Nick surveyed a random sample of the freshman class of his high school to determine whether spring break should be in March or April 1990 students surveyed 26.6% preferred April. Based on this information about how many students and then to hire 230 person class would be expected to prefer having spring break in March?

91

Step-by-step explanation:  33.2 percent of a 275 person class is 91.3, and yoy round down because you can't have 0.3 of a person

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

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.
