The weight of solid clay brick is 66.465 ounces, if solid brick with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches and the clay weighs 1.055 ounces per cubic inch.

Step-by-step explanation:

The given is,

               A solid clay brick in the shape of a rectangular prism.

               A length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches.

               The clay weighs 1.055 ounces per cubic

Step:1

              Formula for volume of rectangular prism,

                                  Volume, V= whl...................(1)

            Where, w - Width of the rectangular prism

                          h - Height of rectangular prism

                           l - Length of rectangular prism

            From the given,

                         w = 3.5 inches

                          h = 2.25 inches

                           l =  8 inches

           Equation (1) becomes,

                                              = (3.5)(2.25)(8)

                                              = (7.875)(8)

                                              = 63

                            Volume, V = 63 cubic inches

Step:2

          Weight of brick = Volume of brick × Weight per cubic inch

                                     = (63) (1.055)

                                     = 66.465 ounces

          Weight of brick = 66.465 ounces

Result:

            The weight of solid clay brick is 66.465 ounces, if solid brick with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches and the clay weighs 1.055 ounces per cubic inch.

Over the past several years, the proportion of one-person households has been increasing. The Census Bureau would like to test t
bixtya [17]

Answer:

For this case we can find the critical value with the significance level \alpha=0.05 and if we find in the right tail of the z distribution we got:

z_{\alpha}= 1.64

The statistic is given by:

z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}} (1)  

Replacing we got:  

z=\frac{0.344 -0.27}{\sqrt{\frac{0.27(1-0.27)}{125}}}=1.86  

Since the calculated value is higher than the critical value we have enough evidence to reject the null hypothesis and we can conclude that the true proportion of households with one person is significantly higher than 0.27

Step-by-step explanation:

We have the following dataset given:

X= 43 represent the households consisted of one person

n= 125 represent the sample size

\hat p= \frac{43}{125}= 0.344 estimated proportion of  households consisted of one person

We want to test the following hypothesis:

Null hypothesis: p \leq 0.27

Alternative hypothesis: p>0.27

And for this case we can find the critical value with the significance level \alpha=0.05 and if we find in the right tail of the z distribution we got:

z_{\alpha}= 1.64

The statistic is given by:

z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}} (1)  

Replacing we got:  

z=\frac{0.344 -0.27}{\sqrt{\frac{0.27(1-0.27)}{125}}}=1.86  

Since the calculated value is higher than the critical value we have enough evidence to reject the null hypothesis and we can conclude that the true proportion of households with one person is significantly higher than 0.27

Answer:

20) 8 years

21) Tori could paint the room alone for 3 hours, Sydney could paint the room alone for 5 hours.

Step-by-step explanation:

A = P ( 1 + r/n ) ^ nt.

8000 = 5000 ( 1 + 6%/4) ^ 4t

8000 = 5000 ( 1 + 0.06/4) ^4t

8000 = 5000 ( 1 + 0.015 ) ^ 4t

8000 = 5000 ( 1.015 ) ^ 4t

8000 / 5000 = ( 4.06 / 4 ) ^ 4t

8/5 = ( 203/200 ) ^ 4t

b = aᶜ ⇔ logₐb = c

Answer:

C and D

Step-by-step explanation:

A box plot display consist of a five-number summary. The five-number summary includes the following five values that is depicted in the box plot display:

1. Min value: the least value or smallest value indicated at the end of the whiskers to our left.

2. Max value: the largest value in the data set indicated at the end of the whisker to our right.

3. The median: this is a measure of center indicated by the vertical line that divides the rectangular box into 2.

4. The Upper quartile (Q3): this is indicated by at the end of the rectangular box at our far right.

5. The lower quartile (Q1): this is indicated at the beginning of the rectangular box from our left.

The interquartile range is the difference between the Q3 and the Q1, which can be used as a measure of spread of a data set.

Therefore, the most appropriate measures of center and spread for the data set above, are the median and the interquartile range respectively.

The correct choices are option C and D.
