Consider vectors u and v, where u = (1, -1) and v = (1, 1). What is the measure of the angle between the vectors?

I believe the answer is C. 90 degrees

Step-by-step explanation:

First you find the lengths of the two vectors, which are both . Then you find the angle given the cos using:   cos(∅)= = = 0. Then using ∅=acos(0)= = 90°

two data sets with the same median will not have the same varaibility

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
