The study of statistics rests on two major​ concepts probability which  is the branch of mathematics that deals with the likelihood of events occurring and Data Analysis is the process of examining and interpreting data in order to gain insights and make better decisions

Probability theory is based on the idea that, given enough data, the frequency of an event can be predicted and allows for the formulation of mathematical models that can quantify the likelihood of particular outcomes. Probability is the foundation of statistics and helps to explain the behavior of chance events.It involves the collection, organization, and analysis of data from a variety of sources, such as survey responses, observations, experiments, or existing databases.

Data analysis is used to identify patterns and relationships in data, draw conclusions, and make decisions. It is an important part of statistics, as it helps to uncover insights that would otherwise remain hidden. Data analysis tools, such as statistical models, can be used to gain greater insight into the data.

Answer and Explanation:

Congruent line segments have the same length.

Therefore, to construct a segment congruent to EF that has an endpoint on point G, we simply have to draw a line that is the same length as EF that ends on G.

See the attached image for a sample answer.

A 95% confidence interval for the mean is (3193, 2607).

Confidence interval in simple words is the range of values that the specific parameter lies within.

Confidence interval for mean is found by the formula,

CI = Х ± t [tex]\frac{s}{\sqrt{n} }[/tex]

where X is sample mean, s is the standard deviation and n is the sample size.

Sample mean = 2900

s = 1300

n = 55

Degree of freedom = n - 1 = 54

t value of degree of freedom 54 with the probability of exceeding the critical value as 1 - 95% = 5% = 0.05 is 1.674.

CI = 2900 ± (1.674)[tex]\frac{1300}{\sqrt{55} }[/tex]

   = 2900 ± 293.44

   = (3193.44, 2606.56)

   = (3193, 2607)

Hence the confidence interval is (3193, 2607).

Answer:

no solution

Step-by-step explanation:

Since you are using substitution, you will plug in one of the variables using one of the equations.

y=x+4

x-y=8

put the y from above into the y below

x-(x+4)=8

Now, solve the equation

x-x-4=8

Put x's together

-4=8

-4 does not equal 8, so this system of equations has no solution

The point estimate from a confidence interval can be found by taking the midpoint of the interval.

The formula for the point estimate is (lower bound + upper bound) / 2. For example, the 95% confidence interval for a sample mean of 25 is (23, 27). The point estimate for this sample mean is (23 + 27) / 2 = 25. This point estimate is the best estimate of the true population mean.

In essence, the point estimate is the best guess of the population mean given the data. It is calculated by taking the midpoint of the confidence interval, which is the range of values that is believed to contain the population mean with a certain degree of confidence. The point estimate is usually the most reliable estimate and is used to make decisions in statistical analysis.

The graph of an absolue value function is V shaped, symmetric about y-axis or any line parallel to y-axis.

We know that an absolute value of any number describes the distance from zero of that a number is on the number line, without considering its sign (negative / positive number).

Consider an absolute value function f(x)

f(x) = |x|

This means, |x| = x              .......(if x ≥ 0)

            and |x| = -x              .......(if x < 0)

We know that the graph of the absolute value function is V shaped and symmetric about the y -axis or any line parallel to y-axis.

The graph makes a right angle at the origin.

The probability of the spinner is P(not yellow) = 37.5%.

What is the probability?

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

If the spinner is spun once, the probability of not landing on yellow (sections 2 and 3) is equal to the probability of landing on purple (sections 1 and 8), blue (sections 4, 5, and 6), or orange (section 7).

The total probability of these sections is 1- (2/8) = 1-(1/4) = 3/4.

So P(not yellow) = 3/4 = 37.5%.

If tangent of x degrees equals four-thirds, and measures of triangle is 10. 5 units, and NM measures 2b units then the value of b is equals to seven. So, last option is correct, b = 7 here.

Right angled triangle : A triangle is defined as a regular polygon, with three sides and the sum of any two sides is always greater than the third side. Right angled triangle is one type of triangle. When the angle between a pair of sides is equal to 90 degrees it is called a right-angle triangle. See in above figure ∆LMN is a right angled triangle with m∠LMN = 90° . Also, we have m∠MLN = x° so, m∠LNM = 180° - 90° - x° = 90° - x° ( Since, sum of interior angles of triangle = 180°)

Length of side LM = 10.5

length of side, NM = 2b

tangent of x, tan x = 4/3

We have to determine the value of b. For considering angle x° as centre point then

base of triangle = LM = 10.5

As we know Tangent of any angle is equals to ratio of perpendicular/base.

so, tan x = 4/3 = LM/NM

=> 4/3 = 2b / 10.5

=> 4× 10.5 = 2b × 3

=> b = 42.0/6

=> b = 7

So, the required value is 7.

They are both quadrilaterals and they both have equal and parallel opposite sides.

Rectangles and parallelograms both have four sides, and thus are quadrilaterals.

Quadrilaterals

The definition of a quadrilateral is a 2-D shape with 4 sides and 4 angles. Rectangles and parallelograms both fall under this category. So, they both have all the attributes listed in the definition.

This means 3 shared attributes of rectangles and parallelograms are:

Opposite Sides

Rectangles and parallelograms also have unique relationships between opposite sides. Remember that opposite sides are directly across from each other and not adjacent. In both shapes, opposite sides are parallel. This means that if the sides were to continue forever, they would never intersect. Also, opposite sides are equal. By this, I mean that the lengths of opposite sides are equal. Another way to say this is that opposite sides are congruent.

The quotient is 2x^2 + 4x + 5.

The given polynomial is 2x^3 - 3x -10.

As we can see that the given polynomial is a three-degree polynomial but the second degree term is missing, so we can write the polynomial as 2x^3 + 0x^2 - 3x -10.

The divisor is (x-2).

First we choose a term to multiply with the first term of the divisor such that we get the first term of the polynomial:

(x) (2x^2) = 2x^3

Thus, we multiply the divisor (x-2) by 2x^2 which gives 2x^3 - 4x^2

Now we subtract this from the polynomial which gives 4x^2 -3x -10.

Repeating the same we multiply the divisor by 4x which gives 4x^2 - 8x. Subtracting the same from 4x^2 -3x -10, we get 5x - 10.

Now we multiply the divisor with 5 to get 5x - 10. Subtracting it from the remaining polynomial 5x -10 leaves the remainder 0.

Thus, we get the quotient as  2x^2 + 4x +5.

Answer: the equation of the line that is perpendicular to y = -2x + 5 and passes through the point (-4, 2) is y = (1/2)x + 5.

Step-by-step explanation:

The slope of the line that is perpendicular to y = -2x + 5 is the negative reciprocal of the slope of y = -2x + 5, which is -2. The negative reciprocal of -2 is 1/2.

To find the equation of the line that is perpendicular to y = -2x + 5 and passes through the point (-4, 2), we can use the Point-Slope Form: y - y₁ = m(x - X1)

y - 2 = (1/2)(x + 4)

Simplifying, we get:

y = (1/2)x + 5

So the equation of the line that is perpendicular to y = -2x + 5 and passes through the point (-4, 2) is y = (1/2)x + 5.
