Judy's total score is 3.

The difference between the lowest and highest score is -12.

The combined total of the scores from round 1 is -5.

The mathematical operations that would be used to solve this question are addition and subtraction. Addition is the process used to determine the sum of two or more number. The sign used to represent addition is +. Subtraction is the process used to determine the difference between two or more numbers. The sign used to represent subtraction is -.

Judy's total score is the sum of the score in round one and round one.

Judy's total score = -3 + 6 = 3

For negative numbers, the further the number is from 0, the smaller the number. For example, -10 is smaller than -5. For positive numbers, the closer the number is to zero, the smaller the number. For example,1 is smaller than 5.

Looking at the table, the smallest number is -6 and the largest number is 6

The difference : -6 - 6 = -12

The total scores from round 1 =  1 -6 +1 +2 -3 = -5

This article discusses the idea of limit in general. See Limit of a sequence and Limit of a function for additional detailed situations. See Mathematics (limit) for further usage.

Limits are crucial to calculus and mathematical analysis because they are needed to determine continuity, derivatives, and integrals. Limits are the value that a function (or sequence) approaches when the input (or index) approaches some value.

In addition to being closely connected to limit and direct limit in category theory, the idea of a limit of a sequence is further expanded to include the idea of a limit of a topological net.

Based on the definition of complementary angles, the measures are:

m<q = 32°

m<r = 58°

Tow angels are complementary if both angles give a sum of 90 degrees.

The sum of angle q and angle r would give 90 degrees because they are complementary angles. Therefore, we would have the following:

m<r = ?

m<q = m<r - 26

Plug in the values

m<r - 26 + m<r = 90

2(m<r) - 26 = 90

2(m<r) = 90 + 26

2(m<r) = 116

2(m<r)/2 = 116/2

m<r = 58°

m<q = m<r - 26 = 58 - 26

m<q = 32°

Therefore, based on the definition of complementary angles, the measures are:

m<q = 32°

m<r = 58°

The length of the altitude of the equilateral triangle ABC is [tex]\frac{13\sqrt{3} }{2}[/tex].

Equilateral Triangle is defined as the triangle with all the sides equal and all the angles = 60 deg.

Altitude of a Triangle can be defined as the perpendicular drawn from the vertex of a triangle to the opposite side.

According to the question

In the figure given below

In ΔADC

Since ΔADC is a right angle triangle we can apply Pythagoras Theorem.

Let the sides of the equilateral triangle be "a". and "h" be the altitude.

Since the altitude is of equilateral triangle it divides the base i.e. DC=a/2

[tex](AC)^{2} =(AD)^{2}+(DC)^{2}[/tex]

[tex]a^{2} =h^{2}+(\frac{a}{2})^{2}\\ \\ h^{2}=\frac{4a^{2}-a^{2}}{4} \\ \\ h=\sqrt{3} *\frac{1}{2} *a[/tex]

Substituting the value of a=13 we get

Altitude [tex]h=\frac{13\sqrt{3} }{2}[/tex]

What is mathematical expression?

A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

3x +y+2z=-10  equation 1

x+5y+2z=-12  equation 2

-2x+3y=-1       equation 3

Subtracting equation 1 to equation 2, we get

3x +y+2z - (x+5y+2z)=-10 - (-12)

3x +y+2z - x -5y -2z = -10 + 12

2x - 4y = 2   equation 4

Adding equation 4 to equation 3, we get

2x - 4y -2x+3y = 2 - 1

- y = 1

y = -1

Putting the value of y in equation 4, we get

2x - 4y = 2

2x - 4(-1) = 2

In linear equation ,Jerry's expression is correct.

What in mathematics is a linear equation?

As you can see, starting with border 1, we have 6 daises (white squares) surrounded by 10 tulips (colored squares). Through Jerry's expression we expected:

= 8(b − 1) + 10

= 8(1 − 1) + 10

= 0 + 10

= 10 tulips.

When considering border 2, we expect:

= 8(b − 1) + 10

= 8(2 − 1) + 10

= 8 + 10

= 18 tulips.

Indeed, we have the 10 tulips from border 1 and 8 additional tulips, for a total of 18 tulips.

Then, consider border 3, we expect:

= 8(b − 1) + 10

= 8(3 − 1) + 10

= 16 + 10

= 26 tulips.

Again, this is correct: we have the 10 tulips used in border 1 plus other 16 tulips, for a total of 26.

Therefore, Jerry's expression is correct.

Based on the definition of vertical angles, m<A = 36°.

Two angles that are vertically opposite to each other are called vertical angles, and they have congruent angle measures. That is, vertical angles are equal.

Angles A and B are vertical angles, then, they are equal to each other.

m<A = (7x + 22)°

m<B = (8x + 20)°

m<A = m<B

Substitute

7x + 22 = 8x + 20

7x - 8x = -22 + 20

-x = -2

x = 2

m<A = 7x + 22

Plug in the value of x

m<A = 7(2) + 22

m<A = 14 + 22

By assuming that one of the two integers is even we will reach an absurd, and in that way, prove the given statement.

Remember that an odd integer number is written as:

A = (2n + 1)

While an even number would be written as:

B = 2n

Where n is a random integer.

Then if x times y is an odd integer we can write:

x*y = (2n + 1)

Where n, m ∈ Z.

Where Z is the set of integer numbers.

Now, let's do find an absurd. Let's suppose that one of the two numbers is even, then we can write:

x = 2m

And y can be even or odd, it does not matter, but it is an integer.

Replacing that we get:

x*y = (2m)*y

We can rewrite that as:

(2m)*y = 2*(m*y)

We know that integer numbers are closed under the product, and here m and y are integers, then m*y is also an integer.

Thus, 2*(m*y) is 2 times an integer, then that is an even number, which is absurd because we know that it should be odd. So, if at least one of the two integers is even, then the product will also be even.

Then if the product is odd, neither of the integers can be even, then we conclude that both of the integers are odd integers.

The standard error on the mean of these numbers is 1.08

For given question,

suppose your group measures the following three numbers in some experiment: 12.4,7.8,10.2

Mean of these numbers is:

[tex]\bar x=\frac{ 12.4+7.8+10.2}{3}\\\\ \bar x=10.13[/tex]

So the standard deviation would be,

[tex]\sigma=\sqrt{\frac{(12.4-10.13)^2+(7.8-10.13)^2+(10.2-10.13)^2}{3} }\\\\\sigma=1.88[/tex]

Now we find  the standard error on the mean of these numbers.

[tex]\sigma_M=\frac{\sigma}{\sqrt{N} }[/tex]

where, [tex]\sigma_M[/tex] = standard error of the mean

σ = the standard deviation of the original distribution

N = the sample size

Similarly, Q1 is obtained as the median of the lower half as (7+1)/2th = 4th observation i.e 60.

Similarly, Q3 is obtained for the upper half as 79 (4th upper half)

IQR (Interquartile Range) = Q3 - Q1 = 79 - 60 = 19

The interquartile range is a gauge for where a data set's "middle fifty" lies. An interquartile range (IQR) measures where most of the values lay, whereas a range measures where a set's start and finish are. For this reason, it is preferable when reporting things like academic performance or SAT scores over many other measures of spread.

The interquartile range IQR is 19

In ascending order we have: 48,51,57,60,63,65,69,71,72,73,75,79,85,88,97

Also, we get sample size (n) = 15 (odd)

So, Median = Q2 = (n+1)/2th observation

Median = (15+1)/2th term = 8th observation

Median = Q2 = 71

Herein we must find what integers are within the interval of a simultaneous linear inequality, whose definition is shown below:

4 < 4 · x + 5 < 175        

Which is equivalent to the following two inequalities:

4 · x + 5 > 4                     (2)

4 · x + 5 < 175                  (3)

By (2):

4 · x + 5 > 4

4 · x > - 1

x > - 1 / 4

x > - 1

By (3):

4 · x + 5 < 175

4 · x < 170

x < 170 / 4

x < 85 / 2

x < 42.5

x < 43

Then, the number of integers within the simultaneous inequality is:
