An arc on a circle measures 295°. the measure of the central angle, in radians, is within which range? a. 0 to π/2 radians b. π/2 to π radians c. π to 3π/2 radians d. 3π/2 to 2π radians

3π/2 to 2π radians.

D is the correct option.

Step-by-step explanation:

We know the relation between degree and radian.

180° = π radian

We'll use this relation to find the corresponding angle is radians.

295° should be equal to

Among the given options, this angle lies in the range 3π/2 to 2π radians.

D is the correct option.

the perimeter is increased by a factor of 2

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.
