Answers

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.

What is the formula for calculating a residual value

Answers

The formula to figure residual value follows: Residual Value = The percent of the cost you are able to recover from the sale of an item x The original cost of the item. For example, if you purchased a $1,000 item and you were able to recover 10% of its cost when you sold it the residual value is $100!!

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.

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.

Answers

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.

If a, b are real numbers and 7a + i(3a - b) = 14 - 6i , then find the values of a and b.

Answers

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.
