The probability that a student chosen at random will play an instrument other than drums is 31/36.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability can be defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
Total number of elements of sample space is 36.
Based on these results, express the probability that a student chosen at random will play an instrument other than drums as;

brown buttons. If four buttons are picked
at random, what is the probability that all
of them are black?
The probability that all of the buttons are black when four buttons are picked at random from a which jar contains four black buttons and three, is 1/35.
What is probability of an event?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
A jar contains four black buttons and three brown buttons. The total number of buttons is,
[tex]4+3=7[/tex]
The probability of picking a black button in the first attempt is,
[tex]P_1=\dfrac{4}{7}[/tex]
Now, there is total 6 buttons remain in which 3 are black buttons. Thus, the probability of picking black button in second attempt is,
[tex]P_2=\dfrac{3}{6}[/tex]
Similarly, for the third event,
[tex]P_3=\dfrac{2}{5}[/tex]
For the fourth event,
[tex]P_4=\dfrac{1}{4}[/tex]
The probability that all of them are black by the chain rule of probability,
[tex]P=\dfrac{4}{7}\times\dfrac{3}{6}\times\dfrac{2}{5}\times\dfrac{1}{4}\\P=\dfrac{1}{35}[/tex]

Of all rectangles with a perimeter of 12 which one has the maximum area
The rectangle maximum area will be A=9 square units with the length=3 and the width=3.
What is area of rectangle?Area is defined as the space occupied by a plane or rectangle having length and width in two dimensional plane.
It is given that the perimeter of rectangle is P=12
So from the formula of perimeter of rectangle
2(L+W)=12
L+W=6
L=6-W
Now the area of rectangle will be
A=LxW
A=(6-W)W
Now for maximum area we will find the derivative and equate to zero.
[tex]A=(6W-W^2})[/tex]
[tex]A'=6-2W=0[/tex]
[tex]W=3[/tex]
[tex]L=6-W=6-3=3[/tex]
So the area will be
[tex]A=3\times 3=9 \ square \ units[/tex]
Hence the rectangle maximum area will be A=9 square units with the length=3 and the width=3.

Find the slope-intercept form for the line satisfying the conditions.
Perpendicular to y=-1/2x+6, passing through the point (5,-4)
Answer:
LETS DO THIS!
Step-by-step explanation:
when a line is perpendicular the line is negative and reciprocal.y
y=2x+6
now we substitute.
-4=2(5)+b
-4=10+b
-14=b is your answer
Step-by-step explanation:
Hlew frnd!
To find the slope of the perpendicular line we just take the reciprocal and therefore change the sign of slope,
Perpendicular to y = -½x + 6
Hence, the slope will be = -½ = 2
Now we have to find the slope-intercept form, So
here y intercept is given and the point will be (0,b) then eqs. of line,
=> y = mx + b [slope-intercept form]
=> -4 = 2*5 + b
=> -4 = 10 + b
=> b = -14
What is the measure of ∠B?
Answer:
∠B=19°
Step-by-step explanation:
At the endpoints of a diameter, angle c meets the circle. It intercepts a 180-degree arc.We know that the measure of C is 90 degrees because the measure of an inscribed angle is half the measure of its intercepted arc. Angles of triangle of ABC must add up to 180.
m∠A+m∠B+m∠C= 180°
71°+m∠B+90°=180°
m∠B+161°=180°

Find the value of x
Thank you anyone helping
Answer:
x = 112°
Step-by-step explanation:
This figure shown is a pentagon. The total sum of degrees in a pentagon equals to 540° according to the formula (n - 2)180° where n is the number of sides. (5 - 2)180° = 3 × 180° = 540°.
To find x, we need to subtract all the given angles from 540°.
x = 540° - 130° - 118° - 105° - 75° = 112°
Answer:
x = 112°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 5 , then
sum = 180° × 3 = 540°
sum the interior angles and equate to 540°
105° + 118° + 75° + 130° = 540°
428° + x = 540° ( subtract 428° from both sides )
x = 112°

Answer:
xy = -1 and y = -1/x are the same.
They are not linear equations because they are not written in the form

Determine whether the equation below has a one solutions, no solutions, or an infinite number of solutions. Afterwards, determine two values of xx that support your conclusion.
x-5= -5+x
Since the two equations are of line and coincident to each other so the equations will have an infinite number of solutions.

You have a total amount of 36.75.
Since you are spending money you need to subtract.
We know that Marshall buys 3 tickets.
We also know that 'x represents the amount of a single ticket.
Remember that they are asking you for an algebraic expression and not an equation.
So you need to take away from your total, 36.75. And since you plan on buying three tickets and aren't given the amount x it leaves you with taking 3x from your total 36.75 or an other words
D. 36.75 - 3x
