Based on the angle of two-tangent theorem, the value of x in the image is: x ≈ 4.

The angle of two-tangent theorem states that when two tangent lines intersect outside of a circle, the angle that they form has a measure equal to half the positive difference between the measures of the arcs intercepted by the angle.

Applying the theorem, we have:

70 = 1/2[(360 - 27x + 2) - (27x + 2)]

140 = 360 - 27x + 2 - 27x - 2

140 = 360 - 54x

140 - 360 = -54x

-220 = -54x

-220/-54 = x

x ≈ 4

Answer:

y because its y i really dont no

Answer:

c(x,y)/(x²+y²)

Step-by-step explanation:

Since E​(x,y) = -∇V (x,y ) and V(x,y) =c ln (ro/√ x²+y²)

Let ro/√(x²+y²) = u and √(x²+y²) = v

dV/du = c/u = c√(x²+y²)/ro,

du/dv =  -ro/(x²+y²) = -ro/² and dv/dx = x/√(x²+y²)

Using the chain rule,

So dV/dx = dV/du × du/dv × dv/dx

= c√(x²+y²)/ro × -ro/(x²+y²) × x/√(x²+y²)

dV/dx = -cx/(x²+y²)

- dV/dx = -(-cx/(x²+y²)) = cx/(x²+y²)

Also, dv/dy = y/√(x²+y²)

Using the chain rule

dV/dy = dV/du × du/dv × dv/dy

= c√(x²+y²)/ro × -ro/(x²+y²) × y/√(x²+y²)

dV/dy = -cy/(x²+y²)

- dV/dy = -(-cy/(x²+y²)) = cy/(x²+y²)

E(x,y) = -∇V (x,y )

= -(dV/dx)i + [-(dV/dy)]j

= [cx/(x²+y²)]i +[ cy/(x²+y²)]j

= c(x,y)/(x²+y²)

Therefore, the first option is correct

Yes, based on the 99% confidence interval (0.297, 0.503), there is convincing evidence of a difference in the proportion of "big" bank customers who bank with more than one bank compared to the "small" customers who bank with more than one bank.

The confidence interval (0.297, 0.503) represents the range of values within which the true difference in proportions between the two customer groups is likely to fall with 99% confidence. Since the interval does not include zero (0), we can conclude that there is a statistically significant difference between the proportions.

To further explain, the confidence interval was constructed using the sample proportions and the standard error. The sample proportion for the "big" customers who bank with other banks is 160/200 = 0.8, and for the "small" customers, it is 120/300 = 0.4. The standard error takes into account the sample sizes and proportions, and it measures the uncertainty in the estimation.

Since the confidence interval does not include zero, it indicates that the true difference in proportions is unlikely to be zero. In other words, there is strong evidence that the proportion of "big" bank customers who bank with more than one bank is higher than the proportion of "small" customers who do the same.

Therefore, based on the provided data and the confidence interval, we can conclude that there is convincing evidence of a difference in the proportion of "big" bank customers who bank with more than one bank compared to the "small" customers who bank with more than one bank.

Answer:

1)  Mean = $75812.50

    Median = $74000

    Mode = $73100

2)  Mean = 24.5

     Median = 24.33333...

     Modal class = 29 - 33

Step-by-step explanation:

Definitions

Given data:

Mean

\(\begin{aligned}\textsf{Mean}&=\dfrac{71500+74900+69700+82300+78500+73100+73100+83400}{8}\\ &= \dfrac{606500}{8}\\&=75812.50\end{aligned}\)

Median

Place the data values in order of size (smallest to largest):

As there is an even number of data values, the median is the mean of the middle two values:

\(\implies \sf Median=\dfrac{73100+74900}{2}=74000\)

Mode

The most frequently occurring data value is $73100.  Therefore:

\(\implies \textsf{Mode} = 73100\)

With grouped data, we can only estimate the mean and median.

Mean

To find an estimate of the mean, assume that every reading in a class takes the value of the class midpoint.

The number of days is the frequency (f).

Add a class midpoint (x) and an fx column to the table:

\(\begin{array}{|c|c|c|c|}\cline{1-4}\vphantom{\dfrac12} \sf Number\;of\;sales&\textsf{Number of days, $f$}&\textsf{Class midpoint, $x$}&fx\\\cline{1-4}\vphantom{\dfrac12}14-18&5&16&80\\\cline{1-4}\vphantom{\dfrac12}19-23&9&21&189\\\cline{1-4}\vphantom{\dfrac12}24-28&6&26&156\\\cline{1-4}\vphantom{\dfrac12}29-33&10&31&310\\\cline{1-4}\vphantom{\dfrac12}\sf Totals&\sum f=30&&\sum fx=735\\\cline{1-4}\end{array}\)

\(\textsf{Mean}=\dfrac{\sum fx}{\sum f}=\dfrac{735}{30}=24.5\)

Median

To find an estimate for the median, use linear interpolation.

Add a cumulative frequency column to the table:

\(\begin{array}{|c|c|c|}\cline{1-3}\vphantom{\dfrac12} \sf Number\;of\;sales&\textsf{Number of days}&\textsf{Culmulative frequency}\\\cline{1-3}\vphantom{\dfrac12}14-18&5&5\\\cline{1-3}\vphantom{\dfrac12}19-23&9&14\\\cline{1-3}\vphantom{\dfrac12}24-28&6&20\\\cline{1-3}\vphantom{\dfrac12}29-33&10&30\\\cline{1-3}\end{array}\)

Find which class the median is in.

Since n/2 = 30/2 = 15, there are 15 values less than or equal to the median. This means the median must be in the 24-28 class.

Therefore:

To find the median, m:

\(\begin{aligned}\dfrac{a_1}{b_1}=\dfrac{a_2}{b_2} \implies \dfrac{m-23.5}{5}&=\dfrac{1}{6}\\\\ 6(m-23.5)&=5\\\\6m-141&=5\\\\6m&=146\\\\m&=24.3333...\end{aligned}\)

Therefore, the median is 24.3333...

Mode

The modal class is the class with the highest frequency density.

As all the classes are the same width, this is the class with the highest frequency.

Step-by-step explanation:

The function graphed on the axes below as a piecewise function is,

⇒ f (x) = 2x - 1 ; x > 2

          = 3  ; x ≥ - 3

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Now, By the graph;

For upper line,

The equation of line is passing though points (4, 7) and (5, 9).

Hence, The equation of line is,

⇒ y - 7 = (9 - 7) / (5 - 4) (x - 4)

⇒ y - 7 = 2 (x - 4)

⇒ y - 7 = 2x - 8

⇒ y = 2x - 1

For x > 2

And, For lower line,

The equation of line is passing though points (-4, 3) and (-5, 3).

Hence, The equation of line is,

⇒ y - 3 = (3 - 3) / (-5 + 4) (x - (-4))

⇒ y - 3 = 0 (x + 4)

⇒ y - 3 = 0

⇒ y = 3

For x ≥ - 3

Hence, The piecewise function is,

⇒ f (x) = 2x - 1 ; x > 2

x= ln(2).

\(8e^{x} =16\)

\(\frac{8e^{x}}{8} =\frac{16}{8} \\ \\e^{x} =2\)

\(ln(e^{x} )=ln(2)\\ \\x=ln(2)\)

If the result is correct, if variable "x" is substituted by the calculated value (ln(2)) in the original equation, it should return the same value in both sides of the equal (=) sign.

Substituting "x" by the value:

\(8e^{ln(2)} =16\\\\16=16\)

Answer:

f(x) = - 2x + 4

Step-by-step explanation:

Since we are only trying to move the graph up 3 units, the slope does not change. So, it would be -2.

We also know that the 1 in f(x)= -2x + 1 is the y-intercept (y=mx+b). But again, we are moving the graph 3 units up, so we have to add 3. That makes it 4 (3+1=4).

So, the new equation would be f(x) = -2x + 4

Step-by-step explanation:

it simply means that g(x) is f(x) just shifted 3 units upwards.

that means nothing else changes, only whatever y result f(x) produces is increased by 3.

so,

g(x) = f(x) + 3 = -2x + 1 + 3 = -2x + 4

therefore, as domain and range were the whole set of real numbers, the addition of 3 does not make any difference in relation to infinity. so, they remain unchanged.

the slope stays the same (g(x) is simply a parallel line to f(x)).

the y-intercept (the y-value when x = 0) also increases by 3, and is 4.

the x-intercept (the x-value when y = 0) changes :

0 = -2x + 4

2x = 4

x = 2

the x-intercept is 2.

Answer:

A) y = 3x -2 is the answer

Step-by-step explanation:

The y-intercept is -2

The slope is going up 3 and right 1 which is 3/1 and 3 divide by 1 is 3.

The amount of blue paint and red paint that you use will be 3 quarts and 2 quarts, respectively.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

You mix 1/2 quart of blue paint for every 1/3 quart of red paint to make 5 quarts of purple paint.

Let 'x' be the amount of blue paint and 'y' be the amount of red paint. Then the equations are given as,

x / y = (1/2) / (1/3)

x / y = 3/2                        ...1

x + y = 5                          ...2

From equations 1 and 2, then we have

(3/2) y + y = 5

(5/2) y = 5

y = 2 quart

Then the value of 'x' is given as

x + 2 = 5

x = 3 quart

In order to solve for x, you simply take into account the previous situation, segements CB and BA are equal to CA. You put this in an algebraic way, and solve for x. You proceed as follow:

x - 8 + 11 = 2x - 8 add 8 both sides

x + 11 = 2x subtract x both sides

11 = x

Hence, x is equal to 11

If Gavin contributes towards a Pension fund (7,5% of his Basic Salary), then his net salary will be reduced by the amount he contributed towards pension fund i.e. R652.5.

1.1 Name of employee is Gavin Pillay. 1.2 UIF stands for Unemployment Insurance Fund. UIF is a benefit to provide short-term relief to workers who lose their jobs, or can't work due to illness, maternity or adoption leave. 1.3 The UIF paid by Gavin is calculated correctly.

Firstly, we need to calculate Gross Salary of Gavin, which is given as: Basic Salary + Overtime + M = R8700 + R1200 + R3201 = R13101Then, calculate total deductions from gross salary.

Total Deductions = PAYE + UIF = R1200 + 87 = R1287Hence, Gavin's net salary = Gross salary - Total Deductions = R13101 - R1287 = R11814Therefore, UIF paid by Gavin is calculated correctly as R87.1.4 This payslip is for the month of May i.e.

31/05/2023.1.5 Basic salary of Gavin = R8700. Deduct 7.5% of his basic salary to calculate his pension fund contribution. Pension Fund Contribution = 7.5/100 x R8700 = R652.5.1.6

Total deductions of Gavin includes PAYE, UIF and pension fund contribution.

Therefore, Total Deductions = PAYE + UIF + Pension Fund Contribution = R1200 + R87 + R652.5 = R1939.5.1.7

Step-by-step explanation:

The equation that is given in this item can be written for clarity as follows:
