answer:

vertical

explanation:

vertical angles are angles opposite each other.

From the unique line postulate, we can draw unique line segment PM and as we are given that P is a point on the perpendicular bisector I of MN, the proof below has shown that using the definition of reflection, point P is the image of itself and point N is the image of point M

We are given :

Point P is a point on the perpendicular bisector, l, of MN.

Now, we want to prove that PM = PN

A Reflection in transformation can be defined as the transformation in which the figure is the mirror image of the other figure. This means that every point is a mirror reflection of itself .

With the aid of the definition of reflection, we can form the statement that point P is the image of itself , and point N is the image of M .

The line l which is the perpendicular bisector of MN acts as a Line of symmetry or axis of reflection.

Finally, when talking about transformations, it is common knowledge that reflections preserve length which means that the required proof PM = PN will hold true

Therefore, we will conclude that point N is the image of M .

The most appropriate choice for percentage will be given by- Percentage change in cost = 37.09 %

What is percentage?

A number or ratio which can be expressed as just a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a portion per hundred. Per 100 is what the word percent means. The letter "%" stands for it. As in 0.6%, 0.25%, etc., percentages can also be expressed as decimals or fractions. The grades earned in any subject have been calculated in terms of percentages in academics. Ram, for instance, scored 78% on his final exam. This rate is computed based on Ram's overall grade point average (GPA) across all subjects.

For example 2% means [tex]\frac{2}{100}[/tex].

Here,

Cost last year = 24500

Cost today = 14300

Change in cost = 24500 - 14300

                         = 10200

Percentage change in cost = [tex]\frac{10200}{24500} \times 100[/tex]

                                              = 37.09 %

The probability that the exactly 5 are white and 2 are red is126/1716 and,

the probability that at least 5 of the balls are white is 133/1716

Given that:-

Total number of balls in the urn = 13

Number of white balls = 6

Number of red balls = 7

Number of randomly selected balls = 7

We have to find the probability that the exactly 5 are white and 2 are red and the probability that at least 5 of the balls are white.

Probability that exactly 5 balls are white and  2 are red, P(x = 5) = [tex]\frac{^6C_5*^7C_2}{^{13}C_7}[/tex] = 126/1716 = 21/286

We know that,

Probability that atleast 5 balls are white = P(x = 5) + P(x = 6)

We know that,

P(x = 6) = [tex]\frac{^6C_6*^7C_1}{^{13}C_7}[/tex] = 7/1716

Hence,

Probability that atleast 5 balls are white = 126/1716 + 7/1716 = 133/1716.

Using a system of equations, a possible set of values for a, b and c such that it results in an integer number is given by:

a = 6, b = 3, c = 2.

A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the problem.

In the context of this problem, the variables are the given ones of:

a, b and c.

An integer number is a number that has no decimal part, hence the easiest way to solve this is making the sum of 1.

Attributing a = 6, we have that:

[tex]\frac{1}{6} + \frac{1}{b} + \frac{1}{c} = 1[/tex]

[tex]\frac{1}{b} + \frac{1}{c} = \frac{5}{6}[/tex]

This is possible with these two fractions:

[tex]\frac{1}{2} + \frac{1}{3} = \frac{3 + 2}{6} = \frac{5}{6}[/tex]

Hence the other possible values are given by:

The unit rate of muffins per cup of almonds that the baker is for every 9 muffins, he uses 1 cup of almonds.

The unit rate is the ratio of a variable against another variable.

The unit rate explains the quantity relationship between the number of muffins produced and the cups of almonds used by the baker.

For this situation, a cup of almonds can make 9 muffins.

The total number of muffins made = 36

The total number of cups of almonds used = 4

The ratio of muffins to cups of almonds = 36:4 or 9:1

The unit rate of muffins per cup = 9 (36/4)

Thus, the baker is producing 9 muffins per cup of almonds used.

Let's find the values of the variables so that the matrices are equal.

To find the values of the variables, divide the values of the result by the corresponding values of the main matrix.

We have:

• x = 4

• 7y = 21

Divide both sides by 7:

7y/7 = 21/7

y = 3

• z = 4

Therefore, we have:

• x = 4

• y = 3

• z = 4

ANSWER:

• x = 4

• y = 3

• z = 4

The statement that are true about the equations − 3 ⁢ x − 8 = 19  and − 3 ⁢ x − 2 = 25 is that he equations have the same solution because the second equation can be obtained by adding 6 to both sides of the first equation.

From the first equation, we were given,  − 3 ⁢ x − 8 = 19

then if we add 6 to the both sides of the equation then we will have

− 3 ⁢ x − 8 + 6 = 19 + 6

Then if we perform the simplification on this equation we have,

− 3 ⁢ x − 2 = 25

Answer:

[tex]y = \dfrac{2}{3}x + \dfrac{16}{3}}[/tex]

Step-by-step explanation:

The genera slope-intercept equation of a line is

y = mx + 8 where m is the slope and b the y-interecept

A perpendicular line will have a slope = -1/m ie the negative of reciprocal of the first line such that m x (-1/m ) = -1

The equation of the tangent line is

3x + 2y = 28.

1. Convert to slope-intercept form:

So slope = -3/2

Reciprocal of -3/2 = -2/3
Negative of reciprocal = +2/3

Slope of a perpendicular line should be -1/3 and the resultant equation of the line(the support arm) should be:

y = (2/3)x + b

To calculate b for the complete line equation plug in the point B(4, 8) and solve for B

y = 8 when x = 4

=> 8 = (2/3)(4) + b

Switch sides: (does not change any signs)
8/3 + b = 8

Subtract  8/3 on both sides
b =  8 - 8/3

b = 24/3 -  8/3

b = 16/3

So equation of the support arm is

[tex]\boxed{y = \dfrac{2}{3}x + \dfrac{16}{3}}[/tex]

The following characteristics apply to quadrilaterals, which are polygons.

To classify the quadrilateral calculate the length of its sides using the distance formula given as follows:

In the given quadrilateral RSTV,

RS = [tex]\sqrt{(2 - (-5))^{2} + (6 - 7)^{2} }[/tex] = [tex]\sqrt{50 }[/tex]

RV = [tex]\sqrt{(-4 - (-5))^{2} + (0- 7)^{2} }[/tex] = [tex]\sqrt{50}[/tex]

Complete question is;

A railroad crew can lay 7 miles of track each day. They need to lay 189 miles of track. The length, L (in miles), that is left to lay after d days is given by the following function. L(d) = 189 - 7d​

(How many days will it take the crew to lay all the track?)

(How many miles of track does the crew have left to lay after 18 days?)

Reason:

The angles shown must add to 180 degrees if we want the top and bottom lines to be parallel. These angles are same side interior angles.

(x+4)+(3x) = 180

4x+4 = 180

Answer:

[tex]y=4x[/tex]

Step-by-step explanation:

Slope-intercept form:

[tex]y=mx+b\\[/tex]

m is the slope

b is the y-intercept

Parallel lines have the same slope, therefore we know that our new line will have the slope m = 4.

Since the point is the origin (0,0) we also know that the y-intercept will be 0.

Using this information, write the equation of the line:

Using the normal distribution, it is found that:

a) The sampling distribution is approximately normal, with mean 45 and standard deviation 4.

b) The answer is not dependent on the sample size, as the underlying distribution is normal.

c) 0.0001 = 0.01% probability that the average is less than half an hour.

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

For this problem, the parameters are given as follows:

[tex]\mu = 45, \sigma = 12, n = 9[/tex]

Hence the standard error of the approximately normal sampling distribution of sample means of size 9 is:

s = 12/sqrt(9) = 12/3 = 4.

As stated in the problem, the underlying distribution is normal, hence this is not dependent on the sample size.

For item c, the probability is the p-value of Z when X = 30, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

Z = (30 - 45)/4

Z = -3.75

Z = -3.75 has a p-value of 0.0001.

Hence the probability is of 0.0001 = 0.01%.
