someone's first seven grades for the year are 91, 87, 80, 99, 85, 78, and 90. what grade is at the 75th percentile

The answer is here

Step-by-step explanation:

https://www.slader.com/discussion/question/the-following-scores-represent-the-final-examination-grades-for-an-elementary-statistics-course-23-6/

75th percentile means that 75% of the accepted students made a 1570 or below on the test and that 25% of the accepted students scored above a 1570.

S based on that I think it is 80 or 85

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!

-une, your fren : )

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
