Use the diagram of the right triangle above and round your answer to the nearest hundredth.

Yakvenalex [24]

Answer: a = 23 ft.

Reasoning:

The question asks for the value of the leg a, given the tangent of the opposite angle and the length of the adjacent-leg, b.

The ratio that relates the three parameters is:

tan(A) = opposite-leg / adjacent-leg = a / b = a / 23 ft

Solve for a, wich is the unknown:

a = 23ft * tan(A) = 23ft * 1.0 = 23 ft

Answer: 23 ft.

Solnce55 [7]

So multiply 128 by 15 to get 1920 and then move the decimal over two places to get 19.20 and then subtract that $19.20 from $128 to get $108.8

The table shows the battery lives in hours of ten Brand A batteries and ten Brand B batteries.

Plotting the data (attached photo) roughly shows that the data is skewed to the left. In other words, data is skewed negatively and that the long tail will be on the negative side of the peak.

In such a scenario, interquartile range is normally the best measure to compare variations of data.

Therefore, the last option is the best for the data provided.
