Answer:I dont know if this is right but
A: 384 in.
B: 1040 in. = 86 ft
C: because the dimensions are multiplied by 26 inches, the perimeter for the actual flower bed is converted into feet.
Step-by-step explanation:
A: (8*2)+(12*2) = 384 in.
B: ((8*26)*2)+((12*26)*2) = 1040 in. = 86 ft.
Answer:
The coefficient of determination is: C. 0.43
Step-by-step explanation:
The provided information is:
SST = 140.58 and SSE = 80.42
The coefficient of determination 
is determined by formula:
Thus, coefficient of determination is closest to 0.43
Answer:
Hi,
Step-by-step explanation:
I don't know the name in Enghish but in French it is "une règle de 3"
(may be linear rule)
arc length= 2*π*r/360*100=50*π/9
area= π*r²*100/360=250*π/9
18-6=12
2/3=0.66
12/0.66=18.1
18 is the answer
Answer:
3, 14, and sqrt205.
2,9, and sqrt85.
Step-by-step explanation:
Check if they fit the Pythagoras theorem c^2 = a^2 + b^2:
3^2 = 9 , 14^2 = 196.
9 + 196 = 205 which is the square of sqrt205.
So this is a right angled triangle.
6^2 + 11^2 = 36 + 121
= 157 Not right-angled.
19^2 + 180^2 = 32761 Not right-angled.
3^2 + 19^2 = 370 Not right-angled.
2^2 + 9^2 = 85, So this is right angled..
