266 students.

1 question. What is the lowest total score in two subjects among students in the Northern District? Write your answer in cell G2.

Decision

    To cell E 2 write down formula 1 = if ( b 2=”Northern”;С2+ D 2;”-“)

    To cell G 2 write down formula2 = min ( E 2: E 267) . This is the answer to question 1.

2 question. What percentage of the total number of participants were students who received at least 65 percent in computer science.

Decision.

    In a cell H 2 write down formula 3, counting the number of students who received in computer science >=65 points = countif ( d 2: d 267;”>=65”) .

    Let's make a proportion

266 accounts 100%

H2 X%

from here

X=H2*100/266.

To cell G 4 write down formula 4 = H 2*100/266 . This is the answer to question 2.

3 question. What is the highest sum of points in two subjects among schoolchildren who received more than 50 points in physicsor computer science? Enter your answer in the boxG 6.

Decision

    To cell F 2 write down formula 5 = if ( or ( c 2>50; d 2>50);C2+ D 2;”-“) . The formula must be copied down for all students.

    To cell G 6 write down formula6 = max ( F 2: F 267) . This is the answer to question 3.

OR- or

AND- and

IF- if

= max () is the function of finding the maximum value

= min () - function of finding the minimum value

= countif (cell range;”condition”)– counting the number of cells for which some condition is met

= if (condition; action 1; action 2)- checking the condition, if it is true, action 1 is performed, if the condition is false, action 2 is performed.
