Hi!
<em>Step:</em>
<h3>We need to divide $74.50 by 10.</h3><h3>So we get $7.450 </h3><h3>but we remove the 0 :)</h3><h3 /><h3>Knowing that x is the number of boxed lunches and the company would have to pay $7.45.</h3><h3 /><h3>we can just do <em>7.45x = y</em> where y is the total cost for the lunches. </h3><h3 /><h3 />
<em>So the answer is:</em>
<h3>$7.45</h3><h3 />
:D

Step-by-step explanation:
Assuming the readable scores are:
100, 82, 95, __ , 90, 81, 75, 83, __
We know the mean (or average) is 85, so:
85 = (100 + 82 + 95 + x + 90 + 81 + 75 + 83 + y) / 9
765 = 606 + x + y
159 = x + y
We know the lowest score is 75, so x and y must be at least 76. Possible answers are:
76 and 83
77 and 82
78 and 81
79 and 80
80 and 79
81 and 78
82 and 77
83 and 76
Answer:
2/0.74
Step-by-step explanation:
To solve the polynomial, factorize it.
2x³-11x²+18x-8=0
After factorizing:
(x-2)(2x^2 - 7x +4) = 0
now, solve each bracket one by one:
x-2 = 0
x = 2
Then
2x^2 - 7x + 4 = 0
use quadratic formula t get 0.74
