Since the average is <numbers combined> over <number of numbers>, we have 4+1=5 numbers (tests) and 92+91+94+79+x=356+x, resulting in
(356+x)/5=90. Multiplying both sides by 5, we get 356+x=450 and by subtracting 356 from both sides we get x=94 as the minimum score
4×6817=27256 so it is 27 thousand
Answer:
-(-3) ± √(-3)^2 - 4(2)(-5) / 2(2) (the last choice).
Step-by-step explanation:
Im ignoring the 2^2 in the equation
The equation transforms to
2x^2 - 3x - 5 = 0 (standard form)
So x = -(-3) ± √(-3)^2 - 4(2)(-5) / 2(2)
Answer:
if the X is equal and large than 5 The X would be 5 or the any numbers large than it :)
