You would multiply negative on by -10x+5y=30 to get 10x-5y=-30
-10x-8y=30
10x-5y=-30
-13y=0
-13y/-13=0/-13
y=0
then you would plug y into -10x+5y =30
to get 10x=30
10x/10=30/10
x=3
the point would be (3,0)
Answer: n = 2401
Step-by-step explanation:
Given;
Confidence level = 2% - 99%
n = ? ( which is the sample size is unknown ).
Solution:
Where;
n = [z/E]^2*pq
Since no known value for ( p ) estimate is given, the "least biased" estimate is p = 1/2
Substituting the given data into the formula.
n = [1.96/0.02]^2(1/2)(1/2)
n = 2401
The minimum number of truck drivers the statistician needs to sample for an accurate result is 2401
Hence the name. In other words, a number is rational if we can write it as a fraction where the numerator and denominator are both integers.
