The area of a wetland is 10,000 acres. A biologist predicts that the area of the wetland will change according to the equation y equals 10000 left-parenthesis 0.65 right-parenthesis Superscript x Baseline, where y is the area of the wetland after x years. Based on the biologist's prediction, what will the area of the wetland be in 2 years?
Answer:
4,225 acresStep-by-step explanation:
If a biologist predicts that the area of the wetland will change according to the equation [tex]y = 10,000(0.65)^{x}[/tex] where;
y is the area of the wetland after x years
In order to determine the area of the wetland in 2 years based on the biologist prediction, we will substitute the value of x = 2 into the modeled equation as shown;
[tex]y = 10,000(0.65)^{2}\\y = 10,000 * 0.4225\\y = 4225[/tex]
The area of the wetland in 2 years based on the biologist prediction will be 4225 acres

Answer:
The age of the car in years is the independent variable
The average miles is the dependent variable
Step-by-step explanation:
Typically, the age of the car will have an affect on the number of miles per gallon. However, the number of miles per gallon will not make it gain or lose more years, so the age is independent because it does not depend on another variable.
Hope this makes sense :)

How to solve for x 2x + 3x -5 =20
Answer: x=5
Step-by-step explanation:
Simplify to 2x+ 3x -5 to 5x-5
5x- 5 = 20
Add 5 to both sides.
5x= 20+5
Simplify 20+5 to 25.
5x= 25
Divide both sides by 5.
x= 25/5
Simplify 25/5 to 5.
x=5

5) A bowl contains 6 tangerines and 4 apples. John randomly selects one piece of fruit, and then Pam randomly selects one of
the remaining pieces of fruit. What is the probability that John selects a tangerine and Pam selects an apple?
Pls help
Answer:5/18
Step-by-step explanation:
there are 9 pieces of fruit in the bowl, tangerines and 5 clementines.
Assuming that they do not put the fruit back
P (tangerine) = number of tangerines/ total = 4/9
Then John keeps his and there are 8 pieces of fruit in the bowl,
3 tangerines and 5 clementines.
P (Clementine) = number of clementines/ total = 5/8
P (tangerine, no replacement, Clementine) = P (tangerine) * P (Clementine)
= 4/9 * 5/8 =5/18
Plz help ASAP!! A surgical technique is performed on eight patients. You are told that there is an 80% chance of success. Find the probability that the surgery is successful for fewer than two patients. Please show your work. Hint: the answer is 0.000084.
Answer:
This is a fairly simple binomial distribution. We know it's binomial, because we're looking for a "fixed" number of patients, not the "first" like a geometric.
You can use your calculator:
binomcdf(n,p,Kr)
n=population, p=probability, Kr=number you're looking for
binomcdf(8,.8,1)
We have to do 1, not 2, because it says fewer than 2, which means 1.

The area of a square is 102 square units. What is an
estimated value for the length of a side of the square?
between 10 and 11
between 11 and 12
between 12 and 13
between 13 and 14
Answer:
Between 10 and 11.
Step-by-step explanation:
To begin, we can look at the problem as such. If we take the first answer choice, we can find the squares of both numbers giving us: (Remember that the area of a square is A=L²)
10²= 100
11²= 121
Since the given area is in between these two numbers, this means that the side length must be between 10 and 11.

This is a perfect square trinomial in the form a^2 - 2ab + b^2 = (a-b)^2. In this case, a = x and b = -3.
Another way you can look at it is to ask yourself "what two numbers multiply to 9 (last term) and add to -6 (middle coefficient)?". Those two numbers are -3 and -3
-3 plus -3 = -6
-3 times -3 = 9
So this is why x^2-6x+9 = (x-3)(x-3)
We can expand (x-3)(x-3) back out to get x^2-6x+9 again using the FOIL rule, distributive property, or the box method.
Answer:
C. (x-3)(x-3)
Step-by-step explanation:
x² - 6x + 9 = 0
x² - 3x - 3x + 9 = 0
x(x - 3) - 3(x - 3) = 0
(x - 3) (x - 3) = 0

The results of a survey indicate that the true proportion of households who recycle paper products
is likely in the interval (0.61,0.7).
What is the point estimate of the proportion of households who recycle paper?
Enter your answer, as a decimal, in the box.
Answer:
[tex] 0.61 \leq p \leq 0.70[/tex]
And for this case we can estimate the proportion of households who recycle paper is given by:
[tex] \hat p = \frac{Upper +Lower}{2}[/tex]
And replacing we got:
[tex] \hat p =\frac{0.7+0.61}{2}= 0.655[/tex]
And for this case the answer is 0.655 for the proportion of households who recycle paper
Step-by-step explanation:
For this case we know that the confidence interval for the proportion of interest is given by:
[tex]\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex]
And for this case the confidence interval is given:
[tex] 0.61 \leq p \leq 0.70[/tex]
And for this case we can estimate the proportion of households who recycle paper is given by:
[tex] \hat p = \frac{Upper +Lower}{2}[/tex]
And replacing we got:
[tex] \hat p =\frac{0.7+0.61}{2}= 0.655[/tex]
And for this case the answer is 0.655 for the proportion of households who recycle paper

The scale factor for this dilation is 2
What is dilation?The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger. The initial figure is referred to as the pre-image, and the new figure that results from dilatation is known as the image.
As per the given data:
We are given a diagram having 2 triangles, we need to find the scale factor for this dilation.
For finding the scale factor, we can find the ratio of the corresponding sides of the two triangles.
Scale factor for ΔG'H'I' and ΔGHI :
= [tex]\frac{H'I'}{HI}[/tex]
From the given graph, we can clearly observe that
H'I' = 8 + 4 = 12
HI = 4 + 2 = 6
[tex]\frac{H'I'}{HI}[/tex] = [tex]\frac{12}{6}[/tex] = 2
Hence, The scale factor for this dilation is 2.

A train travels at 45 miles per hour. Write and equation that represents the distance, d, that the train will travel, in t hours.
Answer:
d = 45 * t
Step-by-step explanation:
We know the equation as dert
distance equals rate * time
d = 45 * t
Answer:
d = 45 * t
Step-by-step explanation:
Step 1: Ok so for a. we can just need to build a equation representing the space the practice travels in t hours:
We can also recognize that it travels 45 mph, in order that is representing by 45(t).
d is the distance. So the equation is d = 45(t)
Step 2: For phase b. we change 2.5 with t a the equation. Then we solve it
d = 45(2.5)
45 * 2.5 = 112.5

A telescope costs $98. It is on sale for 35% off. What is the cost of the telescope after the discount?
Answer:
To solve this equation first we need to find out how much is 35% of $98.
The percentage of a number is found by multiplying the percentage by the number:
35% x $98 = $34.3
So the 35% off the telescope equals a discount of $34.30.
Now let’s find the price after the discount.
We need to subtract the discount price from the original price:
$98 - $34.30 = $63.70
So we know that the price of the telescope after the discount is $63.70

The amount of people in a population can be determined by using the model y=1000(1.35)x. What is the growth rate?
A.
35%
B.
1.035%
C.
1.35%
D.
3.5%
Answer:
The growth rate is 35%
Step-by-step explanation:
We are given that the amount of people in a population can be determined by using the model :
[tex]y=1000(1.35)^x[/tex]
Formula of exponential growth : [tex]y=a(1+r)^t ----1[/tex]
Where y is the population in t years
a = Initial population
r = growth rate
The given equation can be written as [tex]y=1000(1+0.35)^x[/tex]
Om comparing it with 1
r = 0.35
So, Growth rate = 35%
Hence The growth rate is 35%
