Answer:
CV of Bank A = 6.4
CV of Bank B = 7.1
CV of Bank B is more than CV of Bank A
Step-by-step explanation:
Bank A
6.6, 6.7, 6.7, 6.8, 7.0, 7.3, 7.5, 7.7, 7.8, 7.8
[tex]Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}\\Mean = \frac{6.6+6.7+6.7+6.8+7.0+7.3+7.5+7.7+7.8+ 7.8}{10}\\Mean =7.19[/tex]
Standard deviation =[tex]\sqrt{ \frac{\sum(x-\bar{x})^2}{n}}=0.461[/tex]
[tex]CV = \frac{\sigma}{\bar{x}} \times 100\\CV = \frac{0.461}{7.19} \times 100=6.4[/tex]
Bank B
4.0, 5.5, 5.8, 6.2, 6.6, 7.6, 7.7, 8.5, 9.4, 9.7
[tex]Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}\\Mean = \frac{4.0+5.5+5.8+6.2+6.6+ 7.6+ 7.7+8.5+9.4+9.7}{10}\\Mean =7.1[/tex]
Standard deviation =[tex]\sqrt{ \frac{\sum(x-\bar{x})^2}{n}}=1.718[/tex]
[tex]CV = \frac{\sigma}{\bar{x}} \times 100\\CV = \frac{1.718}{7.1} \times 100=24.2[/tex]
CV of Bank A = 6.4
CV of Bank B = 7.1
CV of Bank B is more than CV of Bank A

Describe how to select a stratified random sample of 36 people hired by ETS to score the AP Statistics Exams. Explain your choice of strata.
Answer:
The strata will be the category of people with at least 3 years of working experience scoring AP Statistics
Step-by-step explanation:
The strata will be the category of people with at least 3 years of working experience scoring AP Statistics Exams.
I will use this strata because it is only those with a track record of scoring AP Statistics Exams that can rightly score for ETS. People who don't have the right amount of experience of scoring AP Statistics exam may need some training because they need to understand the specifics on how to grade some questions and respective answers.
If a, b are real numbers and 7a + i(3a - b) = 14 - 6i , then find the values of a and b.
If a, b are real numbers and 7a + i(3a - b) = 14 - 6i, then find the values of a and b. Therefore, the value of a = 2 and the value of b = 12. 3.
The value of the variables 'a' and 'b' of the complex equation will be 2 and 12, respectively.
What is a complex number?The complex number is the combination of the real part and the imaginary part. Then the complex number is given as a+bi where the value of i is √(-1) and the value of i² is -1.
The equation is given below.
7a + (3a - b)i = 14 - 6i
Compare the real part of the equation, then we have
7a = 14
a = 14 / 7
a = 2
Compare the imaginary part of the equation, then we have
3a - b = - 6
3 x 2 - b = -6
6 - b = - 6
b = 6 + 6
b = 12
The value of the variables 'a' and 'b' of the complex equation will be 2 and 12, respectively.

Reading a text message takes your eyes off the road for about 4.6 seconds according
to a recent study. If you are traveling 60 mph and check a text message while you
are driving, how far do you travel (in feet) with your eyes not on the road? Round
your answer to the nearest foot.
Answer:
d = 404.8 feet
Step-by-step explanation:
We take our eyes off the road for about 4.6 seconds according to a recent study.
Speed, v = 60 mph
We need to find the distance travel by you with your eyes not on the road. Let it is d.
Speed, v = d/t
d = vt
We know that, 1 mile = 5280 feet
[tex]d=\dfrac{60\times 5280\ \text{feet}}{3600\ s}\times 4.6\ s\\\\=404.8\ \text{feet}[/tex]
Hence, the required distance is 404.8 feet.

Chris paid $9.18 for a necklace. This amount includes a sales tax of 8%. What was the cost of the necklace before tax?
Answer:
8.5 or 8.50
Step-by-step explanation:
None for now
"Not putting it here"
The cost of the necklace before tax, for which Chris paid $9.18 including the sales tax of 8% is $8.5.
What is percentage increase ?Percentage increase is the amount added to the initial value in the percentage part.
Chris paid $9.18 for a necklace. This amount includes a sales tax of 8%.
Let the cost of the necklace before tax is x dollars. Now, the 108% of the x is $9.18. Thus,
[tex]x\times\dfrac{100+8}{100}=9.18\\x=\dfrac{9.18\times100}{108}\\x=8.5[/tex]
Hence, the cost of the necklace before tax, for which Chris paid $9.18 including the sales tax of 8% is $8.5.

I mean there isn't much too this problem just fit in the values into the answers, so the correct answer is c because 16 + 0.55n is sixteen dollars for the trophy and 55 cents per letter in the engraving. Also, the other store sells the trophy for 22 dollars and 25 cents per letter on the engraving.
Answer:
a
Step-by-step explanation:
if you look at the equation, you can see there is an equal sign, so both costs must be the same. this marks out c and d.
each side of the equation has to be paired with one another. 16 and .55 have to be together, and 22 and .25 have to be together. in b, they are mixed up, so that makes it wrong.

What is the formula for calculating a residual value
The residual value indicates how well the regression model fits the observed data, with a residual of zero indicating a perfect fit.
In the context of linear regression analysis, the residual value represents the difference between the observed value of the dependent variable and the predicted value. The formula for calculating the residual value can be expressed as:
Residual = Observed Value - Predicted Value
To calculate the residual value, you need to have a regression model that predicts the value of the dependent variable based on the independent variable(s). Once you have the predicted value, you subtract it from the corresponding observed value to obtain the residual.
For example, if you have an observed value of 10 and the predicted value from the regression model is 8, the residual would be:
Residual = 10 - 8 = 2
The residual value indicates how well the regression model fits the observed data, with a residual of zero indicating a perfect fit.
