Answer:

a

  [tex]P(a | e') =  0.22[/tex]

  [tex]P(b | e') =  0.28[/tex]

  [tex]P(c | e') =  0.33[/tex]

b

  [tex]P(a | e' , d' , b') = 0.57  [/tex]

Step-by-step explanation:

From the question we are told that

   The probabilities are

Supplier  chosen            A                     B                    C            

Probability                P(a) = 0.20       P(b) =  0.25   P(c) =  0.15      

                                       D                      E

                                P(d) =  0.30     P(e) = 0.10

Generally the new probability of companies A being chosen as the sole supplier this year given that supplier E goes out of business is mathematically represented as below according to Bayes theorem

[tex]P(a | e') =  \frac{P (a \  and \  e')}{P(e')}[/tex]

      [tex]P(a | e') =  \frac{P (a)}{P(e')}[/tex]

     [tex]P(a | e') =  \frac{P (a)}{1- P(e)}[/tex]

=>   [tex]P(a | e') =  \frac{ 0.20}{1- 0.10}[/tex]

=>   [tex]P(a | e') =  0.22[/tex]

Generally the new probability of companies B  being chosen as the sole supplier this year given that supplier E goes out of business is mathematically represented as below according to Bayes theorem

[tex]P(b | e') =  \frac{P (b \  and \  e')}{P(e')}[/tex]

      [tex]P(b | e') =  \frac{P (b)}{P(e')}[/tex]

     [tex]P(b | e') =  \frac{P (b)}{1- P(e)}[/tex]

=>   [tex]P(b | e') =  \frac{ 0.25}{1- 0.10}[/tex]

=>   [tex]P(b | e') =  0.28[/tex]

Generally the new probability of companies C  being chosen as the sole supplier this year given that supplier E goes out of business is mathematically represented as below according to Bayes theorem

[tex]P(c | e') =  \frac{P (c \  and \  e')}{P(e')}[/tex]

      [tex]P(c | e') =  \frac{P (c)}{P(e')}[/tex]

     [tex]P(c | e') =  \frac{P (c)}{1- P(e)}[/tex]

=>   [tex]P(c | e') =  \frac{ 0.15}{1- 0.10}[/tex]

=>   [tex]P(c | e') =  0.17[/tex]

Generally the new probability of companies D  being chosen as the sole supplier this year given that supplier E goes out of business is mathematically represented as below according to Bayes theorem

[tex]P(d | e') =  \frac{P (d \  and \  e')}{P(e')}[/tex]

      [tex]P(d | e') =  \frac{P (d)}{P(e')}[/tex]

     [tex]P(d | e') =  \frac{P (d)}{1- P(e)}[/tex]

=>   [tex]P(d | e') =  \frac{ 0.30}{1- 0.10}[/tex]

=>   [tex]P(c | e') =  0.33[/tex]

Generally the probability that  B, D , E  are not chosen this year is mathematically represented as

      [tex]P(N) =  1 - [P(e) +P(b) + P(d) ][/tex]

=>       [tex]P(N) =  1 - [0.10 +0.25  +0.30 ][/tex]

=>       [tex]P(N) =  0.35[/tex]

Generally the probability that A is chosen given that E , D , B  are rejected this year is mathematically represented  as

      [tex]P(a | e' , d' , b') =  \frac{P(a)}{P(N)}[/tex]

=>     [tex]P(a | e' , d' , b') =  \frac{0.20 }{0.35 }[/tex]    

=>     [tex]P(a | e' , d' , b') = 0.57  [/tex]

Answer:

[tex]y = \frac{1}{4}x +\frac{7}{4}[/tex]

Step-by-step explanation:

Given

[tex]f(-3) = 1[/tex]

[tex]f(13) = 5[/tex]

Required

Determine the linear function

A function is of the form:

[tex]y = f(x)[/tex]

Writing the given parameters in (x,y) format, we have:

[tex]f(-3) = 1[/tex] implies (-3,1)

[tex]f(13) = 5[/tex] implies (13,5)

So, the x and y values are:

(-3,1) and (13,5)

i.e.

[tex](x_1,y_1) = (-3,1)[/tex]

[tex](x_2,y_2) = (13,5)[/tex]

First, we need to determine the slope using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{5 - 1}{13 - -(3)}[/tex]

[tex]m = \frac{4}{13 +3}[/tex]

[tex]m = \frac{4}{16}[/tex]

[tex]m = \frac{1}{4}[/tex]

The equation is calculated as thus:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex](x_1,y_1) = (-3,1)[/tex]

[tex]m = \frac{1}{4}[/tex]

[tex]y - 1 = \frac{1}{4}(x - (-3))[/tex]

[tex]y - 1 = \frac{1}{4}(x +3)[/tex]

[tex]y = \frac{1}{4}(x +3) + 1[/tex]

[tex]y = \frac{1}{4}x +\frac{3}{4} + 1[/tex]

[tex]y = \frac{1}{4}x +\frac{3+4}{4}[/tex]

[tex]y = \frac{1}{4}x +\frac{7}{4}[/tex]

Answer:

The age of pluto is:

5,560,000,000 years old = 5.56 × 10⁹ years old

x = 5.56

y = power of 9

Step-by-step explanation:

Pluto is 5,560,000,000 years old. Estimate the age of Pluto by writing it in the form of x×10y years, where x and y are single-digit numbers.

We write this in standard form or scientific notation.

5,560,000,000 years old = 5.56 × 10⁹ years old

x = 5.56

y = power of 9

The Least Common Denominator of the fractions 5/8, 1/2, and 5/6 is 24.

The smallest number that can serve as a common denominator for a group of fractions is known as the least common denominator (LCD), also known as the lowest common denominator. The "smallest non-zero common number," a multiple of both numbers, is the least common multiple of two numbers.

Here, the given fractions are 5/8, 1/2, and 5/6.

So, we have to find the least common multiple of 8, 2, and 6 [Since they are the denominators of our given fractions].

8 = 2*2*2

2 = 2*1

6 = 2*3

So LCM of 8, 2, and 6 is 2*2*2*3 = 24

Therefore the Least Common Denominator of the fractions 5/8, 1/2, and 5/6 is 24.

13. Discount price= 12.87 Sale price= 26.13

14. 40.80

15. 12,750

I'm not 100% on #15 but the rest are good.

Step-by-step explanation: When you multiply the percent by the other number that gives you the difference. So then get the original number and either add or subtract the difference from the original number to get your answer. Add if increase Subtract if decrease.

So 7-11 you just have to multiply the percent by the other number.

7. 25*300% or 25*3 = 75  25 + 75 = 100

8. 56*.75 = 42  56-42= 14

9. 12000*.05 = 600 (since it is an increase add 600 to 12000) = 12600

10. 710*.10= 71 (71 is the difference so do this) 710-71= 639

11. 160*.20 = 32 (decrease) 160-32= 128

12. 380*.05=19 (increase) 380+19 = 399

13. 39*.33= 12.87 (decrease)

Discount price = 12.87

Sale price= 39-12.87= 26.13

14. 48*.15 = 7.20 (decrease) 48-7.20= 40.80

15. 3,000*3.25 = 9750 (increase) 9750 + 3000= 12,750

Step-by-step explanation:

5x-15y=1

-5x -15y= 1 -5x     change the signs on both sides of the equation

     15y = -1 +5x      divide both sides by 15

         y = -1/15 + 1/3 x    Reorder the terms

         y = 3x-15

              :)

All options are wrong here.

Given equation is  [tex]y=3x-15[/tex].

the equation given here is in form of [tex]y=mx+c[/tex] . The general equation of any straight line where m is the gradient of the line (how steep the line is) and c is the y -intercept (the point in which the line crosses the y -axis) .

We have to write [tex]y=3x-15 \\[/tex] in standard form.

The standard form for linear equations in two variables is Ax+By=C.

Now we convert [tex]y=3x-15[/tex] in standard form.

Here [tex]y=3x-15\\[/tex]

[tex]y-3x=-15\\\\-y+3x=15[/tex]

[tex]3x-y=15[/tex]

But no options match with the above standard form of equation.

There is sufficient evidence that indicate that there is a significant difference between the two treatments

Step-by-step explanation:

From the question we are told that  

    The sample size is  n =  12

    The first  mean is  [tex]M_1  =  55[/tex]

    The variance is  [tex]s^2_1 =  8[/tex]

    The second mean is  [tex]M_2  =  52[/tex]

     The second variance is [tex]s^2_2 =  4[/tex]

Let the level of significance be  [tex]\alpha  =  0.05[/tex]

The null hypothesis is  [tex]H_o  :  M_1 = M_2[/tex]

The alternative hypothesis is [tex]H_a  :  M_1 \ne M_2[/tex]

  Generally the test statistics is mathematically

     [tex]t = \frac{M_1 - M_2 }{ \sqrt{\frac{s_1^2}{n_1} +\frac{s_2^2}{n_2}} }[/tex]

=>   [tex]t = \frac{55 - 52 }{ \sqrt{\frac{8}{12} +\frac{4}{12 }} }[/tex]

Numerical variables acn be classed as either being discrete or continuous based on whether the values in the data set are finite and countable or not.

Discrete variables are characterized by possessing a finite number of possible values which are countable and usually do not involve decimal numbers in between successive whole numbers.

On the other hand continuous variables are non finite and usually contains a lot of points in between possible whole numbers such as in the scenario above, the race time for the students take up any number within minutes, seconds and milliseconds.

А. The solution to this system is nonviable because it results in a fractional number of tickets.

Step-by-step explanation:

Let x represent the number of adult tickets, y represent the number of child ticket and z represent the number of senior ticket.

Since the number of purchased ticket is 17, hence:

x + y + z = 17         (1)

The total cost of tickets is $141.50, hence:

10x + 7y + 8.5z = 141.5       (2)

they are purchasing 2 more senior tickets than adult tickets, therefore:

x = z + 2        (3)

Solving equation 1 2 and 3 simultaneously gives:

x =17/3, y = 23/3, z = 11/3

Therefore the solution to this system is nonviable because it results in a fractional number of tickets.
