First, let's write the data set in crescent order:

The mean is given by the sum of all values divided by the number of values:

The median is given by the central value of the set in crescent order. Since this set has 13 values, the median is the 7th value:

The mode is the value that repeats the most. Looking at the set, the value that repeats the most (three times) is 50, so the mode is 50.

To solve this inequality add 1 to both sides

Now divide both sides by 5

The solutions lie in the area left to the number 4

For the second inequality

Add first we will add the like terms in the left side

Now add 2 for both sides

We need to divide both sides by -1, but we should reverse the sign of inequality

We reversed the sign of inequality when divides it by -ve number

Since 2 < 3

Then if we divide both sides by -1, then it will be

-2 < -3 which is wrong -2 greater than -3, then we should reverse the sign of inequality if we multiply or divide it by a negative number

Then the solutions of the 2nd inequality lie right to -3

Let us draw them

The red part is the solution to the 1st inequality

The blue par is the solution to the 2nd inequality

The expression that can be said to as equal to log(xy / z) is the expression logx + logy - logz and this can be found out through the logarithmic identities.

The “basic” logarithmic function can be seen as the the function, y=logbx, where x, b>0 and b≠1.

In the kind of complex analysis that we come across three types of logarithms namely ln, log and Log are used.

In mathematics log tends to always mean the natural log.

Log is often seen as the main and principal branch that comes under the complex logarithm.

Logarithmic functions are said as important only largely because of their relationship to the kind of exponential functions. Logarithms can also be used to solve any kind of exponential equations and thus help to explore the properties of exponential functions.

Jason, this is the solution:

Walter's daily wage = $ 50

Tips = 15% of the total cost of the dinner he serves

Tuesday earnings = $ 170

Therefore,

Tips = 170 - 50

Tips = 120

For finding the cost of the dinners, we use Direct Rule of Three, as follows:

Percentage Cost

15 120

100 x

_____________________

120 * 100 = 15 * x

12,000 = 15x

Dividing by 15 at both sides:

15x/15 = 12,000/15

x = 800

The total cost of the dinners Walter serverd on Tuesday was $ 800

The width of the smaller rectangle is 4 inches.

A rectangle has four sides, but because the sides are paired, it only has two distinct dimensions. The width is traditionally the shortest of these two dimensions, but when the rectangle is shown lying on its side, the horizontal side is commonly referred to as the width.

Given:

The dimensions of the smaller rectangle are:

Length = 8 inches

Width = x inches

The dimensions of the larger rectangle are:

Length = 10 inches

Width = 5 inches

Using proportion we determine the value of x,

[tex]\frac{8}{x} = \frac{10}{5}[/tex]

Cross-multiply the terms,

8 × 5 = 10x

x = 40/10 = 4

Answer: 3.853 micrograms

Answer:

Step-by-step explanation:

You want a sequence of transformations that maps ∆ABC to ∆A'B'C' where the vertices are A(-5, 3), B(-2, 3), C(-4, 1), A'(8, -2), B'(5, -2), and C'(7, 0).

Segment AB is a 3-unit line segment directed to the right. Segment A'B' is a 3-unit line segment directed to the left. This means there is no dilation involved in the transformation. At least, the figure has been reflected left-to-right.

Point C is below segment AB, while point C' is above segment A'B'. This means the figure has also been reflected top-to-bottom.

Together these reflections can be accomplished by either of reflection across the origin, or rotation 180° about the origin.

The reflected figure would leave A' at (5, -3). Its location at (8, -2) means the figure has also been translated to the right and up.

Translation to the right has been by 8 -5 = 3 units.

Translation up has been by -2 -(-3) = 1 unit.

According to the secant-tangent theorem, we have the following expression:

Now, we solve for x.

Then, we use the quadratic formula:

Where a = 1, b = 6, and c = -315.

If j(x) = 4^(x - 2), the solving the given expression [j(x + h) - j(x)]/h gives;

[j(x + h) - j(x)]/h = (4^(x - 2))(4^(h) - 1)]/h

We are given the function as;

j(x) = 4^(x - 2)

Now, we want to solve the expression;

[j(x + h) - j(x)]/h

This gives us;

j(x + h) = 4^(x - 2 + h)

Thus, our expression is now;

[j(x + h) - j(x)]/h = [4^(x - 2 + h) - 4^(x - 2)]/h

Now, according to laws of exponents, we know that;

y³ × y² = y³ ⁺ ²

Thus;

4^(x - 2 + h) = 4^(x - 2) × 4^h

Therefore;

[4^(x - 2 + h) - 4^(x - 2)]/h = (4^(x - 2))(4^(h) - 1)]/h

According to the question,

We have the following information:

-1.2 [tex](\frac{2}{5} )[/tex] ÷ -2

Now, we have to solve this problem and fill the blanks at the same time.

Now, the first step would be to write the question.

So, for the first blank we have:

-1.2 [tex](\frac{2}{5} )[/tex] ÷ -2

Now, the required number is (2/5).

Now, the next step is to multiply -1.2 with 2/5:

-2.4/5

-0.48

So, the second blank can be filled by -0.48.

Now, the third step would be to divide -0.48 by -2:

-0.48÷-2

0.24

So, the next blank can be filled by 0.24.

c) The Marginal Propensity to Consume (MPC), rounded to three decimal places, is 0.820.

d) The Marginal Propensity to Save (MPS), rounded to three decimal places, is 0.180.

The average propensity to consume is the ratio of consumption expenditures to the total consumers' disposable income.

The average propensity to save is the inverse of the APC. It shows the rate of or total disposable income reserved instead of being consumed.

The marginal propensity to consume is the ratio of consumption based on additional income.

The marginal propensity to save is the inverse of the MPC, showing the percentage of the additional income saved instead of being consumed.

APC = 91.6%
