Answer:
x = 45.25 and 2x + 9.50 < 100
Step-by-step explanation:
Okay, so I dont know if you want am explanation but here I go
if for each game shipping is 4.75, you multiply by 2 to find the total there, hence 9.5.
and you dont want to go over $100, so the amount you spent has to be less then $100
and you're going to buy 2 games, x stands for the price.
2x + 9.50 < 100
2x < 90.5 (i just subtracted 9.5 on each side)
2/2x = 90.5/2
x = 45.25
Answer:
1.627 miles is the difference
Answer:
18000
Step-by-step explanation:
The average score is 500 points and the standard deviation is 50 points.Mean - 2 SD = 500 - 2 * 50 = 500 - 100 = 400It means that more than 400 on the standardized test is more than: Mean - 2 Standard deviations.For the Normal distribution: 100% - 2.5 % = 97.5% = 0.975.Answer: The probability that student scores more than 400 points is 0.975.
Given
This can be simplified as follows:
Option A is the correct answer.
