32. $<u>23.06</u>
Step-by-step explanation:
30. 8.54+7.50+9.38 = 25.42
31. 6.99+5.99+8.50 = 21.48
32. 8.50+5.33+9.23 = 23.06
Your answer is: -14k-14
Step-by-step explanation:
5(-3.4k-7)+(3k+21)
_17k-35+3k+21
-14k-35+21
-14k-14
There are 8 possible outcomes so that means the probability will have a denominator of 8.
Now, there is only one of the eight outcomes that has zero tails.
Therefore the probability of getting zero tails after tossing a fair coin three times in succession is
9:14 and a:7 are equal ratios 14/2=7 and 9/2=4.5 so the answer is 4.5
