First you must calculate the percentage that was increased. It was increased by 2 and 2 is 1/6 of 12 therefore you must add 1/6 to the potent flow as well .1/6 of 240 is 40 and 240+40=280
To solve this problem we use the z statistic. The formula
for z score is:
z = (x – u) / s
where,
x = sample value mean = 178 – 0.56 = 177.44 mm
u = total sample mean = 178 mm
s = standard deviation = 12 mm
z = (177.44 – 178) / 12
z = -0.05
from the tables P (z = -0.05) = 0.484
So the probability P is: [multiply by 2 since we account the two sides)
<span>P = (0.5 – 0.484) * 2 = 0.0320</span>
Answer:
2
-1
x=4,y=11 (same in both equations)
Total surface area: approximately 979.3 inches squared (total), 754.3 inches (lateral), and 225 inches (bottom)
