Answer:
57/64
Step-by-step explanation:
exactly 6 boys: (1/2)^6 BBBBBB
exactly 5 boys: 6*(1/2)^6 BBBBBG BBBBGB (and the 4 other slots the girl can fall)
at least 2 girls is equal to all other scenarios (where there are not 5 or 6 boys)
= 1 - [exactly 6 boys] - [exactly 5 boys]
= 1 - (1/2)^6 - 6*(1/2)^6
= 1 - 7*(1/2)^6
= 1 - 7(1/64)
= 1 - 7/64
= 57/64
Answer:
36
I want brainliest
Step-by-step explanation:
<em><u>6 x 3/1 or 6 x 3 </u></em>= 18
put the reds back in
<u><em>18 x 2 </em></u><em>=</em> 36
take the ones from his sister
Prime factorization for both numbers:
84 = 2*2*3*7
56= 2*2*2*7
prime factors: 2*2*7
answer: 28
A^2 + b^2 = c^2.....a and b are the legs and c is the hypotenuse
41^2 + 40^2 = c^2
1681 + 1600 = c^2
3281 = c^2...take sqrt of both sides, eliminating the ^2
sqrt 3281 = c
57.28 ...rounds to 57 = c
so the 3 sides of ur triangle are 57,41,and 40. The perimeter is all three sides added together. So the perimeter is : 57 + 40 + 41 = 138 ft <==
Answer:
c = 10
Step-by-step explanation:
3 is to 6 as 5 is to c:
3 5
----- = -----
6 c
Then 3c = 30, and c = 10
