Mariahs earnings rate can be described in dollars per hour or hours per dollar. Mariah earns $10 for each hour she works at a movie theater. State this rate in two different ways, and describe the difference

Dollars per hour is $10 and hours per dollar is 6 minutes 15 seconds.

Step-by-step explanation:

Dollars per hour represents how much she earns for each hour of work. Hours per dollar represents how much she works to earn $1.

It is stated that Mariah earns $10 for each hour of work at the movie theater.

This is the "dollars per hour" rate since the base is 1 hour.

This means that she earns 10/60 = $0.16 for every minute she works at the theater. If we divide 1 by this number we find 1/0.16 = 6.25.

This is the minutes she has to work to earn $1. So her hours per dollar rate is 6.25 minutes which is 6 minutes 15 seconds.

I hope this answer helps.

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2

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
