A confidence interval tells us how many percents we are confident about the range of a parameter. In this problem, <span>a 95% confidence interval for the mean number of hours spent relaxing or pursuing activities they enjoy was (1.38, 1.92). That means we're 95% confident that the Americans spend from 1.38 hours to 1.92 hours per day on average relaxing or pursuing activities they enjoy. In other words, 95% of the samples of the same size would have a mean number of hours relaxing or pursuing activities they enjoy between 1.38 to 1.92.</span>
Answer:
x = 50.60 cm
Step-by-step explanation:
Given triangles ΔMAB and ΔMNP are smilar accordingly their corresponding sides are proportional.
But first we will determine the size of the side MA:
MA = MN - AN = 46.2 - 14 = 32.2 cm
Now we will make proportion:
MN : MA = MP : MB => 46.2 : 32.2 = 72.6 : x
When we multiply external and internal members we get:
46.2 x = 72.6 · 32.2 => x = 72.6 · 32.2 / 46.2 = 2337.72 / 46.2 = 50.60 cm
x = 50.60 cm

Well, without any prices, I can’t give you a number. And someone else may have a simpler way to do this.
But we’ll call the original bill x.
After the 10% off coupon, the bill is 0.9x
Adding tax = 0.07(0.9x) + 0.9x
Adding a tip = 0.20[0.07(0.9x) + 0.9x)]

He is not correct, any number 5 or greater rounds the number up.
The speed of the dragonfly would be 7 because 7 rounds 9 to 10 making 6 a 7.
