The answer would be -3. if x is -3, then in the equation x2 - x, we would replace both x with -3. So then it would be -3 times 2 minus -3 And if we multiply -3 times 2 we get -6 and -6 minus -3 is -3. I hope this helped you, sweetheart.

The figure above shows the probability density function for the random variable x. What is P(3≤x<7)?
qwelly [4]

The value of the probability P(3≤x<7) is 1

<h3>How to evaluate the probability expression?</h3>

The expression is given as: P(3≤x<7)

This is calculated using:

P(3 ≤ x < 7) = P(3) + P(4) + P(5) + P(6)

Using the figure of the probability density function (see attachment), we have:

P(3 ≤ x < 7) = 0.30 + 0.30 + 0.20 + 0.20

Evaluate

P(3 ≤ x < 7) = 1

Hence, the value of the expression is 1

3) k(a)= a + 4; Find K(0) ; k(2x - 7)
Westkost [7]

Answer: k(0) = 4; k (2x - 7) = 2x -3

Step-by-step explanation:

If k(a) = a + 4

K(0) will be 0 + 4

K(0)= 4

Then, k (2x - 7) = 2x -7 +4

K (2x - 7) = 2x - 3
