Answer:
y= 
x -3
Step-by-step explanation:
slope-intercept form is y=mx+b
m= slope
b= y-intercept
so plugin your numbers with the given data...
and you get y=2/5x-3
For the graph, you start at -3 on the <u>y-intercept</u> and then <em>move right 5</em> and<em> up 2</em>
Graph is the picture below :)
Yes, it does.
An r-value, or correlation coefficient, goes from -1 to positive 1. -1 indicates a perfect decreasing match and 1 indicates a perfect increasing match. 0 indicates no relationship between the variables.
x' = 24/5
The rule for variable to variable' is multiply by 6/5, shown as y to y'
Answer: No, the normal curve cannot be used.
Step-by-step explanation:
The theorem of the Normal approximation states that if X is B(n,p) then for large n X is N(np, np(1-p)).
The accuracy of this approximation is good
i. for n > [10/p(1-p)]
ii. p is close to 1/2
Hence given p= 4% = 0.04,
q = 1 - 0.04 = 0.96
Let N = [10/p(1-p)]
We find N = 10/p(1-p) = 10/(0.04× 0.96)
N ~= 260
Since n < 260 and p < 0.5
The approximation is not a good one
