Answer:
Step-by-step explanation
2. you gave that there is a 40% chance that her instructor will be watching, which means that there is a 60% chance he will not be watching (100% - 40%).
3. you gave that there is a 90% chance of making a bull's eye, and 40% chance the instructor will be watching
since those two events are independent of each other, the chance of both of them happening is the product of the two chances, namely 0.9 x 0.4 = 0.36, or 36%

Answer:
Step-by-step explanation:
Answer:
2w^2 - 6w
Step-by-step explanation:
Length is equivalent to 2w - 6
width is equivalent to w
area involves w x (2w - 6)
expanded form: w(2w - 6) --) 2w^2 - 6w
First, convert both fractions into improper fractions:
-2 and 1/4= -9/4
-4 and 1/2= -9/2
Now we can find the product!
-9/4 x -9/2= 81/8
(Remember that when you multiply two negatives, the product turns positive)
And because 81/8 cannot be reduced, to find your final answer, just covert 81/8 into a mixed fraction!
81/8= 10 and 1/8
Hope this helps!
