Consider the following 8 numbers, where one labelled x is unknown. 24, 4, 1, x, 39, 5, 37, 48
Given that the range of the numbers is 66,
work out 2 values of x.

the probability that a bird is green (.30) is true

step-by-step explanation:

8

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
