Michelin Tire Company wishes to set a minimum mileage guarantee on its new MX100 tire. Tests reveal the mean mileage is 67,900 with a standard deviation of 2,050 miles and that the distribution of miles follows the normal probability distribution. Michelin wants to set the minimum guaranteed mileage so that no more than 4 percent of the tires will have to be replaced. What minimum guaranteed mileage should Michelin announce

Answers

Answer:

The minimum guaranteed mileage is [tex]x = 71489.55[/tex]

Step-by-step explanation:

From the question we are told that

The mean is [tex]\mu = 67900[/tex]

The standard deviation is [tex]\sigma = 2050[/tex]

Generally for the probability to be 4% the minimum guaranteed mileage is evaluated as

[tex]P( X \ge x ) =1- P( \frac{X - \mu }{\sigma } < \frac{ x - 67900 }{ 2050} ) = 0.04[/tex]

[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]

[tex]P( X \ge x ) =1- P( Z<z) = 0.04[/tex]

=> [tex]P( X \ge x ) = P( Z<z) = 0.96[/tex]

=> [tex]z = \frac{ x - 67900 }{ 2050}[/tex]

From the z table, the critical value corresponding to 0.96 to the left of the curve is

Using partial quotients, which would be the best choice for the first number to subtract in the division problem 858 +26?

Answers

Answer:

780

Step-by-step explanation:

We want to use partial quotients in the division problem 858 ÷ 26.

In partial quotients method, what we do is to repeatedly subtract from the dividend easy multiples of the divisor.

In this case, the dividend is 858 and the divisor is 26.

Thus, the first easy multiple of the divisor we can use will be 30 because 30 × 26 = 780 yields the closest value to 858.

Therefore, the best choice for first number to subtract is 780

Answer: 780

Step-by-step explanation:

The best choice for the division problem will be 780.

Juanita earns $36 for 3 hours of work. At that rate, how long would she have to work to earn $720?

Answers

Well it would be 7 days. 36 x 3 is 108 720 divided by that is 6 but a remainder so you add one to 6 and it’s 7

Answer:

She has to work for 60hours in order to earn $720.

Step-by-step explanation:

Amount of money earned in 1hour=36÷3

=12$

Total time required=720÷12

=60hours

40:10 = 12 :
Equivalent ratio

Answers

40:10=12:3

Solution:

Since
40 : 10 = 12 : X

Then we know
10/40 = X/12

Multiplying both sides by 12 cancels on the right
12 × (10/40) = (X/12) × 12
12 × (10/40) = X

Then solving for X
X = 12 × (10/40)
X = 3

Therefore
40 : 10 = 12 : 3

A physicist examines 23 sedimentary samples for mercury concentration. The mean mercury concentration for the sample data is 0.036 cc/cubic meter with a standard deviation of 0.012. Determine the 80% confidence interval for the population mean mercury concentration. Assume the population is approximately normal. Step 1 of 2: Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.

Answers

Answer:

The 80% confidence interval is [tex]0.0328 < \mu < 0.0392[/tex]

Step-by-step explanation:

From the question we are told that

The sample size is n = 23

The sample mean is [tex]\= x = 0.036 \ cc/m^3[/tex]

The standard deviation is [tex]\sigma = 0.012[/tex]

From the question we are told the confidence level is 80% , hence the level of significance is

[tex]\alpha = (100 - 80 ) \%[/tex]

=> [tex]\alpha = 0.20[/tex]

Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is

[tex]Z_{\frac{\alpha }{2} } = 1.282[/tex]

Generally the margin of error is mathematically represented as

[tex]E = 1.282 * \frac{0.012 }{\sqrt{23} }[/tex]

=> [tex]E = 0.00321 [/tex]

Generally 80% confidence interval is mathematically represented as

[tex]0.036 -0.00321 < \mu < 0.036 + 0.00321[/tex]

=> [tex]0.0328 < \mu < 0.0392[/tex]
