A cat breeder suspects her kittens weigh more than the larger population of kittens. A random sample of 25 of her kittens were w

eighed. The sample weighed an average of 1.15 pounds. The population weight of kittens follows a normal distribution with a standard deviation of 0.4 pounds. Using a significance level of 0.05, test the claim that the mean weight of kittens is more than the larger population of 1.0 pounds. What is the test statistic? Give 3 decimal places.

Use the grouping method to factor 4x3 + 20x3 - 3x - 15
ivann1987 [24]

12+20•3-3x-15

multiply the numbers : 20•3 = 60

12+60-3x-15

group like terms

-3x+12+60-15

add and subtract the numbers : 12+60-15=57

final answer = -3x+57

Fiesta28 [93]

Answer:

The values are evaluated below.

Step-by-step explanation:

Given function is

-x^4-7x^3-12x^2

We have to find the domain, range, rel max, rel min, end behaviour, increasing or decreasing intervals and zeros of polynomial.

Domain:

The domain of a function is the set of all possible values of x for the given function.

Here domain is set of all real numbers R.

Range:

The range is the resulting y-values we get after substituting all the possible x-values.From the graph we see that

The range is -\infty

Relative maxima and minima of a function,  are the largest and smallest value of the function on an entire domain of function.

Relative max of -x^4-7x^3-12x^2 is 0 at x=0

and \frac{3}{512}(133\sqrt57-471) at x=\frac{-21}{8}-\frac{\sqrt57}{8}

Relative min is

\frac{-3}{512}(471+133\sqrt57) at x=\frac{-21}{8}+\frac{\sqrt57}{8}

From the graph we see that

End behaviour is  As \\x->\infty, f(x)->-\infty\\x->-\infty, f(x)->-\infty\\

Increasing intervals and decreasing intervals are

Increasing: \frac{1}{8}(\sqrt57-21)

Decreasing: \frac{1}{8}(-21-\sqrt57)  

Zeroes are :

-x^4-7x^3-12x^2=0

⇒ (-x^2)(x^2+7x+12)=0

⇒(-x^2)(x+3)(x+4)=0

Hence, zeroes are 0, 0, -3, -4
