Answer:
The answer is (4x - 3)/(x + 6)
Step-by-step explanation:
∵ (4x² - 7x + 3)/(x² + 5x - 6)
Factorize the numerator:
4x² - 7x + 3 = (4x - 3)(x - 1)
Factorize the denominator:
x² + 5x - 6 = (x - 1)(x + 6)
∴ (4x - 3)(x - 1)/(x - 1)(x + 6) ⇒ reduce (x - 1) from in up and down
∴ The answer is (4x - 3)/(x + 6) ⇒ the fourth answer
Determine the number of standard deviations that needs to be subtracted from or added to the mean in order to arrive to the values given.
(1) 45 = 61.2 - 21.4n ; n = 0.757
(2) 78 = 61.2 + 21.4n ; n = 0.785
(3) 62 = 61.2 + 21.4n ; n = 0.037
(4) 90 = 61.2 + 21.4n ; n = 1.346
(5) 31 = 61.2 - 21.4n ; n = 1.4
Therefore, the answer for 45 and 78 is approximately 1 (letter b), for 62 is zero (letter a), and for the last two numbers, more than 1 or two (letter c).
Your answer is: 123,456,789.
Hey!
Alright, the first step to solving this division problem would be to convert the mixed fraction into a simple fraction. To do that, we'll multiply the denominator by the whole number and then add that total to the numerator.
<em>Original Fraction :</em>
<em>New Fraction {Changed by Conversion} :</em>
Now that we've successfully done that we'll have to change the equation.
<em>Old Equation :</em>
÷
= ?
<em>New Equation {Changed by Flipping the Second Fraction and the Symbol} :</em>
·
= ?
Now we multiply straight across.
<em>Old Equation :</em>
·
= ?
<em>Solved :</em>
Almost done!
Now we have to simplify the fraction.
<em>Old Fraction :</em>
<em>New Fraction {Changed by Simplification} :</em>
Now just convert it to a whole number by removing the fraction line and the number, and that's it!

÷
equals</em></span>
15.
Hope this helps!
