The total amount that the band earns when the concert  sells out is $18566.50

Given,

Number of seats in The Playhouse Concert Hall = 523

The cost for one ticket charged by The Pink Ladies rock band who holds a concert = $35.50

We have to find the total amount that the band earns when the concert  sells out;

Total amount = Number of seats x Cost for one ticket

Total amount = 523 x 35.50

Total amount that the band earn = $18566.5

The correct algebraic form is b. k/-9 + 7 = 17

There are four components in division namely divisor, dividend, quotient and remainder. The significance and meaning of each is evident from their name. The dividend is the number that is being divided. And the number which is used to divide the dividend is divisor. The result of dividing the dividend by divisor is termed as quotient. Remainder is the left over amount.

So, multiplying the divisor and quotient and adding the product with remainder will give us the desired algebraic expression. Seven is remainder. The quotient of k and negative nine implies k is dividend and negative nine is divisor. So, algebraic expression -> k/-9 + 7 = 17

A line that intersects two or more lines at a distinct point is known as a transversal line.

A transversal is a line in geometry that connects two lines in the same plane at two different places. When determining whether two or more other lines in the Euclidean plane are parallel, transversals are important. Consecutive interior angles, consecutive exterior angles, corresponding angles, and alternate angles are only a few examples of the several pairings of angles that can be formed when a transversal intersects two lines. Euclid’s parallel postulate states that if two lines are parallel, then comparable interior angles are equal, alternate interior angles are equal, and successive interior angles are supplementary.

If we compute a 92% confidence interval in  excel command the critical value will be 1.750686.

Level of confidence c = 0.92

level of significance α = 1 - c = 0.08

A 92% confidence interval has goes from  8/2 = 4% to 100%–(8/2)% = 96%

Leaving 92% in the middle (96%–4%) = 92 %

So look up z-score for 96% or p =0.96

The two closest value in a z-table are

P(z< 1.75) = 0.95994

P(z< 1.76) = 0.96080

Based on this online table

( https://www.math.arizona.edu/~rsims/ma464/standardnormaltable.pdf )

So critical value Z = 1.75 is the closest value , but just barely.

But if you want a more accurate , use the normal function on Excel or from an online calculator or interpolate

If you interpolate

1.75 + (0.96–0.959954)*0.01/ (0.9608–0.95994)

Critical value Z= 1.750535

If you round to four digits,  critical value Z = 1.7505

So the interpolation isn’t that much more accurate

Excel function says critical value Z= 1.750686

=normsinv(0.96)

= 1.750686 which is probably more accurate.

Answer: ∠1 = 90°

Step-by-step explanation:

      There are a few steps we will take to solve this problem. In each step, I will write an equation to help us solve, then use inverse operations to solve.

      First, we will use the exterior angles theorem to find the measurement of ∠3 (this will help us solve for ∠2, then for ∠1).

89° = 51° + ∠3

∠3 = 38°

      Next, we will find the measurement of ∠2 since we know ∠2 plus ∠3 is 90 degrees, as shown by the perpendicular lines and the box.

90° = ∠3 + ∠2

90° = 38° + ∠2

∠2 = 52°

      Lastly, we will solve for ∠1. We know that there are 180 degrees in a triangle.

180° = 38° + ∠1 + ∠2

180° = 38° + ∠1 + 52°

180° = 90° + ∠1

∠1 = 90°

Answer:

90

Step-by-step explanation:

I started by finding angle 5

180 - 89 = 91  Supplemental angles

Then I found angle 3

The sum of the interior angles of a triangle is 180

180-89-91 = 38

Angle2 and 3 are complementary angles

90- 38 =52

the sum of the interior angles of a triangle is 180

Angle 1

180 - 52 - 38 = 90

The line m passing through the points (2, -7) and (4, -9) is parallel to the line y = -x + 2 , the correct option is (c) .

In the question ,

it is given that ,

the Line m passes through the points (2,-7) and (4,-9),

So , the slope of the line will be = (-9 + 7)/(4 - 2)

= -2/2

= -1

We know that the if two lines are parallel then they will have same slope ,

the slope of the line should be -1,

from the given options , we can see that only option (c) has the slope = -1

on comparing equation y = -x + 2 with the general equation of the line y = mx + c , we get

slope(m) = -1

hence , the line m is parallel to y = -x + 2 .

Therefore , the line m passing through the points (2, -7) and (4, -9) is parallel to the line y = -x + 2 .

Answer:

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

Step-by-step explanation:

Before we identify the equation of the line in slope intercept form, we must identify the slope intercept form equation. The slope intercept form equation is y = (m)x + (b) ⇒ m = slope of line; b = y-intercept of line.

To identify the equation of the line shown in slope intercept form, according to the slope intercept form equation, we need to identify the slope of the line and the y-intercept of the line. The slope of a line is the rate of a line, which advances up/down/side-to-side at a constant rate. The y-intercept of a line is the intersection of the line at the y-axis.

There is a specific formula for identifying the slope:

[tex]\boxed{\text{Slope} = \dfrac{\text{y coordinate of 2nd point - y coordinate of 1st point}}{\text{x coordinate of 2nd point - x coordinate of 1st point}}}[/tex]

Some facts about slope: The slope of a line will also depend on the graph. If the graph ascends upward to somewhere in Quadrant 1 or 2, the slope of the line will be positive. If the graph descends downward to somewhere in Quadrant 3 or 4, the slope will be negative. If the line horizontal and it passes perfectly through the x-axis, the slope of the line is 0. If the slope of the line is vertical, then the slope will be undefined.

Location of plotted points: First point: (0, -3); Second point: (2, 0)

Let us now identify the x and y coordinates of the plotted points:

[tex]\boxed{\text{y-coordinate of 2nd point = 0; y-coordinate of 1st point = -3}} \\ \boxed{\text{x-coordinate of 2nd point = 2; x-coordinate of 1st point = 0 }}[/tex]

Plug the coordinates into the slope formula to determine the slope:

[tex]\implies {\text{Slope} = \dfrac{\text{0 - (-3)}}{\text{2 - 0}}} = \dfrac{0 + 3}{2} = \dfrac{3}{2}[/tex]

Plug the slope of the line into the slope intercept form equation:

[tex]\implies y = (m)x + (b)[/tex]

[tex]\implies y = \huge\text{(}\dfrac{3}{2} \huge\text{)}x + (b)[/tex]

[tex]\implies y = \dfrac{3(x)}{2} + b[/tex]

Let us plug any point (that is on the line) for x and y. This will help us find the y-intercept (b). I will plug in the first point because it is my preference.

[tex]\implies y = \dfrac{3(x)}{2} + b[/tex]

[tex]\implies -3 = \dfrac{3(0)}{2} + b \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\text{First point: (0, -3)} \implies x = 0; y = -3]}[/tex]

[tex]\implies -3 = 0 + b[/tex]

[tex]\implies -3 = b[/tex]

Finally, let us substitute the slope of the line and the y-intercept of the line into the slope-intercept form equation. Then, we can simplify both sides of the equation and isolate the y-variable completely on the other side.

[tex]\implies y = (m)x + (b)[/tex]

[tex]\implies y = \huge\text{(}\dfrac{3}{2} \huge\text{)}x + (-3)[/tex]

[tex]\implies y = \dfrac{3x}{2} -3[/tex]

Therefore, the equation of the line in slope intercept form is y = 3x/2 - 3.

Add 1.657 and 0.64719 to get 2.30419.

2.30419−14.305296x=4.193x−3

Subtract 4.193x from both sides.

2.30419−14.305296x−4.193x=−3

Combine −14.305296x and −4.193x to get −18.498296x.

2.30419−18.498296x=−3

Subtract 2.30419 from both sides.

−18.498296x=−3−2.30419

This equation can be re-expressed as

f(x) = (3/4)ˣ

The x values on the table of values are given as: x = -2, -1, 0, 1 and 2

The next step is to substitute these values

So, we have the following equations

f(-2) = (3/4)⁻² = 16/9

f(-1) = (3/4)⁻¹ = 4/3

f(0) = (3/4)⁰ = 1

f(1) = (3/4)¹ = 3/4

f(2) = (3/4)² = 9/16
