Answer:
Y = 6 and x=6 are perpendicular because they both measure at a 90 degree angle
Answer:
Step-by-step explanation:
Hello!
You have the information for two variables
X₁: Number of consumer purchases in France that were made with cash, in a sample of 120.
n₁= 120 consumer purchases
x₁= 48 cash purchases
p'₁= 48/120= 0.4
X₂: Number of consumer purchases in the US that were made with cash, in a sample of 55.
n₂= 55 consumer purchases
x₂= 24 cash purchases
p'₂= 24/55= 0.4364
You need to construct a 90% CI for the difference of proportions p₁-p₂
Using the central limit theorem you can approximate the distribution of both sample proportions p'₁ and p'₂ to normal, so the statistic to use to estimate the difference of proportions is an approximate standard normal:
[(p'₁-p'₂) ±
*
]

[(0.4-0.4364)±1.648 *
]
[-0.1689;0.0961]
The interval has a negative bond, it is ok, keep in mind that even tough proportions take values between 0 and 1, in this case, the confidence interval estimates the difference between the two proportions. It is valid for one of the bonds or the two bonds of the CI for the difference between population proportions to be negative.
I hope this helps!
242mg
Explanation:
You would create a ratio for this situation
3oz/22mg=33oz/x
So we know 3*11=33 so we would do 22*11 and get 242 mg
Answer:
Option C
Step-by-step explanation:
Option D's unit is not used in volume measurement. A "ton" is 2,000 lbs. Pounds are not used to measure volume.
Since we are looking at the volume of a "large tank", then a quart and a pint would be too small, and therefore, not the most appropriate units to measure the volume of the tank with.
A "kiloliter" is equivalent to 1,000 liters. Note that the prefix "Kilo-" means 1,000. A kiloliter would be appropriate for measuring the volume of a large object, in this case a oil tank. It is the most appropriate out of the options given.
Option C should be the correct answer.
