Answer:

  (4x -3)(√3x -1)(√3x +1)

Step-by-step explanation:

Your factoring is correct for integers. However the quadratic term can be factored further using irrational coefficients. It is the difference of the squares of (√3)x and 1, so can be factored as such.

  12x³ -9x² -4x +3 = 3x²(4x -3) -(4x -3) = (3x² -1)(4x -3)

  = ((√3)x -1)((√3)x +1)(4x -3) . . . . . . further factoring the difference of squares

Let x be the number of boys, the number of girls will be 200-x

Number of boys with blue eyes x/3
Number of girls with blue eyes (200-x)/4
ll blue eyes ==> x/3 + (200-x)/4 = 57
Reduce to same denominator & solve for x
(4x + 600 - 3x)/12 = 681/12
x=81, the total number of boys & girls200-81 119

Identify the variation as direct, inverse, joint or combined. y = cx²
viva [34]

Answer:

combined variation          

Step-by-step explanation:

we have

y=cx^{2}

we know that

a)<u> in the interval </u>----> (0,∞)

If the value of x increase the value of y increase

so

Is a direct variation

b) <u>in the interval -</u>---> (-∞,0)

If the value of x increase the value of y decrease

so

Is a inverse variation

therefore

Is a combined variation

In psychology, there is a particular Mental Development Index (MDI) used in the study of infants. The scores on the MDI have app
ivann1987 [24]

Answer:

0.1587

Step-by-step explanation:

Here, mean=μ=100 and standard deviation=σ=16.

We have to find  P(average MDI scores of 64 children > 102)=P(xbar>102).

n=64

μxbar=μ=100

σxbar=σ/√n=16/√64=16/8=2

P(xbar>102)=P((xbar-μxbar)/σxbar>(102-100)/2)

P(xbar>102)=P(z>1)

P(xbar>102)=P(0<z<∞)-P(0<z<1)

P(xbar>102)=0.5-0.3413

P(xbar>102)=0.1587

Thus, the probability that the average is greater than 102 is 15.87%
