8 batches in an hour
Step-by-step explanation:
2 in 1/4
2 × 4 = 8
Answer:
here's an example i found
Step-by-step explanation:
The Central Limit Theorem for Sums states that the mean of the normal distribution of sums is equal to the mean of the original distribution times the number of samples, so the mean is (280)(42)=11760. The standard deviation is equal to the original standard deviation multiplied by the square root of the sample size. So, the standard deviation is (12)(42−−√)≈77.769. To find the probability using the Standard Normal Table, we find that the z-scores for the two values, 11815 and 11840, are 0.71 and 1.03 respectively, using the formula z=x−μσ. Using the Standard Normal Table, the area to the left of z=0.71 is 0.7611, and the area to the left of z=1.03 is 0.8485. 0.8485−0.7611=0.0874, so the probability is about 9%.
To find the probability using a calculator, we can put the values into the normalcdf() function as: normalcdf(11815, 11840, 11760, 1242−−√), which gives us a result of 0.0879.
Step-by-step explanation:
Question 8)
2,8,14
d=a2-a1
d=8-2=6
a77= 2+ (76)*6
a77= 2+456=458
a77= 458
Question 9)
-12,-17,-22
d= -17+12= -5
a82= -12+ (81)*(-5)= -12-405= 417
a82= 417
Question 10)
9,13,17
d= 13-9= 4
a49= 9+ (48)*4= 201
a49= 201
So he started with 3/4 lb and ended up with 2/3 of that so 2/3 of 3/4
'of' can be roughly translated as multiply
so 2/3 times 3/4 =6/12=1/2 lb left
or you know that there are 3 out of 4 parts pound left so 2 out of 3 parts of nuts is = 2/4 or 1/2 lb
