Expression 1:
-12x4 + 7x3 + 6x4 - 2x3
x4 (-12 + 6) + x3 (7-2)
-6x4 + 5x3
Answer:
5x ^ 3 - 6x ^ 4
Expression 2:
-5x3 + 7x4 + 4x4 - 8x3
x4 (7 + 4) + x3 (-5-8)
11x4 - 13x3
Answer:
11x ^ 4 - 13x ^ 3
Expression 3:
-2x4 - 10x3 + 4x4 - 2x3
x4 (-2 + 4) + x3 (-10-2)
2x4 - 12x3
Answer:
2x ^ 4 - 12x ^ 3
Expression 4:
15x3 - 15x4 + 13x4 - x3
x4 (-15 + 13) + x3 (15-1)
-2x4 + 14x3
Answer:
14x ^ 3 - 2x ^ 4
Expression 5:
7x4 - 15x3 + 12x3 - 2x4
x4 (7 - 2) + x3 (-15 + 12)
5x4 - 3x3
Answer:
5x ^ 4 - 3x ^ 3</span>

Answer:
0.5 = 50% of bottles have volumes less than 1,007 mL
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
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 that:
What proportion of bottles have volumes less than 1,007 mL?
This is the pvalue of Z when X = 1007. So
has a pvalue of 0.5
0.5 = 50% of bottles have volumes less than 1,007 mL
