Answer:
2nd Graph
Step-by-step explanation:
Bases off the graphs, you gave me, I assume your the equation is
The parent equation of this function is
Let say x=0
Using the rules of exponets, the y value must be 1 so a critical point is
(0,1)
The function is multiplied by -4.
This means the function is stretched in the y direction by 4 and reflected over the x axis. So our new point will be
(0,-4).
The base 2 the function will get compressed by 1/2.
The best graph that represents this is the second graph
Graph A because it has two stationary points. That is, if you differentiate and put dy/dx as 0 there will be two answers
2x - y = 1
2x + y = 7
-------------------add
4x = 8
x = 2
2x - y = 1
2(2) - y = 1
-y = -3
y = 3
answer (1,3)
Answer:
The element that you talked about is bromine
Answer: (B) Systematic
Step-by-step explanation:
(A) Random : In this researcher randomly selects individual from population to make sample.
(B) Systematic : It is a kind of random sampling method where researcher decide the starting point to select individual , then follow a systematic pattern to select them.
(C) Stratified : It is a kind of random sampling method where researcher divides the population into groups ( on the basis of characteristics) called as strata , then selects individuals from each strata.
(D) Cluster : It is a kind of random sampling method where researcher divides the population into groups known as clusters , then randomly selects clusters to include in sample.
(E) Simple random : It is a kind of random sampling method where researcher randomly selects individual from population to make sample.
Since , a random number is generated to determine a starting position in the list and then every tenth attendee is placed in the sample.
That means sponsors follow as systematic pattern.
Therefore , the methods was used to select the probability sample : (B) Systematic
