Based on the information, we can infer that Cliff's experiment will have similar numbers regarding the frequency of each letter while Devon will have a higher frequency of the letters A, E, U than the letters O and I.

To interpret the information from the experiments we must take into account the experiments that each one carried out. In the first case, Cliff always had the same probability of drawing a vowel from the bag, that is, 1/5.

However, in Devon's case, the arrow was less likely to point to the letters O and I because they occupy a smaller area on the spinner.

Based on the above, Cliff's frequency plot is more likely to have the values in a "similar" range for all letters, while Devon is going to have a majority on letters A, E, U.

The exponential decay model that represents the forest cover in the world t years after 1990 is:

We can use the exponential decay model to represent the decrease in the world forest cover over time:

y = a e^(kt)

where

y is the forest cover in 10^6 hectares,

t is the time ,

a is the initial forest cover,

k is the decay rate.

Solving for a and k:

where a = 4168 million hectares  (given)

When t = 20  the forest cover was 4033 million hectares.

y = a e^(kt)

y = 4033 = 4168 e^(k*20)

4033/4168 = e^(k*20)

Taking the natural logarithm of both sides:

ln(4033/4168) = k*20

Solving for k, results to

k = ln (4033 / 4168) / 20

The area of the triangle formed by the x-axis, the y-axis and the line y=−x+12 is found to be 72 square units.

We have to find the vertices of triangle bounded by the x and y-axis and the line y = -x + 12 to solve the problem. The x-intercept of the line y = -x + 12 occurs when y = 0, so we have,

0 = -x + 12

x = 12

So, we get, (0,0), (12,0), (0,12). Using the formula, A = 1/2 x base x height. In this case, the base and height of the triangle are both 12, so we have,

The answer of the given question based on distance is , the two trains will meet 60 km from Station X.

Speed is the  measure of how fast object is moving. It is the distance an object travels per unit of time. The SI unit for speed is meters per second (m/s), but it can also be expressed in other units, like kilometers per hour (km/h), miles per hour (mph), feet per second (ft/s), etc.

Let's first consider the relative speed between the two trains. Since they are moving towards the each other, we can add their speeds:

Relative speed =Speed of train A+Speed of train B

= 60 km/hr + 30 km/hr

= 90 km/hr

Now, we can use the formula:

distance = speed × time

Let's assume that the two trains meet at a distance of x km from Station X. Then, the distance that train A travels before meeting train B is (180 - x) km.

Using the formula for train A:

distance = speed × time

(180 - x) = 60t

where t is the time taken for the two trains to meet.

Using the formula for train B:

distance = speed × time

x = 30t

Now, we can substitute the value of x from the second equation into the first equation:

(180 - 30t) = 60t

Simplifying this equation, we get:

180 = 90t

t = 2 hours

Therefore, the two trains will meet after 2 hours of travel.

To find the distance from Station X where they meet, we can substitute t = 2 into either of the two equations for x:

x = 30t = 30 × 2 = 60 km

Therefore, the two trains will meet 60 km from Station X.

Answer:

The formula for continuous compounding is given as:

A = Pe^(rt)

where A is the final amount, P is the initial amount, r is the annual interest rate (as a decimal), t is the time in years, and e is the mathematical constant approximately equal to 2.71828.

To find the time for an investment to double, we can set A/P = 2 and solve for t:

2 = e^(rt)

Taking the natural logarithm of both sides, we get:

ln(2) = rt

Solving for t, we get:

t = ln(2)/r

Substituting r = 0.0575 (since 5.75% = 0.0575 as a decimal), we get:

t = ln(2)/0.0575 ≈ 12.06 years

Therefore, at an annual interest rate of 5.75% compounded continuously, it takes approximately 12.06 years for an investment to double.

Answer:

b= 23.4,. γ = 70°, c= 28.9

Step-by-step explanation:

To solve the triangle with given α = 65°, β = 45°, and a = 30, we can use the law of sines:

b/sin(β) = a/sin(α)

b/sin(45°) = 30/sin(65°)

b ≈ 23.4

Then, to find angle γ, we can use the fact that the sum of angles in a triangle is 180°:

γ = 180° - α - β

γ ≈ 70°

To find side c, we can again use the law of sines:

c/sin(γ) = a/sin(α)

c/sin(70°) = 30/sin(65°)

c ≈ 28.9

Therefore, the solution is b = 23.4, γ = 70°, and c = 28.9.

Question 3, part (a)

The tangent line is perpendicular to the radius at the point of tangency.

If AB was tangent to circle C, then radius AC would be perpendicular to segment AB. Meaning that angle BAC should be 90 degrees, and it should lead to triangle ABC being a right triangle.

Use the pythagorean theorem converse to see if we have a right triangle or not.

a^2 + b^2 = c^2

5^2 + 11^2 = 13^2

25 + 121 = 169

146 = 169

The last equation is false so the first equation is false when a = 5, b = 11, c = 13. Triangle ABC is not a right triangle. We've proven angle BAC isn't 90 degrees.

====================================================

Question 3, part (b)

We'll use the same template of steps as done back in part (a).

This time we have:

The order of 'a' and b doesn't matter. The c is always the longest side.

a^2 + b^2 = c^2

6^2 + 8^2 = 10^2

36 + 64 = 100

100 = 100

The last result is true so the first equation is true for the a,b,c values mentioned. Notice the equation would also be true if a = 8, b = 6, c = 10.

Therefore, triangle ABC is a right triangle where the 90 degree angle is at point A.

====================================================

Answer:

(a) No

(b) Yes

Step-by-step explanation:

The tangent of a circle is always perpendicular to the radius.

Since AC is the radius of circle C, if AB is a tangent to circle C, then m∠BAC = 90°.

As we have been given the measures of all three sides of both triangles, we can use Pythagoras Theorem to determine if the measure of angle BAC in both triangles is a right angle.

Pythagoras Theorem explains the relationship between the three sides of a right triangle. The square of the hypotenuse (longest side) is equal to the sum of the squares of the legs of a right triangle:

[tex]\boxed{a^2+b^2=c^2}[/tex]

where:

The legs of this triangle are AC and AB. The hypotenuse is BC.

Substitute the measures of the sides into the Pythagoras Theorem formula:

[tex]\implies AC^2+AB^2=BC^2[/tex]

[tex]\implies 5^2+11^2=13^2[/tex]

[tex]\implies25+121=169[/tex]

[tex]\implies146=169[/tex]

As 146 does not equal 169, this proves that the triangle is not a right triangle. Therefore AB is not tangent to circle C.

The legs of this triangle are AC and AB. The hypotenuse is BC.

Substitute the measures of the sides into the Pythagoras Theorem formula:

[tex]\implies AC^2+AB^2=BC^2[/tex]

[tex]\implies 6^2+8^2=10^2[/tex]

[tex]\implies 36+64=100[/tex]

[tex]\implies100=100[/tex]

As both sides of the equation are the same, this proves that the triangle is a right triangle and m∠BAC = 90°. Therefore AB is tangent to circle C.

The number of people who attended the movie are as follows;

Number of children = 162 children.

Number of adults = 81 adults.

Number of students = 50 students.

In order to determine the number of children, students, and adults that attended, we would assign a variable c to the the total number of children who attended the movie.

Since there are half as many adults as there are children, we have the following:

Number of adults = c/2.

Similarly, the number of students who attended the movie can be calculated as follows;

Number of students = 293 - (c + c/2)

Number of students = 293 - 3c/2

Since the total ticket sales were $2132, a linear equation to model it is given by:

2132 = 5c + 7(293 - 3c/2) + 12(c/2)

2132 = 5c + 2,051 - 21c/2 + 12c/2

2132 - 2051 = 5c - 9c/2

81 = c/2

c = 162 children.

Students = 293 - 3c/2

Students = 293 - 3(162)/2

Students = 293 - 243

Evaluate

m(0) = 160/15

So, we have

m(0) = 32/3

Set m(x) = 0 to calculate the x intercepts

So, we have

[4(x - 5)(x + 8)]/[x^2 - 2x - 15] = 0
