Answer:

We can break this down:

The student has a one out of five chance of getting a correct answer, and a four out of five chance of an incorrect answer. We can express the students odds of getting one incorrect answer as 4/5. In order to get the odds of two wrong answers, we need to multiply this answer again by the odds of choosing a wrong answer. Therefore:

The odds of one wrong answer = 4/5

The odds of two wrong answers = (4/5) * (4/5) = 16/25 chance of getting both of the questions wrong.

Step-by-step explanation:

Let P be a non zero polynomial such that P(1+x)=P(1−x) for all real x, and P(1)=0. Let m be the largest integer such that (x−1)

marin [14]

Answer:

m = 0, P(3)/2, P(4)/6, P(5)/12 ..........

Step-by-step explanation:

For non zero polynomial, that is all real x as follows:

x = 1, 2, 3, 4 ............

Using, P(1 + x) = P(1 - x)

For x = 1: P(2) = P(0) = 1

For x = 2: P(3) = P(-1) = 2

Hence, P(x)/m(x - 1) can be solved as follows:

When = 1

P(2)/0 = 1

∴ m = 0

When x = 2

P(3)/m = 2

∴ m = P(3)/2

When x = 3

P(4)/2m = 3

∴ m = P(4)/6

When x = 4

P(5)/3m = 4

∴ m = P(5)/12

Hence, m = 0, P(3)/2, P(4)/6, P(5)/12......

HELP A cube has a volume of 512 in^3. whats the side length

maxonik [38]

Answer:

8 in

Step-by-step explanation:

volume of a cube is found by multiplying three sides or finding the third power of a side

$V=s^{3}$ , where V is volume and s is side length

we are given that V = 512, so

$512=s^{3}$

$s=\sqrt[3]{512}$

s=8

Plzzzz help due tomorrow

Artyom0805 [142]

Answer:

2.a)31°

b)135°

3.a)72°

Step-by-step explanation:

2a) Angles in a straight line add up to 180°

180-62=118°

since in an isosceles triangle base angles are equal 62÷2=31°

b)sum of interior angles=180(n-2)

180(8-2)=1080°

each angle is 1080÷8=135°

3.a) Exterior angle=360/n

=360÷5=72° each
