<u>Answer-</u>
<em>The printer used </em><em>642 digits</em><em> to print all the pages in the book.</em>
<u>Solution-</u>
There are 250 pages numbered starting from 1 to 250.
The total number of digits would be the sum of digits of all single digits from 1 to 9, all double digits number from 10 to 99, and all triple digits number from 100 to 250.
There are 9 single digit numbers from 0 to 9, 90 double digit numbers from 10 to 99, and 151 triple digit numbers from 100 to 250.
So,
![\text{Total digits}=(1\times 9)+(2\times 90)+(3\times 151)\\\\=9+180+453\\\\=642](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20digits%7D%3D%281%5Ctimes%209%29%2B%282%5Ctimes%2090%29%2B%283%5Ctimes%20151%29%5C%5C%5C%5C%3D9%2B180%2B453%5C%5C%5C%5C%3D642)
Therefore, the printer used 642 digits to print all the pages in the book.
Answer:
Correct answer is C.
Step-by-step explanation:
m + 3s = 50
the total number of questions is 20. since the paper is made of only multiple choice and short answer questions, the sum of the multiple choice and short answer questions should be 20.
since multiple choice is 'm' and short answer is 's'
then m + s = 20
but theres no option for that
if we take the number of points
points for 1 multiple choice question - 1
then points for m number of multiple choice questions = 1 * m = m
points for 1 short answer - 3
then points for s number of short answer question = 3 * s = 3s
then total number of points = m + 3s
and the total number of points = 50
therefore
m + 3s = 50
this is the correct answer C.
Answer:
As in explanation.
Step-by-step explanation:
A) SSE means "Error Sum of Squares". The source of it is the sum of squared deviations within groups.
B) SSTR means "Treatment Sum of Squares". It's source is the weighted sum of squared deviations of group means from grand mean. It's the sum of squares between groups.
C) SST means "Total Sum of Squares''. It's source is total sum of squared deviations from the grand mean. It is a sum of SSE and SSTR.
5/6 divided 1/2
Flip over the second fraction. Changes from 1/2 to 2/1
5/6*2/1
Multiply by the denominator and numerator across
Or you can cross out 6,2 and divide by 2
5/6*2/1= 10/6 Multiplying right away and divide by 2 10/6=5/3
5/6*2/1 ( Crossing out 6 and 2)
6/2=3
2/2=1
5/3
Answer: 5/3
6 sandwiches
because if you divide 3/4 by 1/8 you get 6<span />
