To get the probability that at least 8 of the words on the test are words that students know we need to do the following calculations.
<span>=[C(16,8)*C(10,2) + C(16,9)*C(10,1) + C(16,10)*C(10,0)] / C(26,10)

=0.132
Answer:
-43
Step-by-step explanation:
Input 6 where a is so then do -7 x 6 which would be -42

Answer:
109.5
Step-by-step explanation:
4 sides equals 360 degrees. 360 minus 96 and 45 is 219. divide 219 by 2 and boom theres your answer.

Hey there!!
The area given : 25 square yards
We will find the length of the square.
Square area = side²
side² = 25
side = √25
side = 5 yards.
Now convert this into inches
1 yard --> 36 inches
5 yards --> 180 inches
Area = 180²
Area = 32400 inches²
Hope my answer helps!!
