Answer:

(C)85.56 cm², 12.4 cm

Step-by-step explanation:

The Area of the screen of the new phone is :

19.68cm² + Area of the current phone screen size

The current phone screen size has dimensions: 6.1 cm and 10.8 cm,

Area of the current phone screen size = 6.1 cm × 10.8cm

Area of the current phone screen size = 65.88 cm²

Hence, The Area of the screen of the new phone is :

19.68cm² + Area of the current phone screen size

= 19.68cm² + 65.88cm²

= 85.56 cm²

The new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and ___

The is calculated as:

85.56cm²/6.9cm

= 12.4cm

Therefore, the new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and 12.4cm

Option C is correct

If you have learned how to find the line of best fit manually, then you can do it that way. Perhaps you may want to just find a line that can connect at least two of the points and I believe that that line will be able to represent the other points because, in general, the points are pretty close to one another. 

If you don't want to do it manually and have a graphing calculator (which I recommend) then you can use that to find the line of best fit (and if you want then you can see how precise your points are with your r^2 value). Or there is a website (http://illuminations.nctm.org/Activity.aspx?id=4186), which you can use to help you to find the equation of that particular line. 

Once you have that done, then you can substitute 2009 for the x value in the equation and then see what y value the equation produces. That will then be your answer :)

LekaFEV [45]

Answer:

c. Cluster sampling

Step-by-step explanation:

Taking into account that the exercise researcher is looking with limited resources to study a population that is divided, her best option is cluster sampling, which is a method applicable to this type of population, we could select in each group randomly her sample, the observational study is discarded because she does not have much availability of time or resources, nor would the stratified study be useful because she should select subgroups and create them to take samples and this would take more time and resources and sampling systematic is not adequate because it must have all the individuals and after having the list select the sample, but as we know, it is a process that will study the number of individuals so this option is not feasible.

enot [183]
Remember
you can do anyting to an equaiton as long as you do it to both sidess

distributive property
a(b+c)=ab+ac
commutativ property
a+b=b+a

distribute
3(4x-2)=12x-6

12x-6=9+2x+5
add 6 both sides
12x+6-6=9+6+5+2x
12x+0=20+2x
minus 2x
10x=20
divide 10
x=2
