=13
Step-by-step explanation:
a2 + b2 = 5 2 + 12 2 = 13
Answer: 1.48
Step-by-step explanation:
From binomial distribution, the formula to find the standard deviation is given by :-
, where n is the sample size and p is the proportion of success.
Given : The percent of chance that a candle is defective. If the company selected 50 candles off the line : 4.6%
i.e. The proportion of success : p=0.046
Sample size : n=50
Then, Standard deviation =
Hence, the standard deviation of the number of defective candles in the group=1.48
Answer:
Option (C).
Step-by-step explanation:
In the graph attached,
An absolute function has been given.
To check a graph whether it's a relation or a function, vertical line test is a trusted tool.
In vertical line test a vertical line (parallel to y-axis) is drawn passing through the graph.
If the vertical line cuts the graph at only one point then the graph is said to be a function.
The given graph passes the vertical test.
Therefore, it's a function.
Option C. will be the answer.
