The mean and median of the given data set are 5.55 and 4.

What are the mean and median?A data set's mean (average) is calculated by adding all of the numbers in the set, then dividing by the total number of values in the set. When a data set is ranked from least to greatest, the median is the midpoint. Identifying the median The data points should be arranged from smallest to largest. The median is the middle data point in the list if the number of data points is odd. The median is the average of the two middle data points in the list if the number of data points is even.

So, the data is:

[0, 0, 0, 0, 0, 1, 1, 2, 3, 4, 4, 4, 4, 4, 4, 5, 6, 6, 8, 55]

Order of operations was it evaluated correctly? 5^(2) + 1^(2) = 6(2) = 36EXPLAIN your reasoning. Thank you

Answers

The answer to the operation is as follows:

5^(2) + 1^(2) = 5*5 + 1*1 = 25 + 1 = 26.

Here, we have to remember PEMDAS. First, we solve parentheses, then exponents (or exponentiation operations); then, multiplications, divisions, and, after all this, addition and subtractions.

In the above operation, we solve first the raising of 5 to 2, then 1 raised to 2. We sum the result of both operations. So the value of 36 is not correct. The correct value is 26.

Find the domain of the logarithmic function and then graph the function. y= In (4x - 5) Find the domain of the function.

Answers

Answer:

Domain = ( 5/4 , ∞)

Explanations:

The logarithm function is given as:

y = ln (4x - 5)

the domain of the functions is a set of all the values of x that makes the function true (defined)

Note that the natural logarithm of a negative number is undefined. This means that the natural logarithm (ln) is only defined for positive numbers

This means that in y = ln (4x - 5), 4x -5 has to be greater than zero for the function to be defined.

Set 4x - 5 > 0

4x > 5

x > 5 / 4

Therefore, the domain of the function is a set of values greater than 5/4

Domain = ( 5/4 , ∞)

Looking at the equations after Elena started solving the system, we can see that the second equation is different.

Answers

Terrance’s error is that he limits the solution of the equation to one ordered pair

How to determine the error in Terrance’s claim?

The equation is given as

y - 4 = 1/2(x - 5)

The solution is given as

(5, 4)

The above solution is true

This is so because; when x = 5, the value of y is 4

i.e.

y - 4 = 1/2(5 - 5)

y - 4 = 0

y = 4

Next, we set x to another value (say x = 9)

So, we have

y - 4 = 1/2(5 - 9)

y - 4 = -2

y = 6

This means that the equation can have another solution

In this case, it is (9, 6)

Hence, one ordered pair cannot be the solution to the equation

-2×+5y=-13×+2y=11[tex] - 2 \times + 5y = - 1[/tex]

Answers

nealmiyasmith20, this is the solution:

-2× + 5y= -1

3× + 2y= 11

___________

Step 1: Isolating x on the first equation:

-2× + 5y= -1

-2x = - 1 - 5y

Dividing by -2 at both sides:

-2x/-2 = -1/-2 - 5y/-2

x = 1/2 + 5y/2

______________________

Step 2: Substituting x and solving for y on the second equation:

3× + 2y = 11

3 ( 1/2 + 5y/2) + 2y = 11

3/2 + 15y/2 + 2y = 11

19y/2 = 11 -3/2

19y/2 = 19/2

Multiplying by 2/19 at boths sides:

19y/2 *2/19 = 19/2 * 2/19

y = 1

___________________

Step 3: Substituting y and solving for x on the first equation:

-2× + 5y = -1

-2x + 5 * 1 = -1

-2x + 5 = -1

-2x = -1 - 5

-2x = -6

Dividing by -2 at both sides:

-2x/-2 = -6/-2

x = 3

Step 4: Proving that x = 3 and y = 1 are correct on the second equation:

3× + 2y = 11

3 * 3 + 2 * 1 = 11

9 + 2 = 11

11 = 11

We proved that x = 3 and y = 1 are correct

What is a triangle?

A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.

The sum of the angles of a triangle is always 180°

A triangle is formed when one side of triangle is greater than the difference of the two remaining sides, less than the sum of the two remaining sides.

If a, b and c are the sides of triangle,

I need help with all those questions in the image!

Answers

Answer:

The rate of change of elevation tends to a constant value.

Explanation:

The average rate of change of e(x) on the interval [a, b] defined as

[tex]m_{\text{avg}}=\frac{e(b)-e(a)}{b-a}[/tex]

which explicitly we can write as

[tex]m_{\text{avg}}=\frac{\sqrt[]{b-10}-\sqrt[]{a-10}}{b-a}[/tex]

Now, the question is, what happens to m_avg as we increase b while keeping a fixed?

As b becomes large then √b -10 becomes √b and b - a becomes b (since a is comparatively small); therefore, m_avg becomes

[tex]m_{\text{avg}}=\frac{\sqrt[]{b-10}-\sqrt[]{a-10}}{b-a}\Rightarrow\frac{\sqrt[]{b}-\sqrt[]{a-10}}{b}\Rightarrow\frac{\sqrt[]{b}}{b}[/tex][tex]\Rightarrow m_{\text{avg}}=\frac{\sqrt[]{b}}{b}[/tex]

which for any fixed value of b is a constant.

The same behaviour can be extrapolated by looking at the graph of e(x).

As can be seen from the graph, as x increases, the slope of the function becomes flatter and flatter, meaning it tends to be a constant. In other words, for large values of x, you can approximate the slope of the function by a straight line.

Answers

Ken will pay $ 871.25 for these items

Explanation

to find the total cost we need add the cost of the blocks to the cost of the total boards, so

Step 1

find the total cost of the blocks

a) when having the cost per unit and the amount, we just need to do a multiplication, so

[tex]\begin{gathered} total\text{ cost= rate*amount} \\ replace \\ tota\text{l cost of the blocks= 7.97}\frac{\text{ \$}}{block}*25\text{ Blocks} \\ tota\text{l cost of the blocks= \$ 199.25} \end{gathered}[/tex]

Step 2

now, the total cost of the boards:

[tex]\begin{gathered} total\text{ cost= rate*amount} \\ replace \\ tota\text{l cost of the boards= 14}\frac{\text{ \$}}{board}*4\text{8 boards} \\ tota\text{l cost of the boards= \$ 672} \end{gathered}[/tex]

Step 3

finally, add the costs to find the total

[tex]\begin{gathered} total\text{ cost= \$199.25+672} \\ total\text{ cost= 871.25} \end{gathered}[/tex]

therefore, Ken will pay $ 871.25 for these items
