Answer:
x²+y²=16
Step-by-step explanation:
the general equation for a circle is given as :
(x−h)²+(y−k)²=r²
where (h, k) is the coordinate of the center of the circle and r is the radius
in this case h=0, k=0 and r = 4
equation becomes
x²+y²=4²
or
x²+y²=16
Given that Joseph earns $15 for every lawn he mows.
so if he mows lown 1 time then his earning = $15
if he mows lown 2 time then his earning = $15*2= $30
if he mows lown 3 time then his earning = $15*3= $45
if he mows lown 4 time then his earning = $15*4= $60
if he mows lown 5 time then his earning = $15*5= $75
So the required table will be:
From the table we can see that Joseph's earning increases by $15 each time so we can say that YES, the amount of money he earns proportional to the number of lawns he mows.

Answer:
56 students scored in the range of 1301 to 1600.
Step-by-step explanation:
The given question is without any figure or attachment. Here is the figure attached with the answer.
In the figure attached,
total number of students who took SAT = 400
Percentage of the students who scored 1301 to 1600 range = 14% (given in the pie chart)
Total number of students who are in this range = 14% of total number of students
= 
= 56
Therefore, 56 students scored in the range of 1301 to 1600.
