The probability of spinning an even number on a spinner is 0.4. What is the probability of not spinning an even number, expressed as a percent?

60%

Step-by-step explanation:

There are only even and odd numbers.  If a number is not even, it is odd.  If the probability of spinning an even number is 0.4, or 40%, then just subtract that by the whole spinner, which is equivalent to 100%:

100% - 40%

= 60%

This means that the odds of spinning an odd number is 60%

Hope this helps!  Tell me if I'm wrong please!

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
