Answer:
Step-by-step explanation:
Given the expression
First, factor each denominator:
1.
2.
Now the expression is
Now, multiply the first numerator by (y-3) and the second by (y-4) and write the result as a fraction with denominator
This fraction cannot be simplified more.
The correct answer is answer choice C
Answer:Experimental probability is the result of an experiment. Theoretical probability is what is expected to happen.
Step-by-step explanation:
<span>0.053
The standard deviation of a binomial variable is
sqrt(n*P*(1-P))
where n is the sample size and P is the probability of one of the outcomes.
The sample size is 55 and we'll assume that both male and female are equally likely outcomes.
standard deviation = sqrt(55*.5*.5) = 3.7081%
44% is 1.6181 standard deviations away from the mean of 50%.
Looking this up on a standard deviation chart gives .0526 probability which we'll round to 0.053</span>
