Sqrt(-108) - sqrt(-3) produces two imaginary terms: -i*sqrt( 36*3) -i*sqrt( 3).
Let's simplify that:
-i [ 6*sqrt(3) - 1*sqrt(3) ] = -i * 5* sqrt( 3) (answer)
Answer:
7.5
Step-by-step explanation:
The probability of winning = 3 out of 20 ;
P(winning) = 3/20
Predicted Number of winnings if game is played 50 times ;
P(winning) * number of games played
(3 /20) * 50
0.15 * 50
= 7.5
Predicted Number of winnings = 7.5
There are 4 quarts in 1 gallon. You would multiply 4 qts x 9 gallons for a total of 36 quarts. He used 10 quarts and 3 gallons (12 quarts) leaving 14 quarts. There are 2 pints in every quart so you would multiply 2 x 14 for 28 quarts. I hope that helped!!!
Answer:
The component on the left of original one would be
30 x cos45 =30 x sqrt2/2 =~21.21
The component on the right of original one would also be
30 x cos45 =30 x sqrt2/2 =~21.21
