The answer is B because first u subtract 3y from both sides and then subtract 15 from both and then divide both sides by -5 and u’ll have y=-5/3x+5 so -5/3 is the slope

A set of data items is normally distributed with a mean of 240 and a standard deviation of 32. Convert 272 to a? z-score
dem82 [27]

Answer:

z-score = 1

Step-by-step explanation:

Given

Mean= μ=240

SD= σ=32

In order to find the z-score of a value, the mean is subtracted from the value and then divided by standard deviation.

The formula for z-score is:

z-score=(x-μ)/σ

Here x is the value whose z-score is to be found.

In the given question, x = 272

So,

z-score=(272-240)/32

=32/32

=1

So , the z-score for 272 is 1..

Answer:

Step-by-step explanation:

x +3 I x⁴ + 0x³ - 6x² + 0x  -28 I x³ - 3x² + 3x - 9

         x⁴ + 3x³

       <u>-       -      </u>

                -3x³ - 6x²

                -3x³ - 9x²

               <u>  +      +     </u>

                        3x² + 0x

                       3x²  + 9x

                       <u> -       -       </u>

                                -9x  -28

                                -9x  - 27

                                <u> +      +    </u>

                                         -1

P(x) =(x +3)* (x³ - 3x² + 3x - 9) + (-1)
