Step-by-step explanation:
Number of points lost after loosing a spaceship ![=50](https://tex.z-dn.net/?f=%3D50%20%20)
Number of spaceship lost ![=4](https://tex.z-dn.net/?f=%3D4%20%20)
Total number of points lost ![=4\times50=200](https://tex.z-dn.net/?f=%3D4%5Ctimes50%3D200%20%20)
Number of points earned after completion of level 3 ![=550](https://tex.z-dn.net/?f=%3D550%20%20)
Scoreof Reggie changed by points ![= 550-200=350](https://tex.z-dn.net/?f=%3D%20550-200%3D350%20%20)
Score will change by 350 points after completion of level 3
Answer:
Step-by-step explanation:
Given is the graph bell shaped.
We have to find the variance of the data
We see that the graph looks like a normal distribution curve symmetrical about x=19
Hence mean =19
Since we know maximum area covered within 3 std deviations on either side of mean, we can calculate 6 sigma value from the graph
Extreme left x value = 14 and right = 24
Hence 6 times std dev =24-14 =10
So std deviation = 10/6 =5/3
Variance = 25/9
Since 3 is less than 5, you round down. so the answer is 490,000
