Answers

Answer:

275, 375, 475

Step-by-step explanation:

First, find the slope using the two pairs of values given.

Number of days = x

Total number of trophies = y

Using (3, 80) and (7, 180),

Slope = ∆y/∆x = (180 - 80)/(7 - 3) = 100/4 = 25

Slope/unit rate = 25 trophies per day

Multiply 25 by each given number of days to get each corresponding total number of trophies won.

Thus:

✔️Number of days = 11

Total number of trophies won = 11*25 = 275

✔️Number of days = 15

Total number of trophies won = 15*25 = 375

✔️Number of days = 19

Total number of trophies won = 19*25 = 475

Answer:

Denominator stays the same (16)

11 / 16

Answer:

4.5/16+6/16=4.5+6/16

=10.5/16

Step-by-step explanation:

Here you can see denominator in both the side are same and operation sign between them is plus, therefore you can take denominator as is it.

Then add numerator and divide by denominator which is 16. Answer is 10.5/16 since you have to simplify only.

Fischer and Spassky play a chess match in which the first player to win a game wins the match. After 10 successive draws, the match is declared drawn. Each game is won by Fischer with probability 0.4, is won by Spassky with probability 0.3, and is a draw with the probability 0.3 independent of previous games.
(a) What is the probability that Fischer wins the match?
(b) What is the PMF of the duration of the match?

Answers

Answer:

a)

the probability that Fischer wins the match is 0.5714

b)

p( D = d ) = { [tex]( 0.3 )^{d-1[/tex] [tex](0.7)[/tex],  d = 1, 2, 3, ........

                                 [tex]0[/tex]                     otherwise

Step-by-step explanation:

Given that;

probability that Fischer wins the match, p = 4

probability that Spassky wins the match, q = 0.3

Match drawn, 1 - p - q = 1 - 0.4 - 0.3 = 0.7

(a) What is the probability that Fischer wins the match?

P( Fischer wins) = p/( p+q)

we substitute

P( Fischer wins) = 0.4 / ( 0.4 + 0.3)

P( Fischer wins) = 0.4 / 0.7

P( Fischer wins) = 0.5714

Therefore, the probability that Fischer wins the match is 0.5714

b) What is the PMF of the duration of the match?

let D represent the duration of the match

since the duration D of the match is a geometric random variable with parameter p + q,

the PMF will be;

p( D = d ) = [tex]( 1 - p - q )^{d-1[/tex] ( p + q )

= [tex]( 1 - 0.4 - 0.3 )^{d-1[/tex] ( 0.4 + 0.3 )

p( D = d ) = [tex]( 0.3 )^{d-1[/tex] ( 0.7)

that is, p( D = d ) = { [tex]( 0.3 )^{d-1[/tex] [tex](0.7)[/tex],  d = 1, 2, 3, ........

                                 [tex]0[/tex]                     otherwise

The estimated proportion of all shoppers who were happy with their experience that day and said yes is 0.667.

What is random sample?

Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.

A store owner asks each person to write "Yes" or "No" on a slip of paper as they leave, secretly writing down whether they were happy with their experience.

At the end of the day, the owner selects 12 slips at random and looks at them. These were the results:

yes, yes, yes, no, yes, no, yes, yes, no, yes, no, yes=12yes=8

To estimate the proportion is the following formula:

[tex]p'=\dfrac{x}{n}[/tex]

Here, x is the number of success and n is the sample size. Here, the sample size is 12 and number of success (yes) is 8. Thus, the estimated proportion is:

[tex]p'=\dfrac{8}{12}\\p'=0.667[/tex]


Thus, the estimated proportion of all shoppers who were happy with their experience that day and said yes is 0.667.

A camp director developed the function m(c) = 12c + 80 to model the total cost of taking c campers on a field trip to the movies.


In the camp director’s function, the number of campers is the _______ variable and the total cost of the trip _________


1. ( independent, dependent )

2. ( changes by a constant factor per camper, Changes by a constant amount per camper )

.

Answers

Answer:

(a) Independent variable

(b) The constant factor is 12

Step-by-step explanation:

Given

[tex]m(c) = 12c + 80[/tex]

c = campers

m = total cost

Solving (a) What type of variable is the number of campers (c)

The total cost (m) is dependent on the number of campers (c) for its own value.

In other words, if c changes from 5 to say 7, the value of m will also change.

This implies that the number of campers is an Independent variable

Solving (b): Constant factor

This in other words means, rate of change (or slope)

A linear function is:

[tex]y = ax + b[/tex]

Where a represents the slope

By comparison with: [tex]m(c) = 12c + 80[/tex]

Hence, the constant factor is 12

Answer:

dependent, changes by a constant factor per camper.
