Answer:
So option b is right.
Step-by-step explanation:
Given that a figure is located in Quadrant I.
The figure is transformed and the image is located in quadrant iv.
We have to select the option which would have resulted in this.
A) rotating 360 degrees would result in the same place i.e. I quadrant hence wrong.
B) rotating 180 degrees counterclockwise, will make y coordinate negative but x coordinate will remain as it is.
Hence we get image in the IV quadrant.
THis option is correct
C) Rotating90 degrees counterclockwise will not transform all the coordinates to the IV quadrant hence wrong
D) Rotating 270 degrees counterclockwise would make the image in III quadrant hence wrong
So option b is right.
Answer:
B. F:S = 17 to 19; S:F = 19 to 17
Step-by-step explanation:
Put the corresponding numbers in the corresponding parts of the ratio you want to write:
freshmen to sophomores (F:S)
17 to 19
___
sophomores to freshmen (S:F)
19 to 17
These pairs of numbers match choice B.
Multiply the amount she puts in the account every week by the number of weeks (w) and add that to what she already has saved:

Answer:
About 3 years Speedy Jet printers be guaranteed.
Step-by-step explanation:
Given : Quality control studies for Speedy Jet Computer Printers show the lifetime of the printer follows a normal distribution with
mean
and standard deviation 
If the company wishes to replace no more than 10% of the printers.
To find : How long should Speedy Jet printers be guaranteed ?
Solution :
Using Z- table,
Z value corresponding to 10% or 0.10 = -1.28.
Applying z-score formula,

The value of x is given by,

Substitute the values,



So, approx 3 years.
Therefore, About 3 years Speedy Jet printers be guaranteed.
