Answer:
The number of ways the grasshopper can reach the desired destination are 9 ways
Step-by-step explanation:
The directions in which the grasshopper can jump are;
One block north and one block west
By counting, we have;
The number of possible ways are through blocks
1) 1, 2, 5, 6, 8, 10
2) 1, 2, 5, 6, 8, 9
3) 1, 2, 5, 6, 7, 9
4) 1, 2, 3, 6, 8, 10
5) 1, 2, 3, 6, 8, 9
6) 1, 2, 3, 6, 7, 9
7) 1, 2, 3, 4, 7, 9
8) 15, 14, 16, 12, 11, 10
9) 12, 13, 16, 12, 11, 10
Therefore, there 9 ways the grasshopper can reach the desired destination.
Answer:
The 95% confidence interval for the true mean score is ![[73.539,76.461]](https://tex.z-dn.net/?f=%5B73.539%2C76.461%5D)
Step-by-step explanation:
Note that
where
is the sample mean,
is the upper critical value for the desired confidence level,
is the sample standard deviation, and
is the sample size.
Therefore, ![CI=75\pm 1.96\frac{5}{\sqrt{45}}\approx[73.539,76.461]](https://tex.z-dn.net/?f=CI%3D75%5Cpm%201.96%5Cfrac%7B5%7D%7B%5Csqrt%7B45%7D%7D%5Capprox%5B73.539%2C76.461%5D)

I hope this helps!
Answer:
1³ + 2³ + 3³ = 36
Step-by-step explanation:
Sum of 1³, 2³, 3³
Sum = addition (+)
1³
= 1 × 1 × 1
= 1
2³
= 2 × 2 × 2
= 8
3³
= 3 × 3 × 3
= 27
1³ + 2³ + 3³
= 1 + 8 + 27
= 36
1³ + 2³ + 3³ = 36
