Aubree recorded the grade-level and instrument of everyone in the middle school School of Rock below.
Seventh Grade Students
Instrument # of Students
Guitar 9
Bass 12
Drums 4
Keyboard 7
Eighth Grade Students
Instrument # of Students
Guitar 12
Bass 14
Drums 5
Keyboard 8
Based on these results, express the probability that a seventh grader chosen at random will play an instrument other than drums as a percent to the nearest whole number.
Answer:
88%
Step-by-step explanation:
probability of 7th grader playing other instruments apart from drum = total number of students not playing drum / population of the 7th grade class
total number of students not playing drum = 9 + 12 + 7 = 28
population of the 7th grade class = 28 + 4 = 32
28/32 = 0.875
to express in percentage multiply by 1000 = 87.5%
To round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.
88%
A drawer contains 30 pens of various colors: 4 are black, 10 are blue, 3 are red, 6 are green, 6 are blue and red, and 1 is white. A white pen is removed from the drawer.
Answer:
the probability in the case when the white pen would be removed from the drawer is 1 ÷ 30
Step-by-step explanation:
The computation of the probability in the case when the white pen would be removed from the drawer is given below
= Favorable outcome ÷ total outcome
= 1 ÷ 30
Hence, the probability in the case when the white pen would be removed from the drawer is 1 ÷ 30
We simply applied the above formula

Kianas soccer teams ratio of wins to losses is 5:3. Her team has played 24 games how many games have they won? 
Given:
Kianas soccer teams ratio of wins to losses is 5:3.
Her team has played 24 games.
To find:
The number of games they won.
Solution:
Let the number of games they won be 5x and the number of games they lost be 3x.
Total number of games is 24.
[tex]5x+3x=24[/tex]
[tex]8x=24[/tex]
[tex]x=\dfrac{24}{8}[/tex]
[tex]x=3[/tex]
Now, the number of games they won is:
Number of games they won = [tex]5x[/tex]
= [tex]5(3)[/tex]
= [tex]15[/tex]
Therefore, they won 15 games.

a rectangle is 12 feet longer than it is wide. Find the dimensions of the rectangle if the area is 220 sq ft
Width - x
Length - (x+12)
Area - x(x+12)
x(x+12)=220
x²+12x-220=0 -220 =22*(-10), 12=22-10
(x+22)(x-10)=0
x=-22, x=10
For width, we can use the only positive number,
so, the width is 10 feet.
Length is 10+12=22 feet.

right angle = 90, and we also have 42 so:
90+42=132
180-132=48
2nd one is weird, why is there a 150 down there? triangles add up to 180 nso right angle already gets 90 degrees.--oh wait I just got it, so that is the angle of the outer. we know a line is 180 degrees, so 180-150=30 so we found that degree
So now 90+30=120, 180-120=60
Find X, Y, Z,
(I believe X is 12?)
Answer:
x = 12 y = 24 z = 12[tex]\sqrt{3}[/tex]
Step-by-step explanation:
you are correct. x = 12
The dotted line has a length of 12 also
The dotted line is the shorter leg of the 30-60-90 triangle.
So, z = 12[tex]\sqrt{3}[/tex] and y = 24
is it true or false??
Answer:true
Step-by-step explanation:
It would be -6 which is less that -9

6cm
Step-by-step explanation:
I will apply equivalent fractions here or enlargement is also allowed
let find the factor,k
3/0.25=k

x=12*0.5
x=6cm
If the measure of arc ABC = 210°, what is the measure of AOC?
210
150°
100°
125°
The measure of m(arc AOC) equals to 150°.
What is the area of the sector?The area of the sector is -
A = θ/360 x πr²
Given is that the measure of arc ABC = 210°.
We can write measure of arc AOC as -
m(arc AOC) + m(arc ABC) = 360°
m(arc AOC) = 360 - 210
m(arc AOC) = 150°
Therefore, the measure of m(arc AOC) equals to 150°.

Answer:
may be A?? i dont really know bt i think A
Answer: B
Step-by-step explanation:
First, let's take the point of the origin so (0,0).
Let's substitute it back into the equations:
0 is x, 0 is y
A: 0> -1 true
B: 0 ≥ -1 also true
C: 0 < -1 not true
D: 0 ≤ -1 not true
So now, for C and D the region containing the (0,0) is the unwanted region (shaded) because the inequality is not true.
However, the graph has the side with point (0,0) unshaded.
So we know that the answer is A or B.
In linear programming signs <> are expressed as dotted lines and ≤≥ as unbroken lines.
The graph has an unbroken line so answer B is correct as it has the sign ≥ (representing an unbroken line) and satisfies the inequality.
