Answer:
$978
Step-by-step explanation:
Given:
- y = amount of profit
- x = selling price of each widget
To find the maximum amount of profit, differentiate the equation, set it to zero and solve for x. Substitute found value of x into the original equation.
<u>Differentiate equation</u>
<u>Set differentiated equation to zero and solve for x</u>:
<u>Maximum profit</u>
Substitute x = 39 into the equation:
Therefore, max profit is $978
Answer:
The probability of randomly selecting someone who does not believe that some people see the future in their dreams =0.497.
Step-by-step explanation:
Given
Percent of Americans who Say they believe that some people see the future in their dreams=50.3%
Total percentages=100%
Therefore, Number of americans who say they believe that some people see the future in their dreams=50.3
The probability of randomly selecting someone who say they believe that some people see the future in their dreams =
Hence, the probability of randomly selecting someone who believe that some people see the future in their dreams, P(E)=0.503
Now, the probability of randomly selecting someone who does not believe that some people see the future in their dreams ,P(E')= 1-P(E)
The probability of randomly selecting someone who does not believe that some people see the future in their dreams =1-0.503
Hence,the probability of randomly selecting someone who does not believe that some people see the future in their dreams=0.497.
Answer:
n = 1/2
Step-by-step explanation:
So the equation is 4/5n - 1/5 = 2/5n.
So, the first thing that we need to do is get the variable on one side.
So, to do that we need to subtract 4/5n on both sides.
Now our equation is -1/5 = -2/5n
Now the last step is to simplify.
To do that, we need to multiply by the reciprocal of 2/5 on both sides.
That leaves us with 1/2 = n
Answer:
Step-by-step explanation:
Given the table of domain and range
<u>Using the points, lets find the slope-intercept form</u>
<u>The slope</u>
- m = (5-1)/(2-1) = 4/1 = 4
<u>y-intercept</u>
- 5 = 4*2 + b
- b = 5 -8
- b = -3
<u>So the function is</u>
- y = 4x - 3
- or
- f(x) = 4x - 3
