First find out how much the 4 volleyball nets are by using 4*28 which would equal to 112. Now subtract 112 from 250 and that leaves you with 138. Then you divide 138 by 7 which will give you about 19.7 which you need to take all decimals out since it isn’t an whole number. The gym teacher can only buy 19 volleyballs.
The velocity of the particle is given by
Since 
and 
, we get
Similarly, the position function is obtained via
We know 
and we're told that 
, so
making the answer A.
Answer:
The expected net winnings for the bet are -$1.0526
Step-by-step explanation:
P(x =+$20) = P(Black outcome) = 18/38
P(x =-$20) = P(red outcome) + P(green outcome)
= 18/38 + 2/38 = 20/38
Hence the probability distribution of x = $20 , P(x) = 18/38
x = -$20, P(x) = 20/38
Expected value of the random variable x is given by ;
miu = Summation [xP(x)] = 20(18/38) - 20( 20/38)
= -$1.0526
hence, the expected net winnings for the bet are -$1.0526
This implies that if a player bet on a very large number of games, the player would on the average lose $1.0526 per single bet
Answer:80 feet
Step-by-step explanation:
Sum of < in a triangle is 180°
<G + <E + <F=180°
90 + 20 + < F = 110
< F = 70°
Using sine rule
sin G\EF = sin F\EG
sin90°\EF = sin70°\75
EF = 75sin90°\sin70°
= 79.81
=80 to the nearest tenth feet.
