Chelsea is trying out for her school play. Using subjective probability, she estimates that she has an 80% chance of getting a part and a 25% probability of landing a lead role.

Answers

Answer 1

From the given probabilities, the odds are given as follows:

Getting a part: 4:1.Lead role: 1:3.

What is the missing information?

This problem asks for the odds of both events whose probabilities are given.

What are probabilities and odds?

A probability is given by the number of desired outcomes divided by the number of total outcomes.An odd is given by the number of desired outcomes divided by the number of non-desired outcomes.

Hence, an odd can also be expressed as follows:

Odd = probability/(1 - probability)

Hence the odds are given as follows:

Getting a part: 0.8/(1 - 0.8) = 0.8:0.2 = 4:1.Lead role: 0.25/(1 - 0.25) = 0.25:0.75 = 1:3.

Find the supply and the instantaneous rate of change of the supply with respect to price when the price is 40 dollars.
S(40) = already got (66.677)
S'(40) = ?

Answers

1) The supply when the price is 40 dollars would be; S(40) = 66.677

2)  The instantaneous rate of change of the supply with respect to price when the price is 40 dollars is; 0.0794

How to find the instantaneous rate of change?

We are given the function that represents the number of CD players a retail chain is willing to sell per week at a price of dollars as;

S(p) = 70p/(p + 2)

1) The supply when the price is 40 dollars would be;

S(40) = 70(40)/(40 + 2)

S(40) = 2800/42

S(40) = 66.677

2) The instantaneous rate of change would be gotten by finding the derivative of the supply function to get;

S'(p) = 140/(p + 2)²

Thus;

S'(40) = 140/(40 + 2)²

S'(40) = 0.0794

The equations of the parabolas are given as follows:

a) f(x) = -(x + 6)² - 2.

b) g(x) = (1/32)(x - 6)² + 2

What is the equation of a parabola given it’s vertex?

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

In item a, the vertex is at (-6,-2), hence:

f(x) = a(x + 6)² - 2

When x = -8, f(x) = -6, hence we use it to find a as follows:

-6 = 4a - 2

4a = -4

a = -1.

Hence:

f(x) = -(x + 6)² - 2.

In item b, the vertex is at (6,2), hence:

g(x) = a(x - 6)² + 2

When x = -2, g(x) = 4, hence we use it to find a as follows:

4 = 64a + 2

64a = 2

a = 1/32.

Hence:

g(x) = (1/32)(x - 6)² + 2

A large hotel orders bars of soap to Stocketts rooms once per year if the hotel goes through an average of 750 bars of soap each week how many bars of soap should the hotel order per year

Answers

The hotel should order 39000 bars of soap if the hotel goes through on an average of 750 soaps each week.

In everyday terms, an average is one number chosen to represent a list of numbers; it is often the sum of the numbers divided by the number of numbers in the list (the arithmetic mean).

Average is calculated by dividing the sum of the data by the frequency of the data.

Average=sum ÷ frequency

For example if the average of the data set {1,2,3,5,10}=(1+2+3+5+10)÷5=21÷5=4.2

Now for the given question average is given as 750 bars of soap.

We know that there are 52 weeks in a year.  ∴ frequency=52

Hence sum of all the averages will give the total number of soap ordered by the hotel in a year.

Sum=average × frequency

or, sum=750 × 52

or, sum=39000 bars of soap.

hence the hotel orders 39000 bars of soap in one year.

How to use composition between two functions and find the domain and range of a function

Let a, b be functions, there is a composition when the independent variable of one of the functions is substituted by the other function. For instance,

a ° b (x) = a [b (x)]

The domain of a function is the set of x-values such that the function exists, whereas the range of it is the set of y-values.

If we know that f(x) = 1 / (2 · x + 1) and g(x) = 1 / x, then the composite functions and their domains are:

f ° g (x)

f ° g (x) = f [g (x)]

f ° g (x) = 1 / [2 · (1 / x) + 1]

f ° g (x) = 1 / [(2 + x) / x]

f ° g (x) = x / (2 + x)

The domain of the composite function is all real numbers except - 2 and the range of the composite function is all real numbers except 1.

Scientific notation?

Answers

The scientific notation of the number 140.02943 is 1.4002943 × 10⁻².

What is termed as the scientific notation?Scientific notation is a technique for expressing numbers that are too large or small to be written in basic decimal form. In some contexts, scientific notation is also recognised as standard form, scientific form, or standard index form.The primary reason for the importance of scientific notation is that it enables us to transform very large or extremely small numbers into much manageable sizes. It is much simpler to work with these numbers when they are written in scientific notation. Scientific notation is also crucial because it ensures that calculations involving large numbers remain accurate, as it is often easy to lose track of successfully counting extremely large numbers. For instance, someone will most likely be able to work with 10¹⁰ rather than 10,000,000,000.

The given number is;

140.02943

Shift the 2 decimal to the left of the decimal; because of this, the resultant number will get multiplied by  10⁻².

Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 3 more than 3 times the number of marbles Mark has, how many does each boy have to sell if the total number of marbles is 95?

Answers

Using the concept of linear equation we can conclude that the number of marbles sold by Mark is 23 and the number of marbles sold by Don is 72.

What is a linear equation?

An equation is said to be linear if the highest power of the variable is 1. It is also called as  one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variable is x and A is the coefficient of x, while B is a constant.

Let the number of marbles Mark sells be ‘x’

then, the number of marbles Don sells can be given by ‘3x+3’

Total number of marbles sold=95

We can for equation by adding the number of marbles Mark sells and the number of marbles Don sells  to the total number of marbles sold. The equation formed is

x+3x+3=95

4x+3=95

4x=95-3

4x=92

x=23

The number of marbles Mark sells =23

Number of marbles Don sells=3x+3

Substituting value of ‘x’

Number of marbles Don sells=(3×23)+3

Number of marbles Don sells=69+3

Number of marbles Don sells=72

Thus, the number of marbles sold by Mark is 23.

While, the number of marbles sold by Don is 72.

A certain star is 3.9 x 10^2 light years from the Earth. One light year is about 5.9 x 10^12 miles. How far from the earth​ (in miles) is the​ star?

Answers

Answer: The star is 2 quadrillion( 1 followed by 15 zeroes) and 301 trillion( 1 followed by 12 zeroes) miles away from Earth. To shorten this into scientific notation(the format used to write large numbers) is: 2.301 x 10^15.

Step-by-step explanation: First, find the exact value of the units of measurement, which in  this case is light years. To do so, your best choice would be to separate the equation given for light years. (Note: the line through the middle is just to separate two very similar series of steps.)

1. 5.9 x 10^12 into 5.9 x (10^12)

2. 10^12 = 1,000,000,000,000. 10^12 is the same as adding 11 zeroes since it is multiplying by tens, not 12 zeroes since there is already a zero on the ten. This number is one-trillion(we will shorten this number to 1T).

3. 5.9 x 1T = 5.9 T. Don't get nervous of the big numbers, this is the same as doing 5.9 x 1 and then adding a name afterwards. Now that we have our number, we must remember the question is asking for miles, so keep in mind this large number is the miles.

4. 5.9T --> 5.9 | T Take off the T from 5.9T for now to make this problem a little simpler for this next part.(Note: the | is a separator)

------------------------------------------------------------------------------------------------------------- 5. 3.9 x 10^2 into 3.9 x (10^2)

6. 10^2 = 100. 10^2 is the same as multiplying adding one zero to the ten. This number is one-hundred.

7. 3.9 x 100 = 390. Please remember that this step is to find the number of light years away from the Earth.

8. 390 x 5.9 = 2301. This is the number of lightyears times the number of miles without the zeroes. The next step is to add the zeroes which brings the number into trillions.

9. 2301 | T --> 2301T. Next is to simplify this number, since every zero  after 3 makes the number into a different name, this number is now has 15 zeroes. This number(one-quadrillion) will be shortened to Qu.

10-ish. 2301T = 2.301Qu. This is the name of a number with 15-17 zeroes.

10. 2.301Qu = 2.301 x 10^15. This is just turning the number into scientific notation.

Step-by-step explanation:

A) 6 = 2y - 4

→ 6 = 2(5) - 4

→ 6 = 10 - 4

→ [ 6 = 6 ]

So, the equation is true.

B) 4(b + 5) = 40

→ 4(5 + 5) = 40

→ 4(10) = 40

→ [ 40 = 40 ]

So, the equation is true.

C) (1/5)x + 16 = 17

→ (5/5) + 16 = 17

→ 1 + 16 = 17

→ [ 17 = 17 ]

So, the equation is true.

D) -32 = 2(3p - 6)

→ -32 = 2(15 - 6)

→ -32 = 2 × 9

→ [ -32 ≠ 18 ]

So, the equation is false.
