Answer:
Binomial distribution,
n = 36 independent events,
p = 0.5 probability of success and of failure, as 1-p = p.
Mean of binomial distribution is np=18.
Variance is np(1-p)=9
Standard deviation is sqrt(variance)=3.
Answer:
Domain: [-4,4]
Range: [-4,6]
Step-by-step explanation:
To domain pertains to the x-coordinates, while the range pertains to the y-coordinates.
Looking at the graph, we can see that the farthest point to the left is (-4,3) and the farthest point to the right is (4,6). Now, we know that the domain is [-4,4].
Looking at the graph, we can see the highest point is (4,6) and the lowest point is (0,-4). Now, we know the range is [-4,6].
Now, we know that the domain is [-4,4] and the range is [-4,6].
Answer:
163
Step-by-step explanation:
Given the following :
Number of visitors on Friday = 3,260
Number increased by 15% on Saturday
Projected percentage increase on Saturday = 20%
Actual percentage increase in number of visitors = 15%
Number of visitors on Saturday :
(100 + 15)% × 3260
115% * 3260
(115/100) * 3260
= 3749 visitors
Projected percentage increase = 20%
Projected number:
((100 + 20)% * 3260
120% * 3260
(120/100) * 3260
= 3912
Difference : (3912 - 3749) = 163
