Answer:
$30+$10+$95+$7
Step-by-step explanation:
It asks for an expression (Equation) not an answer. The question wants you to show HOW to get the answer, NOT to write the equation AND solve it.

Answer:
Step-by-step explanation:
So bascially decay means shrinks or shrivels. Growth means like growing, bigger, sort of like a happy plant :D.
To find if this is getting bigger or is shrinking, lets plug in something simple like 1 for the time(t). Sooo:
20,000*.88^1
Since its a 1 exponent it does nothing so:
20,000*.88
Now this is 17600 you can use calculator but if you do this in head like me all I did is multiply 88 by 2 which was simply since 8 times 2 is 16 so 160+16 is 176 then I added zeros:
y=17600
As we can see this is smaller than 20,000, so it is a decaying problem.
By what percent tho.
Well this is pretty easy to reconize once you understand where to find it.
When they talk about percentage, they mean how much it decreased by.
This is 100%-the multiplyied value.
In this case the multiplyed value is 0.88, sooo:
100%-88%=18%
So the percent amount that the value decreased by is 18%.
Hope this helps!
Midpoint formula =
M = ( X1 + X2) divided by 2 , (Y1 + Y2) divided by 2 = m=(x ,y)
So then, we plug in our numbers .
M= (3+ -9)/2 , (7+3)/2
M= (-3, 5)
Complete Question
The model that describes the number of bacteria in a culture after t days has just been updated from to What implications can you draw from this information?
A The growth rate of the bacteria in the culture is 30% per day instead of
20% per day.
B The final number of bacteria is 3 times as much of the initial value instead
of 2 times as much.
C The initial number of bacteria is 3 instead of 2
D The number of bacteria triples every day instead of doubling every day
E None of the above.
Answer:
The correct option is D
Step-by-step explanation:
From the question we are told that
The first model is
The updated model is
Generally looking the two models that define the number of bacteria we see that at the for the first model that the number is being doubled everyday for example if the time is equal to 1 day we have that
Here we see that the constant 7 is being double but in the new model we can see that the number is being triple everyday , taking the same example with t = 1
=>
Here we see that the constant 7 is being triple for each day
Hence the implication of the model change is that the number of bacteria will be tripled everyday instead of being doubled everyday
Answer:
6/7 or 85.7 percent
Step-by-step explanation:
First, you will want to add all of the candies together and find the sum
Then you will want to take away the Lemon candies as you are looking for the probability of NOT choosing those,
so at this point, you should have 12 take that 12, and put it over the total number, so 12/14 then either simplify, or switch to a percentage, or both, and there is your answer.
