Answer:
The answer is "Option a, Option b, and Option d".
Step-by-step explanation:
In the given question it is used to stratifying the sampling if the population of this scenario it flights takes off when it is divided via some strata.
-
In option a, In this case, it stratified the sampling, as the population of planes taking off has been divided into the days of the week.
-
In option b, It also used as the case of stratified sampling.
-
In options c, it is systematic sampling, that's why it is wrong.
-
In option d, It is an example of stratifying the sampling.
Albert bought 2 pounds of catfish and 2 pounds of salmon
Let c represent the amount of catfish in pounds and s represent the amount of salmon in pounds.
He spent a total of $12 on salmon and catfish and bought a total of 4 pounds. Hence:
c + s = 4 (1)
4c + 2s = 12 (2)
Solving equations 1 and 2 simultaneously gives:
c = 2, s = 2

Answer:
60.0735651 degrees
Step-by-step explanation:
So the hypotenuse is 50 and the vertical leg is 13
For the angle, you need to find the sine (opposite and hypotenuse)
sin(x) = 13/50
x = asin(13/50)
x = 60.0735651
Answer:
5
Step-by-step explanation:
Add the given numbers to the last recorded temp and see what is closest to 100 degrees.
95.5 + 6.5 = 101.5
95.5 + 6.6 = 102.1
95.5 + 5.5 = 101
95.5 + 5 = 100.5
So the closest to 100 degrees would be 5.
N - 5 ≥ -2
5 - 5 ≥ -2
5 - 5 = 0
n = 5
5 - 5 ≥ -2
5 - 5 = 0
(0 ≥ -2)
