Which function best fits the following points?
1 answer:
Answer:
Correct answer is choice B.
Step-by-step explanation:
We have been given a graph and 4 different choices.
Now we need to determine about which of the given functions best fits the points in the graph.
From graph we can clearly see that points are going upward very fast as compared to x when x-value increases.
That happens in exponential type function which is usually written in form of
Choice B looks similar to that.
hence correct answer is choice B.

Answer: It is not enough evidence to support the researcher's claim.
Step-by-step explanation:
Since we have given that
n = 500
So, the hypothesis are as follows:
So, the z value would be
At α = 0.05
z= -1.64
So, 1.64<-1.33
So, we accept the null hypothesis.
Hence, it is not enough evidence to support the researcher's claim.
Alright, lets get started.
Sophie has 5 pieces of string that are 4 yards each.
1 yards = 3 feet,
So, 4 yards = feet
Total number of string she has = 5 piece
So, total length she has = feet
It means she had 60 feet string in starting.
Now, She uses 3 pieces that are each 3 feet long, means
She uses = feet
So, remaining string length will be = feet
Means 51 feet string does Sophie have. : Answer
Hope it will help :)
