Answer:

a.  113/338

b. The relative frequency distribution is presented as follows;

{}                                      St. John's wort              Zoloft                 Placebo

Full response {}               27/91                             27/91                  37/91

Partial response {}           16/55                             26/55                13/55

No response {}                35/96                            7/24                    11/32

c. 29.67%

Step-by-step explanation:

a. The proportion of subjects assigned to take St. John wort is found as follows;

The total number of subjects = 27 + 27 + 37 + 16 + 26 + 13 + 70 + 56 + 66 = 338 subjects

The number of subjects assigned to take St. John wort = 27 + 16 + 70 =  113

The proportion of subjects assigned to take St. John wort = 113/338

b. The distribution of change in depression response using relative frequency is found as follows;

Total full response = 27 + 27 + 37 = 91

Total partial response = 16 + 26 + 13 = 55

No response = 70 + 56 + 66 = 192

{}                                      St. John's wort              Zoloft                 Placebo

Full response {}               27/91                             27/91                  37/91

Partial response {}           16/55                             26/55                13/55

No response {}                35/96                            7/24                    11/32

c. The percentage of subjects that took Zoloft and showed full response is given as follows;

The percentage of subjects that took Zoloft and showed full response = 27/91 × 100 = 29.67%

Answer:

A. f + y ≤ 11

17f + 287 ≤ 242

Step-by-step explanation:

[] Let <em>f</em> be football players and <em>v</em> be volleyball players.

-> The total time must be less than or equal to 242 seconds.

-> If football players talked for 17 seconds, we can write it as 17f.

-> If volleyball players talked for 28 seconds, we can write it as 28v.

[] Coming back to the first point I made, the total time must be less than or equal to 242 seconds.

-> 17f + 28v ≤ 242

[] This is going to be a part of our system of inequalities

-> Because of this, we rule out the following options.

B & D - the football players talk for 17 seconds, not the volleyball players

C ​ - not less than or equal too, only less than

[] This leaves us with the option of A.

-> The first part of it also works. If 11 players can talk to the crowd, then the total of f and v must be equal too or less than 11.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

BRAINLIEST for the correct answer!
Vladimir [108]

Answer:

answer is A

Step-by-step explanation:

(3x^{2}+5x+1) (x^{2}−2x+4)

=(3x^{2}+5x+1)(x^{2}+−2x+4)

=(3x^{2})(x^{2})+(3x^{2})(−2x)+(3x^{2})(4)+(5x)(x^{2})+(5x)(−2x)+(5x)(4)+(1)(x^{2})+(1)(−2x)+(1)(4)

=3x^{4}−6x^{3}+12x^{2}+5x^{3}−10x^{2}+20x+x^{2}−2x+4

=3x^{4} − x^{3} + 3x^{2} + 18x +4
