Answer:
1. 8:5
2. 4:7:9
3. 4:3
4. 1:7
Step-by-step explanation:
1. they both are in 7 times table
2. both in 8 times table
3. 15 times table
4. 10 times table
Given:
The speed, s, is measured in miles per hour, and distance, y, is measured in yards.
The regression line is given by
...(i)
To find:
The slope and y-intercept of the regression line.
Solution:
The general form of linear regression line is
...(ii)
where x is variable. In the given equation the variable is denoted by s.
On comparing (i) and (ii), we get
It means slope is 52.45 and y-intercept is 4.17.
The slope, b = 52.45, indicates that the distance increases by 52.45 yards for every one mile per hour of speed.
The y-intercept, a = 4.17, is the distance estimated by this model if the speed is zero miles per hour.
Therefore, the correct option is A.
2/7 not sure but that's what i got
Graphing the inequalities
y ≥ 0 are the points above the x-axis including the points along the x-axis
y < x are the points below the line y = x
x + y < 6 are the points below the line x + y = 6
The solution to this is the region bounded by the lines connecting the points
(0, 0)
(0, 6)
(3, 3)
