What is miles ?

   A mile is a unit of length that is exactly equal to 5280 feet, or 1760 yards, and was standardised as exactly 1609.344 metres by an International agreement in 1959. It is the largest unit commonly used to measure the distance between distant locations.

Here the distance 2 laps = 2.5 miles. Then ,

=> 1 laps = 2.5/2 = 1.25 miles.

Now 3 laps = 3*1.25 = 3.75 miles

Here n laps = 8.75 miles .

=> n* 1.25 = 8.75

=> n = 7 laps .

Now 8 laps = 8*1.25 = 10 miles.

The equation of the line (-4,3) and (2,-4) is y = -7/6x -5/3.

What is equation of line?

The equation of a line is the algebraic representation of a line using cartesian coordinates. The general form of the equation of a straight line is written as y = mx + c. Where m is the gradient of the straight line and c  is the y y-intercept of the straight line.

Given, the points are (-4,3) and (2,-4)

m = -4-3/2+4

m = -7/6

The equation we get

y = -7/6x +b

the point (-4,3), we get

3 = -7/6(-4) +b

3 = 14/3 +b

3-14/3 = b

b = -5/3

Rearranging [1/3, 0.3, 33%, 8/25, 33.6%] in the ascending order of magnitude, we get, [33.6%, (1/3), 33%, (8/25), 0.3].

As per the question statement, we are provided with a set of values       [1/3, 0.3, 33%, 8/25, 33.6%],

And we are required to rearrange the above mentioned set in the ascending order of magnitude.

To answer this question, we will have to convert all the values into fractions with a common denominator, and then arrange the fractions in an ascending order of magnitude of their numerators to obtain our desired answer, that is,

[(1/3) = 0.33333333...]

[(0.3) = (3/10) = (30/100)],

[(33%) = (33/100) = 0.330],

[(8/25) = (32/100) = 0.320]

And, [33.6% = (33.6/100) = 0.336]

Since (0.336 > 0.333 > 0.330 > 0.320 > 0.300),

Therefore, rearranging [1/3, 0.3, 33%, 8/25, 33.6%] in the ascending order of magnitude, we get, [33.6%, (1/3), 33%, (8/25), 0.3]

Answer:

Step-by-step explanation:

The solution to the compound inequality is x > -3. The correct option is the third option x > -3

From the question, we are to solve the given compound inequality

2x - 2 > -8 or -4x ≤ -36

Solving the first inequality

2x - 2 > -8

Add 2 to both sides of the inequality

2x -2 + 2 > -8 + 2

2x > -6

Divide both sides by 2

2x/2 > -6/2

x > -3

Solving the second inequality

-4x ≤ -36

Divide both sides of the inequality

-4x/-4 ≤ -36/-4

x ≥ 9

From the two solutions, we can conclude that x > -3

Hence, the solution is x > -3

If a decision maker wishes to reduce the margin of error associated with a confidence interval estimate for a population mean, she can increase the sample size.

The margin of error refers to the statistic measurement that expresses the level of random sampling error in the outcomes of a survey. If the margin of error of the result is high, the confidence level would be low that a result reflects the census of the entire population. It indicated the difference between the actual and estimated results in a random survey sample. The margin of error is generally used in non-survey contexts to show observational error in reporting measured quantities. In order to minimize the margin of error associated with a confidence interval estimate for a population mean, the researchers can increase the sample size to capture the actual trend of the population more accurately.

The measure of angle B is 40 degrees.

In this question, we have been given angle A and angle B are supplementary angles.

m∠A=(4x−16)°

and m∠B=(x+1)°

since angle A and angle B are supplementary angles,

angle A + angle B = 180°

So we get an equation,

(4x − 16)° + (x + 1)° = 180°

5x - 16 + 1 = 180

5x = 180 + 15

5x = 195

97.5% of American women have shoe sized less than 11.19 according to standard deviation of 1.49 .

What is standard deviation?

It is a measure of how spread out numbers are. It is the square root of the Variance, and the Variance is the average of the squared differences from the Mean.

Main Body:

Here, we want to use the empirical rule to find the percentage of women with shoe sizes less than 11.19

The first thing we shall do here is to find the z-score

Mathematically, that will be calculated using the formula;

z = (x-mean)/SD

z = (11.19-8.21)/1.49

z = 2

We can see that the given value is 2 standard deviation away to the right of mean

So, we want to get the percentage that is between the mean and two standard deviations away from it using the empirical rule

If the mill starts out with 490 tons of grain , then the amount of grain that remains to be sold after milling is 450.8 ton.

In the question ,

it is given that ,

the percent of grain that is lost due to spillage = 3%

the percent of grain that is lost due to mildew = 5%

the total percent of grain lost = grain lost due to spillage + grain lost due to mildew

= 3% + 5%

= 8% of total grain  

given that amount of grain =  490 tons .

amount of grain lost = 8% of 490

= 0.08 * 490

= 39.2 ton ,

So , 39.2 ton of grains is lost .

the amount of grain remain to be sold = 490 - 39.2 = 450.8 ton

We firstly learn about a standard normal random variable which is expressed with a mean and standard deviation.

Since we have to find the probability that a standard normal random variable will be between 0.3 and 3.2 .

So The probability should be

P(0.3<z<3.2)=P(z<3.2)−P(z<0.3)

From the standard value of z

P(0.3<z<3.2)=0.9993−0.6179
