Convert x=20.5 to a z score. (recall z = (x-mean)/standard deviation) -2.73
-2.80
-2.93
-3.01

answer: t=3

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.
