Option C: 4(x^{2} -2x+1) is the factor

Explanation:

The given expression is 4x^{2} -8x+4

We need to determine the factor of the given expression.

The factor of the expression can be determined by taking 4 as a common factor because each term in the trinomial is a multiple of 4.

Hence, factoring the expression becomes,

4(x^{2} -2x+1)

Therefore, the factor of the given expression is 4(x^{2} -2x+1)

Hence, Option C is the correct answer.

The least square regression equation for the information provided is y = 9.72x - 40.776

<u>The general equation of a regression model can be expressed thus</u>:

  • y = bx + c

  • Slope, b = r(Sy/Sx)

Calculating slope, b :

  • b = 0.81(177.6 / 14.8) = 9.72

<u>Plugging the values of b, y and x into the equation in other to calculate c</u> :

696 = 9.72(75.8) + c

696 = 736.776 + c

c = 696 - 736.776

c = - 40.776

Therefore, the linear regression model can be expressed as : y = 9.72x - 40.776

Referring to the figure, find the value of x
olga2289 [7]

Answer:

x = 183

Step-by-step explanation:

(x -73)° + x° +67° = 360°

x-73+ x +67 = 360

x + x -73 +67 = 360

2x-6 = 360

2x = 360+6

x = 366÷2

x = 183

Check:

(183 - 73) = 110° , x = 183° , 67°

110° + 183° + 67° = 360°

The band has 30 more members than the school chorale. If each group had 10 more members, the ratio of their membership would be
vladimir1956 [14]

Answer:

80 members

Step-by-step explanation:

Let the band members be= b and the chorale members=  c

Then, according to question, b=c+30 and \frac{b+10}{c+10}=\frac{3}{2}

⇒2(b+10)=3(c+10)

⇒2b+20=3c+30

⇒2b-3c=30-20

⇒2b-3c=10

Now, substituting the value of b=c+30, we get

⇒2(c+30)-3c=10

⇒2c+60-3c=10

⇒-c=-50

⇒c=50

Therefore, b=c+30

b=50+30=80

Therefore, there are 80 members in the band.
