Answer:
The volume of water in the pool over time from when the hose is placed in the pool until the pool is full is defined by the equation and its graph is given below.
Explanation:
The total capacity of the pool is 20,000 gallon.
It is given that the pool contains 5000 gallons of water when a hose is placed in the pool and begins adding water at a rate of 1250 gallons per hour. So the initial volume of water is 5000.
Let the time is defined by t. So, the volume of water in the pool after time t is defined as,
The capacity of the pool is 20,000 gallon, therefore the maximum value of V(t) is 20,000.
The maximum value of t is 12, since the time is always positive, therefore we can say that,
The below graph representing the volume of water in the pool over time from when the hose is placed in the pool until the pool is full. The initial point is (0,5000) and the other point is (12,20000).
Answer:
the two points will be (0,5000) and (12,20000

Step-by-step explanation:
The area of a kite can be identified through 1 / 2 of the multiplication of each diagonal. The first diagonal is equivalent to the addition of 50 cm and 10 cm, while the second is of length 20 cm + 20 cm.
\(1 / 2 * ( 50 + 10 ) * ( 20 + 20 ),\\1 / 2 * ( 60 ) * ( 40 ),\\( 30 ) * ( 40 ),\\\\Area of Kite = 1200 square cm\)
Consider the first option. If we take a look at the bit 2 * ( 1 / 2 * 20 * 50 ) the 2 and 1 /2 cancel each other out, leaving you with 20 * 50 = 1000 . Respectively in the expression 2 * ( 1 / 2 * 20 * 10 ) the 2 and 1 / 2 cancel each other out, leaving you with 20 * 10 = 200;
\(1000 + 200 = 1200 square cm,\\Option A - Correct!\)
The second option considers the expression 2 * ( 1 / 2 * 20 * 60 ). Again, the 2 and 1 / 2 cancel each other out, leaving you with 20 * 60;
\(20 * 60 = 1200 square cm,\\Option B - Correct!\)
Option C is a similar version of option a, besides the fact that the 1 / 2 doesn't exist. Thus, Option C is incorrect!
Option D is a similar version of option a as well, but as the 2 doesn't exist, it is incorrect!
This last option, option E is taken as 1 / 2 of the multiplication of the diagonals, and thus is correct!
\(1 / 2 * ( 40 * 60 ),\\1 / 2 * ( 2400 ),\\1200 square cm\\\\Correct!\)
Suppose that a loan of $5500 is given at an interest rate of %6 compounded each year. Assume that no payments are made on the loan.
Answer:
Step-by-step explanation:
The formula for annual compound interest, including principal sum, is:
A = P (1 + r/n) (nt)
where
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested or borrowed for
here
we have to found semianually
P= 2000
r= 11% =0.11
n=2 .... for semiannual
t =5
A = 2000( 1 +0.11 /2 )(2*5)
= 2000(1 +0.055)10
= 2000(1.055)10
= 2000(1.708)

we 1st can get the weight of rat by
1 rat and 1 cat + 1 dog and rat = 30
2 rat + 1 cat + 1 dog = 30
Then 1 rat and cat measure 24 so
2 rat + 24 =30
2 rat + 24 =30 1 rat = 3 kg
2 rat + 24 =30 1 rat = 3 kg 1 cat + 1 rat = 10
2 rat + 24 =30 1 rat = 3 kg 1 cat + 1 rat = 101 cat + 3kg = 10
2 rat + 24 =30 1 rat = 3 kg 1 cat + 1 rat = 101 cat + 3kg = 101 cat = 7kg and
2 rat + 24 =30 1 rat = 3 kg 1 cat + 1 rat = 101 cat + 3kg = 101 cat = 7kg and 1 dog + 1 rat = 20 kg
2 rat + 24 =30 1 rat = 3 kg 1 cat + 1 rat = 101 cat + 3kg = 101 cat = 7kg and 1 dog + 1 rat = 20 kg 1 dog + 3kg = 20 kg
2 rat + 24 =30 1 rat = 3 kg 1 cat + 1 rat = 101 cat + 3kg = 101 cat = 7kg and 1 dog + 1 rat = 20 kg 1 dog + 3kg = 20 kg 1 dog = 17kg
so we get the weight of each now we r going to sum them 1 rat + 1 cat + 1 dog = x
1 rat + 1 cat + 1 dog = x 3 kg + 7 kg + 17 kg = x

A car traveled 180 miles at a constant rate. Write an equation that would
make it easy to find the rate at which the car was traveling in miles per
hour r, if it traveled for t hours.
Answer:
180/t = r
Step-by-step explanation:
In this question, we would have to write an equation that represents the scenario given.
We know that the car traveled 180 miles at a constant rate.
We would use the y = mx + b format for the equation, but replacing the variables with "r" and "t"
We know that 180 will be our y-variable, since that would be the base of the equation:
180 = ???
And to find how long/fast it will take the car, we would need to multiply the rate of speed "r" and time "t" in order to get our distance.
Plug it into the equation:
180 = rt
With this set up, you can find the rate of speed of the car when you know the time.
You would simply solve it as:
180/t = r

B. 54 miles
C. 346.5 miles
D. 292.5 miles

The mean exam score for 49 male high school students is 239 and the population standard deviation is 47 The mean exam score for 53 female high school students is 21.1 and the population standard deviation is 4.3.

Click here to view. page 2 of the standard normal distribution table. A. Male high school students have lower exam scores than female students B. Male and temale high school students have different exam scores. C. Male and female high school students have equal exam scores D. Male high school students have greater exam scores than female students
Comparing the means of the two samples, we find that the difference between the means is significant. Therefore, we can reject the claim and conclude that male and female high school students have different exam scores.
To perform the two-sample t-test, we first calculate the standard error of the difference between the means using the formula:
SE = sqrt((s1^2 / n1) + (s2^2 / n2))
Where s1 and s2 are the population standard deviations of the male and female students respectively, and n1 and n2 are the sample sizes. Plugging in the values, we have:
SE = sqrt((47^2 / 49) + (4.3^2 / 53))
Next, we calculate the t-statistic using the formula:
t = (x1 - x2) / SE
Where x1 and x2 are the sample means. Plugging in the values, we have:
t = (239 - 21.1) / SE
We can then compare the t-value to the critical t-value at α = 0.01 with degrees of freedom equal to the sum of the sample sizes minus 2. If the t-value exceeds the critical t-value, we reject the null hypothesis.
In this case, the t-value is calculated and compared to the critical t-value using the provided standard normal distribution table. Since the t-value exceeds the critical t-value, we can reject the claim that male and female high school students have equal exam scores.
Therefore, the correct answer is:
B. Male and female high school students have different exam scores.

During the period from 2011 through 2015 the annual returns on small U.S. stocks were - 3.80 percent, 19.15 percent, 45.91 percent, 3.26 percent, and - 3.80 percent, respectively. What would a $1 investment, made at the beginning of 2011 , have been worth at the end of 2015 ? (Round answer to 3 decimol places, eg. 52.750.) Value in 2015$ What average annual return would have been earned on this investment? (Round answer to 2 decimai ploces, eg. 52.75) Average annual return percent per year:
The average annual return on this investment from 2011 to 2015 is approximately 0.8%.
To calculate the value of a $1 investment made at the beginning of 2011 and its average annual return by the end of 2015, we need to multiply the successive annual returns and calculate the cumulative value.
The successive annual returns on small U.S. stocks from 2011 to 2015 are:
-3.80%, 19.15%, 45.91%, 3.26%, and -3.80%.
To calculate the cumulative value, we multiply the successive returns by the initial investment value of $1:
(1 + (-3.80%/100)) * (1 + (19.15%/100)) * (1 + (45.91%/100)) * (1 + (3.26%/100)) * (1 + (-3.80%/100))
Calculating this expression, we find that the cumulative value is approximately $1.044, rounded to three decimal places.
Therefore, a $1 investment made at the beginning of 2011 would have been worth approximately $1.044 at the end of 2015.
To calculate the average annual return, we need to find the geometric mean of the annual returns. We can use the following formula:
Average annual return = (Cumulative value)^(1/number of years) - 1
In this case, the number of years is 5 (from 2011 to 2015).
Average annual return = (1.044)^(1/5) - 1
Calculating this expression, we find that the average annual return is approximately 0.008 or 0.8% per year, rounded to two decimal places.
Therefore, the average annual return on this investment from 2011 to 2015 is approximately 0.8%.

Victoria filled up her car with gas before embarking on a road trip across the country. The car uses 1.75 gallons of gas for every hour driven, and after driving for 4 hours, there were 7 gallons of gas left in the tank. Write an equation for G,G, in terms of t,t, representing the number of gallons of gas remaining in Victoria's gas tank after tt hours of driving.
Answer:
G = 14 - 1.75(t)
Where G is the number of gallons of gas remaining;
14 represents the amount of gas in gallons in the full gas tank of the vehicle
t is the number of hours
Step-by-step explanation:
Here, we want to write an equation.
We are told that the car uses 1.75 gallons of gas every hour and after 4 hours 7 gallons were left
In the 4 hours, the amount of fuel used will be 1.75 * 4 = 7 gallons
So therefore since we have 7 gallons left, the amount of gallons in the full tank of the vehicle will be 7 + 7 = 14 gallons
Hence, the equation we want to write will be;
G = 14 - 1.75(t)
A square with a perimeter of 20 inches is cut into 2 pieces, which are attached by their short ends to make a rectangle. What is the perimeter of this rectangle?
Answer:
25 inches
Step-by-step explanation:
If square has a perimeter of 20 inches, the length of each side is:
\(s=\frac{20}{4}\\ s=5\ in\)
After cutting the square in half, we are left with two rectangles of 5 in x 2.5 in
Attaching those two smaller rectangles by their short end (2.5 in side), gives us a new rectangle with a height of 2.5 in and a length of 10 in (sum of the 5 in sides in each rectangle). The perimeter of this new rectangle is:
\(P=2*2.5+2*10\\P=25\ in\)
The perimeter is 25 inches.

There are dependent and independent variables in statistical modeling, experimental sciences, and mathematical modeling. Dependent variables are so-called because, during an experiment, their values are assessed under the presumption or requirement that they are dependent on the values of other variables as a result of a certain law or rule (for example, a mathematical function). Independent variables are ones that are not seen as being reliant on any other variables in the context of the experiment in question.
Common independent variables that can be used to forecast include time, space, density, mass, fluid flow rate, and previous values of some observed value of interest (such the size of the human population).
