Material for the sides costs $9 per square meter. Let w denote the width of the base. Find a function in the variable w giving the cost C (in dollars) of constructing the box. C(w) = Find the derivative of C. C'(w) = Find the cost (in dollars) of materials for the least expensive such container. (Round your answer to the nearest cent.)

The best prediction of the population in the year 2015 will be 4150

rate of decrease involves The rate of reduction expressing a decrease as a percentage of the initial value.To compute a percentage drop, first determine the difference (decrease) between the two values being compared. Then, divide the reduction by the original number and multiply the result by 100.

Given that an island's peasant population is falling at a rate of 1.7% per year,

A 1.7% decrease means that 98.3% will remain.

as a result, decrease = 0.983/year

A(t) = A(original) multiplied by (0.983)^t

As a result, after 6 years, A(6) = 4600 x (0.983)6 = 4150

As a result, the population in 2009 will be 4150.

The slope of all lines parallel to the line 3x + 7y = -7 is 3/7.

To find the slope of the line 3x + 7y = -7, we can use the slope-intercept formula y = mx + b, where m is the slope.

We can rearrange the equation 3x + 7y = -7 to the slope-intercept form 7y = -3x -7.

We can then divide both sides of the equation by 7 to get the slope, m = -3/7.

Therefore, the slope of all lines parallel to the line 3x + 7y = -7 is 3/7.

The algebraic expression for the given statement total number of hours present in y hours and 45 minutes is equal to ( y + 0.75 ) hours.

As given in the question,

Given statement is equal to :

The total number of hours present in y hours and 45 minutes .

Here we have to convert whole equation into hours we have :

1 hour = 60 minutes

⇒ 1 minute = ( 1 / 60 ) hours

⇒ 45 minutes = ( 45 / 60 ) hours

⇒ 45 minutes = 0.75 hours

Algebraic expression for the given statement in hours  is given by :

y hours and 45 minutes

= y hours + 45 minutes

= y hours + 0.75 hours

= ( y + 0.75 ) hours

Answer:

The conclusion is incorrect because there is exactly one solution to the equation.

Step-by-step explanation:

8x - 12 = 4(12x - 6)

4 x 12x = 48x    4 x -6 = -24

8x - 12 = 48x - 24

Move the terms

8x - 12 - 48x = -24

Move the constant to the right-hand side and change its sign

8x - 48x = -24 + 12

-40x = -24 + 12

-40x = -12

Divide both sides by -40

40x  =  -12

40    =   40

Based on the given polynomial, g(x) = 5x + 17x5, it is a polynomial of the sixth degree because it contains six terms (one constant term, one linear term, and one quintic term). Thus, another name for this polynomial is a sixth-degree polynomial.

Step-by-step explanation:

Because it permits one to assume that the sampling distribution of the mean would typically be normally distributed, the central limit theorem is helpful when examining big data sets. This makes statistical analysis and inference simpler.

Hypothesis :

In statistics, hypothesis testing is used to identify the variance in the group of data that results from genuine variation. Based on the presumptions, the sample data are taken from the population parameter. The hypothesis can be divided into many categories. A hypothesis is described in statistics as a formal statement that explains the relationship between two or more variables belonging to the specified population. It aids the researcher in converting the stated issue into an understandable justification for the study's findings. It provides examples of various experimental designs and guides the investigation of the research procedure.

6% slope means on a run of 100 units, there is just a 6-unit rise. The basic definition of slope is the gradient or incline of the terrain.

A steep slope is an abrupt incline, and a gentle slope is a gradual incline. The river's route flows between the steep, forested hills and their softer counterparts.

This is accomplished by comparing the vertical and horizontal changes, which are frequently stated as rise/run.

Since "percent" or "%" denotes "out of 100" or "per 100," x% can be expressed as

For instance

You can come across a road sign that says "6% Grade" or "Steep Grade" while driving down a highway. The road's grade is essentially its slope, multiplied by 100.

The mean square for error in the ANOVA provides an estimate of the variance of an individual treatment average.

What is a variance?

Variance is the anticipated squared variation of a random variable from its population mean or sample mean in probability theory and statistics. Variance serves as a proxy for dispersion, or the degree to which a set of numbers deviates from their mean.

Here, We have

The mean square for error in the ANOVA provides an estimate

ANOVA = Analysis of VarianceThe correct answer is (B)

The mean square for error (MSE) in the analysis of variance (ANOVA) provides an estimate of the variance of an individual treatment average.

Unlike option C which refers to an individual observation,

option B refers to a group of observations that are classified into a single treatment sample.

The MSE measures (gives an estimate of) the variation within this treatment sample. In this case, the variation is in the average or the mean. This could be average texture, average strength, average penetration, etc.

Permutations and combinations:

permutations and combinations, the various ways in which objects from a set may be selected, generally without replacement, to form subsets. This selection of subsets is called a permutation when the order of selection is a factor, a combination when order is not a factor. By considering the ratio of the number of desired subsets to the number of all possible subsets for many games of chance in the 17th century, the French mathematicians Blaise Pascal and Pierre de Fermat gave impetus to the development of combinatorics and probability theory.

for the slope question :

the slope is the factor of x (2/3 and 3/2) and indicates how steep the line is. and it is expressed as y/x ratio defining how many units y changes, when x changes a certain amount of units.

the bigger the number, the steeper the line.

so, the 4th answer option is correct. g(x) is steeper than f(x).

the lines are not parallel, because they do not have the same slope.

they are not perpendicular, because perpendicular slopes turn the y/x ratio upside down AND flip the sign.
