Given:
We get the points (0,6), (3,32), and (12,770) from the given table.
1.
Let y be the number of the rabbit and x be the number of months.
Consider the regression equation of the form.
Substitue x=0 and y=6 in the equation, we get
Substitue x=12 and y=770 in the equation, we get
![b^{}=\sqrt[3]{\frac{309}{32}}](https://tex.z-dn.net/?f=b%5E%7B%7D%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B309%7D%7B32%7D%7D)
Answer:
Dimension of room = 18 foot x 18 foot
Step-by-step explanation:
Let the square room is of side a foot,
The cost of re-finishing the hardwood floors is $2.25 per square foot and the cost of purchasing and installing the new baseboards $14.5 per linear foot
Total cost is $1773.
Cost for re-finishing the hardwood floors = Area x 2.25
Area = a²
Cost for re-finishing the hardwood floors = 2.25 a²
Cost of purchasing and installing the new baseboards = Perimeter x 14.5
Perimeter = 4a
Cost of purchasing and installing the new baseboards = 4a x 14.5 = 58 a
Total cost = Cost for re-finishing the hardwood floors + Cost of purchasing and installing the new baseboards
1773 = 2.25 a² + 58a
2.25 a² + 58a - 1773 = 0
a = 18 or a = -43.77(not possible)
Dimension of room = 18 foot x 18 foot
6x5=30
3x10=30
6+3=9

Answer:
C
Step-by-step explanation:
In option c, the first block is divided into 3 pieces where 2 parts are shaded whereas the second block is divided into 6 pieces where 3 parts are shaded
For both to be equivalent, both of them should be the same
2/3 = x/6
x = 4
4 pieces should be shaded in in the second block to be equal to the first one, in the diagram only 3 parts are shaded thus the answer is c
