Jelly beans are $1.5/lb and trail mix is $2.063/lb, according to the data.

A heterogeneous mixture would be a trail mix. When the components of a combination are dispersed unevenly across the mixture, the mixture is said to be heterogeneous. As a mixture of nuts, raisins, and other seeds, trail mix cannot have an evenly distributed dispersion of its ingredients.

t = trail mix, j = jelly beans

3t + 8j = 21

5t + 2j = 18

Solving the first for t

2t = 6j - 3

t = (6j - 3)/2

Substituting

5(6j - 3)/2 + 2j = 18

j = 51/34

j = 1.5, Jelly beans cost $1.5/lb

now,

8t + 3(1.5) = 21

8t = 16.5

t = 2.0625, trailmix costs $2.063 dollars/lb

Answer: f(5)=9.5

Step-by-step explanation:

If the graph displays f(x)=(-1/2)x+12, then the answer for f(5) would be 9.5.

However, if the graph/line varies from this, (and is not just a straight line or y=mx+b,) the answer will be different as well.

Given the information you gave me though, this is the best I can do. Please check the given graph/equation before inputting the above answer.

The graph in this problem shows a proportional relationship, because the line passes through the origin, and the rate of change is of 40.

A proportional relationship is a special case of a linear function, with an intercept of zero.

The slope is the constant of proportionality, hence the proportional relationship has the equation defined as follows:

y = kx.

Hence the constant is given as follows:

k = y/x.

Two points from the graph are given as follows:

(1,40) and (2,80).

The constants for each point are given as follows:

The constants are the same for each point, hence the graph represents a proportional relationship.

What is triangle?

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

Given:

In ΔRST, m ∠R = (5x+15), m ∠S = (6x+8), m ∠T = (4x+7)

Since the addition of three angles of triangle is 180 degrees.

So,

          m ∠R + m ∠S + m ∠T = 180°

(5x + 15) + (6x + 8) + (4x + 7) = 180°

                               15x + 30 = 180°

                                       15x = 180° - 30°

                                       15x = 150°

                                           x = 10°

Hence, the value of x is 10°.

The maximum volume of the box in terms of A will be √3A/4 -3√3/4 cu cm.

It is given that the box has an open top and a square base.

This implies length = breadth.

Let them be x cm

Now, the area of the box is A sq cm

This means

lb + 2bh + 2lh = A

or, x² + 2xh + 2xh = A

or, 4xh + x² = A

or, h = A/4x - x/4

Now volume (V) = lbh

= x²(A/4x - x/4)

= Ax/4 - x³/4

Now to maximize volume we will first differentiate with respect to x and equate it to zero. Hence we get

V' =0

or, A/4 - 3x²/4 = 0

or 3x²/4 = A/4

or, x² = 3

or, x = √3

Now t check whether this gives us the maximum volume we will calculate V"(√3)

V" = -3x/2

V"(√3) = -3√3/2

The correct statements regarding the confidence intervals is given as follows:

The 90% confidence interval for juniors is (.549, .744), and the 90% confidence interval for seniors is (.545, .762). Since the intervals overlap, there is not enough evidence to say there is a difference between regular exercise rates among juniors and seniors.

A confidence interval of proportions has the bounds given by the rule presented as follows:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which the variables used to calculated these bounds are listed as follows:

The confidence level is of 90%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.9}{2} = 0.95[/tex], so the critical value is z = 1.645.

For juniors, the parameters are given as follows:

[tex]n = 65, \pi = \frac{42}{65} = 0.646[/tex]

Then the lower bound of the interval is of:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.646 - 1.645\sqrt{\frac{0.646(0.354)}{65}} = 0.549[/tex]

The upper bound of the interval is of:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.646 + 1.645\sqrt{\frac{0.646(0.354)}{65}} = 0.744[/tex]

For seniors, the parameters are given as follows:

[tex]n = 52, \pi = \frac{34}{52} = 0.654[/tex]

Then the lower bound of the interval is of:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.654 - 1.645\sqrt{\frac{0.654(0.346)}{52}} = 0.545[/tex]

The upper bound of the interval is of:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.654 + 1.645\sqrt{\frac{0.654(0.346)}{52}} = 0.762[/tex]

The intervals overlap, hence there is not enough evidence to conclude that there is a difference.

Answer:

The most appropriate method for solving the first system of equations would be elimination. This can be done by adding the two equations together, which will eliminate one of the variables and leave us with an equation in terms of the remaining variable. We can then solve for the value of this variable and substitute it back into one of the original equations to find the value of the other variable.

For the second system of equations, substitution would be the most appropriate method. This is because one of the equations can be rearranged to solve for the value of one of the variables, which can then be substituted into the other equation. This will eliminate one of the variables and allow us to solve for the value of the remaining variable.

For the third system of equations, graphing would be the most appropriate method. This is because both equations are in the form "y = mx + b," which is the standard form of a linear equation. We can graph both equations on the same coordinate plane and find the point of intersection, which will give us the values of both variables.

The missing angles in the triangle is as follows:

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

∠3 = 55 degrees (vertically opposite angles)

Vertically opposite angles are congruent to each other.

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

Using exterior angle theorem ,

105 = ∠5 + 55

∠5 = 105 - 55

∠5 = 50 degrees

∠4 = 180 - 50 - 55

∠4 = 75 degrees

Therefore, the other triangle is an isosceles triangle. This means the base angles are equal.

Hence,

∠1  = ∠2 = x

2x + 55 = 180

2x = 180 - 55

2x = 125

x = 125 / 2

x = 62.5 degrees.

Hence,

∠1  = ∠2 = 62.5 degrees.
