After analyzing this data set, francine calculates a value of 20. 73 g. Which of these characteristics has been calculated? mean median mode range.

Answer:

triangle

Step-by-step explanation:

a quadrilateral is a four-sided figure, but a triangle is three-sided, so a triangle isn't a quadrilateral.

The standard deviation of the data represented is 4.

The standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

From the question, We were given the terms,

4 8 12 24

The number of terms=5

We will obtain the mean value and then calculate the square of the difference between each term and the mean.

The mean=Sum of terms/Number of terms

Mean=(4+8+10+12+16)/5

=50/5

=10

Now, the difference between terms and the mean is as follows:

4-10= -6

8-10= -2

10-10=0

12-10=2

16-10=6

Squaring the obtained values and adding them,

=36+4+4+36

=80

The standard deviation of the terms=

Square root of the sum of squares of values divided by the number of terms

[tex]\sqrt{80/5}[/tex]

[tex]\sqrt{16}[/tex]

4

Hence the standard deviation is 4.

When the start fraction is 1 and the end fraction is 27, the value is a=-11/3.

A fraction is a part of a whole or, more broadly, any number of equal parts. In ordinary English, a fraction describes the number of components of a specific size and consists of a numerator displayed above a line (or before a slash like 12) and a non-zero denominator displayed below (or after) that line.

In addition to common fractions, numerators and denominators are used in rare fractions such as compound fractions, complex fractions, and mixed numerals.

Positive common fractions have natural integers as their numerator and denominator.

The slope of the line in the simplest form is 1 / 2.

The slope of a line is the change in the dependent variable with respect to the change in the independent variable.

The slope is rise over run.

The slope of the line can be found as follows:

m = slope = y₂ - y₁ / x₂ - x₁

Therefore, using (7, 0) and (3, -2)

Hence,

x₁ = 7

x₂ = 3

y₁ = 0

y₂ = -2

There is the not sufficient evidence that the average small business loan is different that the amount stated in the  investment blog.

What is standard deviation?

The standard deviation in statistics is a measurement of how much a group of values can vary or be dispersed. A low standard deviation suggests that values are often close to the set's mean, whereas a large standard deviation suggests that values are dispersed over a wider range.

Here we have given that,

Claim: To check whether the average small business loan is different that the amount stated in the  investment blog.

The hypothesis is,

H0: μ= 20 thousand dollars  Versus  H0: μ ≠ 20 thousand dollars

We have given that,

n= Number of observation = 25

x bar  = sample mean =18.5

S= sample standard deviation =5

Here, population standard deviation is unknown, we use the one sample t test.

t - statistics = (x bar - μ) / (s / √n)

                   = (18.5 - 20) / (5 / √25)

                   = -1.342

we get,

the Test statistic is -1.342

Now we find the P-value

α = level of significance = 0.05

Degrees of freedom = n - 1 = 25 - 1 = 24

This is two tailed test as our interest is to show the population mean is equal or not equal to zero.

Now, we can find the P-value

P-value = 0.1922     Using EXCEL = TDIST( | t-statistics | = 1.342 , D.F=24, tail=2)

Hence, There is the not sufficient evidence that the average small business loan is different that the amount stated in the investment blog.

The ratio of the depth of the liquid to the depth of the cup is 4/5.

Geometry and Ratio

The formula for the volume of a cone is:

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]

where r is the radius of the base of the cone and h is the height of the cone.

When the conical cup is filled with water, there will be a difference in the radius of the water and the cup and a difference in the height of the water and the height of the cup (can be seen in the picture).

From the difference in radius and height of the water with the conical cup, a ratio can be made of similarity rule of triangle (see picture).

If the radius of water is [tex]r_{1}[/tex] and the height of water is [tex]h_{1}[/tex], radius of cup is [tex]r_{2}[/tex] and the height of cup is [tex]h_{2}[/tex], so:

[tex]r_{1}[/tex] with [tex]r_{2}[/tex] and  [tex]h_{1}[/tex] with  [tex]h_{2}[/tex] have the same certain ratio. Let's assume the ratio is x, then it can be written:

The division algorithm for integers states that given any two integers a and b, with b > 0, we can find integers q and r such that 0 < r < b and

a = bq + r.

According to the given question:

q + r  is divisible by 11 if and only if N is divisible by 11. This is because their difference is divisible by 11:

N − (q + r) = 100q + r − q − r = 99q = 11 x (9 x q) . So what you're asking is how many 5 -digit numbers are divisible by 11.

The first such number is  10010 = 910 x 11 because  ⌈10000/11⌉=910 .

What is a Central Angle?

The central angle is the angle that a circle's arc occupies in its centre. The arms of the central angle are formed by the radius vectors. In other words, it's an angle whose vertex is the centre of a circle and whose arms, which have the circle's two radii as their arms, cross at two separate positions. These two points make an arc when they are combined. The angle that this arc at the circle's centre subtends is known as the central angle.

According to the central angle theorem, we state that:

Theorem: An arc's angle at the circle's centre is twice as large as its angle at any other point along the circle's circumference.

While the midpoints of a sides of a rectangle having area $a$ are united to produce a triangle with size $m$, the area of a new triangle equals $frac14$ the area of a original triangle.

A "area" is the size or length of an a double surface, which is frequently measured in square units. It is employed to describe a shape's or object's size, such as the length, width, or height of a side, a bit of land, or even a geometrical figure. By dividing a form's length by its breadth, the area of the form may be calculated. For instance, a rectangle with dimensions of 5 units in length and 3 units in width has a surface area of 15 square units. The area of a circle is calculated using the formula r2, wherein r is the ring's radius. A fundamental geometric concept known as "area" has several applications in the sectors of construction, real estate, and horticulture.

Assume that the original triangle has sides that are s1, s2, and s3. The triangle's area when the side's midpoints are united is [m=frac s 1s 2s 3 16].

A system of linear equations is a collection of two or more linear equations that have two or more variables each. All of these equations are considered at once.

Finding a numerical value for each variable in the system that will simultaneously satisfy all of the system's equations is necessary to identify the one and only solution to a system of linear equations. There could be an unlimited number of solutions for some linear systems, whereas others might not have any. There must be at least as many equations as there are variables for a linear system to have a singular solution. However, this does not ensure an original answer. There is always one answer to a set of equations that makes sense. A consistent system, like the one we just examined, is said to be an independent system if it only has one solution. The two lines cross at one location in the plane and have different slopes. If the equations' slopes and y-intercepts match, the system is said to be consistent and considered a dependent system.
