Answer:
756 is a reasonable estimate because the proportion of the sample whose favorite pizza is pepperoni is about 27 %
Step-by-step explanation:
given data
random sample = 150 people
favorite pepperoni pizza = 40
total of residents = 2800
number of residents favorite pizza = 750
solution
we get here first Proportion favorite pizza that is
Proportion =
Proportion = 0.27 = 27%
and now we get 27% of total of residents that is = 27% × 2800
= 756
so we can say 756 is a reasonable estimate because here proportion of an sample whose favorite pizza are pepperoni pizza about 27 %

Step-by-step explanation:
Answer:
The coordinates of point R are (7,6), second option
Step-by-step explanation:
Coordinates of point R:
The coordinates of point R are , so (6,-7).
90° counterclockwise rule:
The rule for a rotation of 90º counterclockwise is given by:
(x,y) -> (-y,x)
What are the coordinates of point R?
(6,-7) -> (-(-7),6) = (7,6).
The coordinates of point R are (7,6), second option
Answer:
(-5,2)
Step-by-step explanation:
PLZ MARK ME BRAINLIEST
To find the solution to the system of equations, just find where the lines intersect. Since they intersect at (-5,2), the solution is (-5,2)
