Hi there! To find the slope of the line, you do y2 - y1 / x2 - x1. That means you subtract the first y-coordinate from the second y-coordinate and the first x-coordinate from the second x-coordinate. Plug in the values in order to get 6 - 8 / 4 - 8. When you do that, you get -2/-4 or simply 1/2 when simplified. The slope of the line that goes through those points is 1/2.
No, it does not. You have to substitute -2 in for x and 3 in for y, and when you solve, you find that -2 + 2= 0, not 3z
Answer:
9n - 8
Step-by-step explanation:
The sequence is arithmetic since the difference between consecutive terms is common
d = 10 - 1 = 19 - 10 = 28 - 19 = 9
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 1 and d = 9, thus
= 1 + 9(n - 1) = 1 + 9n - 9 = 9n - 8, hence
= 9n - 8
Answer:
Stratified random sampling is based on a subdivision of the sample framework into strata with the help of an observable variable that separates them. After forming the strata, each individual is located in one and only one stratum. The sample is established by selecting a certain number of individuals in each stratum, guaranteeing a contribution of each stratum in the information obtained.
The best sampling method, in this case, is Stratified Random.
