Answer:
Not that I'm a chemistry expert but mathematically,The total weight of the bar is directly proportional to the known weight of the bar and the given percentage. I worked it out and found that the the total weight of the bar is 30 ounces. This is how I did it
Step-by-step explanation:
80:24
100:n
80(n)=100×24
A little equation and after it's solve the variable (n) will be equal to 30
The unit is added after calculations so that's how the answer is <em><u>3</u></em><em><u>0</u></em><em><u> </u></em><em><u>oun</u></em><em><u>ces</u></em>
30: r = -32
38: n < -24
54: ?
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>
Units. cause square units are for area and cubic units are for volume.
