Answer:
√7x−49√x
Explanation:
First of all, expand by multiplying √7x⋅√x and √7x⋅7√7respectively:
√7x(√x−7√7)=√7x⋅√x−√7x⋅7√7
... you can express √7x as √7⋅√x...
=√7⋅√x⋅√x−√7⋅√x⋅7⋅√7
=√7⋅(√x)2−(√7)2⋅√x⋅7
... the operations squaring and taking the square root "eliminate each other"...
=√7⋅x−7⋅√x⋅7
=√7x−49√x
Hope that this helped!
Answer: 
Step-by-step explanation:
Given : The probability of a correct classification of any part is : p=0.96
sample size : n= 3
The formula to find the mean and variance for binomial distribution is given by :-
Let the random variable X denote the number of parts that are correctly classified.
The, for the given situation, we have
Hence, the mean and variance of X are 2.88 and 0.115 respectively.
Answer:
Answer C is the only one in function notation.
Step-by-step explanation:
To find something in function notation, we look for 2 different criteria.
- On the left side, it must say f( ), with a variable in the parenthesis.
- On the right side, the variable being used must match that from the left side.
Since C is the only one that satisfies both of those needs, we know it is the answer.
