Answer:
either 3 or 64
Step-by-step explanation:
unable to process what I already know. 3 or 64
At each step, you determine the quotient term by dividing the highest-degree term of the dividend by the highest degree term of the divisor. When you can't do that anymore, you're done and the remaining dividend is the remainder.
Here, the highest-degree dividend term is x^2 and the highest-degree divisor term is x. Their ratio, x^2/x = x, is the first quotient term. In the usual manner of long division, you subtract the product of this quotient term and the divisor to get the new dividend.
For this problem, the quotient is (x -5) and the remainder is 5. You can write the result as
(x² -10x +30)/(x -5) =
(x -5) +5/(x -5)
Step-by-step explanation:
the expected value is calculated by multiplying each of the possible outcomes by their probability, and then summing up all these results.
tossing a coin 2 times gives us 4 possible different outcomes (all with the same probability of 0.25) :
head - tail
head - head
tail - head
tail - tail
to have exactly one head is 2 out of these 4 possible outcomes, and the probability is 0.5.
everything else is also 2 out of these 4 possible outcomes, and the probability for that is therefore 0.5 too.
the expected value (from your point of view) is
9×0.5 - 15×0.5 = -$3.00
Answer: x = 1.4
Step-by-step explanation:
Simplify:
6-5x+1 = 0
Subtract 1 from both sides:
6 -5x = -1
Subtract 6 from both sides:
-5x = -7
Divide both sides by -5:
x = 1.4
Answer:
X = 3
Step-by-step explanation:
3x = -3x + 15
3x +2x = 15
5x = 15
x = 3
