Answer:

Given that `x=10`, we can find the value of `a` and `b` by substituting the value of `x` into the given expressions for `a` and `b`.

For `a`, we have: `a = 5x^2/2`. Substituting `x=10`, we get: `a = 5(10)^2/2 = 250`.

For `b`, we have: `b = 2x^2(x-5)/10x`. Substituting `x=10`, we get: `b = 2(10)^2(10-5)/10(10) = 100`.

Therefore, when `x=10`, the value of `a` is 250 and the value of `b` is 100.

What is integration?

Integration is a strategy for combining or joining the parts to get at the total. It is a form of differentiation in reverse where we break down functions into their component elements.

Here, we have

Given: ∫⁹₂ 4dx/(9-8x)

We have to find the simplest form in the logarithmic term.

= ∫⁹₂ 4dx/(9-8x)

We let t = (9-8x)

Now, we differentiate w.r.t x and we get

dt = -8dx

dx = -dt/8

Now we put the value of dx in the given equation and we get

= ∫⁹₂ 4(-dt/8)/t

= ∫⁹₂ -1/2t dt

= -1/2[logt]⁹₂

= -1/2[log9 - log2]

Step-by-step explanation:

=92

Answer: About 9.68

2.9 ^ (x + 10) + 3 - 3 = 92 - 3

2.9 ^ (x + 10) = 89

Next, we'll take the logarithm base 2.9 of both sides:

log2.9 (2.9 ^ (x + 10)) = log2.9 89

x + 10 = log2.9 89

Finally, we'll solve for x:

x = log2.9 89 - 10

To find out how much candy Vanessa should eat each day, we first need to find the total amount of candy in the box. If the box weighs 1/8 of a pound, we can convert this weight to ounces to get a clearer idea of the quantity of candy. There are 16 ounces in a pound, so 1/8 of a pound is equal to 1/8 * 16 = 2 ounces.

Now that we know the total amount of candy, we can divide this by the number of days that Vanessa wants the candy to last to find out how much she should eat each day. If the candy is meant to last 2 days, she should eat 2 ounces / 2 days = 1 ounce of candy per day.

The measure of sides of 7 , 9 , 17 does not form a triangle

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ABC

Now , the measure of sides of the triangle are a , b , c

The value of a = 7

The value of b = 9

The value of c = 17

Now , The sum of the two smallest numbers has to equal a number greater that the largest one

Probability is the part of mathematics that discusses the size of the likelihood of something happening in life. Indeed, there are many events that cannot be ascertained to occur or not occur at a later time. but by knowing the measure of the success or failure of the expected event to occur, people can make better and wiser decisions about what should be done. Probability theory provides methods related to uncertainty and is an integral part of the decision-making process.

The concepts of probability are the basis of samples and the inferences about the population that can be made from a sample. After understanding the concept of probability which is the basis of statistics, we will then be given the theory of random variables and their properties, formation of probability distributions, socialization of various discrete and constant random variable probability distributions, and statistical sampling distributions.

Step-by-step explanation:

The slope of a line can be found using the formula m = [tex]\frac{y_2 -y_1}{x_2 - x_1}[/tex], where m is the slope and [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points on the line.

From the graph we can see that (-2,1) and (0,-3) are two points on the line, so let's sub these values into our formula to find the slope:

m = [tex]\frac{y_2 -y_1}{x_2 - x_1}[/tex]

m = [tex]\frac{1-(-3)}{-2-0}[/tex]=[tex]\frac{4}{-2}[/tex]=-2

The answer is True. Degrees of freedom are a feature of statistics that are used when we are analyzing a sample rather than the population.

The degrees of freedom (df) refers to the number of independent observations in a sample that can be used to make inferences about a population. The concept of degrees of freedom is used in many statistical methods, including t-tests, ANOVA, and regression analysis.

In simple terms, degrees of freedom can be thought of as the number of data points in a sample that are "free" to vary in order to estimate a population parameter. For example, in a sample of two measurements, only one measurement is "free" to vary since the other measurement is used to calculate the mean. Hence, the degrees of freedom would be 1.

It's important to note that when analyzing a population, there are no degrees of freedom since all of the observations are considered independent and can be used to estimate the population parameters. In contrast, when working with a sample, the degrees of freedom are reduced by the number of constraints that are imposed on the sample in order to make inferences about the population.

In summary, the degrees of freedom are a feature of statistics that reflect the number of independent observations in a sample that can be used to make inferences about the population.

Therefore, The answer is True. Degrees of freedom are a feature of statistics that are used when we are analyzing a sample rather than the population.

The equation for the total cost, y, in terms of the number of kites purchased, x, is y = 4x + 8.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that, there is a charge of $4 per kite plus a flat rate of $8 to ship these items to Alaska.

Let x be the number of kites purchased.

Cost for the kites purchased = 4x

Total cost including the shipping charge = 4x + 8

When x = 0, y = $8

When x = 1, y = 4 + 8 = 12

When x = 4, y = 16 + 8 = 24

When x = 7, y = 28 + 8 = 36

When x = 10, y = 40 + 8 = 48

C. Nonsampling error is the error that results from factors outside of the sampling process, such as undercoverage, nonresponse bias, response bias, or data entry errors. Sampling error is the error that results because a sample is being used to estimate information about a population.

Nonsampling error describes problems in data collecting and processing that take place unrelated to the sampling procedure itself. It is brought on by things like inaccurate data collection or measurement, interviewer bias, response bias, undercoverage, or data entry mistakes. Whether a sample or a whole census is employed, nonsampling mistakes can still happen.

On the other hand, sampling error is the error that happens when a sample is used to estimate the characteristics of a population. There will always be some degree of uncertainty when drawing conclusions about the population from sample data because the sample is only a part of the whole population.

The 5th term of the geometric progression is a₅ = 405

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the 5th term of the geometric progression be a₅

Now , the common ratio of the GP is r = 3

And , a₅ = a + 400   be equation (1)

On simplifying the equation , we get

a₅ = ar⁴

Substituting the value of a₅ in the equation , we get

ar⁴ = a + 400

when r = 3

a ( 3 )⁴ = a + 400

81a = a + 400

Subtracting a on both sides of the equation , we get

80a = 400

Divide by 80 on both sides of the equation , we get

a = 5

Now , the 5th term of the GP is a₅ = ar⁴

On simplifying the equation , we get

a₅ = 5 ( 3 )⁴

a₅ = 5 x 81

a₅ = 405

Hence , the 5th term of the GP is 405

The formula for calculating a histogram is (Number of Data Points in Bin) / (Total Number of Data Points).

A histogram is a graphical representation of data which displays how often certain values occur within a set of data. It is a type of bar graph that displays the number of values within each bin or interval. The bins are usually of equal size, and the height of each bar indicates the frequency of the values within the bin. Histograms are used to display the distribution of data, allowing a quick visual representation of the data.= (Number of Data Points in Bin) / (Total Number of Data Points)

suppose we have a set of data with the following values: 4, 5, 6, 7, 8, 9, 10, 11, 12. To construct a histogram, we would first divide the data into bins of equal size. In this case, we could use bins of size 2, so the bins would be 4-5, 6-7, 8-9, and 10-11. We would then count the number of data points in each bin, resulting in the following: 4-5: 2 data points; 6-7: 2 data points; 8-9: 2 data points; 10-11: 2 data points. To calculate the histogram we would take the number of data points in each bin, and divide it by the total number of data points (8). This would give us the following histogram: 4-5: 2/8; 6-7: 2/8; 8-9: 2/8; 10-11: 2/8.
