Use the remainder theorem to find P(2) for P(x) = x^4 - 3x^3 - 6x^2 + 9 .

kramer

Step-by-step explanation:

soln;

given; p(x) = x^4 - 3x^3 - 6x^2 + 9

using remainder theorem;

p(x) = p(a)

= p(2)

= (2)^4 - 3(2)^3 - 6(2)^2 + 9

= -23

Find the circumference:

Circumference = pi x radius x 2 = 138.16 feet

Linear travel = circumference x rotations

linear travel = 138.16 x 20 = 2.763.2 feet.
Round off to 2,763 feet

You work for a marketing firm that has a large client in the automobile industry. You have been asked to estimate the proportion

quester [9]

Answer:

The sample size must be approximately 1067 to get a margin of error of 0.03.

Step-by-step explanation:

We are given the following in the question:

Margin of error = 0.03

Significance level = 5%

Margin of error =

$z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

Since, no prior proportions are given, we take

$\hat{p} = 0.5$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$0.03 = 1.96\sqrt{\dfrac{0.5(1-0.5)}{n}}\\\\\sqrt{n} = \dfrac{1.96\times 0.5}{0.03}\\\\\\sqrt{n} = 32.67\\n = 1067.3289\approx 1067$

Thus, the sample size must be approximately 1067 to get a margin of error of 0.03.

A kennel has eight adult dogs and 14 puppies what is the ratio of adult dogs two puppies use a multiplication to have comparison

frez [133]

Number of adult dogs a kennel has = 8 dogs.

Number of puppies = 14 puppies.

<h3>We need to find the ratio of adult dogs to puppies = Number of adult dogs: Number of puppies.</h3><h3>= 8:14.</h3>

Now, we need to write 8:14 in fraction form $\frac{8}{14} .$

Greatest common factor of 8 and 14 is 2.

$\frac{8}{14} = \frac{2\times 4}{2 \times 7}$ $=\frac{4}{7}$ .

<h3>Therefore, ratio of adult dogs to puppies is 4:7.</h3>
