1.Were your two estimates the same? Did the mean length of all the straws in the bag change in between selecting the two samples

? Explain your reasoning.
2.The actual mean length of all of the straws in the bag is about 2.37 inches. How do your estimates compare to this mean length?

3.If you repeated the same process again but you selected a larger sample (such as 10 or 20 straws, instead of just 5), would your estimate be more accurate? Explain your reasoning.





Remember that sample 1 mean= 4


Sample 2 mean = 3.8

The sum of two integers is 51. The larger number is 3 more than 5 times the smaller number. Find the value of the larger number
Alona [7]

Answer:

Larger number = 43

Step-by-step explanation:

Smaller number = x

Larger number = 5x + 3

Sum of two integers = 51

x + 5x + 3 = 51    

       6x + 3 = 51

             6x = 51-3

             6x = 48

               x = 48/6

                x = 8

Larger number = 5x + 3

                         = 5*8 + 3

                          = 40 + 3

                         = 43

A company is printing both CD and vinyl versions of the same album. The machines that produce the CDs and vinyl albums can both
Sophie [7]

explanation:

A phonograph record (also known as a gramophone record, especially in British English), often simply record, is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac; starting in the 1940s polyvinyl chloride became common, hence the name vinyl. In the mid-2000s, gradually, records made of any material began to be called vinyl records, or simply vinyl.

The phonograph disc record was the primary medium used for music reproduction throughout the 20th century. It had co-existed with the phonograph cylinder from the late 1880s and had effectively superseded it by around 1912. Records retained the largest market share even when new formats such as the compact cassette were mass-marketed. By the 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the record left the mainstream in 1991.[1] Since the 1990s, records continue to be manufactured and sold on a smaller scale, and during the 1990s and early 2000s were especially used by disc jockeys (DJs) and released by artists in mostly dance music genres, and listened to by a growing niche market of audiophiles. The phonograph record has made a niche resurgence as a format for rock music in the early 21st century – 9.2 million records were sold in the US in 2014, a 260% increase since 2009.[2] Likewise, sales in the UK increased five-fold from 2009 to 2014.

2. angle ABE = angle MNP <br><br> Write another valid congruency statement:​
Free_Kalibri [48]

Given:

\Delta ABE\cong \Delta MNP

To find:

The congruent angles and sides, then find the another valid congruency statement.

Solution:

We have,

\Delta ABE\cong \Delta MNP

We know that, corresponding parts of congruent triangles are congruent (CPCTC).

Using CPCTC, we get

Angles:

\angle A\cong \angle M

\angle B\cong \angle N

\angle E\cong \angle P

Sides:

AB\cong MN

BE\cong NP

AE\cong MP

The another congruent statement is \Delta BEA\cong \Delta NPM.

Therefore, the required table is

Angles                                              Sides

\angle A\cong \angle M                                        AB\cong MN

\angle B\cong \angle N                                        BE\cong NP

\angle E\cong \angle P                                        AE\cong MP

The another congruent statement is \Delta BEA\cong \Delta NPM.

BartSMP [9]
5  \frac{3}{4} -1 \frac{7}{8} =  \frac{23}{4} - \frac{15}{8} = \frac{46}{8} - \frac{15}{8} = \frac{46-15}{8} = \frac{31}{8} = \boxed {3 \frac{7}{8} }
