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.
Step-by-step explanation:
Well when you simplify it you get this,
0=-24,
Do what’s inside the parentheses first
3-3 is 0, 3•0 is 0
2•positive 3 is 6
6- -30 is -24
So you have 0=-24
Or just -24 :)
Angle: x
complement: 90-x
3x=90-x-14
4x=76
x = 19
90-x= 71
SOMEONE PLEASE HELP ME ) A central angle in a circle has a measure of 1 radian. The length of the arc it intercepts is 3.07 in. What is the radius of the circle?
Number of red marbles/total number of marbles
35/(35+8+7)
