Dwayne and Alisha both correctly graphed a standard normal curve. Which of the following statements is true? Neither the means nor the standard deviations of Dwayne’s and Alisha’s graphs must be the same. The means of Dwayne’s and Alisha’s graphs must be the same but not the standard deviations. The standard deviations of Dwayne’s and Alisha’s graphs must be the same but not the means. Both the means and the standard deviations of Dwayne’s and Alisha’s graphs must be the same.

Both the means and the standard deviations of Dwayne’s and Alisha’s graphs must be the same.

Step-by-step explanation:

The last one is correct:  Both the means and the standard deviations of Dwayne’s and Alisha’s graphs must be the same.

Step-by-step explanation:

Just took the test

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
