The probability distribution for a

Tpy6a [65]

Answer:

$P(x \le -3) =0.30$

Step-by-step explanation:

Given

The attached probability distribution of x

Required

Find $P(x \le -3)$

To do this, we consider all values of x less than or equal to-3.

So, we have:

$P(x \le -3) =P(x=-5) + P(x = -3)$

From the table:

$P(x=-5) = 0.17$

$P(x = -3) = 0.13$

So, the equation becomes

$P(x \le -3) =P(x=-5) + P(x = -3)$

$P(x \le -3) =0.17 + 0.13$

$P(x \le -3) =0.30$

How to factor 18a2+6a5-8a3

Zielflug [23.3K]

Answer:

$2a^2(3a^3-4a+9)$

Step-by-step explanation:

You could change the equation to this: $6a^3a^2-8a^1a^2+18a^2$

*This is the exact same as $18a^2+6a^5-8a^3$

You can continue to break this down until you get:

$2*3a^3a^2-2*4a^1a^2+2*9a^2$

*This too = $18a^2+6a^5-8a^3$

With this new equation, you can cancel out the common term: $2a^2$

You come up with my answer.

<em>Hope this helps!!</em>
