he weight of a chimpanzee, y, in pounds, x months after birth is modeled by the equation y=1.5x+8. Which represents the equation
1 answer:
The equation that represents x when solved is
Given the equation that expresses the weight of a chimpanzee with respect to the months of birth as:
y = 1.5x + 8
We are to express x in terms of "y"
Subtract 8 from both sides
Divide both sides by 1.5
Hence the equation that represents x when solved is

Answer:
the x² test statistic 13.71
Option a) 13.71 is the correct answer.
Step-by-step explanation:
Given the data in the question;
Feeder 1 2 3 4
Observed visits; 60 90 92 58
data sample = 300
Expected = 300 / 4 = 75
the x² test statistic = ?
= ∑[ (
-
)²/
]
= [ (60 - 75)² / 75 ] + [ (90 - 75)² / 75 ] + [ (92 - 75)² / 75 ] + [ (58 - 75)² / 75 ]
= [ 3 ] + [ 3 ] + [ 3.8533 ] + [ 3.8533 ]
= 13.7066 ≈ 13.71
Therefore, the x² test statistic 13.71
Option a) 13.71 is the correct answer.
