D. 8/17

Step-by-step explanation:

Applying

cos∅ = adjacent(a)/hypotenuse(h)

Where cos∅ = cosine of ∅, a = adjacent, h = hypotenuse

cos∅ = a/h Equation 1

From the diagram,

Given: ∅ = 62°, o = 8, h = 17

Substitute these values into equation 1

cos62° = 8/17

Hence the cosine of 62° has an eqivalent of of 8/17

From the question, The right option is D. 8/17

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean = $\frac{2+3+4+5+6+7+8+9}{8}=\frac{44}{8}=5.5$

also, median= $\frac{5+6}{2}=\frac{11}{2}=5.5$ , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean = $\frac{2+3+4+5+6}{5}=\frac{20}{5}=4$

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

in the opening of the question the word 'service' is associated only with the pretax value.

the closing part of the question asks: how much did she pay for the
