Answer:

The area (probability) is: 0.6864.

Step-by-step explanation:

According to the statement, we are in front of a normal distribution with the following parameters:

µ (mean) = 0

σ (Standard deviation) = 1.

Then we need to find the area of the shaded region, which is the area between the points -1.21 < z < 0.84.

And the area (probability) is: 0.6864.

Pls help me with this question and explain how you got the answer!!!!!
Luba_88 [7]

Answer:

-87

Step-by-step explanation:

So, first to find <em>x</em> you need to subtract 121 from 180. You do this because both the angle which measures 121 degrees and <em>x</em> lie on the same line, and since a line has an angle measure of 180, you do 180-121 to find <em>x</em>. The same thing can be done for <em>y</em>. Since the angle measure of 34 degrees and y lie on the same line you can calculate 180-34 to get <em>y. </em>So, let's do that.

180-121=x

59=x

180-34=y

146=y

Once you've done that you can easily subtract the two and get your answer.

x-y

substitute the answer for the variables and get

59-146

and then your answer is

-87

Use the long division method to find the result when 9x^3+18x^2+20x+169x 3 +18x 2 +20x+16 is divided by 3x+43x+4.
fenix001 [56]

Given:

Dividend = 9x^3+18x^2+20x+16

Divisor = 3x+4

To find:

The quotient and remainder by using the long division method.

Solution:

Using the long division method, divide the polynomial 9x^3+18x^2+20x+16 by 3x+4 as shown below:

3x+4 |\overline{9x^3+18x^2+20x+16}|3x^2+2x+4\\

         9x^3+12x^2\\\underline{(-)\quad (-)\quad \quad \quad}

             0+6x^2+20x

                   6x^2+8x\\\underline{(-)\quad (-)\quad \quad \quad}

                       0+12x+16  

                             12x+8\\\underline{(-)\quad (-)}

                                     \underline{\quad 0\quad}

Therefore, the quotient is 3x^2+2x+4 and the remainder is 0.
