(b) a telemarketing supervisor tells a new worker that the odds of making a sale on a single call are 6 to 13. what is the probability of a successful call? (round your answer to two decimal places.)
Probability of a successful call 0.3157 = 31.57%
Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will learn the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.
A probability is the number of desired outcomes divided by the number of total outcomes.
The odds of making a sale on a single call are 6 to 13.
This means that in 6+13 = 19 calls, 6 are successful.
What is the probability of a successful call?
p = 6/19 =
0.3157 = 31.57% probability of a successful call.

How much will $10,000 deposited in an account earning 2.5% interest compounded annually be worth in 20 years?
Answer:
Step-by-step explanation:
The formula to calculate the future value of an investment with compounded interest is:
Future value = Principal * (1 + rate/compoundings per year)^(number of years * compoundings per year)
In this case, the principal is $10,000, the interest rate is 2.5%, compounded annually, and the number of years is 20. So, the future value can be calculated as follows:
Future value = $10,000 * (1 + 2.5%/1)^(20 * 1)
Future value = $10,000 * (1.025)^20
Future value = $10,000 * 1.62897526
Future value = $16,289.75
Therefore, $10,000 deposited in an account earning 2.5% interest compounded annually would be worth $16,289.75 in 20 years.

In the previous problem, how does the angle of depression from the top of the taller building relate to the angle of elevation from the top of the shorter building? a. they are congruentb. they are complementaryc. they are supplementaryd. they are alternate interior anglese. they are alternate exterior anglesf. they are corresponding angles
The angle of depression from the top of the taller building and the angle of elevation from the top of the shorter building are alternate interior angles.
Alternate interior angles are the angles formed when a transversal intersects two coplanar lines. They lie on the inner side of the parallel lines but on the opposite sides of the transversal. The transversal crosses through the two lines which are Coplanar at separate points.
The angles of elevation and depression are formed by the line of sight and the horizontal line. When the line of vision is above the horizontal line, the angle is of elevation, and if the line of sight is below the horizontal, the angle is of depression.
If the angle of depression of the taller building is 15° the angle of elevation of the shorter building is 15° too.

Answer: The value of the sum of x and y is (a) 144.
Step-by-step explanation:
Given, The sequence is a Geometric Sequence.
Initially,
=> 4x3 , x , y , 324, 324x3
=> 4x3, x, y, 4x3x3x3x3, 4x3x3x3x3x3
From above,
We can deduce that,
=> x = 4 x 3 x 3
=> x = 36
Also,
=> y = 4 x 3 x 3 x 3
=> y = 108
The values of x and y are 36 and 108
Now, We can evaluate the sum of x and y,
=> x + y = 36 + 108
=> x + y = 144
Therefore, The sum of x and y is 144. Hence, option (a) is correct.

2. Matt measures the angle of elevation of the peak of a mountain as 35º. Susie, who is 1200
feet closer on a straight level path, measures the angle of elevation as 42º. How high is the
mountain?
The height of the mountain using the angle of elevation is 3858.85 units.
What are trigonometric functions?The three basic categories of trigonometric functions are sine, cosine, and tangent. And from the basic functions, one can deduce the three cotangent, secant, and cosecant functions. In contrast to the fundamental trigonometric functions, the other three functions are essentially employed more frequently.
Let the distance between the mountain and Matt = x.
Then the distance of Susie will be:
S = x - 1200
Matt measure the angle of elevation as 35 degrees.
Using the trigonometric function we have:
tan (35) = h / x
x = h/ 0.7.......(1)
For Susie:
tan(42) = h / x - 1200
0.9(x - 1200) = h
0.9x - 1080.48 = h .........(2)
Substitute the value of x in equation 2:
0.9 ( h/ 0.7) - 1080.48 = h
1.28h - 1080.48 = h
1.28h - h = 1080.48
0.28h = 1080.48
h = 3858.85
Hence, the height of the mountain using the angle of elevation is 3858.85 units.

Calculate the value of , assuming 4 is in radians and that the sin function available in python accepts radians. Store the result in a variable sin4
By using Python to calculate the value of sin4 is a simple process that involves understanding the concept of radians and using the sine function available in Python's math module.
A radian is a unit of measurement for angles. It is defined as the angle formed when the arc length of a circle is equal to the radius of that circle. This means that an angle of 1 radian is equal to the angle formed by an arc length of 1 radius on a circle.
The sine function, denoted as sin(x), is a mathematical function that takes an angle x as input and returns the ratio of the opposite side to the hypotenuse in a right-angled triangle with an angle x.
Now, we can proceed to calculate the value of sin4 using Python. In Python, the sine function is available in the math module, so we will need to import this module at the beginning of our code. We will then use the sin() function to calculate the sine of 4 radians as follows:
import math
sin4 = math.sin(4)
Here, we are calling the sin() function and passing it the value of 4 as an argument. Since the sine function in Python accepts radians, we do not need to convert 4 to degrees.
Finally, we store the result of this calculation in a variable called sin4. This variable will now hold the value of the sine of 4 radians, which we can use in our program as needed.

The sum of the measures of angles A, D, and F is:

How to find the sum of the 3 angles?First, we know that the sum of the interior angles of any triangle is always equal to 180°, then we can write:
B + C + E = 180°
We also can see that:
A + B = 180°
C + D = 180°
E + F = 180°
Then we can rewrite:
E = 180° - F
C = 180° - D
B = 180° - A
And replace that on the equation above:
B + C + E = 180°
( 180° - F) + (180° - D) + (180° - A) = 180°
Moving the variables to the right side we will get:
3*180° = 180° + A + D + F
3*180° - 180° = A + D + F
360° = A + D + F

The Grade 8 learners decided to start living more healthily.They will either jog or cycle.there are 125 Grade 8 learners and they jog and cycle in the ratio 3:2.calculate how many learners participate in each sport
Answer:
We can start by finding the total number of learners who participate in jogging and cycling by multiplying the ratio by the total number of learners. Let's say x is the number of learners who jog. Then, the number of learners who cycle is 2x.
The total number of learners who jog and cycle is 125, so:
x + 2x = 125
3x = 125
x = 125 / 3
x = 41.67
Since x represents the number of learners who jog, there are 41.67 learners who jog. Since the number of learners who cycle is 2x, there are 2 * 41.67 = 83.33 learners who cycle.
Since these are whole numbers of learners, we round up to the nearest whole number to get 42 joggers and 83 cyclists.
The number of students participating in each of the sports will be 75 for jogging and 50 for cycling.
Solution:
Let's assume that the number of students who participated in jogging will be 3x and those in cycling will be 2x
Given,
3x + 2x = 125
5x = 125
So, x = 25
Therefore, the number of students in jogging will be 3*25 = 75 and in cycling will be 2*25 = 50
