2/3 would be heads because it’s out of 3 coins
I = Prt
I = $3000*0.07*(6/12)
I = $105
$105.00 is earned on the investment.
#20 16/36 = 4/d 4 x 36 = 144/16= 9 d=9 #24 144/40 = x/5 144 x 5/40=18 x=18
Answer: It is proportional because 195/3 equals 65 and 325/5 equals 65 as well, so it is proportional.
Hope this helps! :)
If you find the discriminant it will tell you the number and types of roots. The discriminant is the value b^2 -4ac.
a = 1
b = 1
c = 1
1^2 - 4*1*1
1-4 = -3
Since this is a negative number there will be 2 complex roots.
