Answer:

0.0013 = 0.13% probability that no more than four out of fifteen people used an online travel website when they booked their hotel

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they booked the hotel using an online travel website, or they did not. Each person is independent of each other. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Suppose that the probability that a person books a hotel using an online travel website is 0.68.

This means that [tex]p = 0.68[/tex]

Sample of fifteen:

This means that [tex]n = 15[/tex]

What is the probability that no more than four out of fifteen people used an online travel website when they booked their hotel

[tex]P(X \leq 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)[/tex]

So

[tex]P(X = 0) = C_{15,0}.(0.68)^{0}.(0.32)^{15} = 0[/tex]

[tex]P(X = 1) = C_{15,1}.(0.68)^{1}.(0.32)^{14} = 0[/tex]

[tex]P(X = 2) = C_{15,2}.(0.68)^{2}.(0.32)^{13} = 0[/tex]

[tex]P(X = 3) = C_{15,3}.(0.68)^{3}.(0.32)^{12} = 0.0002[/tex]

[tex]P(X = 4) = C_{15,4}.(0.68)^{4}.(0.32)^{11} = 0.0011[/tex]

[tex]P(X \leq 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0 + 0 + 0 + 0.0002 + 0.0011 = 0.0013[/tex]

0.0013 = 0.13% probability that no more than four out of fifteen people used an online travel website when they booked their hotel

Answer:

500 + 100m = 1000 + 50m

Step-by-step explanation:

In order to form an equation we need atleast on variable which in this scenario would be the number of months (m). We can say that we know that sooner or later their savings will equal. Therefore, we can create the following equations for each of their savings progress which are equal to one another...

500 + 100m = 1000 + 50m

This equation if solved would give us the value of 10 for the variable m, meaning that their savings will equal in 10 months. To find out how much each will have in 10 months we can simply grab one half of the equation and substitute 10 for m

500 + 100(10) = x

500 + 1000 = x

1500 = x

Finally, we can see that after 10 months they would both have $1500 saved up.

Answer:

First brand = 18 gallons

Second brand = 12 gallons

Step-by-step explanation:

Let the first brand brand be A and the second brand be B.

Thus, since he wants to obtain 30 gallons of a mixture that contains 30% pure antifreeze, then we have;

A + B = 30 - - - (eq 1)

Also; The first brand is 20% pure antifreeze, and the second brand is 45% pure antifreeze. Thus;

0.2A + 0.45B = (0.3 × 30)

0.2A + 0.45B = 9 - - - (eq 2)

From eq 1, we have; A = 30 - B

Put 30 - B for A in eq 2;

0.2(30 - B) + 0.45B = 9

6 - 0.2B + 0.45B = 9

0.25B = 9 - 6

0.25B = 3

B = 3/0.25

B = 12

Thus, A = 30 - 12 = 18 gallons

Answer:

a = 66⁰

b = 33⁰

Step-by-step explanation:

Given;

∠ABC = 114⁰

To calculate a⁰;

a + 114 = 180⁰ (opposite angles of a quadrilateral are supplementary)

a = 180 - 114

a = 66⁰

To calculate b⁰;

Line AB = Line BC, thus, ∠BAC = ∠BCA

∠BAC = b,      then  ∠BCA = b

b + b + 114 = 180 (sum of angles in a triangle)

2b = 180 - 114

2b = 66

b = 66/2

b = 33⁰

Answer:

The percent of change is -60%.

Step-by-step explanation:

To find the percentage of change, we find the percentage of the final value, considering the initial valuie is 100%, and then we subtract 100% by the percengate found.

In this question:

Initial price of $3.25 per gallon, which is 100% = 1.

Final value of $1.30, which is x. So

$3.25 - 1

$1.30 - x

[tex]3.25x = 1.30[/tex]

[tex]x = \frac{1.30}{3.25}[/tex]

[tex]x = 0.4[/tex]

The initial value of 0.4 = 40% of the initial value.

So the percent of change is a decrease of 100% - 40% = 60%, that is, -60%.

Step-by-step explanation:

Answer:

2.5% of American women have shoe sizes that are greater than 11.47.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 8.47

Standard deviation = 1.5

The normal distribution is symmetric, which means that half the measures are below the mean, and half are above the mean.

What percentage of American women have shoe sizes that are greater than 11.47?

11.47 = 8.47 + 2*1.5

This means that 11.47 is two standard deviations above the mean.

Of those measures below the mean, none are greater than 11.47.

Of those measures above the mean, 95% are between the mean and 11.47, and 5% are above. So

0.5*0.05 = 0.025

2.5% of American women have shoe sizes that are greater than 11.47.

Answer:

For x=2, the expression 4(5x-8) will be 4 more than the expression 2(4-x)

Step-by-step explanation:

Given expressions are;

4(5x-8) and 2(4-x)

For 4 more than the second expression, we will add 4 with second expression.

4(5x-8) = 2(4-x) + 4

20x - 32 = 8 -2x +4

20x + 2x = 12 + 32

22x = 44

Dividing both sides by 22

[tex]\frac{22x}{22}=\frac{44}{22}\\x=2[/tex]

Hence,

For x=2, the expression 4(5x-8) will be 4 more than the expression 2(4-x)

Answer:

m = 17.78.

Step-by-step explanation:

Given the algebraic expression;

2.5m + 10 = 1.6m - 6​

To find the value of m;

First of all, we would collect like terms.

2.5m - 1.6m = -6​ - 10

0.9m = -16

m = -16/0.9

m = 17.78

Answer:

(a) yes

(b) 104% profit

Step-by-step explanation:

250 apples for $22,500 (were they gold?)

Part 1:

50x$120=$6000

Part 2:

200 sold at $1000 per 5 apples=200/5x1000=$40,000

$40,000+$6000=$46,000

A profit of $23,500

23500/22500=1.044 or 104% profit

Fraction Models

Given a number N, to model the process of sharing N into M equal parts we use the division N/M or the fraction

[tex]\frac{N}{M}[/tex]

There are N=5 cakes to be shared between M=6 people, thus the fraction that represents or models the situation is
