A physiology professor assigns letter grades on a test according to the following scheme: A: top 14% of scores B: Scores below the top 14% and above the bottom 65% C: scores below the top 35% and above the bottom 23% D: scores below the top 77% and above the bottom 5% F: bottom 5% of scores Scores on the test are normally distributed with a mean of 66.9 and a standard deviation of 7.9. Find the numerical limits for a B grade. Round your answers to the nearest whole number

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

thats not a system of equations, that is a solution
