∠1 + 57° = 123°
∠1 = 66°
Answer:
a) 0.70
b) 0.30
c) 12/45 =4/15
d) 2/45
Step-by-step explanation:
a) Prob of drawing a marble red or white = No of red and white marbles/total marbles
= 7/10 = 0.70
b) Prob of drawing a marble neither red nor white = 1-7/10 = 0.30
c) Prob of drawing two marble one red and one white at the same time
= 
d) Prob of drawing two marble one blue and orange white at the same time
= 
D>0 that means it has two real solutions (unequal).
<span>It can have one solution only if D=0 and complex solutions only if D<0. </span>
