Answer:
Women has better study habit than men.
Step-by-step explanation:
For knowing who has better study habits and attitudes toward learning we have to find the mean of both the women and men data.
The first step is that we only take first 18 values of both women(X) and men(Y) data, to make them of same length
Mean is used to measure the central tendency of data which represents the whole data in the best way. It can be found as the ratio of the sum of all the observations to the total number of observations.
Calculating all values:
= 141.0556
= 121.25
Thus, women has better study habit than men. Since Mean of X is larger than Mean of Y.
Answer:
1. 2x + 5y = 5
2. 3x + 2y = -9
Step-by-step explanation:
35km; Since the points on the map are one millionth of their actual size, simply multiply by one million and convert from there.
35*1,000,000 = 35,000,000mm
35,000,000/1000 = 35,000m
35,000/1000 = 35km
