<h2>Answer:</h2>

Maryam TOTAL percentage score for the exam is:

71%

<h2>Step-by-step explanation:</h2>

<u>Paper--1</u>

Total marks=120 marks.

The percent score scored by Maryam is: 65%

This means that the score scored by Maryam is: 0.65×120=78

<u>Paper--2</u>

Total marks=80

The percent score scored by Maryam is: 80%

This means that the score scored by Maryam is: 0.80×80=64

Hence, Total marks of both the paper are: 120+80=200 marks

Marks scored by Maryam in both the subjects is: 78+64=142 marks

Hence, Total percentage score for the exam is:

$=\dfrac{142}{200}\times 100\\\\\\=\dfrac{142}{2}\\\\\\=71\%$

Hence, her total percent score is:

71%

71 %

Calculate score for each paper, total them and convert to a percentage.

Paper 1 : mark = 0.65 × 120 =78

Paper 2 :mark = 0.8 ×80 = 64

Total mark = (78 + 64)/200 =142/200

Percentage score = 142/200 × 100 % = 71 %

There are 130 people in a sport centre. 73 people use the gym. 62 people use the swimming pool. 58 people use the track. 22 peop

Delvig [45]

Answer:

$\frac{11}{87}$

Step-by-step explanation:

Total number of people = 130

Number of people who use the gym = 73

Number of people who use the pool = 62

Number of people who use the track = 58

Number of people who use the gym and the pool = 22

Number of people who use the pool and the track = 29

Number of people who use the gym and the track = 25

Number of people who use all three facilities = 11

Total number of people who use at least two facilities = 22 + 29 + 25 + 11 = 87

The probability that the randomly selected person uses all three facilities = number of those who use all three facilities ÷ total number of people who use at least two facilities.

==> 11 ÷ 87

==> $\frac{11}{87}$
