The given numbers are:
5/4
√100
7.3
0.00247
√4/9
√2/24
0.01 with the line above the 1
Answers
Answer:
5/4 = rational √100 = rational 7.3 =rational 0.00247 = rational √4/9 = irrational √2/24 = irrational 0.01 (with the line) = irrational
Step-by-step explanation:
an irrational number is an infinitely repeating number that can not be written as a fraction, instead it must be written as a decimal. A rational number is a number that can be made by dividing two integers (an integer is a number with no fractional part).
The numbers are,
a. 5/4 = Rational
b. √100 = Rational
c. 7.3 = Rational
d. 0.00247 = Rational
e. √4/9 = Irrational
f. √2/24 = Irrational
g. 0.01 (with the line above the 1) = Irrational
What is Number system?
A system of writing to express the number is called number system.
Given that;
The numbers are,
5/4, √100 , 7.3 , 0.00247, √4/9 , √2/24 , 0.01 with the line above the 1.
Now,
Check the numbers as;
5/4 = 1.25
So, The number is a Rational number.
√100 = 10
So, The number is a Rational number.
7.3 = 7.3
So, The number is a Rational number.
0.00247 = 247/100000
So, The number is a Rational number.
√4/9 = 2/3 = 0.666.......
So, The number is a Irrational number.
√2/24
So, The number is a Irrational number.
0.01 with the line above the 1
So, The number is a Irrational number.
Thus, The numbers are,
a. 5/4 = Rational
b. √100 = Rational
c. 7.3 = Rational
d. 0.00247 = Rational
e. √4/9 = Rational
f. √2/24 = Irrational
g. 0.01 (with the line above the 1) = Irrational

How long will it take Scott to run 52 \text{ km}52 km52, start text, space, k, m, end text?
minutes
Answers
Answer:
Scott will take 221 minutes to run 52 km
Step-by-step explanation:
Speed
The speed of an object can be calculated with the formula:
[tex]\displaystyle v=\frac{d}{t}[/tex]
Where d is the distance traveled and t is the time taken.
Scott can run d=20 km in 85 minutes. Thus, his speed is:
[tex]\displaystyle v=\frac{20}{85}\ km/min[/tex]
Now he wants to know how many minutes it will take him to run d=52 km. Solving the formula for t:
[tex]\displaystyle t=\frac{d}{v}[/tex]
Since the speed has been already determined:
[tex]\displaystyle t=\frac{52}{\frac{20}{85}}[/tex]
Multiplying by the reciprocal of the denominator:
[tex]\displaystyle t=52*\frac{85}{20}[/tex]
t = 221 min
Scott will take 221 minutes to run 52 km
Answer:
221 min

3) The mean of a set of data is 4.68 and its standard deviation is 2.83. Find the z score for a value of 9.38.
Answers
Answer:
1.66
Step-by-step explanation:
The mean of a set of data is 4.68 and its standard deviation is 2.83. Find the z score for a value of 9.38
Given that :
Mean (m) = 4.68
Standard deviation (s) = 2.83
Value of x = 9.38
Zscore = (x - mean) / standard deviation
Zscore = (9.38 - 4.68) / 2.83
Zscore = 4.7 / 2.83
Zscore = 1.6607773
Hence, Zscore for a value of 9.38 is 1.66
