6 students have black hair, 3 students have blonde hair, and 21 students have brown hair. since percentages come out of 100% you can use ten as a smaller size, so 20% of 10 is 1, multiply that by three because our full percentage is out of 30, and you get 3, and so on.
Answer:
560x^3y^4.
Step-by-step explanation:
The (r+1)th term of (a + b)^r = nCr a^(n-r) b^r
We want the fifth term so r = 5 - 1 = 4:
(4 + 1)th term = 7C4 x^(7-4) (-2y)^4
= 35x^3 16y^4
= 560x^3y^4.
Answer:
If you mean the percentage error then look at this
Step-by-step explanation:
% error = <u>Estimated </u><u>-</u><u> </u><u>Actual </u> x <u>100 </u>
Estimated. 1
% error = <u>7000 - 5600</u> x <u>100 </u>
7000. 1
% error = <u>1400 x </u><u>100</u>
7000
% error = 140000/7000
% error = 20%
