The probability that the sample mean would differ from the population mean by less than 655 miles in a sample of 79 tires if the manager is correct is = 0.9805.

<h3>

What is the calculation for the above?</h3>

P (\bar{x} < 655) ≡ P [ |( \bar{x} - μ)/√(σ²/n) | <655/√(6,220,036/ 79)]

= P (| Z | < 3.55)

= P - 3.55 < Z < 3.55) Using the z -score table

= 0.9998 - 0.0193

= 0.9805

Let see if you know long division 3) 461​
WARRIOR [948]

Answer:

461 = dividend

3 = divisor

Explanation:

Step 1:

Start by setting it up with the divisor 3 on the left side and the dividend 461 on the right side like this:

           

   3 ⟌ 4 6 1

Step 2:

The divisor (3) goes into the first digit of the dividend (4), 1 time(s). Therefore, put 1 on top:

       1    

   3 ⟌ 4 6 1

Step 3:

Multiply the divisor by the result in the previous step (3 x 1 = 3) and write that answer below the dividend.

       1    

   3 ⟌ 4 6 1

      3    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (4 - 3 = 1) and write the answer below.

       1    

   3 ⟌ 4 6 1

     - 3    

       1    

Step 5:

Move down the 2nd digit of the dividend (6) like this:

       1    

   3 ⟌ 4 6 1

     - 3    

       1 6  

Step 6:

The divisor (3) goes into the bottom number (16), 5 time(s). Therefore, put 5 on top:

       1 5  

   3 ⟌ 4 6 1

     - 3    

       1 6  

Step 7:

Multiply the divisor by the result in the previous step (3 x 5 = 15) and write that answer at the bottom:

       1 5  

   3 ⟌ 4 6 1

     - 3    

       1 6  

       1 5  

Step 8:

Subtract the result in the previous step from the number written above it. (16 - 15 = 1) and write the answer at the bottom.

       1 5  

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1  

Step 9:

Move down the last digit of the dividend (1) like this:

       1 5  

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1 1

Step 10:

The divisor (3) goes into the bottom number (11), 3 time(s). Therefore put 3 on top:

       1 5 3

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1 1

Step 11:

Multiply the divisor by the result in the previous step (3 x 3 = 9) and write the answer at the bottom:

       1 5 3

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1 1

           9

Step 12:

Subtract the result in the previous step from the number written above it. (11 - 9 = 2) and write the answer at the bottom.

       1 5 3

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1 1

     -     9

           2

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 461 divided by 3 calculated using Long Division is:

153
