$(x^3+x^2+x+2) divide by (x^2-1)$

We use long division to divide

There is no x term in x^2 -1 so we put 0x

x + 1

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

x^2+0x-1 x^3+ x^2 + x+ 2

x^3+0x^2-x

-----------------------------(subtract the bottom from top)

x^2 +2x + 2

x^2 +0x - 1

--------------------------------(subtract the bottom from top)

2x + 3

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

Quotient : x+1

Remainder : 2x+3

Answer:

(A) $H_0$ : μ = 22 ; $H_A$ : μ ≠ 22

(B) Value of the test statistic = -2.69

Step-by-step explanation:

We are given that a local bottler in Hawaii wishes to ensure that an average of 22 ounces of passion fruit juice is used to fill each bottle. He takes a random sample of 65 bottles. The mean weight of the passion fruit juice in the sample is 21.54 ounces. Assume that the population standard deviation is 1.38 ounce.

We have to test the accuracy of the bottling process.

(A) Let, NULL HYPOTHESIS, $H_0$ : $\mu$ = 22 ounces {means that an average of 22 ounces of passion fruit juice is used to fill each bottle}

ALTERNATE HYPOTHESIS, $H_A$ : $\mu \neq$ 22 ounces {means that an average of 22 ounces of passion fruit juice is used to fill each bottle}

The test statistics that will be used here is One-sample z-test;

T.S. = $\frac{\bar X - \mu}{\frac{\sigma}{\sqrt{n} } }$ ~ N(0,1)

where, $\bar X$ = sample mean weight of the passion fruit juice = 21.54 ounces

$\sigma$ = population standard deviation = 1.38 ounces

n = sample of bottles = 65

(B) So, <u>test statistics</u> = $\frac{21.54-22}{\frac{1.38}{\sqrt{65} } }$

= -2.69

Hence, the value of test statistics is -2.69.

Answer: 3.19

Step-by-step explanation:

So to find the average I used a simple but pretty effective method

3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+8/26=3.1923

So the new average is 3.19

Jori has 7 boxes of books,with each box holding the same number of books.he has126 books in all how many books are there per box

bazaltina [42]

Let b be the number of books in a box. Then we can say that the total number of books is equal to the number of boxes times the number of books per box.

7b=126 divide both sides by 7

b=18

So there are 18 books per box.
