A set of n = 5 pairs of x and y scores has σx = 15, σy = 5, and σxy = 10. for these data, what is the value of sp?

Match each equation with the operation you can use to solve for the variable. subtract 10. divide by 10. divide by 5. subtract 18. multiply by 10. add 18. add 10. multiply by 5. 5 = 10p arrowright p + 10 = 18 arrowright p + 18 = 5 arrowright 5p = 10 arrowright

The parabola x= √y-9 opens: a.)up b.)down c.)right d.)left

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).
