Yup, the amount of 0's is the exponent. for example 1000= 10^3, hope this helped :)
Answer:
(a) 1, 2, 3, 6, 8
Step-by-step explanation:
Given
Required
The sequence of hours worked each day
<em>See attachment for options</em>
From the question, we understand that:
This means that, the middle number is 3 (when sorted)
So, we can conclude that (b) and (c) cannot be true because their middle numbers are 6 and 5 respectively
Next, is to determine the mean of (a) and (d)
The mean of a data is calculated as:
So, we have:
(a)
(d)
Option (a) is true, because it has:
Answer:
three (3)
Step-by-step explanation:
4x is the first term
-4 is the second term
3y is the third term
Answer:
The factorial of 11! is exactly 39916800
The number of trailing 0s in 11! is 2
The number of digits in 11 factorial is 8.
The factorial of 11 is calculated as below:
11! = 11 • 10 • 9 • 8 • 7 ... 3 • 2 • 1
Step-by-step explanation:
Answer:
Q1
|a-b| = b-a when a<b
Q2
104159/33000
Step-by-step explanation:
Q1
If a<b then a-b will always be negative. To get the absolute value, we can take -(a-b) = -a+b = b-a.
Q2
Let x = 3.12789789789...
We isolate the repeating decimal to start after the decimal, so we multiply by 100.
100x = 312.789789789...
We want to multiply by 10 for each digit that repeats (in this case 3), to get the repeating part to the left of the decimal.
100000x = 312789.789789
Subtracting the two...
x(100000-100) = 312789.789789 - 312.789789
99900x = 312477
x = 312477/99000 = 104159/33000
