Answer: 453
Step-by-step explanation:
To solve the question, we have to calculate the margin of error which will be:
= (61.7% - 52.3%) / 2
= 9.4% / 2
= 4.7%
4.7% = 1 / ✓n
0.047 = 1 / ✓n
✓n = 1 / 0.047
✓n = 21.28
Square both sides to.gwt the value of n
n = 21.28²
n = 452.69
n = 453

Answer:
D.) 4
Step-by-step explanation:
Your highest exponent is your degree.
Its easier if you put the polynomial in order:
27x^4+15x^3+63x+35
Answer:
y = 
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 
when x = 
, thus
= 
= 2k ( divide both sides by 2 )
k = 
y = 
← equation of variation
When x = 
, then
y = 
= 
=
It is in the ten's place. hope that helped
