Write x2 − 6x + 7 = 0 in the form (x − a)2 = b, where a and b are integers.
Mariulka [41]
X² − 6x + 7 = 0

Let's complete the square [x²-6x+(??)²] -(??)² +7 = 0

As you noticed we have added the unknown square & also subtract the same so that not to change the equation

The question now is to calculate this square (??)²

We know that the middle term (6x) is twice the square root of the 1st times the square root of the 2nd, That is 6x=2x (multiply) √(??)²

6x = 2x?? & ??=6x/2x===> ?? =3 & (??)² =9

Hence plug (??)² into the equation above:

x² - 6x + 9 - 9 +7 =0

(x²-6x+9) -9 + 7 =0

(x-3)² -2 =0 ====> (x-3)² = 2 (that is B)

You have a jar of marbles with 7 red, 12 blue, 6 yellow, and 9 white. What is the probability of selecting a marble that is not
Schach [20]

Answer:

The probability of selecting a marble that is not red, replacing it and then one that  is white is 0.2102

Step-by-step explanation:

Number of red marbles = 7

Number of blue marbles = 12

Number of yellow marbles = 6

Number of white marbles = 9

Total marbles = 7+12+6+9=34

Probability of selecting red marble =\frac{7}{34}

Probability of selecting no red marble = 1-\frac{7}{34}=\frac{27}{34}

Now replacing it one marble is drawn again

So, Probability of getting white marble =\frac{9}{34}

So,the probability of selecting a marble that is not red, replacing it and then one that  is white =\frac{27}{34} \times \frac{9}{34}=0.2102

Hence the probability of selecting a marble that is not red, replacing it and then one that  is white is 0.2102
