An athlete has 75% of winning the race if he is not injured. If he is injured, his probability of winning the race is only 15%.
alekssr [168]

Answer:

X = 'is the athlete injured' (X in {0,1})

Y = 'the athlete wins' (Y in {0,1})

P(Y=1|X=0) = 0.75

P(Y=1|X=1) = 0.15

P(Y=1) = 0.51

We are looking for P(X=1) - P(Y=1) = P(Y=1|X=0)*(1-P(X=1)) + P(Y=1|X=1)*P(X=1)

The above equation should provide you with the answer 0.4!

Which product of prime polynomials is equivalent to 3x4 – 81x?
adelina 88 [10]

Given:

The expression is

3x^4-81x

To find:

The product of prime polynomials which is equivalent to the given expression.

Solution:

We have,

3x^4-81x

Taking out the common factors, we get

=3x(x^3-27)

It can be written as

=3x(x^3-3^3)

=3x(x-3)(x^2+3x+3^2)        [\because a^3-b^3=(a-b)(a^2+ab+b^2)]

=3x(x-3)(x^2+3x+3^2)

=3x(x-3)(x^2+3x+9)

Therefore, the correct option is B.

The first step in solving 3.17 t - 2.431 = 5.06 is to divide both sides of the equation by 3.17. TrueFalse
Pavlova-9 [17]

Answer:

False

Step-by-step explanation:

3.17t - 2.431 = 5.06 \\ 3.17t = 5.06 + 2.431 \\ 3.17t = 7.491 \\  \frac{3.17t}{3.17}  =  \frac{7.491}{3.17}  \\ t = 2.363
