Answer: <em><u>ratio</u></em>
(a Rational number is a number that can be written as a <u>ratio</u> of two integers)
Step-by-step explanation:
By definition a Rational number is that number that can be expressed as a fraction:
![\frac{a}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D)
Where the numerator "a" is an integer and the denominator "b" (
)
Then, in other words, a Rational number is a number that can be written as a ratio of two integers.
Since the denominator "b" can be
, we know that every Integer is a Rational number.
Below are some examples of Rational numbers:
-
is a Rational number, because it can be written as: ![\frac{6}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B1%7D)
is a Rational number, because it can be written as: ![\frac{5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D)
is a Rational number, because it can be written as: ![3=\frac{3}{1}](https://tex.z-dn.net/?f=3%3D%5Cfrac%7B3%7D%7B1%7D)
By law of the sine we have:
sine (x) / 38 = sine (35) / 22
Clearing we have:
sine (x) = (sine (35) / 22) * (38)
x = asine ((sine (35) / 22) * (38))
x = 82.18949277
Rounding:
x = 82.2 degrees
Answer:
The answer for this case is given by:
x = 82.2 degrees
option 4
Answer:
Broken = 7x
Step-by-step explanation:
Left = x
x(7x) = 30
(7x² = 30)⅐
x² = 4.285
√x² = √4.285
x = 2.07
Left = 2.07 meters
Broken = 7 x 2.07 = 14.49 meters
i hope this is correct!
good luck on ur test!
The first two pieces are the same, let each of those equal x, so you have x + x = 2x
The 3rd piece is the sum of the first two + 4, so this would be 2x + 4
Now you have 2x + 2x + 4 = 100 cm
Combine like terms:
4x +4 = 100
Subtract 4 from both sides
4x = 96
Divide both sides by 4
X = 24
First piece is 24 cm
Second piece is 24 cm
Third piece is 52 cm
Answer:
<h2>6.63</h2>
Step-by-step explanation:
Standard error of the mean is expressed as shown below.
SE = S/√n where;
S is the standard deviation
n is the sample suze
Given parameters
Standard deviation = $23.90
sample size = 13
Required
Standard error of the mean for this distribution.
Substituting the given value into the formula we have;
SE = 23.90/√13
SE = 23.90/3.6056
SE = 6.6286
<em>Hence the approximate standard error of the mean for this sample is 6.63</em>
