Answer:
0.4 to 1
Step-by-step explanation:
2 1/2=2.5
you do 1 divided by 2.5 or 1/2.5 and you get 0.4 then add the unit rate of 1.
Answer: magnitude ab = 9.06
Step-by-step explanation:
The vector coordinates will be represented with ( X , Y )
Magnitude of ab will be
ab^2 = (X2 -X1)^2 + (Y2 -Y1)^2
ab^2 = (2 -1)^2 + (-3 -6)^2
ab^2 = 1^2 + 9^2
ab^2 = 1 + 81
ab = 9.06
We first find A2, for which we multiply A with itself. We perform matrix multiplication in which we multiply rows of first matrix with columns of second matrix element by element and add.
Answer:
Stratified Sampling
Step-by-step explanation:
Since Keri divides the day into different strata and each unit is selected from each strata randomly. So, it is Stratified Sampling.
Further, In Stratified Sampling population is divided into several groups such that within the group it is homogeneous and between the group it is heterogeneous. And now a selection of each stratum and unit has an equal chance of selection.
