Answer:
yeah sure
Step-by-step explanation:
because I'm friendly
I = 8.
k = 4
j = sqrt(8^2 + 4^2) = 8.944.
3 square root is called cube root btw:
cube root of -27/64 is the same as (cube root of -27)/(cube root of 64)
cube root of -27 is -3
cube root of 64 is 4
the anser is -3/4
Answer:
Step-by-step explanation:
Step-by-step explanation:
Let,
Marks in fourth test = x
We know that
Mean = Sum of observation/Total observation
=> 46 = Sum/3
=> 46 × 3 = Sum
=> 138 = Sum
Now,
=> 50 = Sum of three observation + x/4
=> 50 = 138 + x/4
=> 50 × 4 = 138 + x
=> 200 = 138 + x
=> 200 - 138 = x
=> 62 = x
Hence,
he should score 62 marks in fourth test
