How to Find the Mean
Add up all data values to get the sumCount the number of values in your data set Divide the sum by the countHow to Find the Median
Arrange data values from lowest to the highest value The median is the data value in the middle of the set If there are 2 data values in the middle the median is the mean of those 2 values.How to Find the Mode
Mode is the value or values in the data set that occurs most frequently.How to Find the Range

A school has a total of 280 seventh-
grade students. Based on the results
shown in the table above, how many
of those seventh-grade students
would you expect to be left-handed?
A 60
B 72
C 84
D 120
Answer:
c. 84 if wrong its 72 because im not sure if its esimated but if not its right.
Step-by-step explanation:
42x4.5=189
18x4.5=81
=270
84 of those seventh-grade students would you expect to be left-handed.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, have,
from 60 students ,
left handed = 18
now, from 280 students,
left handed = 280/60*18
=84
hence, 84 of those seventh-grade students would you expect to be left-handed.

What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The longest straw that can fit inside a 5-inch cylindrical cup, if the straw is placed at an angle in the cup, is 6 inches.
Then the approximate length of the cylinder's radius will be given by the Pythagoras theorem.
Let x be the length of the radius. Then we have
x² = 6² - 5²
x² = 36 - 25
x² = 11
x = √11
x = 3.316
x ≅ 3.3

Answer:
x = 21, ∠ ABE = 55°
Step-by-step explanation:
∠ ABD is right and
∠ ABE + ∠ DBE = ∠ ABD , that is
3x - 8 + x + 14 = 90
4x + 6 = 90 ( subtract 6 from both sides )
4x = 84 ( divide both sides by 4 )
x = 21
Then
∠ ABE = 3x - 8 = 3(21) - 8 = 63 - 8 = 55°

What is the value/expression for the side length highlighted in green.
Answer:
15
Step-by-step explanation:
The parallel lines divide the transversals proportionally.
The green length = 24 - c , then
[tex]\frac{24-c}{20}[/tex] = [tex]\frac{c}{12}[/tex] ( cross- multiply )
12(24 - c) = 20c ← distribute left side
288 - 12c = 20c ( add 12c to both sides )
288 = 32c ( divide both sides by 32 )
9 = c
Then
green length = 24 - 9 = 15
Miss Clara, the teacher at the school, has one
large classroom with 25 students. The
dimensions of the classroom are 30 units by
30 units. Each desk is two units wide by
three units long. How much space will be
leftover after all the desks are in the room?
Answer:
750 units.
Step-by-step explanation:
30 x 30 = 900 units (total space in the classroom)
2 x 3 = 6 units (how much space each desk takes up)
25 x 6 = 150 units (number of desks for each student)
900 - 150 = 750 units

Can’t get the answer right ? Anyone know what it is ???!??????
Answer:
Step-by-step explanation:
to find ∠QPS we need the arc SQ and RS we will take 1/2(RS-QS) = QPS
find QS :
360 = RS + RQ + QS
360 = 150 + 110 + QS
100 = QS
now plug into formula above
∠QPS = 1/2(150-100)
∠QPS = 1/2(50)
∠QPS = 25°

The two Integers are [tex]10,10.[/tex]
What is Integer ?An Integer number that can be written without a fractional component.
We have,
Sum of two Integers [tex]=20[/tex]
Product of two Integers [tex]=100[/tex]
Now,
Let,
One integer [tex]=x[/tex]
Another integer [tex]=y[/tex]
So,
According to the question,
[tex]x+y= 20[/tex] [tex].....(i)[/tex]
[tex]x*y=100[/tex]
⇒ [tex]x=\frac{100}{y}[/tex] [tex].....(ii)[/tex]
Now,
Putting value of x in equation (i),
We get,
[tex]\frac{100}{y}+y= 20[/tex]
[tex]100+y^2=20y[/tex]
[tex]y^2-20y+100=0[/tex]
Using middle term split method,
[tex]y^2-10y-10y+100=0[/tex]
[tex]y(y-10)-10(y-10)=0[/tex]
[tex](y-10) (y-10)=0[/tex]
We get,
[tex](y-10)=0[/tex] and [tex](y-10)=0[/tex]
So, [tex]y=10[/tex]
Now, putting value of y in in equation (i),
[tex]x+10=20[/tex]
[tex]x=10[/tex]
So, two integers are [tex]10,10.[/tex]
Hence, we can say that the two Integers are [tex]10,10.[/tex]

please help me otherwise I will fail , find the hypotenuse of traingle, which has base = 24 and perpendicular = 10
Answer:
26 is the hypotenuse
Step-by-step explanation:
a² + b² = c²
Given:
a = 24
b = 10
Work:
a² + b² = c²
24² + 10² = c²
576 + 100 = c²
c² = 676
[tex]\sqrt{c^2} =\sqrt{676}[/tex]
c = 26

Solution given:
by using Pythagoras law
hypotenuse ²=perpendicular ²+base².
hypotenuse ²=10²+24²
hypotenuse=√676=26

ASAP HELP PLS ASAP ASAP
Answer:
120cm2
Step-by-step explanation:
6 x 8 = 48cm2
8 x 9 = 72cm2
48 + 72 = 120cm2
Answer:
120 m^2
Step-by-step explanation:
The box on the left is 6m x 8m, thus the area would be 48 m^2.
The box on the right is 9m x 8m, thus the area would be 72 m^2.
Adding both areas would give you the total area of 120 m^2.
What is the length of the base of a triangle with a height of 7 and and area of 7?
Answer:
base = 2
Step-by-step explanation:
area = 1/2 base * height
7 = 1/2b * 7
7 = 7b/2
cross multiply
14 = 7b
divide both sides by 7
b = 2
Answer:
2
Step-by-step explanation:
So the formula for area of a right triangle is A=B*L*1/2
Variables to remember:
H=height
B=base
A=area
We know that 7=7*B* 1/2. Since they say area is 7, height is 7.
So, we know that L has to equal 1 to make 7*B=7
However, we must remember that this is *1/2. So to make area=7, we must get 14. To get 14, we must have 7*2*1/2, which would equal 14*1/2, equaling 7.
So the answer for B is:
2

A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 9cm, and the base has a radius of 4cm. How much water is needed to fill 150 cups? Use 3.14 for π, and do not round your answer.
Answer:
22608cm³
Step-by-step explanation:
Step 1
We find how many liters of water can be contained in 1 cup. We do this by finding the volume of the cup.
Cup is shaped as a cone
The volume of a cone = πr²h/3
Where
r = radius = 4cm
h = height = 9cm
π = 3.14
Hence,
Volume of the cone (cup) =
3.14 × 4² × 9/3
= 150.72 cm³
Step 1
How much water is needed to fill 150 cups?
1 cup = 150.72 cm³ of water
150 cups = x
Cross Multiply
x = 150 × 150.72 cm³
x = 22608 cm³ of water
Therefore, 22608cm³ of water is needed to fill 150 cups

What value of y makes this equation true? 8(y - 9) = 24
Answer:
12
Step-by-step explanation:
We know that 8x3=24, so we have to find what would equal 3 in the parenthesis.
12-9=3
The correct equation would be 8 (12-9) =24, or to be very simple, 8x3=24.
So y=12.

1. An account is opened with a balance of $2800
earning 4.25% simple interest. What will be the
balance in the account in 30 years?
Answer:
The simple interest in the account will be $3570 and the total amount including principle and simple Interest will be $6370Step-by-step explanation:
firstly ,
Given That
principal(p)=$2800
Rate(R)=4.25%
Time(T)=30 years
now , we have from formula
simple interest (S.I)= P × T ×R / 100
= (2800×30×4.25) / 100
= $3570
Therefore , Simple Interest in 30 years will be $3570
now , we know
Amount(A) = Principal (P) + Interest (I)
= $2800 + $3570
= $ 6370
Therefore the simple interest in 30 years will be $3570 and the total amount in the bank will be $6370 .
