Answer:
Step-by-step explanation:
To determine which option is the better buy, we need to compare the price per unit (in this case, the price per cup or per gallon) of the two options.
For the 2-gallon bucket of paint that costs $88.00, the price per gallon can be calculated as:
$88.00 / 2 gallons = $44.00 per gallon
For the 37-cup bucket of paint that costs $90.28, we first need to convert cups to gallons. There are 16 cups in a gallon, so a 37-cup bucket contains:
37 cups / 16 cups per gallon = 2.31 gallons
The price per gallon can then be calculated as:
$90.28 / 2.31 gallons = $39.10 per gallon
Therefore, the 37-cup bucket of paint for $90.28 is the better buy, as the price per gallon is lower at $39.10, compared to $44.00 per gallon for the 2-gallon bucket.

Answer:
Exponential Function
General form of an exponential function with base \(e\):
\(f(x)=Ae^{kx}\)
where:
A is the y-intercepte (Euler's number) is the basek is some constantQuestion 30The curve crosses the y-axis at y = 40. Therefore, A = 40.
Substitute the found value of A into the formula along with (1, 56) and solve for \(k\):
\(\begin{aligned}f(x) & =Ae^{kx}\\\implies 56 & =(40)e^{k}\\e^k & =\dfrac{56}{40}\\k & =\ln (1.4)\end{aligned}\)
\(\textsf{Equation}: \quad f(x)=40e^{x\ln 1.4}\)
To find the population in 10 years, substitute \(x = 10\) into the found equation:
\(\begin{aligned}\implies f(10)&=40e^{10\ln 1.4}\\ & =1157.01862\\ & =1157\end{aligned}\)
Question 31The curve crosses the y-axis at y = 10. Therefore, A = 10.
Substitute the found value of A into the formula along with (1, 18) and solve for \(k\):
\(\begin{aligned}f(x) & =Ae^{kx}\\\implies 18 & =(10)e^{k}\\e^k & =\dfrac{18}{10}\\k & =\ln (1.8)\end{aligned}\)
\(\textsf{Equation}: \quad f(x)=10e^{x\ln 1.8}\)
To find the population in 8 years, substitute \(x = 8\) into the found equation:
\(\begin{aligned}\implies f(8)&=10e^{8\ln 1.8}\\ & =1101.996058\\ & =1102\end{aligned}\)

A certain brand of nuts costs $6.99 for 15.4 ounces. What is the unit rate? Enter your answer, rounded to the nearest cent, in the box.
The required unit rate for the nuts is $0.45/oz.(rounded to the nearest cent).
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
here,
The unit rate for the nuts can be found by dividing the total cost by the total weight,
Unit rate = total cost / total weight
Unit rate = $6.99 / 15.4 oz
Unit rate = $0.45/oz (rounded to the nearest cent)
Therefore, the unit rate for the nuts is $0.45/oz (rounded to the nearest cent).

How many ounces of pure alcohol should be added to 500 ounces of 35 % alcohol solution to produce a solution that is 50 %?
Pesent your answer as an integer or a reduced fraction. Do not use decimals.
Answer:
150 ounces
Step-by-step explanation:
It is convenient to write an equation for the total amount of alcohol in the mix.
__
Let x represent the amount of pure alcohol added. Then the amount of alcohol in the mix is ...
500(35%) +x(100%) = (500 +x)(50%)
x = 500(15%) +x(50%) . . . . . . . subtract 500(35%)
x(50%) = 500(15%) . . . . . . . . . . subtract x(50%)
x = (500)(15%)/(50%) = 150 . . . . divide by the coefficient of x
150 ounces of pure alcohol should be added to produce the desired solution.

In each of 10 and 11, show that the given system has no periodic solutions other than constant solutions. dx dt = 2x 3y xy2, dy dt = y + x3 x2 y
The system does not have a periodic solution in each of 10 and 11.
A solution of the period depends on the independent variable t is called Periodic Solution. For a periodic solution x(t)( in the case of a system, x is a vector), there is a number T≠0 such that
x(t+T)=x(t) for t∈R.
The given equations are:

The probability of 3 or more deaf people in a sample of 100 is given as follows:
0.3633 = 36.33%.
What is the binomial distribution formula?The mass probability formula, giving the probability of x successes, is of:
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
The parameters are given by:
n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.The values of the parameters for this problem are given as follows:
p = 0.02, n = 100.
The probability of 3 or more deaf people are given as follows:
P(X >= 3) = 1 - P(X < 3).
In which:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2).
Hence:
P(X = 0) = 0.98^100 = 0.1326.P(X = 1) = 100 x 0.02 x 0.98^99 = 0.2707.P(X = 2) = 99 x 50 x 0.02² x 0.98^98 = 0.2334.Thus:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)
P(X < 3) = 0.1326 + 0.2707 + 0.2334
P(X < 3) = 0.6367.
P(X >= 3) = 1 - P(X < 3).
P(X >= 3) = 1 - 0.6367.
P(X >= 3) = 0.3633.
TranslationWe suppose that 2% of the population is deaf, and want to find the probability of 3 or more deaf people in a sample of 100.

25,078,746 people per year -------> given
so
Per month
Divide by 12
25,078,746/12=2,089,896 per month (rounded to a whole number)
Per day
1 year=365 days
so
25,078,746/365=68,709 per day
Per hour
1 day=24 hours
so
68,709/24=2,863 per hour

The midpoint of segment AB is M(-2,2). If A is located at (-5,7) find the coordinates of the endpoint B
Answer:
B (1, -3)
Step-by-step explanation:
Step 1: Use the midpoint formula to find the coordinates of the endpoint:
Normally, we find the midpoint of a segment using the midpoint formula, which is given by:
M = (x1 + x2) / 2, (y1 + y2) / 2, where
M is the midpoint,(x1, y1) are one endpoint on the segment,and (x2, y2) are the other endpoint of the segment.Since we're solving for the coordinates of an endpoint, we can allow (-5, 7) to be our (x1, y1) point and plug in (-2, 2) for M to find (x2, y2), the coordinates of the endpoint B:
x-coordinate of B:
x-coordinate of midpoint = (x1 + x2) / 2
(-2 = (-5 + x2) / 2) * 2
(-4 = -5 + x2) + 5
1 = x2
Thus, the x-coordinate of the endpoint B is 1.
y-coordinate of B:
y-coordinate of midpoint = (y1 + y2) / 2
(2 = (7 + x2) / 2) * 2
(4 = 7 + x2) -7
-3 = y2
Thus, the y-coordinate of the endpoint B is -3.
Thus, the coordinates of the endpoint B are (1, -3).

Dividing the sum of (7/8) (15/4) (1/12) by their multiplication gives _________
The Division of the sum of (7/8), (15/4), and (1/12) by their multiplication is (2712/168).
To find the division of the sum of (7/8), (15/4), and (1/12) by their multiplication, we first need to calculate the sum and multiplication of the given fractions.
The sum of the fractions is:
(7/8) + (15/4) + (1/12)
To add these fractions, we need a common denominator. The least common multiple of 8, 4, and 12 is 24. Let's convert each fraction to have a denominator of 24:
(7/8) = (21/24)
(15/4) = (90/24)
(1/12) = (2/24)
Now we can add the fractions:
(21/24) + (90/24) + (2/24) = (113/24)
The multiplication of the fractions is:
(7/8) * (15/4) * (1/12)
To multiply fractions, we multiply the numerators and denominators:
(7*15*1) / (8*4*12) = (7/96)
Now we can divide the sum of the fractions by their multiplication:
(113/24) / (7/96)
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:
(113/24) * (96/7) = (2712/168)
Therefore, the division of the sum of (7/8), (15/4), and (1/12) by their multiplication is (2712/168).
