1. false
2. true
3. true
4. true
5. true
6. false
Step-by-step explanation:
sub to tapl :L
F(x) = 5x - 4.....slope is 5
g(x) : (0,1)(2,5)
slope = (5 - 1) / (2 - 0) = 4/2 = 2 .....slope is 2
h(x) : (1,14)(4,15)
slope = (15 - 14) / (4 - 1) = 1/3..slope = 1/3
so the smallest slope would be : h(x) with a slope of 1/3
Answer:
2.42
Step-by-step explanation:
standard deviation= sqrt(variance)
Variance=E[X2] - E[X]2
E[X] = sum(X)/n=35/9, so E[X]2 = 1225/81
E[X2] =sum(X2)/n = 189/9 = 170/81
Variance= 476/81
Standard deviation = sqrt(476/81) ~2.42
The mixed number of it would be 5 42/45 if you're looking for the mixed number (to find the mixed number divide 267 and 45)
For the first 6 trips she walked 3.2 kilometers and for the next 6 she made another 3.2 which would be 6.4 kilometers for 12 trips now she made 3 more trips which is half of the amount she originally did so it would be half of the distance also so 3.2 divided by 2 is 1.6 kilometers so for the last 3 trips she walked 1.6 kilometers. now add up all the distance she walked so 6.4 kilometers for the 12 trips plus the 1.6 for the other 3 trips is 8 kilometers in total. she walked 8 kilometers after 15 trips.
