The longer trail is outlook trail.

Mixed fractions are type of fractions which consist of a whole number part and a fractional part.

Mixed fractions are of the form a b/c where a is the whole number part and b/c is the fractional part.

The lengths of these trails are given in the mixed number form.

First, converting it into improper fraction,

Length of lake trail = 4 3/5 mile = (4 × 5 + 3) / 5 = 23/5 miles

Length of outlook trail = 5 5/6 mile = (5 × 6 + 5) / 6 = 35/6 miles

Length of pinewood trail = 1 3/10 mile = (1 × 10 + 3) / 10 = 13/10 miles

35/6 > 13/10

Outlook trail is longer.

Hence the outlook trail is the longer trail.

The mixture used 13.125 pounds of peanuts and 21.875 pounds of cashews to produce 35 pounds of the mixture.

Let x = the number of pounds of peanuts used in the mixture

Let y = the number of pounds of cashews used in the mixture

We can set up the following equation to solve for x and y:

2.25x + 3.25y = 2.65(x + y)

We can rearrange the equation to solve for x:

2.25x + 3.25y - 2.65x - 2.65y = 0

0.6x - 0.6y = 0

x = 0.6y

Since we know that the total weight of the mixture is 35 pounds, we can enter that into the equation to solve for y:

0.6y + y = 35

1.6y = 35

y = 21.875 pounds of cashews

x = 0.6(21.875) = 13.125 pounds of peanuts

Therefore, the mixture used 13.125 pounds of peanuts and 21.875 pounds of cashews to produce 35 pounds of the mixture.

The point of intersection is (1.82, 1.45).

The equations of the two lines are:

y = 0.8x and y = -2.5x + 6.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of a line is given by:

y = mx + c

From the graph,

Take two coordinates from each line.

One line:

(0, 0) and (2.5, 2)

m = (2 - 0) / (2.5 - 0)

m = 2/2.5

m = 0.8

(0, 0) = (x, y)

0 = 0.8 x 0 + c

c = 0

So,

y = 0.8x

Another line:

(2, 1) and (1, 3.5)

m = (3.5 - 1) / (1 - 2)

m = 2.5 / -1

m = -2.5

(2, 1) = (x, y)

1 = -2.5 x 2 + c

1 = -5 + c

c = 1 + 5

c = 6

So,

y = -2.5x + 6

Now,

The point of intersection is (1.82, 1.45).

0.8x = -2.5x + 6

0.8x + 2.5x = 6

3.3x = 6

x = 6/3.3

x = 1.82

And,

y = 0.8x

y = 0.8 x 1.82

y = 1.45

Thus,

(1.82, 1.45) is the point of the intersection.

y = 0.8x and y = -2.5x + 6 are the equation of the line.

If the length of the tube is 84.5cm and the diameter of the tube is 2.40 cm, then area of poster is 636.7 cm² ~ 637 cm²

Given that ;

Length of the cylinder = 84.5 cm

Diameter of the cylinder = 2.40 cm

Then the radius is 1.20 cm

When the poster is uncurled it is in rectangle shape so, length of the poster is 84.5cm.

When poster is curled in cylinder, circumference of circle is breadth of poster = 2πr = 2(22/7)1.2 = 7.53 cm

So the area of poster is length × breadth

Area = 84.5cm × 7.53cm

According to the z table, there is a 0.3814 percent chance that a standard normal random variable will fall between 0.3 and 3.2.

The probability is calculated by dividing the total number of outcomes by the total number of potential events.

Odds and probability are two different concepts.

Calculating odds involves dividing the probability of an event by the probability that it won't happen.

Probability is the study of random events in mathematics, and it can be classified into four main categories: axiomatic, classical, empirical, and subjective.

So, we must determine the likelihood that a standard normal random variable will occur with a probability between 0.3 and 3.2.

First, a standard normal random variable with a mean and standard deviation is introduced.

We must determine the likelihood that a standard normal random variable will fall within the range of 0.3 and 3.2.

The likelihood therefore should be:

P(0.3<z<3.2)=P(z<3.2)−P(z<0.3)

Using z's typical value:

P(0.3<z<3.2)=0.9993−0.6179

Simplify as follows:

P(0.3<z<3.2)=0.3814

Therefore, according to the z table, there is a 0.3814 percent chance that a standard normal random variable will fall between 0.3 and 3.2.

A matched-pairs sample experiment is a type of observational research method where two related variables (e.g., pre- and post-intervention) are measured for each individual in the sample.

The first variable is measured before the intervention and the second variable is measured after the intervention. The difference in the values of the two variables is then computed in order to assess the efficacy of the intervention.

The formula used to calculate the difference between the two values is:

Difference = Post Variable - Pre Variable

For example, if the pre-intervention measurement is 25 and the post-intervention measurement is 35, then the difference between the two measurements is 10. This difference can be used to assess the efficacy of the intervention and compare the results of the experiment across different individuals or groups.

Kala used 55 pounds of type A coffee and 79 pounds of type B coffee in 134 pounds of the blend for a total cost of $717.90.

Let number of pounds in coffee type A be taken as A

Let number of pounds in coffee type B be taken as B

The total number of pounds used in the blend = 134 pounds.

Therefore, A + B = 134

A = 134 – B …….. (i)

1 pound of coffee type A costs = $4.65

Therefore, A pounds of type A coffee will cost = $4.65A

1 pound of coffee type B costs = $5.85

Therefore, B pounds of type B coffee will cost = $5.85B

Total cost of both blends = $717.90

Therefore, 4.65A + 5.85B = 717.90…….(ii)

Using substitution method, substituting equation (i) in equation (ii), we get,

4.65 * (134 – B) + 5.85B = 717.90

623.1 – 4.65B + 5.85B = 717.90

623.1 + 1.2B = 717.90

Step-by-step explanation:

General equation of a parabola isy =  ax² + bx + c

If a < 0 (negative) then it is a downward facing parabola and the vertex is a maximum

If a > 0 then  it is an upward facing parabola and the vertex is a minimum

Given parabola is
y =  -3x² - 18x -24

and comparing to the general equation we get a = -3, b = -18 and c = -24

So the vertex is a maximum

The x-coordinate of the vertex is given by
[tex]x_v =- \dfrac{b}{2a}\\\\[/tex]

Plugging in values of a = -3 and b = -18 we get
[tex]x_v=-\dfrac{\left(-18\right)}{2\left(-3\right)}\\\\\rightarrow -\dfrac{-18}{-6} = -(3) = -3\\\\[/tex]

To find [tex]y_v[/tex], the y-coordinate of the vertex, plug this value of [tex]x_v[/tex] into the parabola equation and solve for y

[tex]y_v=-3\left(-3\right)^2-18\left(-3\right)-24\\\\y_v = -3(9) +54 -24\\\\y_v = -27 + 54 - 24\\\\y_v = 3\\\\[/tex]

350 adult tickets were sold and 350 child tickets were sold.

Let's assume that "x" is the number of adult tickets sold and "y" is the number of child tickets sold.

We know that:

x + y = 700 (the total number of tickets sold)

7.5x + 5y = 4500 (the total revenue)

We can use the first equation to solve for one of the variables in terms of the other.

For example:

y = 700 - x

Substituting this into the second equation:

7.5x + 5(700 - x) = 4500

7.5x + 3500 - 5x = 4500

2.5x = -900

x = -360

Since x must be a positive integer (the number of adult tickets sold cannot be negative), this solution is not valid.

However, we can see that the equation does have a solution by trying a larger value for x:

x = 700

y = 0

This gives us:

7.5 * 700 + 5 * 0 = 4500

5250 = 4500

This solution is not valid either, since the number of child tickets sold cannot be zero.

By repeating this process, we can find that the solution is x = 350 and y = 350.
