14. 2x-1 = 0, x+7=0
x = 1/2, x = -7
15. x^2 + 3x - 10 = 0
(x + 5)(x - 2) = 0
x = -5, x = 2
16. x^2 - 25 = 0
(x-5)(x+5)
x = 5, x = -5
To get percent error you take actual-predicted and divide by the actual then multiply by 100 to get the percent.
65-50=15
15/60=0.25
0.25 times 100 =25%
65% of 39 is 60 the answer is 60
Answer:
no yes no i dumb
Step-by-step explanation:
Part 1:the answer is 1/36
each time we roll the dice, the whole probabilities are 6
if we roll it two times
6*6=36
part 2
it's 1/8
each time we flip a coin, the whole probabilities are 2
if we flip it 3 times
2*2*2=8
good luck
