Step-by-step explanation:
A=P(1+R)
A/P=1+R
(A/P)-1=r
(3000000/20000)-1=r
149=r
Answer:
Step-by-step explanation:
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
A. Getting recommended by a teacher
Step-by-step explanation:
Arithmetic mean formula is
A=(x1+x2+x3+....+xn)/n
in this case
A=(8+10+10+10+6+7+8)/7=
=59/7=
=8.42857143~=8.4
