Weekly income = 70...she budgets 40 for movies and food.....70 - 40 = 30...that leaves 30 per week that she saves.
1 month = 4 weeks....so 6 months = (6 * 4) = 24 weeks
24 weeks....saving 30 per week = (24 * 30) = $ 720 <===
Answer:
A) (0,5)
Step-by-step explanation:
Coordinate point (0,5) lies within the bounded blue region
The difference between 81 and the mean is
81 - 74 = 7
This is exactly the value of the standard deviation. You know that the "empirical rule" tells you 68% of all scores lie within 1 standard deviation of the mean. That tells you 32% of all scores lie beyond 1 standard deviation from the mean.
The normal distribution is symmetrical, so half of those (16%) lie above 1 standard deviation above the mean; the other half (16%) lie below 1 standard deviation below the mean. We're only concerned with the first group—those scores above 1 standard deviation above the mean.
The appropriate choice is
D. 16%
Answer:
6 weeks
Step-by-step explanation:
At $200/week instead of $150/week, Nina's saving rate is 200/150 = 4/3 times the original rate. The time to save a given amount is inversely proportional to the saving rate, so it will take 3/4 of the time when Nina saves at the higher rate.
(3/4)(8 weeks) = 6 weeks
At $200 per week, it will take Nina 6 weeks to save enough for her vacation.
