Answer:
A) T is located on (-5, 2); radius = 9 units
Step-by-step explanation:
eqn of circle= (x-a)^2 + (y-b)^2 = r^2
where (a,b) is centre of circle.
(x+5)^2 = (x - (-5) )^2
(y-2)^2 = (y - (2) )^2
(-5,2)
r^2 =81
r = sqrt of 81
r = 9
T=2M
W=T-6
M+T+W=19
M+2M+(T-6)=19
3M+(2M-6)=19
5M=19+6
5M=25
M=5
Answer:
$93.22
Step-by-step explanation:
bill = $79
tip = 18%
tip amount = tip % of bill
=18/100 * $79
=$1422/100
=$14.22
total cost = $79 + $14.22
=$93.22
Answer:
Median
Step-by-step explanation:
This is because if you used the mean it would be higher than the median because there is an outlier (78)
or
Because the data is skewed right, the mean would be affected
