   2/7k=   -2

   -------    -------

     2/7       2/7

k=-7

To check do 2/7(-7) -3/8

                         -2 -3/8

and u get -2 3/8 but then u do 8*2= -16+3= 19

Ber [7]

Answer:

A1-60x+460

A2-50x+530

B-60x7+460

50x7+530

Step-by-step explanation:

A1 and A2-since x is equivalent to number of months we multiply the number of months then add it to the original cost to get how much total you get in the account.

B-you add 50 to 530 and 60 to 460 until they equal the same amount in this case its 7 times.

The complete factorization of -12x^3 + 14x^2 +6x is -2x(ax + 1)(2x-3). What is the value of a?
tester [92]

Answer:

a = 3

Step-by-step explanation:

-12x³+14x²+6x = -2x(ax+1)(2x-3)

<em>Divide both sides by -2x(2x-3)</em>

\frac{-2x(ax+1)(2x-3)}{-2x(2x-3)} = - \frac{12x^{3} }{-2x(2x-3)} + \frac{14x^{2} }{-2x(2x-3)} +\frac{6x}{-2x(2x-3)}

ax+1=3x+1

<em>Subtract 1 from both sides</em>

ax=3x

<em>Divide both sides by x</em>

a=3

Assume that when an adult is randomly​ selected, the probability that they do not require vision correction is 23​%. If 6 adults
KiRa [710]

Answer:

 P(X = 2) = 0.27894

Step-by-step explanation:

Given:

- The probability that no vision correction is required p = 0.23

- No. adults are randomly selected n = 6

Find:

- P ( Exactly 2 dont require vision correction)

Solution:

- We will declare a random variable X is the umber of adults out of 6 that do  not require vision correction. X follows a Binomial distribution:

                                    X~ B ( 6 , 0.23 )

- The probability required is P ( X = 2 )

- Using the pmf of binomial distribution we have:

                           P(X = 2) = 6C2 * (0.23)^2 * (0.77)^4

                           P(X = 2) = 15 * 0.0529 * 0.35153041

                           P(X = 2) = 0.27894
