Answer:
Krishna's marks x marks
so...
xˉ=15
xˉ=15n=10
xˉ=15n=10∑x=x+x−8+x−6+x−3+x−1+x+x+2+x+3+x+4+x+6=10x−3
15=10x-3/10
150+3=10x
x=150/10=15.3 marks
<em><u>Krishna scored 15.3 marks.</u></em>

Answer:
yes
the sum of the squares of the width and length is equal to the square of the diagonal
Step-by-step explanation:
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
24^2 + 70^ = 576 + 4900 = 5476
square root = 74
Answer:
<u>8(n + 3) = 9</u>
Step-by-step explanation:
8
∨ × → ( n + 3) = 9
Eight times the sum of a number and 3 is 9
--------------------------------------------------------------------------------
8(n + 3) = 9
Step-by-step explanation:
subtract you squared from both sides
divide both sides by 2A
