To make a positive profit p(x)>0 we need to make:
Now we solve this for x:
We have:
a = -2
b = 7
c = -3
We will use formula for quadratic equation:
We got two solutions. One is fraction other is whole number. We will not consider fraction because the amount of muffins sold must be whole number. So our solution is:
x>3
let's see
u + xy
Plug in numbers that you know:
20 + 9 * 8
20 + 72
92
Answer:
38%
Step-by-step explanation:
Option: 38%.
Total number of numbers: 150
Number of odd numbers: 72
Number of nines: 15
Number of odd numbers other than nine: 72 - 15 = 57
Probability = [number of odd numbers other than nine] / [total number of numbers] = 57/150 = 0.38
0.38 = 38%

Answer:</h2>
The correct options are:
Choice A
Choice C
and Choice E
<h2>
Step-by-step explanation:</h2>
We are asked to find the value of:
60% of 94
We know that: it is represented as:
Choice A)
We know that:
could also be written as:
Since we multiplied and divide by 10 such that:
Hence, option: A is correct.
Choice B)
This option is incorrect.
Since by choice A we get that the correct expression is:
Choice C)
We get:
This option is correct.
Since,
Choice D)
This option is incorrect because the actual expression is:
Choice E)
[/tex]\dfrac{60}{100}\cdot 94[tex]
This is the correct expression.
