Given a = 3 and b = - 8 ,
= > 2b² - 4a + 4a²
= > 2( - 8 )² - 4( 3 ) + 4( 3 )²
= > 2( 64 ) - 4( 3 ) + 4( 9 )
= > 128 - 12 + 36
= > 116 + 36
= > 152
hm its just that i dont know so maybe try do smth else
618+5400=6018
6018+(50+2500)=8568
8568-(47+2900)=5621
she has $5,621 in her account
Since $12,000 would be her whole current salary, I would just divide $84,000 by $12,000 because i know 12 can go into 84 evenly.
84,000 ÷ 12,000 = 7
Since it goes in to 84,000 evenly by 7 times, the raise would be 700%.
42.8% players practised more than one time a week
Step-by-step explanation:
Total no of players practising = 7
Players who practice more than once a week= 3
(According to graph player no 1,3 and 5 played more than once in a week)
To find the percentage of the players who practised more than one time a week
The formula used is:
percentage of players practising more than one time a week= ( no of player playing more than once / total no of players ) x 100%
Putting values in the formula
percentage of players playing more than one time a week= %
= %
= 42.8%
So, 42.8% players practised more than one time a week
