Sherry claims that the expression 1/x will always be equivalent to a repeating decimal whenever x is an odd number greater than
fomenos

Answer:

The correct options are :

b. 5

e. 25

Step-by-step explanation:

The question is incomplete. The missing part is :

'' Which of these values will prove Sherry's claim is false :

a. 3

b. 5

c. 7

d. 11

e. 25 ''

One way to prove that Sherry's claim is false is finding one odd number greater than 1 that when we replace it in the denominator of the expression \frac{1}{x} the result isn't equivalent to a repeating decimal.

Let's analyze each option :

  • a. 3

3 is an odd number greater than 1 ⇒ If we replace in the expression \frac{1}{x} ⇒

\frac{1}{3}  ≅ 0.3333 (repeating decimal)

The option a. 3 won't prove that Sherry's claim is false.

  • b. 5

5 is an odd number greater than 1 ⇒ If we replace in the expression \frac{1}{x} ⇒

\frac{1}{5}=0.2

The result isn't a repeating decimal.

The option b. 5 will prove that Sherry's claim is false.

  • c. 7

7 is an odd number greater than 1 ⇒ If we replace in the expression \frac{1}{x} ⇒

\frac{1}{7} ≅ 0.1428 (repeating decimal)

The option c. 7 won't prove that Sherry's claim is false.

  • d. 11

11 is an odd number greater than 1 ⇒ If we replace in the expression \frac{1}{x} ⇒

\frac{1}{11} ≅ 0.0909 (repeating decimal)

The option d. 11 won't prove that Sherry's claim is false.

  • e. 25

25 is an odd number greater than 1 ⇒ If we replace in the expression \frac{1}{x} ⇒

\frac{1}{25} ≅ 0.04

The result isn't a repeating decimal

The option e. 25 will prove that Sherry's claim is false.

An appliance manufacturer stockpiles washers and dryers in a large warehouse for shipment to retail stores. Sometimes in handlin
Over [174]

Answer:

This is strong evidence that more than 2% get damaged

Step-by-step explanation:

The company goal is to keep the proportion of damaged machines below 2%

H_o: p = 0.02

H_a: p > 0.02

One day an inspector randomly checks 66 washers and finds that 6 of them have scratches or dents

So, x = 6

n = 66

\widehat{p}=\frac{x}{n}

\widehat{p}=\frac{6}{66}

Formula : z=\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}

z=\frac{\widehat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}

z=\frac{\frac{6}{66}-0.02}{\sqrt{\frac{0.02(1-0.02)}{66}}}

z=4.114

So, the value of test statistic is 4.114

2)  What is the​ P-value of the test​ statistic?

So, p value using calculator =  .00002

p value < α

So, we accept the alternate hypothesis

So, This is strong evidence that more than 2% get damaged

Answer:  f(x) and g(x) are inverses of each other

<u>Step-by-step explanation:</u>

To find the inverse of a function, swap the x's and y's and then solve for "y"

f(x) = 5x + 2

 y  = 5x + 2

Swap:

     x = 5y + 2

<u>    -2 </u>   <u>      - 2 </u>

x - 2 = 5y

<u>÷5     </u> <u>÷5  </u>    

\dfrac{x-2}{5}=y

****************************************************************

g(x)=\dfrac{x-2}{5}\\\\y=\dfrac{x-2}{5}\\\\\text{Swap:}\\x=\dfrac{y-2}{5}\\\\\\(5)x=\dfrac{y-2}{5}(5)\\\\\\5x=y-2\\\\5x+2=y

Andrews [41]

Answer:

8463/32=264 15/32

Step-by-step explanation:

Let's make every fraction improper first.

7 3/4=31/4

5 2/8=42/8

6 1/2=13/2

Simplify 42/8

42/8=21/4

21/4

31/4

13/2=26/4

21/14*31/4*26/4=(21*31*26)/64=16926/64=8463/32
