D 857
Answers
Answer:
That day Jiao spent $CNY 514.29.
Step-by-step explanation:
Given that Jiao is a Chinese student visiting family in the United States, and she spent $ 79 on dinner for her family one evening, if the exchange rate that day is UDS to CNY = 6.51, to determine approximately how much money did she spend in CNY the following calculation must be performed:
79 x 6.51 = X
514.29 = X
Therefore, that day Jiao spent $ CNY 514.29.

Find the solution of the following equation whose argument is strictly between 90° and 180°.
Answers
Answer:
180degreesStep-by-step explanation:
Given the complex value
z² = -81i
z = (-81i)^1/2
Get the argument of -81i
theta = arctan(y/x)
theta = arctan(-81/0)
theta = -90degrees
theta = -π/2
Since tan is negative in the secind quadrant
theta = π - π/2
theta = π/2
According to demoivres theorem
theta = 1/2 * π/2
theta = π
theta = 180degrees

Mika is a local farmer who is interested in how often residents in her town go to a farmer's market each month. She surveys 124 families and finds that, on average, those families visit a farmers' market 4.2 times per month with a sample standard deviation of 1.3. If Mika wants to be 99% confident (z=2.58) using this sample, what should her margin of error be and what does it mean?
Answers
Answer:
The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.
Step-by-step explanation:
Margin of error
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
Standard deviation of 1.3
This means that [tex]\sigma = 1.3[/tex]
She surveys 124 families
This means that [tex]n = 124[/tex]
Margin of error and meaning:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]M = 2.58\frac{1.3}{\sqrt{124}}[/tex]
[tex]M = 0.3012[/tex]
The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

Identify the functions that exhibit a removable discontinuity.
Answers
Answer:
h(x) and k(x)
Step-by-step explanation:
The functions that exhibit a removable discontinuity are function i(x) and function k(x)
What is a quadratic equation?"An equation of the form ax² + bx + c = 0 is a quadratic equation."
What is a function?"It defines a relation between input and output values."
What is discontinuous function?"This function has a discontinuity at one or more values mainly because of the denominator of a function is being zero at that."
What is removable discontinuity?"If adjusting the function's value at the point of discontinuity will render the function continuous, then such discontinuity is called removable discontinuity."
What is non-removable discontinuity?"If adjusting the function's value at the point of discontinuity will not render the function continuous, then such discontinuity is called non-removable discontinuity."
For given question,
1) Consider a function [tex]f(x)=\frac{x^{2} +4x-21}{x^{2} -13x+42}[/tex]
If we factorize the quadratic equation at numerator and denominator then the given function would be,
[tex]f(x)=\frac{(x-3)(x+7)}{(x-7)(x-6)}[/tex]
We can observe that the function f(x) is discontinuous at x = 7 and x= 6.
So, the function f(x) has non-removable discontinuity.
2) Consider a function [tex]g(x)=\frac{2x^{2} -5x+12}{2x+3}[/tex]
We can observe that the function g(x) is discontinuous at x -3/2.
We cannot factorize the quadratic equation at numerator.
So, the function g(x) has non-removable discontinuity.
3) Consider a function [tex]h(x)=\frac{x-3}{x^{2} -9}[/tex]
If we factorize the quadratic equation at denominator then the given function h(x) would be,
[tex]\Rightarrow h(x)=\frac{(x-3)}{(x-3)(x+3)}\\\\\Rightarrow h(x)=\frac{1}{x+3}[/tex]
We can observe that the function h(x) is discontinuous at x = -3
So, the function h(x) has non-removable discontinuity.
4) Consider a function [tex]i(x)=\frac{x^{2} -8x+15}{x-5}[/tex]
If we factorize the quadratic equation at numerator then the given function would be,
[tex]\Rightarrow i(x)=\frac{(x-5)(x-3)}{x-5}\\\\ \Rightarrow i(x)=x-3[/tex]
We can observe that the function i(x) is a continuous function.
So, the function i(x) has removable discontinuity.
5) Consider a function [tex]j(x)=\frac{x+4}{-2x+8}[/tex]
We can observe that the function j(x) is discontinuous at x = 4
And the function j(x) has non-removable discontinuity.
6) Consider a function [tex]k(x)=\frac{2x^{2} +x-15}{2x-5}[/tex]
If we factorize the quadratic equation at numerator then the given function would be,
[tex]\Rightarrow k(x)=\frac{(x+3)(2x-5)}{(2x-5)}\\\\ \Rightarrow k(x)=x+3x^{2}[/tex]
We can observe that the function k(x) is a continuous function.
So, the function k(x) has removable discontinuity.
Therefore, the functions that exhibit a removable discontinuity are function i(x) and function k(x)

Answer:
arc FG = 115°
arc EG = 165°
Step-by-step explanation:
The first step is to understand how these arcs are arranged on a circle. The next step is to realize the whole is the sum of the parts. Arcs have the same measure as their central angle. A circle totals 360°.
arc EF + arc FG = arc EFG . . . . parts of an arc add to give the whole arc
80° + arc FG = 195°
arc FG = 115° . . . . . . . . . subtract 80°
__
Similarly, parts of a circle add to give the whole circle.
arc EFG + arc EG = 360°
195° + arc EG = 360°
arc EG = 165° . . . . . . . . . subtract 195°

Answers
Answer:
She receives 700 country A dollars.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
1.4 country a dollars Per country B dollar
She exchanges 500 country B dollars, so:
1.4 country A dollars - 1 country B dollar
x country A dollars - 500 country B dollars

Answer:
The given numerical value is a Parameter.
Step-by-step explanation:
Given - For a certain movie 64.3% of the 112 members of the audience were females.
To find - Determine whether the underlined numerical value is a parameter or a statistic.
Proof -
Given that, 64.3% of the 112 members of the audience were females.
Now,
64.3% of 112 = [tex]\frac{64.3}{100}*112[/tex] = 72.016
Since it is not a perfect number
And Human can not be in fraction
So,
The given numerical value is a Parameter.

Answers
Answer:
Your answer would be x = 1/2
Step-by-step explanation:
1/x = 2
You would divide x on both sides...then they would cancel each other out.
But now you're left with...
1 = x•2
So, re-order the terms so constants are on the left
1 = 2x
Divide 2 on both sides...
Now you're left with
