56% of U.S. Adults have very little confidence in newspapers. You randomly select 10 U.S. Adults. Find the probability that the number of U.S. Adults who have very little confidence in newspapers is (a) exactly five, (b) at least six, and (c) less than four.

The profit the landscaper receives in a week that he services 36 lawns = $3600.

Step-by-step explanation:

i) let the profit made by the landscaper be known as y

ii) let the number of lawns serviced be = x

iii) let k be a constant to represent an average price of a lawn that is serviced

iv) therefore we can write a linear equation for the profit made by the landscaper as   y = kx

v) therefore  we know from given information that  2000 = 25k and also that   600 = 11k .

vi) Subtracting the second equation in vi) from first equation in vi) we get

 1400 = 14k.

vii) therefore k = 100.

viii) therefore for 36 lawns the profit is y = 100 36 = $3600.
