1. Dr. Anderson and R. A. Fisher in a paper entitled "The Use of Multiple Measurements in Taxonomic Problems".
(Annals of Eugenics, 1936) found the average petal length of the iris setosa to be 1.46 cm with a standard
deviation of 0.17 cm. Find the probability that a random sample of 20 petals will have an average length of at
least 1.50 cm

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
