(c) Find the number of sets where all three cards are the same for exactly $0$ attributes. (d) Find the number of sets where all
Cloud [144]

C. For the first card, there are three ways to choose the number of card.

For the another, there two options, and likewise there's only 1 choice of card. So there are 3 × 2 × 1 = 6 ways that the calculation can be chosen.

Doing this for the other attributes, we get 6 × 6 × 24 × 6 ways. But the order of cards does not count in a set of card, so we divide by 3! 6 * 6 * 24 × 6 ÷ 3! = 864. It means there are 864 sets for part.

D. The cards may have the same number, color, shapess, orshading.

However, also there are 6 × 24 × 6 × 3! = 144 sets of cards, If all the colors are thesame. How ever, also there are 144 sets of cards.

If all the calculation are the same. We get the same number for shape and shadings, so there are 4 × 144 = 576 sets of cards.

what is Probability?

Probability is branches of mathematics concerning numerical descriptions of how to the likely an event is to occurs, or how to the likely it is that a proposition is true. The probability of an event is a numbers between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the events and 1 indicates certain of cards.

The current I in a device is related to time t by the equation I=10t-5t^2+2.Calculate the maximum current and time taken to reac
taurus [48]

Answer:

  • maximum current: 7
  • time to reach maximum: 1

Step-by-step explanation:

The equation can be rewritten to vertex form to find the maximum value:

  I = -5(t^2 -2t) +2 . . . . . . factor leading coefficient from variable terms

  I = -5(t^2 -2t +1) +2 -(-5(1)) . . . . . add and subtract the square of half the t coefficient

  I = -5(t -1)^2 +7 . . . . . . write in vertex form

The vertex of the graph is at (t, I) = (1, 7).

The maximum current of 7 is reached at t=1.
