The following table shows summary statistics, in thousands, for the number of electrical workers and the number of concrete workers in the construction industry each month for the past 5 years. Based on the 1.5×IQR rule for outliers, which of the following statements is a correct comparison of the two distributions?

The electrical workers data is correct comparison of the two distributions based on the 1.5× IQR rule for outliers.

Explanation:

Outlier> 1.5 *IQR + 3rd Quartile

Outlier < 1st Quartile-1.5 *IQR

where

Interquartile Range (IQR) = 3rd Quartile- 1st Quartile

IQR (electrical) = 320-278= 42

IQR (concrete) = 308- 262= 46

Outlier for Electrical Co workers=

Outlier> 1.5 *IQR + 3rd Quartile= 1.5*42 + 320= 63+320= 383

Outlier < 1st Quartile-1.5 *IQR=278-1.5*42=278-63= 215

The minimum for electrical workers is 239 and maximum is 330.

215 < 239

383> 330

By comparing the values we find there are no outliers in the electrical workers data.

Outlier for Concrete Co workers=

Outlier> 1.5 *IQR + 3rd Quartile= 1.5*46 + 308= 69+308= 377

Outlier < 1st Quartile-1.5 *IQR=262-1.5*46=262-69= 193

The minimum for concrete workers is 186 and maximum is 335.

377>335

193>186 The minimum is the outlier.

By comparing the values we find there is one outlier in the concrete workers data.

Answer from: Quest

You need to figure out at which x-value does the graph has a tangent line slope of -1.remember, the derivative is the slope of the tangent line. so find the derivative function and set it to equal -1 to find the x-value that will have a tangent line slope of 0.differentiate with the chain rule. $\begin{aligned} f(x) & = (0.5)^{2x} \\ f'(x) & = 0.5^{2x} \cdot \ln(0.5) \cdot (2x)' \\ f'(x) & = 0.5^{2x} \cdot \ln(0.5) \cdot 2 \\ f'(x) & = 2\ln(0.5) \cdot 0.5^{2x} \end{aligned}$ set the derivative to equal -1 and solve for x. $\begin{aligned} -1 & = 2\ln(0.5) \cdot 0.5^{2x} \\ -\frac{1}{2} & = \ln(0.5) \cdot 0.5^{2x} \\ -\frac{1}{2\ln(0.5)} & = 0.5^{2x} \end{aligned}$ take log base 10 of both sides. also recall that $\log_c(m^n) = n \log_c m$ . $\begin{aligned} \log\left[ -\frac{1}{2\ln(0.5)}\right] & = \log\left[0.5^{2x}\right] \\ \log\left[ -\frac{1}{2\ln(0.5)}\right] & = 2x \log(0.5) \\ \dfrac{\log\left[ -\frac{1}{2\ln(0.5)}\right]}{2\log(0.5)} & = x \\ x & \approx 0.2356 \end{aligned}$ so the x-coord of the point of tangency is $x \approx 0.2356$ .the y-coordinate of this point of tangency can be calculated using the original function: $\begin{aligned} f(x) & = (0.5)^{2x} \\ f(0.2356) & = (0.5)^{2 \cdot 0.2356} \\ & \approx 0.7213 \end{aligned}$ using point-slope form, the equation of the tangent line is $y - 0.7213 = -1(x-0.2356)$ the x-intercept of this tangent line is when the graph is at y=0. $\begin{aligned} 0 - 0.7213 & = -1(x-0.2356)\\ - 0.7213 & = -(x-0.2356) \\ 0.7213 & = x-0.2356\\ x & = 0.9569 \end{aligned}$ this rounds off to $x & = 0.957$ .choice c.

Which statement describes absolute and apparent brightness? absolute brightness and apparent brightness are identical ways to describe the brightness of a star. absolute brightness and apparent brightness change with the distance from the star to the observer. absolute brightness depends on the distance from the star to the observer, whereas apparent brightness is always the same. absolute brightness is the actual amount of light produced by the star, whereas apparent brightness changes with distance from the observer.
