What are the values of the coefficients and constant term of 0 = 4 – 7x2 + x in standard form?
katen-ka-za [31]

ANSWER

a =  - 7

b = 1

c = 4

EXPLANATION

The given quadratic equation is:

0 = 4 - 7 {x}^{2}  + x

We rewrite in the standard quadratic equation form to obtain,

- 7 {x}^{2}  + x + 4 = 0

Comparing this to the general standard quadratic equation.

a {x}^{2}  + bx + c = 0

We have my

a =  - 7

b = 1

c = 4

You are dealt one card from a 52-card deck. Find the probability that you are not dealt a non-picture card.
andreyandreev [35.5K]

Picture cards are Jacks, queens and Kings. There are 4 of each for a total of 12 picture cards.

52-12 = 40 non picture cards.

Probability of being dealt a non picture card would be 40/52

The probability of not being dealt a non picture card would be 1 - 40/52 = 12/52 = 3/13

Answer: 3/13
