Answer:
Step-by-step explanation:
The value of d is the average of the maximum and minimum values of the graph:
d = (3 +(-1))/2 = 1
The value of 'a' is the difference between the maximum value and the value of d:
a = 3 -d = 3 -1 = 2
The required values of 'a' and 'd' are 2 and 1, respectively.
Answer:
45) Option A
- This is because every option has different modes and 70 is the mode and only one option has the mode as 70.
Hence, option A is correct.
46) Option B
- In all the options, the mode and medians are same hence we only have to find the mean which will help us to reach our correct option. The mean will be 40/17 = 2.35
Hence, option B is correct.
13=10+3 so
13-7=3+10-7=3+3=6
Answer:
Simple random sampling
Step-by-step explanation:
Simple random sampling chooses at random members of the population. This allows all members an equal probability of being selected for the sample.
