Answer:
(-4/3), 0.4, 0.8, √2, √11
Step-by-step explanation:
√11=3.316624790355399849114932736670686683927088545589353597058
0.4
(-4/3) = -1.33333333333333333333333333333333333333333333333333333333
0.8
√2=1.414213562373095048801688724209698078569671875376948073176
Thus :
(-4/3)
0.4
0.8
√2
√11

Answer:
They traveled exactly 25% of the distance
Step-by-step explanation:
Answer: 1. 7
2. 100
3. 193.8
4. 0.8
5. 90.6
Step-by-step explanation:
1. Given the data 9,3,10,12,4,5,12,2
For finding the median we arrange it in ascending order
2,3,4,5,9, 10,12,12
Since the no of observations are even
∴ median =![\frac{n/2 th term + (n/2 + 1)th term}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%2F2%20th%20term%20%2B%20%28n%2F2%20%2B%201%29th%20term%7D%7B2%7D)
= ![\frac{5+9}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%2B9%7D%7B2%7D)
=![\frac{14}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B14%7D%7B2%7D)
=7
i.e. Median =7
2. Given the data
23, 95,100,23,100,100
Since the no 100 is repeated thrice i.e. the maximum no of times
∴ Mode=100
3.
Given the data
108, 305,252,113, 191
Mean=![\frac{108+305+252+113+191}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B108%2B305%2B252%2B113%2B191%7D%7B5%7D)
=![\frac{969}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B969%7D%7B5%7D)
=193.8
4. Money spent in the first week
= $11.52, $6.48, $5.99, $14.00, and $9.50
Total for the first week
=11.52+6.48+5.99+14.00+9.50
=$47.49
Now she spent $4 more in the second week
i.e.$47.49+4
=51.49$
Increase in mean =![\frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D)
=0.8
5.
Given
2 students scored 100 each
9 students scored 95 each
10 students scored 90 each
3 students scored 80 each
1 student scored 70
Total score of students =![2\times100+ 9\times 95+10\times90+3\times80+70\times1](https://tex.z-dn.net/?f=2%5Ctimes100%2B%209%5Ctimes%2095%2B10%5Ctimes90%2B3%5Ctimes80%2B70%5Ctimes1)
=2265
The average score
=![\frac{2265}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B2265%7D%7B25%7D)
=90.6
A logarithm is defined as a power to which a number must be raused to in order to get another number. For example,
![log_{2}(8) = 3](https://tex.z-dn.net/?f=%20log_%7B2%7D%288%29%20%3D%203)
This is because
![{2}^{3} = 8](https://tex.z-dn.net/?f=%20%7B2%7D%5E%7B3%7D%20%3D%208)
So if we have
![log(13) = x](https://tex.z-dn.net/?f=%20log%2813%29%20%3D%20x)
We have to determine what number must 10 be raised to in order to give 13 so we have
