Step-by-step explanation:
5×10³) × (9×10^7)
= 45 × 10^10
= 4.5 × 10¹¹
Solve what is in parenthesis first (5-9) = -4
Solve exponents next -4^3 = -64
Divide next

= -32
Lastly, subtract and resolve the negatives which become a positive number 125 - (-32) = 125 + 32 = 157

Step-by-step explanation:
df denote degree of freedom
here in question it is given that eleven different video games showing
so here n=11
we know that for calculation of degree of freedom
we can calculate degree of freedom if the sample size n is given degree of freedom is 1 less than sample space
so degree of freedom = sample size -1 =11-1 =10
so the value of degree of freedom that is df is 10
