Answer:

The sequence is the ratio of 4:8, or 16:32. This is because the sequence needs to be divided into 2 different factors in order for it to match. The sequence is...

add 4, add 8, add 16, continue on.

The formula is...

4 * x = sequence

In this case, <em>x</em> is the increasing factor. I substituted it due to the fact that it's a constantly increasing number, not just a straight-up number we can declare.

The probability can be modeled using the following formula:
$P(X =3)$
wherein X follows the density
$P(X=k)=\frac{1.7^ke^{-1.7}}{k!}$
Now for k = 3 we get:
$P(X=3)=\frac{1.7^3e^{-1.7}}{3!}=0.15$
The probability we are looking for is 0.15.

Solve for x: 3|x − 3| + 2 = 14

vaieri [72.5K]

Answer:

x = 7 x = -1

Step-by-step explanation:

3|x − 3| + 2 = 14

Subtract 2 from each side

3|x − 3| + 2 -2= 14-2

3|x − 3| = 12

Divide by 3

3|x − 3| /3 = 12/3

|x − 3| = 4

Now the absolute value has a positive and negative solution.

x-3 = 4 x-3 = -4

Add 3 to each side

x-3+3 = 4+3 x-3+3 = -4+3

x = 7 x = -1
