Answer:
since angle a and b are vertical angles
therefore we can say that,
i) <A=<B
or,20x+10=30x-10
or,10+10=30x-20x
or,20=10x
.°. x=10.
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
Answer:
The answer is C.
In order to make an exponent positive, you just switch it to the opposite part of the fraction. So, for example,
x^-3= 1/x^3
or
1/x^-5 = x^5/1
You just switch it to the opposite part of the fraction, and make the exponent positive.
