Mathematics
1 answer:
sukhopar [10]3 years ago
6 0

Answer:

m = -18

Step-by-step explanation:

<u>Step 1:  Combine like terms</u>

-8 = -m + 2m + 10

-8 = m + 10

<u>Step 2:  Subtract 10 from both sides</u>

-8 - 10 = m + 10 - 10

-18 = m

Answer:  m = -18

Sholpan [36]
<h2><u>Answer with explanation:</u></h2>

Let \mu be the population mean.

Null hypothesis : \mu=12

Alternative hypothesis : \mu

Since Alternative hypothesis is left tailed so , the test is a left tailed test.

Given : n=33 > 30 , so we use z-test.

Test statistic : z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

i.e. z=\dfrac{11.2-12}{\dfrac{1.6}{\sqrt{33}}}\approx-2.87

Using z-value table,

P-value for left tailed test =P(z

Since , the p-value (0.0020524) is less than the 0.05 level of significance, it means we reject the null hypothesis.

Therefore, we have enough evidence to support the claim that the mean completion time has decreased under new management.

Find a polynomial with the following zeros. <br><br> HELPPPP ASAPPP
Pavlova-9 [17]

<u>Answer:</u>

x³ - 4x² + 2x + 4 = 0

<u>Here's how I solved this:</u>

<u>You start off by rewriting the zeros into factors:</u>

1 - √3    →    x = 1 - √3    →    (x - 1 - √3)

  2        →    x = 2           →    (x - 2)

1 + √3   →    x = 1 + √3   →    (x - 1 + √3)

<u>Now you want to multiply the factors together:</u>

     (x - 1 - √3) · (x - 2) · (x - 1 + √3)

<em>- Multiply the first two factors together -</em>

                (x - 1 - √3) · (x - 2)

                              ↓

    (x · x - x · 2 - √3 · x + √3 · 2 - x + 2)

 

<em>    - Combine like terms and simplify -</em>

    (x · x - x · 2 - √3 · x + √3 · 2 - x + 2)

                              ↓

          (x² - 3x - √3 · x + 2√3 + 2)

<em>       - Now multiply the third factor -</em>

   (x² - 3x - √3 · x + 2√3 + 2)(x - 1 + √3)

                              ↓

(x² · x + x² · √3 - x² - 3x · x - 3x · √3 + 3x - √3 · xx - √3 · x · √3 +√3 · x + 2 · √3 · x + 2 · √3 · √3 - 2 · √3 + 2x + 2 · √3 - 2)

                              ↓

(x³ + x² · √3 - x² - 3x² - 3x · √3 + 3x - √3 + 3x - √3 * x² - x · 3 + √3 · x + 2 · √3 · x + 2 · 3 - 2 × √3 + 2x + 2 √3 - 2)

<em>    - Combine like terms and simplify -</em>

(x³ + x² · √3 - x² - 3x² - 3x · √3 + 3x - √3 + 3x - √3 * x² - x · 3 + √3 · x + 2 · √3 · x + 2 · 3 - 2 × √3 + 2x + 2 √3 - 2)

                              ↓

                 x³ - 4x² + 2x + 4

--------------------------------------------------------------------------------------------------------------

And there we get our solution: <u>x³ - 4x² + 2x + 4</u>
