A campus radio station surveyed 500 students to determine the types of music they like. the survey revealed that 207 like rock, 172 like country, and 126 like jazz. moreover, 33 like rock and country, 27 like rock and jazz, 32 like country and jazz, and 13 like all three types of music. what is the probability that a randomly selected student likes at least two of the three types of music?
The probability that a randomly chosen student like at least two of the three styles of music will be 0.21.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
A school radio station polled 500 students to find out what kind of music they appreciate. According to the study, 207 people prefer rock, 172 prefer country, and 126 choose jazz. Furthermore, 33 like rock and country, 27 prefer rock and jazz, 32 prefer country and jazz, and 13 prefer all three forms of music.
The number of favorable events is given as,
Favorable events = 33 + 27 + 32 + 17
Favorable events = 105
Then the probability is given as,
P = 105 / 500
P = 0.21
P = 21%
The probability that a randomly chosen student like at least two of the three styles of music will be 0.21.

This circle is centered at the origin, and the length of its radius is 10. what is the circle's equation?
The equation of the circle that you are looking for is x^2 + y^2 = 100.
You can find this by using the base formula for a circle:
(x - x1)^2 + (y - y1)^2 = r^2
In which x1 is the x-coordinate of the origin, y1 is the y-coordinate of the origin, and r is the radius. So we put in the values we know and simplify.
(x -0)^2 + (y - 0)^2 = 10^2
x^2 + y^2 = 100
The equation of a circle centered at the origin such that the length of its radius is 10 units will be x² + y² = 100.
What is a circle?
Circle is a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).
Given is a circle is centered at the origin, and the length of its radius is 10 units.
The equation of the circle whose center is at origin is given by -
x² + y² = r²
We have radius [r] = 10 units
Therefore, we can write the equation of the circle as -
x² + y² = 10 x 10
x² + y² = 100
Therefore, the equation of a circle centered at the origin such that the length of its radius is 10 units will be x² + y² = 100.

The numerator of a fraction (which is in its simplest form) is 5 less than the denominator. If the numerator is multiplied by 2, and the denominator is increased by 16, then the fraction becomes smaller by 1/3 of it. Find the original fraction.
Final answer:
The original fraction, based on the provided conditions, is found to be 3/8 by setting up an equation relative to the changes described and solving for the unknown numerator and denominator.
Explanation:
The question involves solving for the numerator and denominator of a fraction based on provided conditions. Let's denote the denominator as x and the numerator as x - 5, since the numerator is 5 less than the denominator. According to the given conditions, when the numerator is multiplied by 2 and the denominator is increased by 16, the fraction becomes smaller by 1/3 of its original value.
Original fraction: [tex]\(\frac{x - 5}{x}\)[/tex]. After the modifications: [tex]\(\frac{2(x - 5)}{x + 16}\)[/tex]. The condition that the fraction becomes smaller by 1/3 of its original value leads to the equation: [tex]\(\frac{x - 5}{x} - \frac{1}{3} \cdot \frac{x - 5}{x} = \frac{2(x - 5)}{x + 16}\)[/tex].
Simplifying this equation, we first express the reduced original fraction as [tex]\(\frac{2(x - 5)}{3x}\)[/tex]. Then, setting it equal to the modified fraction, we get[tex]\(\frac{2(x - 5)}{3x} = \frac{2(x - 5)}{x + 16}\)[/tex]. Canceling out [tex]\(2(x - 5)\)[/tex] from both sides and solving for x, we find that x = 8. Therefore, the original denominator is 8, and the numerator is 3, making the original fraction 3/8.

The equation of plane with normal vector n = (1, 3, 4) passing through the point (4, −1, 3) in the scalar form is;
⇒ x + 3y + 4z = 13
What is Equation of plane?
A equation of plane containing the point (x₁ , y₁ , z₁) and having a normal vector (a, b, c) is defined as;
⇒ a (x - x₁) + b (y - y₁) + c (z - z₁) = 0
Given that;
The normal vector n = (1, 3, 4)
And, The point = (4, −1, 3)
Now,
Since, we know that;
A equation of plane containing the point (x₁ , y₁ , z₁) and having a normal vector (a, b, c) is defined as;
⇒ a (x - x₁) + b (y - y₁) + c (z - z₁) = 0
So, We get;
A equation of plane containing the point (4, −1, 3) and having a normal vector (1, 3, 4) is defined as;
⇒ a (x - x₁) + b (y - y₁) + c (z - z₁) = 0
⇒ 1 (x - 4) + 3 (y - (-1)) + 4 (z - 3) = 0
⇒ x - 4 + 3y + 3 + 4z - 12 = 0
⇒ x + 3y + 4z = 13
Thus, The equation of plane with normal vector n = (1, 3, 4) passing through the point (4, −1, 3) in the scalar form is;
⇒ x + 3y + 4z = 13

The price of a ticket was increase from 50p to 60p. What is the increase a as a fraction in its simple form? As a percentage of the original price?
Given is the price increase of a ticket from 50p to 60p.
Using the concept of fractions, we can find the ratio of new price to old price as follows :-
[tex] \frac{new \;\; price}{old \;\; price} = \frac{60p}{50p} =\frac{6}{5} [/tex]
So the increase in price is [tex] \frac{6}{5} [/tex] times old price of the ticket.
Using the formula of percentage, we can find the percentage change in price as follows :-
[tex] Percentage = \frac{(new\;\;price \;-\; old\;\;price) }{old \;\; price}*100 \\\\
Percentage = \frac{60p-50p}{50p}*100 \\\\
Percentage = \frac{10p}{50p}*100 \\\\
Percentage = 20\;\% [/tex]
Hence, Percentage increase is 20% of the original price.

Different types of parallelograms have distinguishing traits. Compare and contrast the rectangle, rhombus, and square based upon the characteristics of their angles. Which one(s) have angles whose sum is 360 degrees? Which one(s) have both pairs of opposite angles that are congruent? Which one(s) have four angles?
The square, rectangle, and rhombus are all considered parallelograms. Squares have four sides, four 90 degree angles, 2 pairs of opposite congruent angles (all the angles are congruent), the angles add up to a sum of 360 degrees. Rectangles have four sides, four 90 degree angles that add up to 360 degrees, 2 pairs of opposite congruent angles (all the angles are congruent). Rhombuses have four sides, four angles in total measuring up to 360 degrees no matter the combination of angles because the oposite angles are congruent (2 acute angles and two obtuse angles).
While the rhombus is the only shape within this trio to have a pair of congruent acute and a pair of congruent obtuse angles the square and rectangle both have 4 congruent angles. All 3 shapes have a sum of 360 degrees when the angles are added together, all 3 have pairs of opposite angles being congruent, and all 3 shapes have 4 angles in total.
HELP PLEASE! −3.64⋅|−5.3|−1.53 what is the anwser?
The expression simplifies to approximately -20.822. It involves multiplying -3.64 by the absolute value of -5.3 and then subtracting 1.53 from the result.
To calculate this expression, follow the order of operations (PEMDAS),
which stands for Parentheses, Exponents, Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).
In expression, there are no parentheses or exponents, so we proceed with multiplication and then subtraction:
-3.64 × |-5.3| - 1.53
Calculate the absolute value of -5.3, which is 5.3.
Multiply -3.64 by 5.3.
Finally, subtract 1.53 from the result.
-3.64 × 5.3 - 1.53
Now, do the multiplication:
-19.292 - 1.53
Now, subtract:
-19.292 - 1.53 = -20.822
Therefore, the answer for the given expression -3.64 × |-5.3| - 1.53 is approximately -20.822.

Spencer is 51 years younger than Holly seven years ago Holly's age was four times Spencer's age how old is Spencer now
Answer:
24
Step-by-step explanation:
The given age relationships can be used to reason about their ages.
__
When Holly was 4 times Spencer's age, the difference in their ages was 4-1=3 times Spencer's age. That is, Spencer was 51/3 = 17 years old, and Holly was 68.
That was 7 years ago, so Spencer is now 17+7 = 24 years old.
