Using it's concept, it is found that there is a [tex]\frac{17}{23}[/tex] probability that a seventh grader chosen at random will play an instrument other than drums.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
There is a total of 6 + 4 + 6 + 7 = 23 seventh graders.Of those, 23 - 6 = 17 play instruments that are not the drum.Hence:
[tex]p = \frac{17}{23}[/tex]

Given circle O with diameter AB find x
A circle is a curve sketched out by a point moving in a plane. The measure of x is 60°.
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
Given that the measure of the arc AC is 120°. Now, as we know, the diameter divides the circle into two equal chords of 180° each. Therefore, the measure of x can be written as,
[tex]x = {\rm arcAB-arc AC}\\\\x = 180^o-120^o\\\\x = 60^o[/tex]
Hence, the measure of x is 60°.

Consider this dilation.
Hint: Remember the notation for the original figure and the figure after it has undergone transformation.
(a) Is the image of the dilation a reduction or an enlargement of the original figure? Explain.
(b) What is the scale factor? Explain and show your work.
Answer:
(a) Reduction
(b) scale factor = 1/2
Step-by-step explanation:
(a) A reduction is a dilation that creates a smaller image.
As A'B'C'D' is smaller than ABCD, image A'B'C'D' is a reduction of image ABCD.
(b) To find the scale factor:
find the center of dilation by connecting the corresponding points from the original and dilated image and finding where these lines intersect (see attached image)measure from the center of dilation to a point on the original image.measure from the center of dilation to the corresponding point on the dilated image.Divide the distance to the dilated image by the distance to the original image.center of dilation = (0, 0)
(0, 0) to point C = 4 units
(0, 0) to point C' = 2 units
⇒ scale factor = 2/4 = 1/2

Urgent. There are 12 coloured counters in a bag. The counters are black, white or grey A counter is chosen at random. The probability that the counter is not black is 3/4. The probability that the counter is not white is 2/3. Work out the probability that the counter is grey.
Answer:
1/12
Step-by-step explanation:
Needed information
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
The sum of the probabilities of all outcomes must equal 1
Solution
We are told that the probability that the counter is not black is 3/4.
As the sum of the probabilities of all outcomes must equal 1, we can work out the probability that the counter is black by subtracting 3/4 from 1:
[tex]\sf P(counter\:not\:black)=\dfrac34[/tex]
[tex]\implies \sf P(counter\:black)=1-\dfrac34=\dfrac14[/tex]
We are told that the probability that the counter is not white is 2/3.
As the sum of the probabilities of all outcomes must equal 1, we can work out the probability that the counter is white by subtracting 2/3 from 1:
[tex]\sf P(counter\:not\:white)=\dfrac23[/tex]
[tex]\implies \sf P(counter\:white)=1-\dfrac23=\dfrac13[/tex]
We are told that there are black, white and grey counters in the bag. We also know that the sum of the probabilities of all outcomes must equal 1. Therefore, we can work out the probability the counter is grey by subtracting the probability the counter is black and the probability the counter is white from 1:
[tex]\begin{aligned}\sf P(counter\:grey) & = \sf1-P(counter\:black)-P(counter\:white)\\\\ & =\sf 1-\dfrac14-\dfrac13\\\\ & = \sf \dfrac{12}{12}-\dfrac{3}{12}-\dfrac{4}{12}\\\\ & = \sf \dfrac{12-3-4}{12}\\\\ & = \sf \dfrac{5}{12}\end{aligned}[/tex]

Answer:
30°
Explanation:
∠LMP + ∠PMN = 180°
[∠LMO + ∠OMP] + [∠PMR + ∠RMN] = 180°
FIND x
(x - 10) + (x + 30) + x + 40 = 180
3x - 10 + 30 + 40 = 180
3x + 60 = 180
3x = 120
x =40
FIND ∠LMO
∠LMO = x - 10
∠LMO = (40) - 10
∠LMO = 30°
Hope this helps and God bless!
Answer:
∠LMO = 30°
Step-by-step explanation:
Angles on a straight line add up to 180°
⇒ (x - 10)° + (x + 30)° + 40° + x° = 180°
⇒ x° + x° + x° - 10° + 30° + 40° = 180°
⇒ 3x° + 60° = 180°
⇒ 3x° = 120°
⇒ x = 40
Substitute found value of x into the expression for ∠LMO:
⇒ ∠LMO = (40 - 10)°
⇒ ∠LMO = 30°

What is the area of the triangle figure?
The area of the triangle is equal to 12 mm².
Area of triangle
The area of a triangle is given by the formula:[tex]A=\frac{bh}{2}[/tex], where:
b= length of the base;
h=height
STEP 1 - Find the dimensions for the base and the height of the triangle.From the figure, it is possible to see that h= base of rectangle - 4 mm. Then, the height of the triangle(h)= 10-4=6 mm.
You can see that the sum of the base of the triangle with the height of the rectangle is equal to 12 mm. The figure also shows that the height of this rectangle is equal to 8 mm. Thus, the base of the triangle(h)= 12-8=4 mm.
STEP 2 - Find the area of the triangle.
From step 1:
b= length of the base= 4
h=height=6
Therefore, the area of the triangle - [tex]A=\frac{bh}{2}=\frac{4 * 6}{2}=\frac{24}{2} =12 mm^2[/tex].

Answer:
30 inches
Step-by-step explanation:
In equilateral triangle all sides are equal. One side of the triangle EB is also the side of a square.
So, all the sides of the square is 6 inches
Perimeter = sum of all sides
= AB + BC + CD + DE + EA
= 6 + 6 + 6 + 6 + 6
= 5*6
= 30 inches
Answer:
Here,
length of the square BCDE(l)= 6 inches
Also,
length of the equilateral triangle ABE(l)=6 inches
Lastly, Perimeter of figure ABCDE= 5*6
=30 inches
or,Perimeter of the figure ABCDE also=
AB+BC+CD+DE+EA
=6+6+6+6+6
=30inches
Step-by-step explanation:
We know,
length DC of the square BCDE(l)=6inches
So,
DC=BC=BE=DE (All sides of a square are equal)
Again,
length BE of the equilateral triangle ABE=6inches
So,
BE=AB=AE (All sides of a equilateral triangle are equal)
Therefore, Perimeter of figure ABCDE=
AB+BC+CD+DE+EA or, 5*6
(perimeter means to sum all the outer sides a given polygon, in this case it's a Pentagon)
