Answer:

Start: Brown feather % is 97% Grey feather % is 3%

End: Brown feather % is 19% Grey feather % is 81%

Step-by-step explanation:

Start:

There is 700 total feather (679+21) so to get to 100(the denominator for percentages) you have to divide by 7

divide each number by 7(679/7 and 21/7)

and you get 97 and 3 which will be your percentages

End:

There is 740 total feather (140+600) so to get to 100(the denominator for percentages) you have to divide by 7.4

divide each number by 7.7(140/7.4 and 600/7.4)

and you get about 19(rounded) and about 81(rounded) which will be your percentages

Hope this helps!!!

AURORKA [14]

The change of population per year is 1,900

We'll start by subtracting; 41,600-24,500= 17,100
Then we'll divide 17,100 by 9 because there is a 9 year difference between 2003 and 2012.

Dan bought a truck for $29,800. The value of the truck depreciated at a constant rate per year. The table shows the value of the

leonid [27]

Answer:

A) f(t) = 29,800(0.89)^t

Step-by-step explanation:The truck value decreases by 11% each year.

The present value of the truck was $29,800.

29,800 x 0.11 = 3,728 dollars lost from value.

29,800 - 3,728 = 26,522, the value of the truck after one year.

26,522 x 0.11 = 2,917.42 cash lost from value.

26,522 - 3,728 = 23,604.58, the value of the truck after two years.

Therefore, the answer is A) f(t) = 29,800(0.89)^t.

Which of these are propositions? What are the truth values of those that are propositions?

Natasha2012 [34]

Answer:

c) There are no black flies in Maine -> False

e) The moon is made of green cheese -> False

Explanation:

A proposition is a statement that poses an idea that can be True or False.

Do not pass go, is not a proposition is an order, and there is not an answer to that statement.
What time is it? Is not a proposition is a question and it's response goes beyond True or False.
There are no black flies in Maine is indeed a proposition because is a statement that can either be True or False.

4 + x = 5 is not a proposition because is a statement with an infinite number of answers, in contrast, 4 + 1 = 5 is a proposition because is either True or False.
The moon is made of green cheese is a proposition because is a statement that can either be True or False.
2 n ≥ 100 is not a proposition because is a statement with an infinity number of answer and is not clear whether is True or False, in contrast, 2 ≥ 100 is a proposition because is either True or False.

Aleks [24]

Answer: Relative error = 50%

Step-by-step explanation:

Relative error Re = Absolute error/True value × 100%

True value = 2 scoops

Measured(used) value = 3 scoops

Absolute error Ae = measured(used) value - True value

= 3 scoops - 2 scoops

Ae = 1 scoop

Re = 1/2 × 100%

Re = 50%

-3m-1<-10 or -4+2m<-14

Liono4ka [1.6K]

Answer:

m>3 or m<-5

Step-by-step explanation:

First simplify -3m-1 < -10:

-3m < -9

m > 3 (switch direction of sign when dividing by negative number)

Then simplify -4+2m<-14:

2m<-10

m<-5

m>3 or m<-5
