Answer:
Z = 0.75x + 0.25y
Step-by-step explanation:
Two bear types are identified :
Black bears and Grizzly bears
9 out of 12 = black bears ; Hence, 3 are grizzled
For the model:
For a bear population of Number x
Total bear population = black bear, x + grizzled bear, y
Proportion of black bear = 9/ 12 = 0.75
Grizzled bear = 1 - 0.75 = 0.25
Total bear population , Z= 0.75x + 0.25y
Hence,
Z = 0.75x + 0.25y
Answer:
x= 6
y= 2
Step-by-step explanation:
conversion factor is 2, so you have to divide by 2 in order to get your answers :)
It should be 986m
4(17x6)= 408
2(17x17)= 578
408+578=986
4117 to nearest 100 = 4100
