Answer: 0.1974
Step-by-step explanation:
z1 = (12.9 - 16.3)/2 = (-3.4)/2 = -1.7
Z2 = (14.9 - 16.3)/2 = (-1.4/2) = -0.7
“Z table”
Z1= -1.7 ~ 0.0446
Z2 = -0.7 ~ 0.242
0.2420 - 0.0446= 0.1974
Answer:
B - 600 words in 12 minutes
Step-by-step explanation:
So most of this has to do with division. So let's look at answer one
320 words in 8 mins
320/8 = 40 words per minute.
600 words in 12 minutes
600/12 = 50 words per minute
350 words in 8 minutes
350/8 = 35 words per minute
And finally, 225 words in 5 minutes
225/5 = 45 words per minute. Thus, the answer is B
