a+b+c=9 and a2+b2+c2=35 then by using identity
(a+b+c)2=a2+b2+c2+2ab+2bc+2ca,we get the answer 9x9=35+2(ab+bc+ca)
2(ab+bc+ca)=9x9-35
2(ab+bc+ca) =81-35then we get ab+bc+ca=46/2 so ab+bc+ca=23
Over which interval(s) is the function decreasing?
Answer:
B) 0.45
Step-by-step explanation:
The total number of students is:
4 + 5 + 4 + 6 + 10 + 8 + 2 + 1 = 40
The number of students with brown hair is 10 + 8 = 18.
So the probability is:
P = 18/40 = 0.45
Circumfernce=diameter times pi
given that we should use 3.14 for pi
and diameter is 11.9
circumfernce=11.9 times 3.14=37.366
the circumference is 37.366cm
