The following sample data shows the starting salaries of six graduates from the accounting program at California Polytechnic State University. The data are in thousands of dollars. 24 46 48 52 56 58 60 a. Calculate and interpret the 25th, 50th, and 75th percentiles. b. Are there any outliers? Is the distribution symmetric? If not, comment on its skewness.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

just sum

10 + 10 = 20

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
