Answer:B
Step-by-step explanation:
The coordinates of the image of the rotation of the point Q is:
Q' = (4, 2)
What is the image of the rotation?
We can see that the original coordinates of point Q are (-4, 0).
If we apply a rotation of 180° about the point (0, 0), it is equivalent to a reflection around the y-axis.
It only changes the sign of the x-component.
Then the image of the rotation is:
Q' = (4, 0)

j. Is interest compounded annually the same as simple interest? Explain
Answers
Step-by-step explanation:
Simple interest formula
[tex]A = P (1 + rt)[/tex]
Compound interest formula
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
a.
[tex]A = 5000 (1 + 0.025*1)\\A=5000(1.025)\\A=5125[/tex]
Simple interest is $125
b
. [tex]A = 5000 (1 + \frac{0.025}{1})^{1*1} \\A=5000(1.025)\\A= 5125[/tex]
Compound interest is $125
c. the result for both a and b are the same
d.
[tex]A = 5000 (1 + 0.025*3) \\A=5000(1.075) \\A=5375[/tex]
the simple interest is $375
e
. [tex]A = 5000 (1 + \frac{0.025}{1})^{1*3}] \\A=5000(1.025)^3 \\A=5000(1.077)\\A= 5385[/tex]
the compound interest is $385
f. the result compared, compound interest is $10 more than simple interest
g.
[tex]A = 5000 (1 + 0.02*6) \\A=5000(1.12) \\A=5600[/tex]
the simple interest is $600
h.
[tex]A = 5000 (1 + \frac{0.02}{1})^{1*6}] \\A=5000(1.12)^6 \\A=5000(1.9738) \\A= 9869[/tex]
the compound interest is $4869
i. the result from g and h, h is over 8 times bigger than g.
j. interest compound annually is not the same as simple interest, only for the case of a and b seeing that it is for 1 year. but for 2years and above there is difference as seen in c to h

[tex]\frac{???}{x-2}/\frac{x^{2}-1 }{x^{2} -4x+4} =\frac{5(x-2)}{x-1}[/tex]
Answers
Given:
The equation is
[tex]\dfrac{???}{x-2}/\dfrac{x^2-1}{x^2-4x+4}=\dfrac{5(x-2)}{x-1}[/tex]
To find:
The missing value.
Solution:
Let the missing value be k.
[tex]\dfrac{k}{x-2}/\dfrac{x^2-1}{x^2-4x+4}=\dfrac{5(x-2)}{x-1}[/tex]
[tex]\dfrac{k}{x-2}\times \dfrac{x^2-2(x)(2)+2^2}{x^2-1^2}=\dfrac{5(x-2)}{x-1}[/tex]
Using the formulae [tex](a-b)^2=a^2-2ab+b^2[/tex] and [tex](a-b)(a+b)=a^2-b^2[/tex].
[tex]\dfrac{k}{x-2}\times \dfrac{(x-2)^2}{(x-1)(x+1)}=\dfrac{5(x-2)}{x-1}[/tex]
[tex]\dfrac{k(x-2)}{(x-1)(x+1)}=\dfrac{5(x-2)}{x-1}[/tex]
Cancel out the common factors from both sides.
[tex]\dfrac{k}{x+1}=5[/tex]
Multiply both sides by (x+1).
[tex]k=5(x+1)[/tex]
Therefore, the missing value is 5(x+1).

The life expectancy of Timely brand watches is normally distributed with a mean of 4 years and a standard deviation of 8 months. Ninety-five percent of the watches will have a life expectancy of at least how many months
Answers
Answer:
63.68 months
Step-by-step explanation:
We solve this question with z score formula
z = (x-μ)/σ, where
x is the raw score ???
μ is the population mean = 4 years
Since the final answer would be in months, we would convert mean to months
= 1 year = 12 months
4 years = x months
= 12 × 4 = 48 months
σ is the population standard deviation = 8 months
z = the z score for 95% confidence interval = 1.96
1.96 = x - 48/8
1.96 × 8 = x - 48
15.68 = x - 48
x = 15.68 + 48
x = 63.68 months

Suppose you want to find the average household income in America. So you pick 10 households from each state (a total of 500 households) and find their income.
What is the population? What is the parameter you want to find?
Answers
Answer:
Step-by-step explanation:
The purpose of the experiment is to find the average or mean amount of household income in America.
Household Income simply means the total income of a household - which is the sum of income earned by each member of the household. This study aims to find the average of this household, across the Americas.
For your analysis, you pick 10 households from each state of the country (or continent). A total of 500 households implies 500/10 = 50 states
WHAT IS THE POPULATION?
The population in this study is: the total population of American households OR the total number of households in America. The sample on the other hand, is the 500 households directly involved in the study.
WHAT IS THE PARAMETER YOU WISH TO FIND?
The parameter you wish to find is: mean (or average) household income in America.
