Answer:

D.It is true because its domain of all real numbers  greater than or equal to -7 and less than 2.

Step-by-step explanation:

We have to find that graph which represent a function whose domain of all real numbers   :greater than or equal to -7 and less than 2.

A.Graph A does not represent that function because its domain of all real numbers greater than  -2 and  less than or equal to 7.It is not true.

B.Graph B does not represent that function because its domain  of all real numbers greater than or equal to -4 and less than 1.

C.It is not true of all real numbers because its domain of all real numbers  greater than or equal to -3 and less than 2.

D.It is true because its domain of all real numbers  greater than or equal to -7 and less than 2.

Hence, option D is true.

VARVARA [1.3K]

Answer:

The selections are dependent.

Yes, they can be treated as independent (less than 5% of the population).

Step-by-step explanation:

Since the selections are made without replacement, each selection affects the outcome of the next selection and, therefore, the selections are dependent.

Although they are dependent, the selections can be treated as independent if the sample size is no more than 5% of the total population. In this case, the sample size is 1235 adults out of a population of 15,958,866 adults. The percentage represented by the sample is:

P=\frac{12,345}{15,958.866}*100\\ P=0.077\%

Thus the selections can be treated as independent for the purposes of calculations.

r/ 2 + − 2r ⋅ 2/ 2 + 6 − 3

r − 2 r ⋅ 2 /2 + 6 ⋅ 2/ 2 + − 3 ⋅ 2/ 2

r − 2 r ⋅2 + 6⋅ 2 − 3 ⋅ 2 /2

r − 4 r + 12 − 6 /2

−3 ( r − 2 ) /2
