Answer:
B. Multiplication or Division property of equality
Step-by-step explanation:
Both sides of the equation have been multiplied by -1. The multiplication property of equality tells you that multiplying both sides of the equation by the same number does not change the truth of the equation (and the variables retain their values).
I'm pretty sure your answer is 166. hope this helps

Answer:
0.3594 = 35.94% probability that a truck will weigh less than 14.3 tons
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Mean is 15.8 tons, with a standard deviation of the sample of 4.2 tons.
This means that 
What is probability that a truck will weigh less than 14.3 tons?
This is the pvalue of Z when X = 14.3. So



has a pvalue of 0.3594
0.3594 = 35.94% probability that a truck will weigh less than 14.3 tons
