I’m kinda confused by this question but
Hope that helped :)

Answer:
Step-by-step explanation:
Let x be the speed of Savanna's truck. ?Time taken to travel 300 miles = 300/x
Tony's car speed = distance/time 280/(x-2)
Given that Tony is faster than Savannaby 20 mph
i.e.
cancel 20 on both sides and simplify
x cannot be negative
so x = 6 hours
i.e. Speed of Savanna is 50 mph and speed of
Tony is 70 mph
Time taken for Savanna to travel 300 miles is 6 hrs while for Tony to travel 280 miles is 4 hours.

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 of 400 and a standard deviation of 60.
This means that
z=3
We have to find X when Z = 3. So
The data item is
Answer:
17
Step-by-step explanation:
12 1/2 -(-4 1/2) = 12 1/2 + 4 1/2
=25/2 + 9/2
= 34 /2
= 17
