226 rounded to the nearesthundred is 200.
We have,
When rounding to the nearesthundred, we look at the digit in the tens place (2 in this case). If it is 5 or greater, we round up the hundreds digit (2) by increasing it by 1.
If it is lessthan 5, we keep the hundreds digit as it is.
Since the tensdigit is 2 (less than 5), we keep the hundredsdigit (2) as it is, and the remaining digits become 0.
Therefore,
226 rounded to the nearesthundred is 200.

Answer:
$400
Step-by-step explanation:
Hi we have to use the Rule of the Three
The price that we paid represents the 80% of the original prize
Hence we have that
$320⇒80% (.8)
$x⇒100%(.1)
As we know we have to multiply diagonally and divide with the one in the corner
So we have (320)*(1 )=320 and then divide
Hence the original price was $400
Answer:
400
Step-by-step explanation:
320/(1-0.2)=Original price
400x0.8=320
Using it's concept, it is found that the variance of the given data-set is of 17.14.
It is the sum of the differences squared betweene each observation and the mean, divided by the number of values.
The mean of the given data-set is given by:
M = (3 + 4 + 5 + 7 + 10 + 12 + 15)/7 = 8
Hence, the variance is given by:
V = [(3-8)² + (4-8)² + (5-8)² + (7-8)²+ (10-8)² + (12-8)² + (15-8)²]/7 = 17.14.

Answer:
(3 + 4 + 5 + 7 + 10 + 12 + 15)/7 = 8
(3^2 + 4^2 + 5^2 + 7^2 + 10^2 + 12^2 + 15^2)/7 - 8^2 = 17.14285714
