Hello,

14bx²-7x^3-4b+2x= -7x^3+14bx²+2x-4b
=-7x²(x-2)+2(x-2b)
=(x-2b)(-7x²+2)
=(2b-x)(7x²-2)

Answer:

$(2b-x)(7x^2-2)$

Step-by-step explanation:

We have to factor the expression $14bx^2-7x^3-4b+2x$

We apply the method of grouping to factor it.

Make groups

$(14bx^2-7x^3)+(-4b+2x)$

Take GCF

$7x^2(2b-x)-2(2b+x)$

Finally, factored out the common factor

$(2b-x)(7x^2-2)$

The factored form of the given expression is

$(2b-x)(7x^2-2)$

Answer:

0.7755

Step-by-step explanation:

If 120 CDs are defective, the number of non-defective CDs in the batch is:

$n=1950-120\\n=1830$

In order for the batch to be accepted, all of the 4 CDs in the sample must not be defective, the probability of that happening is:

$P=\frac{1830}{1950}*\frac{1829}{1949} *\frac{1828}{1948} *\frac{1827}{1947}\\P=0.7755$

The probability that the entire batch will be accepted is 0.7755.

The population of Dawn land is changing exponentially. This change is modeled by the function f(x) = 60,000(1.01)x . Interpret t

LiRa [457]

Answer:

The function has an initial population size of 60,000 which increase at a rate of 1%

Step-by-step explanation:

Given the expression :

f(x) = 60,000(1.01)^x

Since 1.01 > 1 (exponential

The general form of an Exponential growth function.

y = p(1 + r)^x

p = 60000 = initial population

1 + r = 1.01 ; where r = growth rate

r = 1.01 - 1 ; r = 0.01 =

r = 0.01 * 100% = 1% growth rate

Suppose f varies directly as g, and f varies inversely as h. Find g when f = 10 and h = –12, if g = 56 when h = –2 and f = –7. R

kow [346]

Answer:

-480

Step-by-step explanation:

If f varies directly as g, and inversely as h, then we can write the variation equation:

$f=\frac{kg}{h}$ , where k is the constant of variation.

If g=56 when h=-2 and f=-7, then we substitute these values into the formula to find the value of k.

$-7=\frac{k(56)}{-2}$

$-7\times -2=56k$

$k=\frac{14}{56}=\frac{1}{4}$

The equation now becomes:

$f=\frac{g}{4h}$

if f=10 and h=-12, then;

$10=\frac{g}{-48}$

$g=-48\times 10=-480$

The correct answer is B.
