The probability that a student chosen randomly from the class does not play an instrument is, 6/22.
What are sets and subsets?A set is a collection of well-defined objects.
A subset contains all the elements or a few elements of the given set.
The improper subset is when it contains all the elements of the given set and the proper subset is when it doesn't contain all the elements of the given set.
Given, n(U) = 22, n(I) = 15, n(S) = 11 and n(I∩S) = 9.
We know, n(IUS) = n(I) + n(S) - n(I∩S).
n(IUS) = 15 + 11 - 9.
n(IUS) = 17.
So, The number of people does not play an instrument is
n(S - I) = n(S) - n(S∩I) = 15 - 9 = 6.
Therefore, The probability that a student is chosen randomly from the class does not play an instrument is,
= 6/22.

Answer:
parallel: y = -7x -44perpendicular: y = 1/7x -8/7Step-by-step explanation:
The given equation is in slope-intercept form:
y = mx +b . . . . . . line with slope m and y-intercept b
For the purpose of this question, you need to recognize that the line with equation ...
y = -7x +8
has a slope (x-coefficient) of -7.
The parallel line will have the same slope (x-coefficient).
The perpendicular line will have a slope that is the opposite reciprocal of this:
m = -1/(-7) = 1/7
Each line will have a y-intercept (b) that makes the line go through the given point. The y-intercept can be found by solving the slope-intercept equation for b:
b = y - mx . . . . . . where (x, y) is the point you want the line to go through
__
parallel line:
b = -2 -(-7)(-6) = -2 -42 = -44
The equation of the parallel line is y = -7x -44.
__
perpendicular line:
b = -2 -(1/7)(-6) = -14/7 +6/7 = -8/7
The equation of the perpendicular line is y = 1/7x -8/7.

solve the inequality 3x-5<10
Answer:
answer is 5
Step-by-step explanation:
am 100% sure lol
Answer:
x < 5
Step-by-step explanation:
3x - 5 < 10
[make x the subject of the formula]
3x < 10 + 5
3x < 15
[divide both sides of the equation by 3]
3x / 3 < 15 / 3
x < 15 / 3
x < 5

Answer:
220%
Step-by-step explanation:
The percentage change is computed by ...
% change = ((new value)/(old value) -1) × 100%
= (800/250 -1) × 100% = (3.2 -1) × 100%
= 220%
The increase was 220%.

24x - 10 = -12x + 40, What would be the coefficient of x if the variables were moved to the left side of the equation?
Answer:
25/18
Step-by-step explanation:
24x - 10 = -12x + 40
<=> 24x + 12x = 40 + 10
<=> 36x = 50
<=> x = 50/36
<=> x= 25/18

(x + 2)(x + 3)(x + 4) can be written in the form x + ax² + bx + c
where a, b and care positive integers.
Work out the values of a, b and c.
Answer:
[tex]a=9, b=26, c=24[/tex]
Step-by-step explanation:
Let's expand the expression bit by bit.
[tex](x+2)(x+3)=(x)(x)+(x)(3)+(2)(x)+(2)(3)=x^2+5x+6[/tex] by FOIL.
We have that [tex](x^2+5x+6)(x+4)=x(x^2+5x+6)+4(x^2+5x+6)=x^3+5x^2+6x+4x^2+20x+24=x^3+9x^2+26x+24[/tex].
So, the answer is [tex]\boxed{a=9, b=26, c=24}[/tex]
A cubic polynomial is a type of polynomial with the degree of 3 i.e. the highest exponent of the variable is 3.
The general form of a cubic polynomial is written as p(x): ax³ + bx² + cx + d, a ≠ 0, where a, b, and c are coefficients and d is the constant with all of them being real numbers.
Given:
(x + 2)(x + 3)(x + 4)
Now, Multiplying the monomial
= (x² + 2x + 3x+ 6 ) ( x+4)
= (x² + 5x+ 6 ) ( x+4)
= x³ + 4x² + 5x² + 20x + 6x+ 24
= x³ + 9x² + 26x+ 24
Now, Comparing it with the standard form of cubic Polynomial
ax³ + bx² + cx + d
So, a= 1, b= 9, c= 26 and d= 24.

Step-by-step explanation:
Find the equation of a line that is perpendicular to the line x=-9 and contains the point (-8,1)
Step-by-step explanation:
the line x = -9 had only one valid x value (-9), but then all values for y between -infinity and +infinity are valid.
does this sound familiar ?
it should, because the y-axis is the same type of line.
it is x = 0.
so, x = -9 is simply parallel to the y-axis.
and any line perpendicular to it (crosses the original line in a right angle = 90 degrees) is then parallel to the x-axis.
there the situation is upside-down: there is only one valid y value, and all values between -infinity and +infinity are valid x values.
since the specified point on that line has y = 1, it means that the whole line is
y = 1
