Answer:

45.45 batteries

Step-by-step explanation:

The probability of any random battery being defective is 1 in 11, the number of expected defects in a population of 500 batteries is given by:

E= \frac{1}{11}*500\\E=45.45\ batteries

45.45 batteries are expected to be defective.

For this case we have the following inequality:
 - \frac{1}{2}x \ \textgreater \  6
 We multiply both sides of the equation by -1.
 By doing this, change the symbol of the inequality.
 We have then:
 \frac{1}{2}x\ \textless \ -6
 From here, we clear the value of x.
 We have then:
 x \ \textless \ (2) (- 6)

 x \ \textless \ -12
 
 Answer:
 The solution set is:
 
{x | x R, x < -12}

The spinner for a board game has eight colors the arrow can land on. What are the degrees of freedom for a goodness-of-fit test
Juliette [100K]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Number of colors that the arrow can land on = 8

We need to find the degrees of freedom for a goodness of fit test of the fairness of this spinner.

As we know that degree of freedom is 1 less than the size of sample.

So, Mathematically, it is expressed as below:

So, Degree of freedom would be

v=n-1\\\\v=8-1\\\\v=7

Hence, Option 'c' is correct.
