Answer:
The answer to this problem is B, C, and E.
Step-by-step explanation:
Answer:
Row 2
Step-by-step explanation:
To find the mean, we add all the numbers and divide by the number of numbers
Row 1:
(6+5+3+0+4)/5 = 18/5 = 3.6
Row 2:
(4+5+3+5+6)/5 = 23/5 = 4.6
Row 3:
(7+1+4+5+3)/5 = 20/5 = 4.0
Row 4:
(4+2+5+6+3)/5 = 20/5 = 4.0
The greatest mean , or the largest mean is 4.6 or Row 2
Answer: It would take 9 hours for 4 painters to paint 720 feet of fence.
Step-by-step explanation:
1.) Calculate the time needed to paint the 720 ft fence with 2 painters.
a.) Divide 720 by 280 to get how many times greater 720 is than 280.
720 / 280 ≈ 2.57
b.) Multiply the time needed to paint the 280 ft fence with 2 painters by 2.57.
7 * 2.57 ≈ 18
2.) Calculate the time needed to paint the 720 ft fence with 4 painters.
a.) Assuming that each painter paints the same amount of fence, divide the time in half, as 4 painters is double the original amount, so it would take half of the time.
18 / 2 = 9
B. a rigid transformation was performed. Am I right or wrong?
y - 3 = x
x^2 - 6x + 13 = y
--
y = x + 3
x^2 - 6x + 13 = x + 3
x^2 - 7x + 10 = 0
x^2 - 5x - 2x + 10 = 0
x (x - 5) - 2 (x - 5) = 0
(x - 2) (x - 5) = 0
x = 2, or x = 5
The answers choices only have one solution where x = 2 or x = 5, so the answer is (2, 5).
