<u>Value of</u><u> </u><u>x</u><u> </u><u>is</u><u> </u><u>3</u><u>0</u><u>°</u>
Answer:
Solution given:
x°+(5x)°=180°[being straight line which sum of angle is 180°]
adding like terms
(6x)°=180°
dividing both side by 6
(6x)°/6=180°/6
x=30°
Answer:
360 learners
Step-by-step explanation:
One way to solve these types of problems is that you could set up a proportion
learners/teachers = learners/teachers
Let x = no. of learners to enrol
30/1 = x/12
12(30) = x
x = 360 learners

i found it by dividing the value of G on 2
Answer:
Yes
Step-by-step explanation:
Given that In my data set of 10 exam scores, the mean turned out to be the score of the person with the third highest grade.
No two people got the same score.
Let the scores be a,b,c,d,e in ascending order where no two scores are equal
If a+b=d+e =2c then we can have c as the mean of the scores of 5 persons
This is because
Total sum = a+b+c+d+e = (a+b)+c+(d+e)
= 2c+c+2c=5c
Average= 5c/5 = c
It makes sense and there are chances as long as the above condition is satisfied.
1. C
2. A
3. B
3. D
