The answer to this question is the first item in the choices which is "The teacher should use the mean for both Amo and Javier" when computing and comparing their grades. The mean is the average grade while the median is the center of the grade. It would be wrong to apply median in computing their grades and it would be also wrong when the use two different methods when computing and comparing their grades.

Space Shuttle Marion is observing the launch of a space

Vera_Pavlovna [14]

Using the slope concept, it is found that the shuttle traveled 3.2 miles while Marion was watching.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.

Initially, the angle of elevation is of 16º, with an elevation of 1 mi, hence:

$\tan{16^\circ} = \frac{1}{x_1}$

$x_1 = \frac{1}{\tan{16^\circ}}$

$x_1 = 3.5$

Then, at the end, the angle will be of 74º, with the elevation remaining constant, hence:

$\tan{74^\circ} = \frac{1}{x_2}$

$x_2 = \frac{1}{\tan{74^\circ}}$

$x_2 = 0.3$

The distance is:

$d = x_1 - x_2 = 3.5 - 0.3 = 3.2$

The shuttle traveled 3.2 miles while Marion was watching.

Is 1 5/8 greater than, less than, or equal to 1.6?

tigry1 [53]

Answer:

$1 \frac{5}{8} > 1.6$

Step-by-step explanation:

$1 \frac{5}{8} \: ... \: 1.6$

$\frac{1 \times 8 + 5}{8} \: ... \: 1.6$

$\frac{8 + 5}{8} \: ... \: 1.6$

$\frac{13}{8} \: ... \: 1.6$

$\frac{13}{8} \: ... \: \frac{16}{10}$

$\frac{13 \times 5}{8 \times 5} \: ... \: \frac{16 \times 4}{10 \times 4}$

$\frac{65}{40} \: ... \: \frac{64}{40}$

$\frac{65}{40} > \frac{64}{40}$
