The given sequence is arithmetic progression AP. The common difference is found to be (-11).

Arithmetic Progression (AP) is a number sequence in which the difference between two numerical order is a constant value. Arithmetic Sequence is another name for it.

We would then come across some key terms in AP, that are denoted as:

Some formula use in AP are-

Now as per the given question;

The given sequence is  97,86,75,64, ...........

Let the first term is'a₁' = 97.

Let 'a₂' = 86 is the second term.

Let the third term is 'a₃' = 75.

Let the fourth term be 'a₄' = 64.

As we know, in the AP, the difference between two consecutive terms is equal and therefore is referred to as the common difference.

d = a₂ - a₁      

Substitute the values;

d = 86 - 97 = -11     ........(equation 1)

Now consider other pair;

d = a₃ - a₂    

d = 75 - 86 = -11      .......(equation 2)

Put the values;

Thus, both the two equation are equal. It means the common difference is same that is (d  = -11).

Therefore, the stated sequence is found to be in AP and the value of the common difference is found to be (d = -11).

The slope of line passing through points  (2,7) and (-3,11) is -4/5.

Slope of a Line

The slope of a line is defined as the increase divided by the run, or as the ratio of the rise to the run. It describes the slope of the line in the coordinate plane. Calculating the slope of a line and determining the slope between two different points are similar activities.

The following formula is used to determine slope:

The slope of the line between two points is given by y2 - y1 / x2 - x1.

Given points are -

(2,7) and (-3,11)

Slope of the line is -

= 11 - 7 / -3 -2

Equation: 6x + 8 = 80

Step-by-step explanation:

A triangle's angles add up to 180 degrees.  Knowing this, the angle represented by the "6x + 8" must equal 80 degrees since the other two angles add to 100 degrees.

Kristen will do both the exercises together, 6 days from now.

We are told that Kristen goes hiking every 3 days and swimming every 2 days.

The day she will do both the exercises together will be the day which is a multiple of the LCM of 2 and 3.

Now, since 2 and 3 are both prime numbers, their LCM (lowest common multiple) will simply be their product, which comes out to be-

LCM (2, 3) = 2 * 3

= 6

Thus, Kristen will do both the exercises on every 6th day.

Thus, if she went for both swimming and hiking today, she will do both the exercises together again 6 days from now.

The standard deviation decreases as the sample size increases.

The degree of data dispersion from the mean is measured by the standard deviation. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.

A region containing 68 percent of the total number of data points would be defined by one standard deviation, or one sigma, shown above or below the average value on that normal distribution curve. Ninety-five percent of the data would be covered by two sigmas above or below, whereas three sigmas would cover 99.7 percent.

The standard deviation is significant because it reveals the degree of dispersion of the values in a particular dataset. Every time we examine a dataset, we look for the following metrics: the dataset's geographic center.

Evaluating the expression 2a + b for a = 3 and b = -5 is equal to -1.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".

To evaluate an expression or an equation means to substitute a value to the variable and perform the arithmetic operations included.

Given the expression 2a + b, substitute the value of the variable a and the value of variable b.

2(3) + (-5)

Performing the arithmetic operations, we can have the value of the expression.

2(3) + (-5)

= 6 - 5

= 1

Hence, the expression 2a + b when a = 3 and b = -5 is equal to -1.

Piecewise function definition A piecewise function is a function that is defined by different formulas or functions for each given interval. Its also in the name: piece. The function is defined by pieces of functions for each part of the domain.

Using exponent properties we can get two equivalent expressions:

⁸√d^5

d^(5/8)

Here we need to use two properties, these are:

ⁿ√x = x^(1/n)

(x^n)^m = x^(n*m)

Now, if we use the first property, we can rewrite the expression as:

(d^1/8)^5 = ⁸√d^5

Which is an equivalent expression.

If we use the other property we can get:

(d^1/8)^5 = d^( (1/8)*5) = d^(5/8)

EN is a radius and the diameter is twice the radius. The diameter of the circle is 26 ft.

In geometry, a circle's diameter is any straight line segment that passes through the center of the circle and has endpoints on the circle. It is also referred to as the circle's longest chord. Both definitions apply to a sphere's diameter.

The diameter is twice the radius because the greatest distance between two points on a circle must be a line segment through the center of the circle.

Here, CF is a radius and the diameter is twice the radius.

Diameter of a circle = 2r

d = 2r

Where, r = 13

Diameter of a circle, d = 2r

Diameter of a circle = 2(13)

Diameter of a circle = 26

Therefore, the diameter of the circle is 26 ft.

Here, EN is a radius and the diameter is twice the radius.

Step-by-step explanation:

Okay so this is fun, let's lable the angle just under 72, but still on the right side B. now, side b is corresponding or equal to (2y+48). So you set them to equal 180 because it makes a straight line....

(2y+48) + 72 = 180

2y + 48 + 72 = 180

2y + 120 = 180

2y = 180 - 120

2y = 60

y = 60/2

y = 30

plug this back in and ...

2(30)+48 =

(60+48) =

108

No we'll use 108 + 72 to make sure that the y is correct and....

108 + 72 = 180 so.. CORRECT! :)

Answer:

There were 27 student tickets sold and 35 parent tickets sold.

Step-by-step explanation:

So first, we have to set up our equations!

s + p = 62 (s is the # of student tickets sold; p is the # of parent tickets sold;  62 is the total # of tickets sold)

1.75s + 3.75p = 178.50 (1.75s is the price for student tickets multiplied by the number of student tickets; 3.75p is the price for parent tickets multiplied by the number of parent tickets; 178.50 is the total amount of money)

Now! We are going to use elimination to solve for the variables, first for "s". To do this, we are going to multiply the first equation by -3.75!

     -3.75 (s + p = 62)

    -3.75s - 3.75 p = -232.50

+     1.75s + 3.75p = 178.50

        -2s = -54

          s = 27

Next! We have to solve for "p" by multiplying the first equation by -1.75!

-1.75 (s + p = 62)

    -1.75s - 1.75 p = -108.50

+     1.75s + 3.75p = 178.50

        2p = 70

          p = 35

Lastly, we know that there were 27 student tickets sold, and 35 parent tickets sold.

Answer:

it will cost $32.9 for a 47 mile taxi ride

Step-by-step explanation:

Since 36 miles takes 42 minutes and Costa $25.20 then 47 miles taxi rides will take

42/36 = per minute = 1.17

1.17 × 47 = 54.83

In order to find cost per minute = $25.2/42 = 0.6

then 54.83 × 0.6 = $32.898

∴it will cost $32.9 for a 47 mile taxi ride

Coordinates of dilated triangle A'B'C' is:

A' (10, 0), B'(0, 10), and C' (15, 0).

The scale of dilation can be calculated as:

k · ( 0, 0 ) = ( 0 , 0 )

k · ( 0 , 4 ) = ( 0 , 10 )

k · ( 6, 0 ) = ( 15, 0 )
