Answer:
See below
Step-by-step explanation:
1. Standard notation
4.2 × 10⁻⁴ m
A negative exponent indicates
- A number between 0 and 1.
- That the decimal point is shifted that number of places to the left.
4.2 × 10⁻⁴ tells you that the decimal number is 4.2, with the decimal point moved four places to the left.
The number becomes 0.000 42
.
2. Metres to millimetres
3. Measurements agree?
Yes, because both measurements are the same as 0.42 m.
4. More appropriate measurement
Most measurements should be expressed as a number between 0.1 and 1000, because most people aren’t particularly good at visualizing larger or smaller numbers.
Justin's measurement of 0.42 mm is more appropriate than Amanda's measurement of 4.2 × 10⁻⁴ m.
A baseball team scored the following number of runs in its games during the current season: 6, 2, 5, 9, 11, 4, 5, 8, 6, 7, 5. Th

Answer: 14 runs
Step-by-step explanation:
The average is the total number of runs divided by the number of games played. In order to work backwards to find the score of the final game, use this equation: <em>(final game score = (average * total number of games) - total runs of all games played so far) </em>
The total number of games in the season is 12. Multiply the average of 6 by 12 to find the total season score needed (6*12=72). Now add up the total number of runs from games 1-11 (6+2+5+9+11+4+5+8+6+7+5=58). Subtract this number from 72 to find the lowest possible score of the final game (72-58=14).
