes and 3 art canvases, and 10 paintbrushes and 6 art canvases, respectively. The system of equations is:

5x + 3y = 47 (Brianna's purchase)

10x + 6y = 94 (Ahmed's purchase)

To determine whether Brianna and Ahmed paid the same price for the items, we can compare the value of x and y that satisfy both equations. To do this, we can solve the system of equations using any method we prefer, such as elimination or substitution. Here, we'll use the method of substitution:

From the first equation, we can solve for y in terms of x:

5x + 3y = 47

3y = 47 - 5x

y = (47 - 5x)/3

Substituting this expression for y into the second equation, we get:

10x + 6y = 94

10x + 6((47 - 5x)/3) = 94

Simplifying, we get:

10x + 94 - 10x = 94

94 = 94

This equation is always true, regardless of the value of x.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

A restaurant catered an event for 25 people.

A child’s dinner cost $5 and an adult’s dinner cost $22.

The party cost $431.

let the number of children attendee be x and adult attendee be y.

So, x+ y = 25..............(1)

To determine a formula for the n-th term of an arithmetic sequence, we need to find the common difference (d) first.

The common difference is the constant value that is added or subtracted to each term to get to the next term.

In this case, we can find the common difference by subtracting the fourth term from the seventh term:

d = a₇ - a₄

d = 31 - 19

d = 12

Now that we have the common difference, we can use it to find the formula for the n-th term of the arithmetic sequence. The formula is given by:

aₙ = a₁ + (n - 1)d

In this formula, aₙ represents the n-th term, a₁ represents the first term, n represents the position of the term, and d represents the common difference.

Since we don't have the first term (a₁) given in the problem, we can find it by substituting the known values for a₄ and d:

a₄ = a₁ + (4 - 1)d

19 = a₁ + 3(12)

19 = a₁ + 36

a₁ = 19 - 36

a₁ = -17

Now we can substitute the values of a₁ and d into the formula to get the final formula for the n-th term:

aₙ = -17 + (n - 1)(12)

Therefore, the formula for the n-th term (aₙ) of the given arithmetic sequence is aₙ = -17 + 12(n - 1).

Ivory needs to make an additional 17 successful free throws without a miss to attain a success rate of 75%.

Let's start by finding Ivory's current free-throw success rate:

\(success rate = \frac{number of successful free throws}{total numbers of free throw} =\frac{7}{15}\)

We want to find the number of additional successful free throws Ivory must make to attain a success rate of $75%$, which can be written as:

\(success rate = \frac{numbers of successful free throws}{total numbers of free throws} = \frac{3}{4}\)

Let's call the number of additional successful free throws that Ivory needs to make "x". Then, we can write an equation based on the above expressions for success rate:

\(\frac{7 + x}{15 + x } =\frac{3}{4}\)

To solve for x, we can cross-multiply:

4( 7 + x) = 3 (15 + x)

28 + 4x = 45 + 3x

x= 17

Therefore, Ivory needs to make an additional 17 successful free throws without a miss to attain a success rate of 75%.

The 95% confidence interval for the students that were accepted is CI = 0.469 ± 0.022

We want the 95% confidence interval estimate for the proportion of County High School students accepted to a 4-year school out of high school, we can use the formula for the confidence interval for a balance.

The formula we need to use is: CI = p ± Z * √((p * (1 - p)) / n)

Where each variable is:

CI is the confidence interval

p is the sample proportion (accepted students / total students)

Z is the Z-score corresponding to the desired confidence level (95% confidence corresponds to a Z-score of 1.96)

n is the sample size

We know the values:

Sample size (n) = 2000

Number of accepted students (x) = 938

First, let's calculate the sample proportion (p):p = x / np = 938 / 2000p = 0.469

Now, let's calculate the confidence interval:CI = 0.469 ± 1.96 * √((0.469 * (1 - 0.469)) / 2000)CI

= 0.469 ± 1.96 * 0.01115863CI

= 0.469 ± 0.022

c. The 95% confidence interval is 0.469 ± 0.022, which can be written as an interval: [0.447, 0.491].

This means that you can be 95% confident that the proper proportion in the entire population is between 44.7% and 49.1%.
