Part A:

Since five states have four-star hotels, only those five states can claim at least one four-star hotel and since there are 50 states, we can write this as 5/50 or 1/10.

Part B:

50 - 5 = 45 states don't have a four-star hotel.

Part C:

45/50 or 9/10 of the states do not have a four-star hotel.

Best of Luck!

Answer: x(t) = 5cm*cos(t*pi/2s)

Step-by-step explanation:

This is a sinusoidal equation, so we can write this as:

x(t) = A*cos(c*t + p)  + B

where B is the axis around the movement, as the resting position is x = 0, we have B = 0

so x(t) = A*cos(c*t + p)

A is the amplitude of the oscilation, c is the frequency and p is a phase.

We know that when t = 0s, we have x(2s) = 5cm

if this is the maximum displacement, then knowing that the maximum of the cosine is cos(0) = 1

then we must have that p = 0

x(0s) = A*cos(0) = 5cm

then we have A = 5cm

Now, when t = 2s, we have:

x(2s) = 5cm*cos(2s*c) = -5cm

then 2s*c is the minimum of the cos(x) function, this is:

cos(pi) = -1

then 2s*c = pi

c = pi/2s.

then our function is:

x(t) = 5cm*cos(t*pi/2s)

The tables below show running hours of three printers that produce greeting cards and the total number of greeting cards produce
Annette [7]

Answer:

B. $0.50

Step-by-step explanation:

Assuming Printer C runs 60 hours (not 6) in Week 3, the equations for the number of cards per hour produced by each of the printers are ...

  • 40a +50b +45c = 7950
  • 45a +50b +40c = 7800
  • 55a +30b +60c = 9600

The solutions to these equations can be found by various means. A graphing calculator (or any of several web sites) can solve the matrix equation to tell you the card production rates (in cards per hour) of each of the printers are ...

  • a = 60
  • b = 30
  • c = 90

So the question about ink cost can be answered for printer B:

... ($15/hour)/(30 cards/hour) = (15/30) $/card = $0.50/card
