The monthly income of 5,000 workers at the Microsoft plant are distributed normally. Suppose the mean monthly income is $3,250 and the standard deviation is $750. a) 10% of workers earn more than how much per month?

b) What percentile is a worker who earns $4050 per month?

c) What percentage of the workers earn between $3000 and $4500 per month?

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

u

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

answer: x=60
