If the average crowdfunding campaign investment is about $90 and the average number of investors is about 80, what is the best approximation of the average amount raised in a crowdfunding campaign?
Answer:
A) $7200
Step-by-step explanation:
The required average amount raised in a crowdfunding campaign is $7200.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 12×2 = 24
The average crowdfunding campaign investment is about $90 and the average number of investors is about 80 which is given in the question.
To determine the average amount raised in a crowdfunding campaign.
The required average amount raised in a crowdfunding campaign is the product of the average crowdfunding campaign investment and the number of investors.
As per the given information,
The average amount raised = $90 × 80 = $7200
Therefore, the required average amount raised in a crowdfunding campaign is $7200.

Find the slope of the line that contains the following points.
slope is difference of the y-axis over difference of x-axis.
a. slope=
[tex] \frac{8 - ( - 12)}{17 - 17 } [/tex]
=infinity♾️ =tan 90°
b. slope=
[tex] \frac{ - 2 - 1}{ 6 - ( - 3)} [/tex]
= -3/9 = -1/3
Solve the system by substitution.
y = -4x
23 - 5y = 44
[tex] \begin{cases} y = - 4x \\ 23 - 5y = 44 \end{cases}[/tex]
Substitute y = -4x in the second equation.[tex]23 - 5( - 4x) = 44 \\ 23 + 20x = 44 \\ 20x = 44 - 23 \\ 20x = 21 \\ x = \frac{21}{20} [/tex]
Substitute the value of x in any given equations. I will substitute the value of x in the first equation.[tex]y = - 4x \Longrightarrow y = - 4( \frac{21}{20} ) \\ y = \cancel{ - 4}( \frac{21}{ \cancel{20}} ) \Longrightarrow y = - \frac{21}{5} \\ y = - \frac{21}{5} [/tex]
Answer Check by substituting both values in two equations.First Equation
[tex]y = - 4x \Longrightarrow - \frac{21}{5} = - 4( \frac{21}{20} ) \\ - \frac{21}{5} = \cancel{ - 4}( \frac{21}{ \cancel{20}} ) \\ - \frac{21}{5} = - \frac{21}{5} \: \: \: \checkmark[/tex]
Second Equation
[tex]23 - 5y = 44 \\ 23 - 5( - \frac{21}{5} ) = 44 \\23 - \cancel{5}( - \frac{21}{ \cancel{5}} ) = 44 \\ 23 + 21 = 44 \\ 44 = 44 \: \: \: \: \checkmark[/tex]
Both equations are true for the value of x and value of y.
Answer[tex] \begin{cases} x = \frac{21}{20} \\ y = - \frac{21}{5} \end{cases}[/tex]

Which type of angle is Angle A B C?
Angle A B C is a straight angle.
Angle A B C is a vertical angle.
Angle A B C is a right angle.
Angle A B C is a complementary angle.
Answer:
Angle ABC is a right angle. So option C is correct.
What is the right triangle?
A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.
The angle of a right angle is always 90 degrees.
IT is given that the Angle A B C is intersected by a line to form angles 25 degrees and 65 degrees.
If we add up 25 and 65 degrees, we get 90 degrees.
25 + 65 = 90
Thus, Angle ABC is a right angle because right angles are 90 degrees.
Therefore Angle ABC is a right angle. So option C is correct.

Find the measure of the arc or angle indicated
Step-by-step explanation:
Let O be the center of the circle
We have Angle YOW = 125°
and Angle WOX = 121°.
Therefore Angle YOX = 360° - 125° - 121° = 114°.
(Sum of angles around a point is 360°)
Since Angle at Center = 2 * Angle at Circumference,
Angle YWX
= 0.5 * Angle YOX = 0.5 * 114° = 57°. (A)

The graph shows the function f(x) = (2.5)x was horizontally translated left by a value of h to get the function g(x) = (2.5)x–h.
On a coordinate plane, 2 exponential functions are shown. f (x) approaches y = 0 in quadrant 2 and increases into quadrant 1. It goes through (negative 1, 0.5) and crosses the y-axis at (0, 1). g (x) approaches y = 0 in quadrant 2 and increases into quadrant 1. It goes through (negative 2, 1) and crosses the y-axis at (0, 6).

Using translation concepts, it is found that the value of h is 5. so option D is correct.
What is a translation?A translation can be represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
When the expression of function is such that it involves the input to be present as exponent of some constant, then such function is called exponential function.
In this problem, function f(x) is defined by:
[tex]f(x) = (2.5)^x[/tex]
Function g(x) is defined by
[tex]g(x) = (2.5)^x-h[/tex]
OR
[tex]g(x) = (2.5)^x + g[/tex]
Since f(x) the y-axis at (0,1), while g(x) crosses it at (0,6), which means that g(x) is f(x) added to 5, hence h = 5.
Using translation concepts, it is found that the value of h is 5. so option D is correct.

What percentage of seniors chose the prom theme "Into the Future?"
OA. 52.78%
OB. 65%
OC. 68.42%
OD. 36.11%
Answer: 65%
Step-by-step explanation:
130% of 200 is 65%
65% of seniors chose the prom theme "Into the Future.
What is a frequency table?A frequency table is a list of objects with the frequency of each item shown in the table.
The frequency of an occurrence or a value is the number of times it happens.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
Given,
Total number of seniors = 200
The number of seniors chose the prom theme "Into the Future = 130
Percentage = (number of seniors who chose the prom theme "Into the Future ÷ Total number of seniors )100
Percentage = (130/200)100
Percentage = 65%.
Hence "65% of seniors chose the prom theme "Into the Future".
