The salary of an employee is 500$ . Knowing that the annual raise of salary is 10 % . then his salary after 2 years is

using the formula of compound interest:

500*(1+(10/100)^2

500= money

1 = interest, so the multiplier has to  be above 1

10/100 = 0.10 + 1 = 1.1 = multiplier

^2= years

then we get

500  *(1.1)^2

1.1^2 = 1.21

=605

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 =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

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.

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
