The standard normal curve shown below is a probability density curve for a continuous random variable. This means that the area underneath the entire
curve is 1. What is the area of the shaded region between the two z-scores
indicated in the diagram?

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

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.

c - they will have the same distribution

this is the only one that could make sense. : )
