In manufacturing processes, it is of interest to know with confidence the proportion of defective parts. Suppose that we want to be reasonably certain that less than 4% of a company's widgets are defective. To test this, we obtain a random sample of 250 widgets from a large batch. Each of the 250 widgets is tested for defects, and 6 are determined to be defective, based upon the manufacturer's standards. Using α = 0.01, is this evidence that less than 4% of the company's widgets are defective? State the hypotheses, list and check the conditions, calculate the test statistic, find the p-value, and make a conclusion in a complete sentence related to the scenario.

What is the solution for the inequality |-5x+2|<7

Answers

i'm just gonna try my best.
it will be -5x+2=7
let's ignore the less than sign, so it will be -5x=7-2
; -5x=5
; x=-1
If the question asks you to graph it, you will graph -1 less than 7 or -1∠7
i'm sorry that i cant find the less than sign

|-5x + 2| < 7
|-5x + 2| < ±7
|-5x + 2| < 7 or |-5x + 2| < -7
-5x + 2 < 7      or -5x + 2 < -7
- 2 - 2 - 2   - 2
-5x < 5    or       -5x < -9
-5 -5 -5 - 5
x < -1 or x < 1⁴/₅

(n-3)(n-5)what's the equivalent

Answers

Lets expand the expression using the FOIL method
FOIL=First,Outer,Inner,Last

We'd start by multiplying the first numbers in each parenthesis by eachother:

(n-3)(n-5)
n*n=n²

Now the outer two values...

(n-3)(n-5)
-5n

The inner two values

(n-3)(n-5)
-3n

And the last two values
(n-3)(n-5)
-3*-5=15

Now just put all of the expressions together...

n²-5n-3n+15
simplify
n²-8n+15

Answer=n²-8n+15

A container at a paper clip factory holds 2.1*10^3 pounds of paper clips. There are 9.6*10^5 paper clips in the container. Find the approximate weight of each paper clip in ounces. (1 pound= 16 ounces) Show Your Work.

Answers

Answer:

The approximate weight of each paper clip is 0.035 ounce.

Step-by-step explanation:

A container at a paper clip factory holds 2.1*10^3 pounds of paper clips.

= $2.1*1000=2100$ pounds

There are 9.6*10^5 paper clips in the container.

= $9.6*100000=960000$

Now we get that 960000 paper clips weigh 2100 pounds.

So, each paper clip will weigh = $(2100)/(960000)$ = 0.0021875 pounds

And 1 pound = 16 ounces

0.0021875 pounds = $16*0.0021875$ = 0.035 ounce

Hence, the approximate weight of each paper clip is 0.035 ounce.

Divide the total weight (2.1 * 10^3 lbs.) by the total quantity of things (9.6 * 10^5) to get the lbs./paperclip.

Then, multiply that number by 16 to get ounces/paperclip.
