The total number boxes of juice are 768 in the display.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We have been given that in each variety pack of fruit juice, there are 3 voxes of apple juice, 2 boxes of grape juice, and 1 box of orange juice.
In a display in the store, there are 16 cases of juice with 8 variety packs in each case therefore,
Each variety pack of fruit juice = 3 + 2 + 1 = 6 juice
8 variety packs = 8 x 6 = 48
Now, the total number boxes of juice are in the display
16 x 48
= 768

At a certain college, the probability that a student attends full-time is 0.320 and the probability that the student attends part-time is 0.680. At the same college, the probability that a student receives financial aid is 0.570 while the probability that a student does not receive financial aid is 0.430. If a student is randomly selected, what is the probability that the student attends full-time and does not receive financial aid?
the probability that a randomly selected student attends full-time and does not receive financial aid is ( 0.1376 ), or ( 13.76% ).
To find the probability that a student attends full-time and does not receive financial aid, we can use the multiplication rule for independent events.
Given:
- Probability of attending full-time: [tex]\( P(\text{full-time}) = 0.320 \)[/tex]
- Probability of not receiving financial aid:[tex]\( P(\text{no financial aid}) = 0.430 \)[/tex]
By the multiplication rule, the probability of both events occurring is the product of their individual probabilities:
[tex]\[ P(\text{full-time and no financial aid}) = P(\text{full-time}) \times P(\text{no financial aid}) \][/tex]
[tex]\[ = 0.320 \times 0.430 \][/tex]
[tex]\[ = 0.1376 \][/tex]
Therefore, the probability that a randomly selected student attends full-time and does not receive financial aid is ( 0.1376 ), or ( 13.76% ).

The number of cases of a new disease can be modeled by the quadratic regression equation y = –2x2 + 36x + 6, where x represents the year.
Which is the best prediction for the number of new cases in year 15?
A. 194
B. 96
C. 328
D. 614
Answer: B 96
Step-by-step explanation:
By evaluating the function in x = 15, we will see that in the year 15 there will be 96 cases.
Which is the best prediction for the number of new cases in year 15?
The function that predicts the number of cases in the year x is given by:
[tex]y = -2x^2 + 36x + 6[/tex]
So we just need to evaluate that function in x = 15, this means replacing x by 15.
[tex]y = -2*15^2 + 36*15 + 6 = 96[/tex]
So we can expect that in the year 15, there will be around 96 cases. Then the correct option is B.

Step-by-step explanation:
we know that
An isosceles triangle has two equal angles and two equal sides. The two equal angles are the base angles and the third angle is the vertex angle
In this problem the base angles are angle B and angle C
so
m∠B=m∠C
substitute
[tex](5x+5)\°=(7x-25)\°[/tex]
[tex](7x-5x)\°=(5+25)\°[/tex]
[tex]2x=30\°[/tex]
[tex]x=15\°[/tex]
m∠B=[tex](5x+5)\°=5*15+5=80\°[/tex]

Henry invest 4500 at a compound interest rate of 5% per annum. At the end of n complete years the investment has grown to 5469.78. Find the value of n
The value of n is 4. This means that it took 4 years for the investment to grow to £5469.78.
How to calculate the value of nWe can use the compound interest formula to solve this problem:
A = P(1 + r/n)nt
where:
A is the future value of the investment
P is the principal amount invested
r is the annual interest rate
n is the number of times per year the interest is compounded
t is the number of years
In this problem, we have the following information:
A = 5469.78
P = 4500
r = 0.05 (5%)
n = ?
t = n
We can plug these values into the formula and solve for n:
5469.78 = 4500(1 + 0.05/n)n
1.2155066 = (1.05)n
n = 4
Therefore, the value of n is 4. This means that it took 4 years for the investment to grow to £5469.78.

a graduated cylinder is filled to 41.5 ml with water and a piece of granite is placed in the cylinder displacing the level to 47.6 ml what is the volume of the granite piece in cubic centimeters?
The volume of the piece of granite is 6.1 cubic cm if the graduated cylinder is filled to 41.5 ml with water and a piece of granite is placed in the cylinder, displacing the level to 47.6 ml.
What is volume?
It is defined as a three-dimensional space enclosed by an object or thing.
We have:
Volume of the water filled in the cylinder = 41.5 ml
Volume after placing the piece of granite = 47.6 ml
The volume of the piece of granite = 47.6 - 41.5 = 6.1 ml
As we know 1 ml = 1 cm³
The volume of the piece of granite = 6.1 cubic cm
Thus, the volume of the piece of granite is 6.1 cubic cm if the graduated cylinder is filled to 41.5 ml with water and a piece of granite is placed in the cylinder displacing the level to 47.6 ml.

If you know that a < b, and both a and b are positive numbers, then what must be true about the relationship between the opposites of these numbers? Explain.
Answer: just copy and paste
We want to find the relationship between the opposites of a and b, given that both are positive and a < b.
That relation is:
-a > -b.
Remeber that the opposite of a real number is just -1 times that number.
The opposite of a is: -a
The opposite of b is: -b
Remember that for negative numbers, the closer the number is to zero, the larger is the number.
Because we know that a and b are positive, and a < b, then we know that a is closer to zero.
So for -a and -b, we know that -a is also closer to zero (then -a is larger than -b), so the relationship between these two is:
-a > -b.
When a < b and both a and b are positive numbers, the opposites of these numbers will have opposite signs.
Explanation:In mathematical terms, when two positive numbers add, the answer has a positive sign. Similarly, when two negative numbers add, the answer has a negative sign. However, when a negative number is added to a positive number, the answer will depend on the magnitudes of the numbers:
If the positive number is greater than the negative number, the answer will have a positive sign.If the positive number is smaller than the negative number, the answer will have a negative sign.So, in the given scenario where a < b, if both a and b are positive numbers, the opposites of these numbers will have opposite signs.

(4) use the method of lagrange multipliers to determine the maximum value of f(x, y) = x a y b (the a and b are two fixed positive constants) subject to the constraint x + y = 1. (assume x, y > 0.)
The maximum value of [tex]\(f(x, y)\)[/tex] is given by:
[tex]\(f\left(\frac{b}{a+b}, \frac{a}{a+b}\right) = \left(\frac{b}{a+b}\right)^a \left(\frac{a}{a+b}\right)^b\)[/tex]
To find the maximum value of the function [tex]\(f(x, y) = x^a y^b\)[/tex] subject to the constraint (x + y = 1, use the method of Lagrange multipliers.
Let's set up the Lagrangian function:
[tex]\(L(x, y, \lambda) = x^a y^b + \lambda(x + y - 1)\)[/tex]
Taking the partial derivatives and setting them to zero:
Equation 1: [tex]\(\frac{\partial L}{\partial x} = a x^{a-1} y^b + \lambda = 0\)[/tex]
Equation 2: [tex]\(\frac{\partial L}{\partial y} = b x^a y^{b-1} + \lambda = 0\)[/tex]
Equation 3: [tex]\(\frac{\partial L}{\partial \lambda} = x + y - 1 = 0\)[/tex]
From equations (1) and (2) it can be written as
Equation 4: [tex]\(a x^{a-1} y^b = -\lambda\)[/tex] ... (4)
Equation 5: [tex]\(b x^a y^{b-1} = -\lambda\)[/tex] ... (5)
Dividing equation (4) by equation (5) gives
[tex]\(\frac{a}{b} \frac{x^{a-1}}{x^a} \frac{y^b}{y^{b-1}} = 1\)[/tex]
[tex]\(\frac{a}{b} \frac{y}{x} = 1\)[/tex]
From equation (3) [tex]\(y = 1 - x\)[/tex].
Substituting [tex]\(y = 1 - x\)[/tex] into the equation [tex]\(\frac{a}{b} \frac{y}{x} = 1\)[/tex]
[tex]\(\frac{a}{b} \frac{1-x}{x} = 1\)[/tex]
[tex]\(a x = b (1-x)\)[/tex]
[tex]\((a + b) x = b\)[/tex]
[tex]\(x = \frac{b}{a+b}\)[/tex]
Substituting [tex]\(x = \frac{b}{a+b}\)[/tex] into the constraint equation (3):
[tex]\(y = 1 - x[/tex]
[tex]= 1 - \frac{b}{a+b} = \frac{a}{a+b}\)[/tex]
Therefore, the critical point (x, y) that satisfies the constraint equation is:
[tex]\(x = \frac{b}{a+b}\) and \(y = \frac{a}{a+b}\)[/tex]
Therefore, the critical point gives the maximum value of the function [tex]\(f(x, y) = x^a y^b\)[/tex] subject to the constraint x + y = 1.
