Step-by-step explanation:
Mean of Group A is greater than the mean of group B. The mean absolute deviation for the group A and B is 3. The different between the mean is 6 (15 - 9)
Number of mean absolute deviations is :
Difference between mean of two groups / MAD

Answer:
67.5
Step-by-step explanation:
b times h
7.5 times 9
Answer:
A = 67.5 in²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 9 and h = 7.5 , then
A = 9 × 7.5 = 67.5 in²
Alicia bought a new game that was 15% off. The discount took 4.65. What was the original price of the shirt?
Answer:
If 31 is a option I would pick it.
Step-by-step explanation:
The problem we are solving is:
15% of ____ is 4.65.
This means that 0.15 x ? = 4.65
So ? = 4.65 / 0.15
Therefore ? = 31.
So the original number is 31.

Answer:
9/10 or 0.9
Step-by-step explanation:
When adding fractions, you look at each of them as an equal number, or a whole.
25+36
91
So, now all we have to do is convert it to it's closest form. (In tenths, since we are adding tenths.)
90
And it would be 9/10, or 0.9

how do you solve this ?
Answer:
x = 37 mm
Step-by-step explanation:
using the Pythagorean theorem:
m² = 13² - 5² = 169 - 25 = 144
m = √144 = 12 mm
x² = 12² + 35² = 144 + 1225 = 1369
x = √1369 = 37 mm
Answer:
x=37.3
Step-by-step explanation:
Since we're looking for "x" we need to use "the Pythagorean theorem".
13mm will be our "A" and 35mm will be our "B" will "x" being the hypotenuse.
Since x is the hypotenuse, it needs to be a number greater than 13 and 35.
c=√(a² + b²)
Making it c=√(13² + 35²)
Making C=37.336 or 37.3
Therefore making, x=37.3

The length of a rectangle is three times its width. If the perimeter is 120 inches, what is the length? The width?
Answer:
Length=45 inches, width=15 inches
Step-by-step explanation:
Length=3w
Width=w
Can be written as 3w+w+3w+w
Combine like terms to get 8w
120/8=15
w=15
Width=15 inches
Length=3(15)=45
Length=45 inches
Find the area of the trapezoid
Answer:
42 square units
Step-by-step explanation:
Each square on the grid is 2 units by 2 units.
Bases: OC = 10; SK = 4
Height: OS = 6
area = (b1 + b2)h/2
area = (10 + 4)(6)/2
area = 42
Answer: 42 square units
Answer:
The area of trapezoid is 42 square unit.
Step-by-step explanation:
According to the question
A trapezoid which is consist of many square shapes and each grid square equals 2 units . We need to find the area of trapezoid.
To calculate the area of trapezoid we have given :-
Base ; SK = 4 and OC = 10Height ; OS = 6Formula for finding area of trapezoid is ½ × (Base 1 + Base 2) × Height .Finding the area of trapezoid :-
Area of trapezoid = ½ × ( 4 + 10 ) × 6
Add 4 and 10.Area of trapezoid = ½ × 14 × 6
Multiply 14 by 10.Area of trapezoid = ½ × 84
Divide by 2.Area of trapezoid = 42
Hence,
The area of trapezoid is 42 square unit.

Your portfolio must include a minimum of the following five types of equations and solutions:
Two one-step equations
Two equations that contains fractions
One equation with distributive property
One equation with decimals
One real-world problem that is solved by an equation
Remember that each equation must include at least one variable. Once you have created each equation, you will solve it and show your work. Pretend that you are teaching the equations to a new pre-algebra student. Or you can actually teach them to a sibling or friend!

7). Natalie buys organic almonds priced at $77 from the grocery store. How much did
she pay the cashier, if she received $23 in change?
Step-by-step explanation:
1. add 4 on both sides and it will be x=17
2. subtract 17 on both sides and it will be x= 34
3. multiply 9/7 on both sides and it will be x= 257/7 then you divide 257 by 7 then the final answer will be x= 36
4. multiply 3/2 on both sides and it will be x=6/2 then you divide 6 from 2 and the finial answer will be x= 3
5. you will distribute 3 into x and 2 and you will be 3x-6=-9 then you will add 6 on both sides so you will get 3x=3 and then divide 3 on both side so you will get x=1
6. add 1.75 on both sides so x= 10.6
7. the equation will be 23 +x = 77 so first you will subtract 23 on both sides and x will equal 54 so Natalie paid $54

Julio recibió $640.000: gastó las ⅜ partes para pagar sus estudios y la ¼ parte para reparar el auto, ¿cuánto dinero le queda?
Answer:
Resto= $240.000
Step-by-step explanation:
Dada la siguiente información:
Cantidad total de dinero= $640.000
Costo de estudio= 3/8= 0,375
Costo de auto= 1/4= 0,25
Primero debemos calcular la cantidad total gastada, y después la diferencia:
Costo de estudio= 0,375*640.000= 240.000
Costo de auto= 0,25*640.000= 160.000
Gasto total= $400.000
Resto= 640.000 - 400.000
Resto= $240.000
To solve for x in the equation x + 3 = 5, you would...
answer/ step-by-step explanation:
hi there!
the question is asking us to solve for x for the equation
x + 3 = 5
first we need to get all the numbers on to one side of the equal sign while the other side has all the variable
in order to do that we need to subtract 3 on both sides
x + 3 = 5
- 3 - 3
and that leaves us with our answer!
x = 2
