100
Step-by-step explanation:
Answer:
Add all the numbers together in each box the take those two numbers and multply them.
Step-by-step explanation:
10+9+9= 28
18+4+10= 32
32x28= 896
I hope that helps.
Formula applied: p+/- Z*sqrt (p(1-p)/N)
Where
p=probability of those who will vote for candidate a = 120/400 = 0.3
Z = Critical value at 95% confidence interval = 1.96
N = Size of the sample = 400
Substituting;
Interval = 0.3+/- 1.96* sqrt (0.3(1-0.3)/400) = 0.3+/-0.045
Interval of population who will vote for candidate a at 95% confidence interval
= 0.3+0.045 to 0.3-0.045
=0.345 to 0.255 of the total population
-1.6 , -6/5 , -0.875, 0.9, 2.5
The negative number many seem high but since the greatest negative number is closer to zero it is higher than the other negative numbers.
The formula for slope is: m = (y2 - y1) / (x2 - x1) ---> m = (b - b) / (-a - a) = 0/(-2a) = 0
