The formula tells you
.. V = constant * T/P
That is, volume is proportional to absolute temperature and inversely proportional to pressure.
When temperature increases from 273 K to 300 K, volume is increased by the factor 300/273.
When pressure increases from 2 atm to 3 atm, volume is changed by the factor 2/3.
The new volume will be
.. (10 L) * (300/273) * (2/3) = 2000/273 L ≈ 7.3 L
Katelyn does not have enough money to buy items she likes.
Step-by-step explanation:
Amount Katelyn had = $205
Price of one sweater = $48
Price of 2 sweaters = 2*48 = $96
Price of one pair of pants = $34
Price of four pairs of pants = 34*4 = $136
Total price = Price of sweaters + price of pairs of pants
Total price = 
Sales tax = 6.5%
Sales tax = 
Total amount = Total amount of items + sales tax
Total amount = 232 + 15.08
Total amount = 247.08 Dollars
Therefore,
Katelyn does not have enough money to buy items she likes.

Answer:
Step-by-step explanation:
We want to determine a 95% confidence interval for the mean total cholesterol level of all males.
Number of sample, n = 355
Mean, u = 185 mg
Standard deviation, s = 16
For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean +/- z ×standard deviation/√n
It becomes
185 +/- 1.96 × 16/√355
= 185 +/- 1.96 × 0.849
= 185 +/- 1.66404
The lower end of the confidence interval is 185 - 1.66404 =183.336
The upper end of the confidence interval is 185 + 1.66404 = 186.66
Therefore, with 95% confidence interval, the mean total cholesterol level of all males is between 183.336 mg and 186.66 mg
Radius is MN
Cord is TR
