= -1/8x^5 + 8x^4 + x^2 + 3x - 7

Here you go :)
No, it is not a perfect cube. A perfect cube is a number that is obtained when you cube an integer. For example, 8 (cube of 2), 27 (cube of 3) and 64 (cube of 4). Since -3 cannot be obtained by cubing an integer, it is not a perfect cube.
724.94 I THINK.
787.00+135.46=922.46
922.46-190.05=732.41
732.41-7.47=724.94
Answer:
$3
Step-by-step explanation:
Flipping two fair coins :
Sample space :
{TH, HT, TT, HH}
Atleast one head = 12
If not = - 24
Probability of atleast one head = 3/4
If not ; probability of 2 tails = 1/4
Hence,
X ______12 ______ -24
P(x) ___0.75 ______0.25
Expected value for of gamble E(x) :
Σx * p(x) = (12 * 0.75) + (-24 * 0.25)
E(x) = 9 - 6
E(x) = 3
Expected value of gamble = $3
