Answer:
a) At the end of the bones
A^2+b^2=(a+b) (a-b)
Let a^2=x^2 then a^2= x^2
Let b^2=63 them b^2= 64
b=8
Answer: (x+8) (x-8)
Answer:
Step-by-step explanation:
The real part does not have i as a multiplier. It is 23.3.
The imaginary part* is the coefficient of i: 44.
_____
* There is some disagreement as to whether the imaginary part includes i or not. One source says the imaginary part is the part that has i as a factor (44i). Another source says the imaginary part is the real number that multiplies i (44). Above, we have used the latter definition. Please consult your curriculum materials for the definition you should use.
It is found that Margo will be using random sampling.
• Random sampling in statistics is a part of the sampling technique in which each sample has an equal probability of being chosen. In other words, a sample chosen randomly is an unbiased representation of the total population.
Sample strategies may be classified as :
1) Convenient : The sample which is drawn from a conveniently available pool.
2) Random : When all options are into a hat and draw some of team
3) Systematic : Every kth element
4) Cluster : When we divide population into groups called clusters, and each element os cluster is surveyed.
5) Stratified : In stratified also divides the population into groups, However only some of the elements of the group are surveyed.
According to the question
Marbles are taken from the bag, and after they are taken they are again placed back in the bag so it depicts Random Sampling.
