A) The first one equals to 5
Step by step:
Change all denominators to 28, what you do to the bottom you do to the top.
After adding simplify.
Answer:
"2 + 2(-3)(7) = negative
-2(27 ÷ 9)+4= negative
(14 ÷ -2)(-6)= positive
(4 - 10) - ( 8 ÷ ( -2))= negative
Step-by-step explanation:
2 + 2(-3)(7) = -40
-2(27 ÷ 9)+4= -2
(14 ÷ -2)(-6)= 42
(4 - 10) - ( 8 ÷ ( -2))= -2"
Answer:
B) 0.55
The probability of the complement of Event A ( P( A⁻ )) = 0.55
Step-by-step explanation:
<u>Explanation</u>:-
<em> Given Event A and Event B are mutually exclusive.</em>
<em> Given data P(A) = 0.45
</em>
<em> P(B) = 0.35</em>
<em> P(C) = 0.25</em>
<em>The probability of the complement of Event A</em>
<em> P( A⁻ ) = 1 - P( A)</em>
= 1 - 0.45
= 0.55
<u><em>Final answer</em></u>:-
<em>The probability of the complement of Event A = 0.55</em>
