Answer:
x = 12.7 or x ≈ 12
Step-by-step explanation:
1.75 + 0.65x = 10
0.65x = 10 - 1.75
0.65x = 8.25
x = 8.25 / 0.65
x = 12.7
x ≈ 12
note: we round it up to 12 and not 13, because Erica does not have enough money for 13 miles
Part of the question that is mission: SAT math scores have a bell-shaped distribution with a mean of 515 and a standard deviation of 114.
Solution:
For scores between 401 and 629 = (515-114 = 401) and (515+114 = 619). In other words, the range given is within 1 standard deviation.
Based on Empirical rule, 1 standard deviation represents approximately 68% thus 68% is percentage of SAT scores between 401 and 629.
