vladimir2022 [97]

Answer:

Step-by-step explanation:

a). Mean of the given data set = \frac{32+28+18+40+22}{5}

                                                  = 28

b).   x                     x-\overline{x}               (x-\overline{x})^2

     32          32-28 = 4                    16

     28          28 - 28 = 0                  0

     18           18 - 28 = -10                100

     40          40 - 28 = 12                 144

     22          22 - 28 = -6                 36

                                                 \sum({x-\overline x})^2 =  296          

c). Standard deviation = \sqrt{\frac{\sum (x-\overline{x})^2}{n}}

                                     = \sqrt{\frac{296}{5} }

                                     = 7.69

d). Mean of the new set of weights = \frac{32+33+34+35+36}{5}

                                                          = 34

   Since mean of the data set is more close to each data, standard deviation will be less than the deviation given in part (c).

Ratio of nickels t quarters in a dollar
egoroff_w [7]
Since the nickels are first and there are (1.00 /.05= 20) 20 nickels in a dollar the first number is 20 then next is quarters and there is (1.00 / .25= 4) 4 quarters in a dollar so the second number is 4 so now u have to simplify if you were told to 
the number 20 can be divided by 4 and the answer is 5 the number 4 is next divide by 4 and is 1 so the whole answer is 5 to 1 or 5:1<span>

A ___ thermometer has a liquid that _____ and rises in a ____ tube when it's temperature goes up; the liquid ___ and it's level
mojhsa [17]

Answer:

The answer is "bulb, expands, and glass ".

Step-by-step explanation:

The bulb thermometer is the common glass temperature sensor for which you might be grown up. This thermometer is filled with a liquid, typically mercury. Bulb thermometers work on the simple premise that it volume of the liquid varies in proportion to its volume.

It is a glass tube that is pre full with a fluid such as a hydrogen or liquor and is sealed at both sides. The fluid in the glass tube rises as the mercury inside the thermometer's bulb increases. When the temperature gauge is warm, the liquid inside flows up in the tube.

Solve the system of equations below by graphing both equations with a
Marat540 [252]
Graph using slope and the y intercept

So y=x+5
You would plot the y intercept (0,5) and then go up 1 and to the right 1

The next graph plot y intercept (0,-1) and then go down 2 and to the right 1

And should look like the image

And your solution should be (-2,3) which is option c
