Answer:
I think the answer is -8+-4=-12
Answer:
a) 3 kilograms
b) 5.7 kilograms
Step-by-step explanation:
Z-score:
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
We have to find X for both values of Z.
a) z = -1.35
3 kilograms
b) z = 2.64
5.7 kilograms
The total is 13.5 if that is what youre looking for
8,000 kilograms = 8000000 grams
