Answer:
Yes
Step-by-step explanation:
Since P(A)=0.7 and P(A and B)=0.28, then P(B) must be 0.4 because 0.7*0.4=0.28.
Since P(A and B) is a combined probability, P(A) and P(B) are independent.
Number 7 is the x axis 11 is (4,2)
First note the domain of the expressions on either side of the equation,
√<em>x</em> is defined only for <em>x</em> ≥ 0, so we need to have
and
but <em>x</em> ² ≥ 0 for all real <em>x</em>, so both conditions will always be satisfied.
Back to the equation - take the square of both sides and solve for <em>x</em> :
A non-terminating and no -repeating decimal
