Answer:
R = 0.8815 ;
y = 6.14679X + 2.33028 ;
14.624
Step-by-step explanation:
Using an online correlation Coefficient calculator, the correlation Coefficient, R between the number of lawn fertilizer sold and the number of lawn mowers sold is 0.8815. This R value depicts a strong positive correlation between both variables.
The regression line equation obtained by Plotting the values to generate a linear model is :
y = 6.147X + 2.330
With ;
Slope or gradient being 6.147
Intercept = 2.330
C.)
x = 2
y = 6.147X + 2.330
y = 6.147(2) + 2.330
y = 14.624
a) The speed of car was 60 mph.
b) The speed of car was 45 mph.
Step-by-step explanation:
Given,
a = actual skid marks
p = test skid marks
Formula;
a) a = 144 feet, p = 36 feet
Putting in formula;
The speed of car was 60 mph.
b) a = 153 feet, p = 68 feet
Putting in formula;
The speed of car was 45 mph.
