How to solve 342x8 the easiest way

The minimum unit cost of the car is $12232.1

Given: cost function C(x)=0.9x² - 414x + 59,366

In order to find the minimum point, take the derivative of the cost function:

dC/dx = 2x - 414          (equate to zero and solve for x)

2x - 414 = 0                

2x = 414

x = 414/2 = 207

Thus, the minimum point is at x =207

The minimum unit cost can be obtained by substituting x = 207 into the cost equation:

C(x) = 0.9x² - 414x + 59,366

C(207) = 0.9(207)² - 414(207) +  59,366

          = 38564.1 - 85698 + 59,366

           = $12232.1

Therefore, the minimum unit cost is $12232.1

Another advantage of using Anova is that it arranges the means so the significant differences can be located and interpreted easily.

The ANOVA test is a type of statistical test used to determine whether there is a statistically significant difference between two or more categorical groups by testing mean differences using variance.

Another important part of the ANOVA is the splitting of the independent variables into two or more groups.

The assumptions for the ANOVA test are the same as those for general parametric tests.

Yusuf remaining observations, considering the statistical measures, are given as follows:

64, 73, 80.

There are four statistical measures used in this problem, which are:

The mode is the observation that appears the most times, hence one of the remaining observations is of 80.

The median is the middle value of the data-set, which is the value of which 50% of the measures are less than and 50% of the measures are greater than.

In this problem, the data-set has an even cardinality, hence the median is the mean of the 4th and of the 5th element, hence, considering the median of 74, the missing element is given as follows:

(x + 75)/2 = 74.

x + 75 = 148

x = 73.

The range is the difference between the largest value and the smallest value in the data-set.

Considering the range of 16 and the highest value of 80, the remaining value is given as follows:

80 - x = 16

x = 80 - 16

Runs scored by Willie Mays is given by the linear equation y = 2x+58.

A linear equation is an algebraic equation which is in the form y=mx+b, where m is said to be the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included.

The variables in the preceding equation are x and y, and it is commonly referred to as a "linear equation of two variables."

Let the runs scored by Roger be x.

According to the question, Willie Mays hit 58 more than double the number of home runs Roger hit.

Runs scored by Willie Mays = 2x+58

Let the runs scored by Willie May be y.

Then, y = 2x+58.

Hence, the runs scored by Willie Mays is given by the linear equation

The measure of each of the missing angles is m<1 = 40°, m<2 = 61°, m<3 = 119°, m<4 = 61°, m<5 = 58°, m<6 = 122°, m<7 = 58°, m<8 = 82° and m<9 = 98°

To solve this problem, we need some angle geometry knowledge:

Since the sum of angles on a straight is 180°. Thus:

m<1 + 82° + 58° = 180°

m<1 = 180° -82° - 58° = 40°

The sum of angles on a triangle is 180°:

m<2 + 58° + 61° = 180°

m<2 = 180° - 58° - 61° = 61°

m<2 + m<3 = 180° (angles on a straight )

61°+ m<3 = 180°

m<3 = 180°-61° = 119°

m<4 = m<2 = 61° (alternate angles)

m<5 + m<4 + 61 = 180° (angles on a straight )

m<5 + 61° + 61 = 180°

m<5 = 180°- 61°-61° = 58°

m<5 + m<6 =  180° (angles on a straight )

58°+ m<6 =  180°

m<6 =  180°-58° = 122°

m<7 =  58°  (alternate angles)

m<1 + m<7 +m<8 = 180° (angles on a triangle )

40+58°+m<8 = 180°

m<8 = 180°-40-58° = 82°

m<8+m<9 = 180° (angles on a straight )

82+m<9 = 180°

m<9 = 180°-82° = 98°

The measure of the missing angles m<1, m<2, m<3, m<4, m<5°, m<6, m<7, m<8 and m<9 are 40°, 61°, 119°, 61°, 58°, 122°, 58°, 82° and 98° respectively

To write our number as a fraction, the order of the steps is:

First, we define our number:

x = 0.1717...

So we start with the step 3.

Now notice that there are two repeating decimals, so we need to multiply both sides by 100 (as many zeros as repeating decimals)

100*x = 10*0.1717... = 17.1717...

This is step 5.

Now we can subtract the original number in both sides so we remove the repeating decimals:

100*x - 0.1717... = 17.1717... - 0.1717...

99*x = 17

These are steps 4 and 2.

Finally, we divide both sides by 99 to get:

x = 17/99

The relative humidity is a measure the average amount of vapor in the air and the random sample of 100 days refers the distribution displays a gap with a potential outlier located between 40% and 45%.

Average:

Given

Relative humidity is a measure, expressed as a percentage, of the amount of water vapor present in air. the following histogram summarizes the relative humidity, at noon, for a random sample of 100 days for a certain city.

Basically, the relative humidity is a variable expressed as a percentage that represents the amount of water vapor present in air. It can be  is used to monitor and predict weather conditions, and it is calculated based on the temperature of the air.

And it is also independent of temperature because a high temperature can have low relative humidity and vice-versa.

While we looking into the given question, there are no observed data values between 45% relative humidity and 55% relative humidity, so there is a gap displayed in the distribution.

Therefore, the value located between 40% and 45% is unusually small when compared with the other data values. And this point are known as outliers that are used to test that it is an outlier would require using the 1.5×IQR rule or using the two standard deviations rule.

When the numerator is always higher than or equal to the denominator, the fraction is said to be an improper fraction.  When a fraction contains a whole number and a proper fraction is said to be a mixed fraction.

Write the given equation with mixed fraction to an improper fraction,

[tex]2\frac{1}{4}+\frac{2}{5}\div \left(\frac{-1}{2}\right)-\frac{1}{4}=\frac{9}{4}+\frac{2}{5}\div \left(\frac{-1}{2}\right)-\frac{1}{4}[/tex]

When we divide a fraction, we convert division into multiplication by turning the fraction upside down. Here, we convert the division sign before (-1/2) into multiplication by changing this fraction upside down as (-2/1).

Therefore,

[tex]2\frac{1}{4}+\frac{2}{5}\div \left(\frac{-1}{2}\right)-\frac{1}{4}=\frac{9}{4}+\left(\frac{2}{5}\times\left(\frac{-2}{1}\right)\right)-\frac{1}{4}[/tex]

Normal Distribution or central tendency is a bell-shaped curve that is produced by many measurements.

The graphical representation of a normal probability distribution, whose underlying standard deviations from the mean form the curved bell shape, is referred to as having a "bell curve." The variability of data dispersion, in a set of provided values around the mean, is measured using a standard deviation. The highest point on the bell curve is the mean, which is the average of all the data points in the data set or sequence.

A bell-shaped normal distribution graph is referred to as a bell curve.

At the peak of the curve, the mean, mode, and median of the collected data are shown.

The standard deviation of the bell curve reveals how pronounced the bell curve is around the mean.
