Expression : 3 x 12 months=36 +5 rabbits her already had =41
Answer:
0.568516
Step-by-step explanation:
To find the the Coefficient of determination you simply square r.
Just make sure you have the original r value and not the rounded value.
0.754^2 = 0.568516
and then depending on how many decimals you need to round to...
Answer: 24, 33
2.5, 4.75
9.5, 11.75
<u>Step-by-step explanation:</u>
It is given that the PERIMETER is BETWEEN 24 and 33
--> 24 < P < 33
Graph: O------------------O
24 33
Perimeter = 2w + 2L
It is given that L = w + 7
Substitute P with 2w + 2L and substitute L with w + 7
24 < 2w + 2(w + 7) < 33
24 < 2w + 2w + 14 < 33
10 < 4w < 19
--> 2.5 < w < 4.75
Graph: O--------------------------O
2.5 4.75
Since L = w + 7, then w = L - 7
Substitute P with 2w + 2L and substitute w with L - 7
24 < 2(L - 7) + 2L < 33
24 < 2L + 2L - 14 < 33
38 < 4L < 47
--> 9.5 < L < 11.75
Graph: O------------------------O
9.5 11.75

Answer:
- (x, T) = (x, D) = (1000, 85)
- each booth pays $85 in fees on rental and sales of $1000
Step-by-step explanation:
A. <u>Given</u>
T = 0.05x +35 . . . . Terri's cost of operating a craft booth
D = 0.03x +55 . . . . Donna's cost of operating a craft boot
T = D
where x is the dollar amount of sales.
__
B. <u>Solution</u>
Subtracting the equation for D from that of T, we get ...
T - D = 0
(0.05x +35) -(0.03x +55) = 0 = 0.02x -20
0 = x -1000 . . . . . divide by 0.02
x = 1000
T = D = 0.05(1000) +35 = 85
(x, T) = (x, D) = (1000, 85)
__
C. <u>Meaning</u>
According to the given definitions of the variables, each booth pays a total of $85 in fees for sales of $1000.
