Answer:

Option (3)

Step-by-step explanation:

From the picture attached,

Bar graph sketched shows the grades earned by the students in an exam.

Number of students who achieved the grade A = 17

Number of students who achieved grade B = 14

Number of students with grade C = 5

Number of students with grade D = 9

Total students who took the exam = 17 + 14 + 5 + 9 = 45

Option (1)

"\frac{1}{5} of the students earned a C"

Fraction of students who earned C = \frac{\text{Students who earned C}}{\text{Total students}}

                                                          = \frac{5}{45}

                                                          = \frac{1}{9}

Therefore, this option is incorrect.

Option (2)

"3% more students earned an A then B"

Percentage of students who earned A = \frac{\text{Students got A}}{\text{Total students who took the exam}}\times 100

                                                                = \frac{17}{45}\times 100

                                                                = 37.78%

Percentage of students who earned B = \frac{\text{Students got B}}{\text{Total students who took the exam}}\times 100

                                                                = \frac{14}{45}\times 100

                                                                = 31.11%

Difference in percentage = 37.78 - 31.11

                                          = 6.67%

Therefore, this option is not correct.

Option (3)

"20% of the students earned a D"

Percentage of students who earned D = \frac{\text{Students got D}}{\text{Total students who took the exam}}\times 100

                                                                 = \frac{9}{45}\times 100

                                                                 = 20%

Option (3) is the correct option.

Option (4)

" \frac{1}{4} of the class earned a B"

Fraction of class who earned B = \frac{\text{Students got B}}{\text{Total students who took the exam}}

                                                    = \frac{14}{45}

Therefore, Option (4) is not correct.

After a bride has interviewed 7 DJs to play at her wedding, her fiance tells her she needs to narrow it down to 4 DJs. In how ma
Alex17521 [72]

Answer:

840

Step-by-step explanation:

Given

DJs = 7

To\ pick = 4

Required

Determine the number of rankings

The term "ranking" as used in this question implies permutation and the required is calculated using:

^nP_r = \frac{n!}{(n-r)!}

Where

n = 7

r = 4

So:

^nP_r = \frac{n!}{(n-r)!}

^7P_4 = \frac{7!}{(7-4)!}

^7P_4 = \frac{7!}{3!}

^7P_4 = \frac{7 * 6 * 5 * 4 * 3!}{3!}

^7P_4 = 7 * 6 * 5 * 4

^7P_4 = 840

<em>Hence, number of ranking is 840</em>
