65 people took a clarinet exam. Before the exam, 23 people predicted that they would pass, and the rest predicted they would fail. Of the people who predicted they would pass, 18 actually did. In total, 31 people passed the clarinet exam. What fraction of those who thought that they would fail actually did fail?
Answer:
The answer is 29/42
Step-by-step explanation:
First, let's calculate how many people predicted they would fail. The question states that 65 people took the exam and 23 predicted they would pass, so we can find the number of people that predicted they would fail by the following calculation:
Let FP be the people who predicted they'd fail
65 = 23 + FP
65 - 23 = FP
42 = FP
Now, let's move on to the next part. The question states that a total of 31 people passed the test, from those 18 being the people who predicted they would pass and the rest are people who had predicted they would fail but ended up passing.
Let's set x as the number of people who predicted they would fail but have passed.
31 = 18 + x
31 - 18 = x
13 = x
Since 13 of the 42 FP have passed, we can calculate how many of them failed. Let y be the number of people that predicted to fail and ended up failing:
13 + y = 42
y = 42 - 13
y = 29
Finally, now we have the fraction of those who predicted that they would fail actually did fail and that's 29/42
Assuming you are a business owner with different shareholders. How may zero growth stock valuation and constant stock valuation affect your business operations?
The ways that zero growth stock valuation can affect business operations is that:
When zero-growth model states that the dividend is at the same rate, it shows that one has no measure of growth in terms of dividends. This therefore shows that stock price is equal to the annual dividends and divided also by the needed rate of return.What ways does constant stock valuation affect business operations?The Constant stock valuation is known to be a kind of share evaluation as it states that the dividends paid by a firm will consistently increase at a constant growth rate.
This will help one to know especially investors on how to set or know the fair price that one needs to pay for a stock on daily basis today by due to future dividend payments.
The overall statement is that stock value affect one's business operations as the company's stock price is one that shows an investor perception of their capability to get profit and also if they can grow their profits in terms of future times.

The height of the tower based on the angle of elevation given is
How to calculate the height?From the information given, the tower is 45m, the clinometer is set at 1.3m above the ground, and the angle of elevation is 32°.
This can be illustrated as:
tan 32° = (45 - 1.3)/x
tan 32° = 43.7/x
x = 43.7/tan 32°
x = 69.93m.
Also, for triangle ACD,
tan 47° = (43.7 + y)/x
x × tan 47° = 43.7 + y
74.49 = 43.7 + y
y = 31.29
The height of the tower will be:
= 43.7 + 31.29
= 74.99m

If 10 inches on a map represents an actual distance of 100 feet, then what
actual distance does 25 inches on the map represent?
According to the given conditions, state:
10 × 100 = 25 ÷ xIf the fraction is defined, then the denominator cannot equal 0:
x≠0Attach the inequality as the domain: x≠0
Reduce the fraction to the smallest term, canceling the greatest common factor: 1/10 = 25/x.
Multiply both sides of the equation by the common denominator:
10x/10 = 25 × 10x / xSimplify the fractions: x = 250
Find the intersection: x = 250
get the result: x = 250
Answer: x = 250
the actual distance would be 250 feet.

Write the equation of a sine or cosine function to describe the graph.
Step-by-step explanation:
The equation of a trigonometric function is
[tex]y = a \sin(bx + c) + d[/tex]
or
[tex]y = a \: cos(bx + c) + d[/tex]
Let define some variables,
D is the midline, this refers to the midpoint of the highest y value and lowest y value. Some textbooks call it the vertical translations but it is the same thing.
A is the amplitude. The amplitude is the distance from the midline to the highest y value. Some distance is non negative, the formula for the amplitude is
[tex] |a| [/tex]
The period is how often the wave repeats itself on a interval.
Period can't be negative so the formula for period is
[tex] \frac{2 \pi}{ |b| } [/tex]
To find the period, look at the extreme points.
The phase shift tells us if the sinusoid have been shifted to the right or left. The formula for the phase shift
[tex]bx + c = 0[/tex]
Solving for x gives us
[tex]x = \frac{ - c}{b} [/tex]
If our x is negative, we have a phase shift to the right
If our x is Positve, we have a phase shift to the left.
Let solve this equation, Let use Sine since sin(0)=0,
The smallest y value here is 0, and the highest is 2, so the amplitude is 1.
[tex]d = 1[/tex]
Next, the distance from the max to the midline is 1, as well the min to the midline is also 1.
So
[tex]a = 1[/tex]
We have minimum at 0, and 8, so our period is 8.
[tex] \frac{2\pi}{b} = 8[/tex]
Solve for b,
[tex] \frac{\pi}{4} = b[/tex]
Plug this in the equation.
[tex]1 \sin( \frac{\pi}{4} x) + [/tex]
[tex]y = \sin( \frac{\pi}{4} x) + 1[/tex]
The graph passes through (4,2) so let see if that holds true for our equation
[tex]2 = \sin( \frac{\pi}{4} (4)) + 1[/tex]
[tex]2 = \sin(\pi) + 1[/tex]
[tex]2 = 0 + 1[/tex]
[tex]2 = 1[/tex]
This doesn't hold true, so we must have a phase shift
Notice that
[tex] \sin( \frac{\pi}{2} ) = 1[/tex]
So if we shift this pi/2 to the right, we can get our equation to be true.
[tex]y = \sin( \frac{\pi}{4} x - \frac{\pi}{2} ) + 1[/tex]
This equation works so our equation is
[tex]y = \sin( \frac{\pi}{4} x - \frac{\pi}{2} ) + 1[/tex]

What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have a quadrilateral PQRS shown in the picture.
From the transformation:
The image of Q(x, y) = Q'(-x, -y) will be the highest and leftmost point following the rotation since Point S is the lowest and farthest point to the right of Point Q.
The same applies to points P P' and R R'.

The curve is of increasing order so the tangent and secant having equal slope only possible at the boundaries of the curve.

The functions (2), (3), (4), (5) and (6) are linear functions.
So, their domain and range are (−∞,∞)

Write an equation in slope-intercept form of the line that passes through the point (3,-2) with slope -2.
Answer:
D
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - 2 , then
y = - 2x + c ← is the partial equation
to find c substitute (3, - 2 ) into the partial equation
- 2 = - 6 + c ⇒ c = - 2 + 6 = 4
y = - 2x + 4 ← equation of line in slope- intercept form
