Answer:

(a) $R(x)=-0.02x^2+610x$

(b) $R'(x)=-0.04x+610$

(c)R'(5400)=$394

Step-by-step explanation:

Given that x is the quantity demanded and the speaker's unit price (in dollars) is p where:

p = −0.02x + 610 (0 ≤ x ≤ 20,000)

(a)Revenue function R.

Revenue = Price X Quantity Demanded

Therefore:

R(x)=xp

$=x(-0.02x + 610)\\R(x)=-0.02x^2+610x$

(b)Marginal revenue function R'(x)

If $R(x)=-0.02x^2+610x$

Then, the marginal revenue function

$R'(x)=-0.04x+610$

(c)We want to compute R'(5,400)

$R'(5400)=-0.04(5400)+610\\R'(5400)=394$

From the above, we can infer that the revenue that will be generated on the sales of the 5401st item is $394.

Consider the statement, "Confidence intervals are underutilized" and explain what the implications might be of using or not usin

nataly862011 [7]

Answer:

Step-by-step explanation:

Confidence intervals have been underutilized prior to this time.

The implications of not using confidence intervals include:

- The under-representation or over-representation of research results that amounts from the use of a single figure to represent a statistic.

- In Market Research analysis, neglecting the use of confidence intervals will increase the risk of your portfolio.

Implications/Importance of using confidence intervals include:

- Calculation of confidence interval gives additional information about the likely values of the statistic you are estimating.

- In the presentation and comprehension of results, confidence intervals give more accuracy from the data or metrics captured.

- Given a sample mean, confidence intervals show the likely range of values of the population mean.

Greg ran 3 times as far as jed.rj ran 0.1times as far as Greg. If jed ran25 yards, how far did Greg and rj run

azamat

Greg's distance is 3 times than Jed. so, 25 yards * 3 = 75 yards. And RJ ran only 0.1 times than Greg (75 yards). So, it should be 7.5 yards

Use two sets of coordinates to write an equation<br> to describe the relationship.

Irina-Kira [14]

Answer/Step-by-step explanation:

An equation that describes the relationship can be written as $y = mx$ .

Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:

$\frac{y_2 - y_1}{x_2 - x_1} = \frac{280 - 140}{4 - 2} = \frac{140}{2} = 70$

Substitute m = 70 into $y = mx$

The equation would be:

$y = 70x$

This equation can be interpreted as follows:

The heart's resting rate is 70 beats each minute.

If you can answer this question you'll get brainliest.

igomit [66]

Answer:

Volume = 66 cm³

Step-by-step explanation:

Area of the oblique triangular prism = Area of the triangular base × Vertical height from the base

From the figure attached,

Area of the triangular base = $\frac{1}{2}(\text{Base})(\text{Height of the right triangle})$

= $\frac{1}{2}(3)(4)$

= 6 cm²

Vertical height of the given oblique prism = 11 cm

Volume of the given oblique prism = 6 × 11

= 66 cm³
