To find it, one need to add the biggest possible inaccuracy to each measurement, then multiply to get the biggest volume you can. Also Subtract the largest potential mistake from each measurement, then multiply, to to know the smallest volume that can be produced.

Note that the smallest value in the data set is the minimum. The highest value in the data collection is called the maximum.

Since only one data set is given, the  possible measures can only be around it hence the largest and the smallest value close to it.

The polynomial for the total electricity generated by both geothermal and wind power during 2002-2007 is given by adding the two other ones, we will get:

862x^2 + 93x + 24,621

Here we have two polynomials:

Both of these are in gigawatts, so are in the same units, which means that we can directly add the two polynomials to get a polynomial for the total electricity.

-17x^2 + 165x + 14,481 + 879x^2 - 72x + 10,140

Now we group like terms:

d) = √(-1 - -6)2 + (-4 - 8)2

= √(5)2 + (-12)2

= √169

= 13

Answer:

13

Step-by-step explanation:

We use the distance formula to find the distance between two points

d = sqrt ( (x2-x1)^2 + y2-y1) ^2)

Where ( x1,y1) and ( x2,y2) are the two points

d = sqrt( ( -1 - -6) ^2 + ( -4 - 8) ^2)

   = sqrt ( ( -1+6) ^2 + ( -12) ^2)

  = sqrt( 5^2 + 144)

Only D satisfies both of the inequalities in the system represented by the graph. (Please check the graph attached)

Equations are not necessarily about having a "equal to" sign balanced evenly on both sides. It can occasionally refer to a "not equal to" connection, where one object is more than the other or less than. A connection that compares two numbers or other mathematical expressions in an unequal way is referred to as an inequality in mathematics. These mathematical statements are classified as inequalities in the algebraic language.

Based on the equation, the value of x in 8x^2 + 9 = 313 is 6.2

Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

The quadratic equation is given as

8x^2 + 9 = 313

Subtract 9 from both sides of the quadratic equation

So, we have

8x^2 + 9 - 9 = 313 - 9

Evaluate the difference in the above equation

So, we have

8x^2 = 304

Divide both sides of the quadratic equation by 8

So, we have

8x^2/8 = 304/8

Evaluate the quotient in the above equation

So, we have

x^2 = 38

Take the square root of both sides

x = 6.2

Hence, the value of x in the quadratic equation given as 8x^2 + 9 = 313 is 6.2

Considering the z-test formula, it is found that:

a) Increasing the difference between the sample mean and the original population mean increases the test statistic.

b) Increasing the population standard deviation decreases the test statistic.

c) Increasing the sample size increases the test statistic.

Considering a z-test, the formula for the test statistic is given by the following rule:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which the parameters are defined as follows:

In item a, increasing the difference between the sample mean and the original population mean is increasing the numerator [tex]\overline{x} - \mu[/tex], meaning that the test statistic z will be increased.

In item b, increasing the population standard deviation [tex]\sigma[/tex] means that the denominator of the formula will be increasing, hence the test statistic will be decreased.

In item c, increasing the sample size n means that the denominator will be decreased, as the denominator is a fraction which is inverse proportional to the sample size, hence the test statistic z will be increased.

The probability that a group consisting of 2 Democrats and 2 Republicans will be chosen for early release will be 5/11.

It should be noted that probability simply means the likelihood that a particular event will happen.

In this case, there are there are 5 Democrats and 6 Republicans and rour of these people will be randomly chosen for early release.

The probability that a group consisting of 2 Democrats and 2 Republicans will be chosen for early release will be:

Number of Democrats = 5

Number of Republicans = 6

Total number = 5 + 6 = 11

This will be illustrated through the combination formula:

The points at which a graph changes direction (from increasing to decreasing or decreasing to increasing) are called turning point.

A turning point is when the derivative's sign changes. A relative maximum or relative minimum might mark a turning point (also known as local minimum and maximum). A turning point is a stationary point if the function is differentiable, however not all stationary points are turning points.

A turning point is a location on a graph where the trend shifts from rising to dropping or from decreasing to increasing (falling to rising). To determine the point, identify the leading term of the polynomial function if the function were enlarged. A polynomial of degree n will have at most n1 turning points. Next, determine the polynomial function's degree.

Step 1 of the solution:

Step 2 of the solution:

This function passes through (0, 0) and slope = 1 or -1.

Step 3 of the solution:

After transformation vertex (0, 0) becomes (-2, 3) and a point through which this function passes through is (-1, 0)

Step 4, let's find the slope of the absolute value funtion, this way:

Step 5: Interpretation

Since slope of the absolute value function is less than the parent function: -3 < -1

Therefore, the parent function will be dilated by a scale factor other than 1.

The length of each side of the octagon would be 8.23 inches.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

We are aware that one side of the square is 20 inches long and that one side is made up of the length of the octagon added. We also know that two sides of a right triangle have smaller angles inside that are 45 degrees, making those two sides equal to one another. Therefore, we add the two sides of the right angle triangle to the side of the octagon, which equals 20 inches, to determine the value of x, which is designated as the side of the octagon.

Since a side of the square is 20 inches

Here, y is the two equal sides of the right-angle triangle

So y + x + y = 20

Using Pythagoras's theorem for the right angle triangle

y² + y² = x²

2y² = x²

y² = (x²)/2

y = x /√2

So substitute the value of y = x /√2 in the equation

x /√2 + x + x /√2 = 20

2x /√2 + x = 20

2x /√2 + x√2 /√2 = 20

x[2/√2 + √2 /√2] = 20

x[(2 + √2) /√2] = 20

x(2 + √2) = 20√2

x = 20√2/(2 + √2)

x = 28.2843/3.4142 = 8.2343

Round to the nearest hundredth of an inch

x = 8.23

Therefore, the length of each side of the octagon would be 8.23 inches.

The probability of getting 12 p events is 0.0139

The expected value, or mean, of a binomial distribution is calculated by multiplying the number of trials (n) by the probability of successes (p), or n x p.

The binomial distribution formula is calculated as:

[tex]P(x:n,p) = ^nC_x * p^x*(1-p)^ {n-x}[/tex]

where:

n is the number of trials (occurrences)

X is the number of successful trials

p is probability of success in a single trial

is the combination of n and x. A combination is the number of ways to choose a sample of x elements from a set of n distinct objects where order does not matter and replacements are not allowed.

So, we have given that N = 15, P = 0.50 , and x = 12

So,

[tex]^{15}C_1_2 * (0.50)^{12}*(1-0.50)^ {15-12}\\^{15}C_1_2 * 0.50^{12}*(0.50)^ {3}\\[/tex]
