(x) = x
g(x) = -
A. g(x) = (x+4)2 - 2

D. g(x) = (x+4)2 + 2

The final question is;

Why is it not appropriate to calculate a two-sample z-interval for a difference in proportions?

Answer:

The normality of the sampling distribution of the difference in sample proportions cannot be established.

Step-by-step explanation:

To use the two-sample z-interval for a difference in proportions, some conditions must be met which help us to know the normality of the distribution.

The conditions are;

- The method of sampling for each population must be simple random sampling.

- The samples must be independent.

- Each sample must include at least 10 successes and 10 failures.

- Each population must be a minimum 20 times its sample.

In this case, we are not given the population size and as such we cannot ascertain the last condition I wrote above since the sample proportion we are given alone isn't sufficient. Also, they both don't include at least 10 failures. Thus the normality of the sample proportions cannot be established.

Answer: the normality of the sampling distribution of the difference in sample proportions cannot be established

Step-by-step explanation:

The number of footballs that are for sales when its known that there are total 318 footballs and basketballs and there are 76 more footballs for sale than basketballs, is given by: Option C: 197

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

Given that:

Assume that:

Then we get two equations, as:

[tex]x+y = 318\\x = 76 + y[/tex]

Substituting the variable x in first equation by the expression obtained in second equation for x, we get:

[tex]x + y = 318\\(76 + y) + y = 318\\76 + 2y = 318\\\text{Subtracting 76 from both the sides}\\\\2y = 318 - 76 = 242\\\\\\2y = 242\\\\\text{Dividing both the sides by 2}\\\\y = \dfrac{242}{2} = 121[/tex]

Thus, we got: Number of basketballs  = y = 121

Using this result and the first equation, we get:

[tex]x + 121 = 318\\x = 318 - 121 = 197[/tex] = number of footballs.

Thus, the number of footballs that are for sales when its known that there are total 318 footballs and basketballs and there are 76 more footballs for sale than basketballs, is given by: Option C: 197

Answer:

C. 3

Step-by-step explanation:

Prime Factorization of 6:  2 × 3

Prime Factorization of 21:  3 × 7

Common Factors of 6 and 21: 3

So the greatest common factor of 6 and 21 is 3, that is, GCF of 6 and 21 is 3.
