Answer:
a = 1500
b = 0.97
Step-by-step explanation:
Let's define 2014 as our t = 0.
Then t = 1 will be 2015, and so on.
We know that in 2014 the population was 1500.
It decreases at an annual rate of 3% or 0.03 in decimal form.
Then in 2015, the population was: 1500 - 1500*0.03 = 1500*(0.97)
In 2016, the population was: 1500*(0.97) - 1500*(0.97)*0.03 = 1500*(0.97)^2
We already can see the pattern.
t years after 2014, the population will be:
f(t) = 1500*(0.97)^t
Now, answering the question:
using f(t)=a(b)^t what is the value of a and b?
a = 1500
b = 0.97

The residual for a predicted relative abundance when the rainfall was 3 inches is 1.25. What is the actual relative abundance when the rainfall was 3 inches
Answer:
The actual relative abundance will be "7.59".
Step-by-step explanation:
The residual on something like a curve anywhere at a point becomes expressed as the maximum at either the position between some of the real y-value as well as the expected y-value. Consequently, the difference regarding true relative abundance as well as expected relative abundance seems to be 1.25 whether we presume that the x-variable represents rainfall, as well as they-variable, represents the relative abundance of locusts.The predicted relative abundance for 3 inches rainfall will be:
= [tex]6.7 - (0.12\times 3)[/tex]
= [tex]6.34[/tex]
The residual will be:
= [tex]actual - predicted \ relative \ abundance[/tex]
= [tex]1.25[/tex]
Now,
The actual relative abundance will be:
= [tex]1.25 + predicted \ relative \ abundance[/tex]
= [tex]1.25 + 6.34[/tex]
= [tex]7.59[/tex]
Remember that perhaps the residual positive value means that even the calculation underestimates the relative abundance. The real relative abundance, however, is 7.59.
Can someone factor f(x)= 2x^4 -12x^3 +6x +20x and please show steps thank you
Answer:
I dont think the way you wrote it was right.
Step-by-step explanation:
Answer:
f(x) = 2x(x - 5)(x -2)(x + 1)Step-by-step explanation:
Given
f(x)= 2x^4 -12x^3 +6x^2 +20xFactoring in steps
f(x)= 2x^4 -12x^3 +6x^2 +20x =2x(x^3 - 6x^2 + 3x + 10) =2x(x^3 - x^2 - 2x - 5x^2 + 5x + 10)2x(x - 5)( x^2 - x - 2) = 2x(x - 5)(x -2)(x + 1)help!! math question!

A right triangle has side 9 and hypotenuse 15. Use the Pythagorean Theorem to find the length of the third side.
Provide your answer below:
Answer:
12
Step-by-step explanation:
Pythogorean Theorem:
a squared + b squared = c squared
9 squared or 81 + ? squared = 15 squared or 225
Inverse Pythagorean Theorem:
c squared - a squared = b squared
225 - 81 = 144
sqrt (144) = 12
12 = b
Hope this helps! Good luck!

store A Sells a set for $26 and offers a 15% discount
Answer:
Step-by-step explanation:
20% of $1200 is $240
(0.2∗1200)=$240
Now subtract that number from 1200
1200−240=$960
try this example
Answer:
$22.10
Step-by-step explanation:
First you would multiply 26 by .15, which represents 15%, or 15/100. After you multiply, you will get 3.9. 3.9 represents the discount of the price. Since it is a discount, you suntract 3.9 from 26, and you get 22.1.

A = the future value of the investment
P = the principal investment amount
r = the interest rate (decimal)
n = the number of times that interest is compounded per period
t = the number of periods the money is invested for

In a random sample of 100 voters, 48 said they planned on voting for the Republican presidential candidate. On election day, 51% of voters actually voted for the Republican presidential candidate. (a) Identify the value of the sample proportion.
Answer: 0.48 .
Step-by-step explanation:
The sample proportion is a ratio of number of successes in a sample to the sample size.Let p be the proportion of voters actually voted for the Republican presidential candidate.
Given: In a random sample of 100 voters, 48 said they planned on voting for the Republican presidential candidate.
Sample proportion: [tex]\hat{p}=\dfrac{48}{100}=0.48[/tex]

Katie just opened a checking account at the bank. Within the first month, she deposited three checks for $21.68, $42.09, and $65.44. She withdrew $4.64 for new pencils, $23.11 for earbuds, and $9.78 for movies from her account in the same month.
Complete question is;
Katie just opened a checking account at the bank. Within the first month, she deposited three checks for $21.68, $42.09, and $65.44. She withdrew $4.64 for new pencils, $23.11 for earbuds, and $9.78 for movies from her account in the same month.
Write Katie’s withdrawals as negative rational numbers and her deposits as positive rational numbers.
Answer:
Deposits are; +21.68, +42.09, and +65.44.
Withdrawals are; -4.64, -23.11, and -9.78
Step-by-step explanation:
We are told that the deposits are;
$21.68, $42.09, and $65.44.
Now, she withdrew $4.64 for new pencils, $23.11 for earbuds, and $9.78 for movies from her account in the same month.
We are told to write Katie’s withdrawals as negative rational numbers and her deposits as positive rational numbers.
A rational number is a number that can be expressed as the ratio of two integers. In this question, by inspection, all the given values for deposits and withdrawals can be expressed as the ratio of 2 integers.
Thus;
Deposits are; +21.68, +42.09, and +65.44.
Withdrawals are; -4.64, -23.11, and -9.78
