Answer:
Irrational Number: A number that cannot be written as a fraction
a
b
(where b ≠ 0), a repeating decimal, or a terminating decimal.
Rational Number: A number that can be written as a fraction
a
b
(where b ≠ 0), a repeating decimal, or a terminating decimal.
Repeating Decimal: A decimal where, when dividing, a digit or group of digits repeats without end in the quotient; there is a pattern in the digits that repeat without end.
Terminating Decimal: A decimal that, when dividing, ends with a remainder of zero.
Perfect cube: A number that is made by cubing a number: a3 = a • a • a.
Perfect square: A number that is made by squaring a number: a2 = a • a.
Cube Root:
if a3 = b, then a = 3√b
For principal square root this was the best I could do: The principle of square roots requires that the square root of the side with the unknown (x) only includes x without any exponent (other than 1). The simplest form that fits this criterion is: but x can also be an expression.
I hope this helps :3
If he needs $20, for a truck only has 10 and spends $2 already. He only has $8 left which means he needs a minimum of $12. So I'd say best guess. C or D.
Answer:
-0.6
Step-by-step explanation:
if you look and the x's, it shows that the numbers are going up by 5, if you look at the y's, it shows they are going down by 3.
put y over x. -3/5 = -0.6
Answer:
5 ; 2.07 ; 1.85
Step-by-step explanation:
Given the data:
2, 3, 5, 6, 7
The range : ( highest - lowest)
The range = (7 - 2) = 5
Sample standard deviation :
sqrt[Σ(x - m)²/ (n - 1)]
The mean (m) = Σx / n
n = sample size = 5
Σx / n ;
(2+3+5+6+7) / 5
= 23 / 5
= 4.6
[(2-4.6)^2 + (3-4.6)^2 +(5-4.6)^2 + (6-4.6)^2+ (7-4.6)^2] / (5 - 1)
= 17.2 / 4
= 4.3
Sqrt(4.3) = 2.07
Population standard deviation :
sqrt[Σ(x - m)²/ n]
The mean = m = 4.6
n = sample size = 5
[(2-4.6)^2 + (3-4.6)^2 +(5-4.6)^2 + (6-4.6)^2+ (7-4.6)^2] / 5
= sqrt(17.2 / 5)
= sqrt(3.44)
= 1.8547 = 1.85
Step-by-step explanation:
256,934
What is value of the digit 5
ten thousand
