What is the equation in point-slope form of a line that passes through the point (6,5) and has a slope of 1? Convert to slope-intercept

The correct answer is Option B. Parameters are defined as a group of numerical characteristics of a population.

Parameters are generally the numbers or values that represent the whole population's numerical characteristics. There is a difference between Statistics and Parameters.

Statistics is generally defined as the numerical characteristics of a sample. For example, a sample of standard mean or a sample of standard deviation is an example of statistics.

Parameters are the numerical representation of the characteristics of a population. For example, Population mean or Population standard deviation are examples of Parameters. These represent the data or the characteristics of the population in numerical.

Hence, the correct answer is Option B.

The required value of the number of sides ( n ) is 17.

What is polygon?

A closed, two-dimensional object composed of straight lines is called a polygon. In most cases, we can quickly determine the polygon's number of sides from its name.

Given, two of the exterior angles of an n-sided polygon are 25° & 26°

So, the sum of exterior angle = 25° + 26° = 51°

three of its interior angles are 161º each

So, each exterior angle = 180° - 161° = 19° .

sum of three exterior angles = 19*3 = 57° .

Then,

Remaining total angles = n - (2 + 3) = (n - 5).

And, the remaining interior angles are 159° each.

So, each exterior angle of the remaining angles = 180° - 159° = 21°.

sum of all (n -5) exterior angles remaining = 21(n - 5) = (21n - 105°) .

Now,

Sum of all exterior angles = 360°

or, 51° + 57° + (21n - 105°) = 360°

or, 21n + 108° - 105°  = 360°

or, 21n + 3° = 360°

or, 21n = 360° - 3°

or, 21n = 357°

or, n = 357/21 = 17

Hence, The required value of n is 17.

Answer:

50 mins

Step-by-step explanation:

80 percent=40 mins

100 percent=50 mins

The greatest percent error among the predictions is of:

2.23%.

The percent error of a measure is obtained by the division of the difference between the actual value and the estimated value by the actual value, and multiplied by 100%, hence the equation is:

Percent error = |Actual - Estimate|/Actual x 100%.

From the given dot plot, we have that the farthest measure from 22.4 seconds is of 22.9 seconds.

The difference between the actual time and the estimate time is of:

22.9 seconds - 22.4 seconds = 0.5 seconds.

Applying the presented division, the percent error is given as follows:

Percent error = 0.5/22.4 x 100% = 2.23%.

Answer:

The point at which these lines intersect is (-0.50, 1.07).  We can solve this in two ways:  mathematically or graphically.   Both are described.

Step-by-step explanation:

We have 2 equations, so we'll assume that the question is to find if they intersect, and if they do, where is the point of intersection.

Let's rewite the equations in slope-intercept format of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

  1)  9x + 7y = 3

   7y = -9x + 3

y = -(9/7)x + (3/7)  This line has a slope of -(9/7) and a y-intercept of +(3/7).

   2) x - 7y=-8

-7y = -x - 8

y = (1/7)x + (8/7)  This line has a slope of (1/7) and an intercept of (8/7)

The line have different slopes, so they will intersect.  We can find the intersection point by either graphing or by substitution.  We'll do both:

Substitution

We'll rearrange one equation in terms of x and then use that value of x in the second equation.  Thuis has the effect of eliminating one of the variables (x or y) so that we can solve for the remaining value of x or y,

We've rearranged both equations so that they have y equal to an expression involving x.  If the lines intersect, we know that y in both equations will be the same at that point, so set the equations equal to each other and solve for x:

y = -(9/7)x + (3/7)

y = (1/7)x + (8/7)

Therefore:   -(9/7)x + (3/7) = (1/7)x + (8/7)

-(9/7)x -(1/7)x = + (8/7) - (3/7)

-(10/7)x = +(5/7)

x = (5/7)*(-7/10)

x = (-35/70)

x = -0.50

Now we can use this value of x to find y:

9x + 7y = 3

9(-0.50) + 7y = 3

-4.5 + 7y = 3

7y = 3+4.5

y = (7.5/7)

y = 1.07

The point at which these lines intersect is (-0.50, 1.07)

Graphing:

We can also graph the two equations and then look for the intersection.  See the attached graph.  The lines intersect at (-0.50, 1.07)

The mathematical approach has more certainty, since it does not require interpreting the intersection point on a graph.  Use the graphing approach to check the conclusion from the substitution approach.

The domain of the function d(t)=1/2t+6 is (-∞, ∞) and the range of the function is (-∞, ∞).

Similar to how we input different numbers into functions, we also receive new numbers as the outcome. The two main characteristics of functions are domain and range.

A function's domain and range are its constituent parts. A function's range is its potential output, whereas its domain is the set of all possible input values. Range, Domain, and Function. A is the domain and B is the co-domain if a function f: A  → B exists that maps every element of A to an element in B.

In order to determine the expected value of a player's winnings on each roll, we would list all of the outcomes that are associated with rolling a fair six-sided die.

By rolling a fair six-sided die, we would obtain the following outcomes:

Outcomes = 1, 2, 3, 4, 5, and 6.

Generally speaking, there are only two (2) numbers that are multiples of three (3) in a fair six-sided die and these include the following:

Multiples of three (3) = 3 and 6

When a player rolls a three (3), the player's possible winning is giving by:

Player's winning = 3 × 20 = $60

When a player rolls a three (3), the player's possible winning is giving by:

Player's winning = 6 × 20 = $120

Total winnings = $60 + $120

The length of AD in the parallelogram is 143 cm.

A parallelogram is a quadrilateral with opposite sides parallel to each other. The opposite angles of a parallelogram are equal. Two adjacent or consecutive angles of a parallelogram are supplementary.

Hence,

2x + 72 + 2x - 20 = 180

4x + 52 = 180

4x = 180 - 52

4x = 128

divide both sides by 4

4x / 4 = 128 / 4

x = 32

Therefore,

∠A = 2(32) + 72 = 64 + 72 = 136 degrees

z = 136°

Therefore,

AC = BC = BD = AD

AC = z + 7

AC = 136 + 7

Equation of the line which passes through the given points (-p ,-q) and

(p, q) is given by:

(x₁ , y₁) = (-p ,-q)

The probability that the married couple will have adjacent desks is 0.2857and the probability that the married couple will have non-adjacent desks is 0.7143.

Probability is synonymous with potential. It is a branch of mathematics that studies the occurrence of a random event. The number ranges from 0 to 1. In mathematics, probability has been introduced to predict how likely events are to occur.

Given that

Of 7 new employees, 2 employees are married to each other; these 7 employees are to be assigned 7 desks that are lined up in a row.

If the assignment of the employees to the desks is made randomly, we have to find the probability that the married couple will have adjacent desks and will have non-adjacent desks.

Now, the event that the couple has non-adjacent desks is the complement of the event that they have adjacent desks.

Now, first, let us determine in how many ways can the couple have adjacent desks.

Let us consider the married couple as a single entity, that always stays together.

Then, in total, there are 6 entities; 5 non-related employees and 1 married couple.

Now, these 6 can be arranged among themselves in 6! number of ways.

The married couple can have adjacent desks in 2! ways.

So, the favorable number of cases, in which the couple has adjacent desks, is 6!*2!.

Again, 7 employees can be assigned desks in 7! number of possible ways.

That is, the number of all possible cases is 7!.

This means that

P(The couple has adjacent desks)

=6!*2!/7!

=0.2857.

Now,

P(The couple will have non-adjacent desks)

=1-P(The couple will have adjacent desks)

=1-0.2857

=0.7143

Therefore the probability that the married couple will have adjacent desks is 0.2857and the probability that the married couple will have non-adjacent desks is 0.7143.

The mode is the number that occurs in a set the most. You can remember this as the word "most" and "mode" sounding similar.

A sample to have a standard deviation of zero means the score has no variability.

When the score has no variability it points towards the standard deviation being zero, This is the case where all the scores in the sample have the exact same value. This means there is no spread in the data set at all. The data set is combined in a single clumped value. Since there is only one value it would be the mean of the data set.
