Answer:19
Step-by-step explanation:
7x3=21
21-2=19
8 shoes. each pair has 8!
The hour has stayed the same. 36-22 is 14. That's 14 minutes between.
Y=2(-1)^2-6(-1)+3
y=2+6+3
y=8+3
y=11
The probability is 0.2743.
Calculating the z-score for this time, we have:
z = (X-μ)/σ
z = (96-90)/10 = 6/10 = 0.6
Using a z-table (http://www.z-table.com) we see that the area to the left of this, less than this score, is 0.7257. This means the area greater than this would be 1-0.7257 = 0.2743.
