Determine the standard deviation (SD)
The standard deviation of a binomial distribution is calculated as thus:
Substitute values for n and p
Convert to decimals
--- <em>approximated</em>
<em>Hence, the calculated standard deviation is approximately 8.4932</em>
Answer:
identity :- ( a + b ) ( a - b ) = a² - b ²
Answer :- 89,694
Step-by-step explanation:
Given : 294 × 306
split 294 × 306
294 × 306 = ( 300 - 6 ) × ( 300 + 6 )
Using Identity, ( a + b ) ( a - b ) = a² - b ² :
= ( 300 )² - ( 6 )²
= 90000 - 36
= 89,964
Hence, 294 × 306 = 89,694
