Answer:
-40
Step-by-step explanation:
f(a) = a³ - a² + a - 1
f(-3) = (-3)³ - (-3)² + (-3) - 1
f(-3) = (-27) - (9) + (-3) -1
f(-3) = -27 - 9 -3 - 1
f(-3) = -40
Answer:A)0.27
B)0.78
Step-by-step explanation:
This is the probability of picking 2balls of same color.
P(RR)+Pr(WW)+Pr(BB)
3/10×2/9+4/10× 3/10+3/10 ×2/9=6/90+12/90+6/90=
24/90=4/15=0.27
B)if the first ball is not returned, then there are 9 balls left.
Then probability of same color will be
PrB+PrW+PrR
2/9+3/9+2/9=
7/9=0.78
I think its 2 (not sure though just a guess)
Answer:
the answer is 6
Step-by-step explanation:
<span>P = 2l + 2w
The given values fit the given formula</span>
The given values are 134
Let L = 5 - w
Solution:
P = 2l + 2w
134 = 2(5-w) + 2w 134 = 10-2w + 2w 134 – 10 = 4w 124 = 4w
31 = w
<span>26 = l</span>
