then finally divide -3 from -45 to get x=15
Answer:
Step-by-step explanation:
Looking at the information given, the average or mean lowest prices and standard deviations for the two cities are given. The standard deviation is a measure of variability. It is used to determine how far the values in the data are from the mean. A lower standard deviation means that the values are closer to the mean. A higher standard deviation means that the values are farther from the mean.
Since 0.07 is lower than 0.23, the correct statement that is true about their gas-price data is
Raquel's data are most likely closer to $3.42 than Van's data are to $3.78.
Answer:

(1)
(2)
Where R is for Reagan and N for Nathan.
Knowing that:
By adding equations (1) and (2) we have:
Therefore, they meet in 2.22 hours.
