<u>To tell which cubic unit of measure that should be used</u>:

   ⇒ we should examine the unit of the side lengths

<u>First question (a):</u>

  • a rectangular prism that is 4cm by 9 cm by 2cm

            ⇒ must use <em>cm³ </em>as cubic unit of measure

               ⇒ as all sides are centimeters

                  ⇒<u>Answer: cubic centimeters or cm³</u>

<u></u>

<u>Second question(b):</u>

  • a rectangular prism that is 5m by 4m by 9m

            ⇒ must use <em>m³</em> as cubic unit of measure

               ⇒ as all sides are meters

                  ⇒<u>Answer: cubic meters or m³</u>

<u></u>

<u>Third question(c)</u>:

  • a rectangular prism that gives only two side length: 10dm, 6dm

              ⇒must use <em>dm³</em> as cubic unit of measure

                 ⇒ as all of the sides given are in decimeter

                     ⇒<u>Answer: cubic decimeter or dm³</u>

<u></u>

<u>Fourth question(d):</u>

  • a cube that gives only one side length: 56mm

              ⇒ must use <em>mm³</em> as cubic unit of measure

                  ⇒ as all the given sides with side lengths are in millimeters

                      ⇒ <u>Answer: cubic millimeters or mm³</u>

<u></u>

<u>Fifth question(e):</u>

  • a rectangular prism with two side length: 1m, 10m

              ⇒ must use <em>m³</em> as cubic unit of measure

                  ⇒ as all given sides with side lengths are in meter

                      ⇒<u>Answer: cubic meter or m³</u>

<u></u>

<u></u>

<em>In general</em>:

⇒ <em>when faced with these problems</em>

<em>    ⇒ look to the unit of measure of the majority of the side lengths</em>

<em>    ⇒ look to the unit of measure that the problem wants for the answer</em>

<u></u>

Answer:

Step-by-step explanation:

a. 4cm * 9cm * 2cm = 72 cm^3

b. 5m * 4m * 9m = 180 m^3

c. 10dm * 36 dm^2 (because the square could also be represented as 6cm * 6cm) =360 dm^3

d. (56mm)^3 =  175616 mm^3

e. 10 m * 1 m^2 (because of the square) = 10m^3

As part of the Pew Internet and American Life Project, researchers conducted two surveys in late 2009. The first survey asked a
REY [17]

Answer:

The 95% confidence interval for the difference between the proportion of all U.S. teens and adults who use social networking sites is (0.223, 0.297). This means that we are 95% sure that the true difference of the proportion is in this interval, between 0.223 and 0.297.

Step-by-step explanation:

Before building the confidence interval we need to understand the central limit theorem and the subtraction of normal variables.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

Subtraction between normal variables:

When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.

Sample of 800 teens. 73% said that they use social networking sites.

This means that:

p_T = 0.73, s_T = \sqrt{\frac{0.73*0.27}{800}} = 0.0157

Sample of 2253 adults. 47% said that they use social networking sites.

This means that:

p_A = 0.47,s_A = \sqrt{\frac{0.47*0.53}{2253}} = 0.0105

Distribution of the difference:

p = p_T - p_A = 0.73 - 0.47 = 0.26

s = \sqrt{s_T^2+s_A^2} = \sqrt{0.0157^2+0.0105^2} = 0.019

Confidence interval:

Is given by:

p \pm zs

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

95% confidence level

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.

Lower bound:

p - 1.96s = 0.26 - 1.96*0.019 = 0.223

Upper bound:

p + 1.96s = 0.26 + 1.96*0.019 = 0.297

The 95% confidence interval for the difference between the proportion of all U.S. teens and adults who use social networking sites is (0.223, 0.297). This means that we are 95% sure that the true difference of the proportion is in this interval, between 0.223 and 0.297.

What is the solution for the following equation 3(2x+3)=2(3x+4)?
ki77a [65]

Answer:

<h2><u><em>no solution, the equation is false</em></u></h2>

Step-by-step explanation:

what is the solution for the following equation 3(2x+3)=2(3x+4)?

3 * (2x + 3) = 2 * (3x + 4)

6x + 9 = 6x + 8

6x - 6x = -9  + 8

0 = ±1

the equation is false
