Second option: This is a perfect cube.
Fourth option: The side length is 6 centimeters.
Fifth option: Taking the cube root of the volume will determine the side length.
Step-by-step explanation:
You know that the volume of a cube can be calculated with:
Where s is the lenght of any side of the cube.
Since you know the volume of this cube, you can calculate the side lenght by solving for "s". You can make this taking the cube root of the volume.
Therefore, you get that the side lenght of this cube is:
(Since it has exact cube root, it is a perfect cube)
Answer:
d. S.D= 7.3
Step-by-step explanation:
x f f(x) x² f(x²)
75 2 150 5625 11250
80 3 240 6400 19200
85 2 170 7225 14450
90 2 180 8100 16200
95 0 0 9025 0
100 1 100 10000 10000
Sum f= 10 fx= 840 f(x²) = 71,100
Standard Deviation = √Sum fx² - (Sum f(x))²/sum f/ f
S.D= √71,100- (840)²/10/10
S.D= √71,100- 70560/10
S.D= √540/10
S.D= √54
S.D= 7.348 ≅7.3
Answer:
-1
Step-by-step explanation:
See Image below:)
The value of unknown number n is 47, wrote by Ms. Morales.
<h3>What is defined by the term expression?</h3>
In mathematics, an expression is a sentence that contains at least two digits or variables and with at least each math operation.
Addition, simple arithmetic, multiplication, or division are all examples of math operations.
- a) Constant: a numerical value that is fixed.
- b) Variables: they have no fixed values. Values are assigned based on the requirement.
- c) Terms: could be constants, variables, or variables multiplied by constants/ (s). Each word in an expression is denoted by a '+' or '-' sign.
For, the given condition in question;
Ms. Morales wrote the sum of 5 copies of some number n.
Then again,
He again wrote 2 copies of the same unknown number n.
The expression becomes;
n = 42 + 5
n = 47
Thus, the value of the unknown value is found as 47.
