In a class of 29 students, 14 have a cat and 17 have a dog. There are 7 students who do not have a cat or a dog. What is the probability that a student chosen randomly from the class does not have a cat?

There is a 15 in 29 chance that the student will not have a cat.

Step-by-step explanation:

14 out of 29 students has a cat, 29-14=15

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

answer: c
