Answer:
the slope of the given line is -8
Step-by-step explanation:
(6,9) and (7,1)
To find the slope of the given line we use formula
the value of x1 is 6 and y1 is 9
the value x2 is 7 and y2 is 1
plug in the value in the slope formula
x = 4
Explanation:
Given the expression;
Add 4 to both sides
Square both sides
Hence the value of x is 4
standard error of the mean = 1.6960
Given -
Mean = 53 minutes
Standard deviation ( s ) = 53.9 minutes
n = 1010
standard error of the mean =
=
= 1.6960
For every £2 Jan gets, Cole gets £3.
10 ÷ 2 (Jan) × 3 (Cole) = 15
