Answer:
336 squirrels
Step-by-step explanation:
-This is a Mark-Recapture method.
-The population is estimated using the formula:
where:
- N-is the estimated population size.
- M-is the number of individuals tagged
- C- is the total number captured the second time(both tagged and untagged)
- R-is the total number of tagged individuals recaptured.
#We substitute our values as follows to estimate N:
Hence, there are approximately 336 squirrels in the conservation area.
*population is always rounded up to the next whole number.
Answer: 40
Step-by-step explanation:
Assume Julio's number is x.
The expression would be:
-7 * (x - 15) = -175
x - 15 = -175/-7
x = -175/-7 + 15
x = 40
Answer:
m+g
40
12m + 14g
250
Step-by-step explanation:
Jordan is paid $12 per hour for mowing lawns and $14 per hour for planting gardens.
Let m represents the number of hours mowing lawns and g represents the number of hours planting gardens.
He can work a maximum of 40 hours per week, and would like to earn at least $250 this week.
Then, the system of the inequality becomes
m+g40
12m + 14g250
Answer: y=-x+7
Step-by-step explanation:
Answer:
Your given points: (9,-2)and (1,6)
x1=9
y1=-2
x2=1
y2=6
Step-by-step explanation:
To find slope take the points you got from graph and put it into the equation y2-y1/x2-x1
6-(-2)/1-9=6+2/1-9=8/-8=-1
SLOPE IS m=-1
Then take that slope u got and plug into this equation to find equation of the line
y-y1=m(x-x1)
y-(-2)=-1(x-9)
y+2=-x+9
-2. -2

y=-x+7 ANSWER CHECK
Answer:
8b
Step-by-step explanation:
'8 times b' symbolizes 8 being multiplied by 'b'.
Times is a word associated with multiplying.
8 times b can be 8 * b or most ideally, 8b.
Hope this helps!
