Bentley spun a spinner with 4 equal sections labeled 1–4. The spinner landed on 1 three times, on 2 four times, on 3 six times,

OverLord2011 [107]

Answer:

Step-by-step explanation:

Experimental probability : (Number of times event occur / total number of trials)

Total Number of trials = (3 + 4 + 6 + 3) = 16

Experimental probability :

For 1: P(1) :

3/16

For 2 : P(2) :

4/16 = 1/4

For 3: P(3)

6 /16 = 3/8

For 4 : P(4)

3 / 16

Theoretical probability :

The Theoretical probability of 1, 2, 3 and 4 are the same ;

Theoretical probability =

(Required outcome / Total possible outcomes)

For each of 1 - 4

Theoretical probability = 1 /4

Experimental probability of P(2) = 1/ 4 and is Hence, the same as the Theoretical probability

The equation for a parabola has the form y=????x2+????x+cy=ax2+bx+c, where ????a, ????b, and cc are constants and ????≠0a≠0. Fin

d1i1m1o1n [39]

The equation for this parabola satisfies

$\begin{cases}a-b+c=9\\9a+3b+c=-19\\16a-4b+c=-12\end{cases}$

(in other words, plug in each given point's coordinates $(x,y)$ into the equation $y=ax^2+bx+c$ )

Now,

$(a-b+c)-(9a+3b+c)=9-(-19)\implies-8a-4b=28\implies2a+b=-7$

$(a-b+c)-(16a-4b+c)=9-(-12)\implies-15a+3b=21\implies5a-b=-7$

and

$(2a+b)+(5a-b)=(-7)+(-7)\implies7a=-14\imples a=-2$

$2(-2)+b=-7\implies b=-3$

$(-2)-(-3)+c=9\implies c=8$

So the equation of the parabola is

$y=-2x^2-3x+8$

Factor the greatest common factor out of 8x^3 + 28x^2 + 40x

Liula [17]

Answer: $4x(2x^2+7x+10)$

Step-by-step explanation:

The Greatest Common Factor (GCF) of a polynomial is defined as the largest monomial that is a factor of all the terms of the polynomial.

In this case, given this polynomial:

$8x^3 + 28x^2 + 40x$

You can factor out the Greatest Common Factor applying this procedure:

1. Write the terms of the polynomial in prime factor form:

$8x^3=2*2*2*x*x*x\\\\28x^2=2*2*7*x*x\\\\40x=2*2*2*5*x$

2. Identify the factors the terms have in common (this will be the Greatest Common Factor). In this case this is:

$GCF=2*2*x=4x$

3. Finally, rewrite the expression in factor form:

$4x(2x^2+7x+10)$
