Ten friends played slot machines in Las Vegas. Their average loss was $60 and the standard deviation of the loss was $10. What does the standard deviation of $10 mean
Using it's concept, it is found the standard deviation of $10 means that most students spent within $10 of the mean of $60 on the slot machines.
What is the standard deviation of a data-set?The standard deviation is given by the square root of the sum of the differences squared of each observation and the mean, divided by the one less than the number of values.It represents by around how much the distribution varies around the mean.Hence, in this problem, the standard deviation of $10 means that most students spent within $10 of the mean of $60 on the slot machines.

What is the equation of the line that passes through the point (1, 3) and is perpendicular to the line 2x + 3y = 15?
Answer:
first, we need to know the gradient of the line, 2x+3y=15
Gradient of the line is -2/3
from 3y=-2x+15
Y=-2x/3+5
Step-by-step explanation:
new gradient will be 3/2 since the initial gradient is perpendicular to the new one
therefore, considering the general equation of the line, y-y1=m(x-x1)
where y1=3 and x1=1
we can therefore substitute in the values into the above equation
so, y-3=3/2(x-1)
y-3=3x/2-3/2
2y-6=3x-3
2y-3x=-3+6
2y-3x=3
therefore, the equation of the line perpendicular to line 2x+3y=15 is 3x-2y=-3

The circumference of a circle is 9 pi cm. What is the area, in square centimeters? Express your answer in terms of \piπ.
Answer:
20.25 × pi cm²
Step-by-step explanation:
the circumference of a circle is
2×pi×r
with r being the radius.
in our case
9×pi = 2×pi×r
9 = 2r
r = 9/2 = 4.5 cm
the area of a circle is
pi×r²
in our case that is

Two angles are complementary.The larger angle is 30 degrees more than 4 times the smaller
angle find the measure of each angle
Define variables
Answer:
Step-by-step explanation:
Remark
2 angles are complementary means that 2 angles add up to 90°. That is the guiding princeple behind the problem.
Givens
Let the smallest angle = x
Let the largest angle = 4x + 30
Equation
4x + 30° + x = 90° Combine like terms on the left
Solution
5x + 30 = 90 Subtract 30 from both sides.
5x + 30 - 30 = 90 - 30 Combine
5x = 60 Divide both sides by 5
5x/5 = 60/5

What is the measure of angley to the nearest whole degree? 58° 64° 68° 73°
Applying the law of cosines, the measure of angle Y in the image below, to the nearest whole degree, is: B. 64°
What is the Law of Cosine:Law of cosines is given as: y² = x² + z² – 2xz(cosY)
Given the following:
x = 12
y = 16
z = 17
Y = ?
Apply the law of cosines:
16² = 12² + 17² – 2(12)(17)(cosY)
256 = 433 - 408(cos Y)
256 - 433 = -408(cos Y)
-177 = -408(cos Y)
-177/-408 = cos Y
Y = cos^(-1)(177/408)
Y ≈ 64°

The sections of a spinner are divided into five
equal sections and are lettered A to E. Myla spins
the pointer of the spinner once and rolls a number
cube numbered 1 to 6. What is the probability of
landing on B and rolling an even number?
Answer: 0.066, or a 6.6% Statistical Probability.
Step-by-step explanation:
When dealing with Statistical Probability, you are attempting to find the theoretical chance of an action occuring.
With the two actions described, one being a wheel with five set outcomes, and a dice with six set outcomes, you can find the probability of random numbers/outcomes by taking
[tex]\frac{1}{6} \\and\\\frac{1}{5}[/tex]
1/6 being number cube, 1-2-3-4-5-6
and
1/5 being spinner. A-B-C-D-E
In the Event, (made up by actions), it is described that The Cube AND Spinner are rolled and spun at random.
Also, The description asks: what is the probability of landing on B and rolling an even number?
So, the 1/6 chance of the dice becomes 1/3, or .33 or 33%.
And, the 1/5 chance for the spinner stays the same, because it is a single unit. So, probability of landing on B is still 1/5, or .2 or 20%.
When two actions are present in an Event, you are to procedurally multiply the outcomes by the decimal percentage, fraction, or actual percentage, to find the chance of occurence.
In this scenario, I used .2 x .33 and got 0.066
Which, equals 6.6%
I found this by multiplying the decimal percentage by 100, to scale the chance on a 100/100 based scale. In this case, the multiplier on the numerator is .066 ... creating 6.6/100, or .066 or 6.6%

Suppose that algeria has a workforce of 9,416,534, each of whom earns an average annual salary of (equivalent us dollars) $6,844. if the algerian government wishes to raise $9 billion in tax revenue, approximately where should it set the income tax rate? a. 9% b. 14% c. 18% d. 26% please select the best answer from the choices provided a b c d
The income tax rate is 14% if the Algerian government wishes to raise $9 billion in tax revenue and has a workforce of 9,416,534.
What is the income tax rate?It is defined as the tax rate applied on the solely earned money by a single entity.
Algeria has a workforce of 9,416,534
Each entity average annual salary = $6,844
The raise in tax revenue = $ 9 bilion
To find the income tax rate we must find the total income of the workforce,
= 9,416,534×6844
= $64.45 billion
Now for income tax:
[tex]\rm = \frac{Tax \ revenue}{Total \ income}[/tex]
[tex]=\rm \frac{9 \ billion}{64.45 \ billion}\times 100[/tex]
≈ 14 %
Thus, the income tax rate is 14% if the Algerian government wishes to raise $9 billion in tax revenue.

Damien has a newspaper delivery route. Every morning it takes him 12 minutes to organize his newspapers before he starts his delivery. Then, he delivers 3 newpapers every 2 minutes.
Write a function to represent the number of minutes, y, it takes Damien each day to deliver x newspapers, including the time it takes him to get organized. Enter your answer in the box.
Math
A function that represents the number of minutes it takes to deliver x newspapers is y = 12 + 2x/3.
What is the function?The function that represents the number of minutes it takes to deliver x newspapers is: total minutes = time it takes to orgainse the newspapers + time it takes to deliver x newspapers
Time it takes to orgainse the newspapers = 12 minutes
Time it takes to deliver x newspapers = 2x / 3

Problem 2
The diagonals of a kite meet at right angles. They also bisect each other. So the two triangles on the left and right side of the kite are congruent.
Because the smaller diagonal is bisected, you need only find the area of 1 of the triangles and double it.
1/2 of the smaller diagonal is the altitude of the triangle. The base is the other larger diagonal.
Solution
Area of the left triangle

altitude = 7.5
Base = 14 + 5 = 19
formula
Area = 1/2 * B * h

Additional comment
The "square" of a variable is that variable to the second power. The terms 2x or 4x are linear terms with the variable to the first power, do not represent the area of a square.
The equation A(x) = 4x² introduces a multiplier of 4 that is not applicable to the area of a square based on side length. (The formula might be useful if x represents the distance from one side to the center of the square, the radius of an inscribed circle, for example.)
