A random number is selected from the interval [6.35, 10]. Find the probability that the number is within a distance of 0.25 from
exis [7]

Let <em>X</em> be a random number selected from the interval. Then the probability density for the random variable <em>X</em> is

f_X(x)=\begin{cases}\dfrac1{10-6.35}=\dfrac1{3.65}\approx0.2740&\text{if }6.35\le x\le 10\\0&\text{otherwise}\end{cases}

8 and 10 are the only even integers that fit the given criterion (6 is more than 0.25 away from 6.35), so that we're looking to compute

P(|<em>X</em> - 8| < 0.25) + P(|<em>X</em> - 10| < 0.25)

… = P(7.75 < <em>X</em> < 8.25) + P(9.75 < <em>X</em> < 10.25)

… = P(7.75 < <em>X</em> < 8.25) + P(9.75 < <em>X</em> < 10)

(since P(<em>X</em> > 10) = 0)

… = 0.2740 (8.25 - 7.75) + 0.2740 (10 - 9.75)

… = 0.2055

Solve: (4p^3) x (-3p)
Firdavs [7]

Answer:

-12p ^4

Step-by-step explanation:

4p^3 * -3p

-3 * 4 = -12

p^3 *p

use the math rule :

a^n * a^m = a^(n+m)

therefore

p^3 * p^1 = p ^(3+1)

= p^4

= <u>-12p ^4</u>
