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>
Answer:
90
Step-by-step explanation:
Answer:
u ≈ 5.7
Step-by-step explanation:
Using the Sine rule in Δ TUV, that is
= , substitute values
= ( cross- multiply )
u × sin26° = 2.5 × sin85° ( divide both sides by sin26° )
u = ≈ 5.7 ( to 1 dec. place )
For this case we have the following system of equations:
We can Rewrite the system of equations of the form:
Where,
A: coefficient matrix
x: incognita vector
b: vector solution
We have then:
Then, the determinant of matrix A is given by:
Answer:
The determinants for solving this linear system are:
Answer:
f(g(25)) = -5
Step-by-step explanation:
You have to put 25 in place of x in g, and after, you take the result and put in place of x in f:
g(5) = √25 = 5
f(5) = 5^2 -6•5
f(5) = 25 -30
f(5) = -5
