Answer:

For each game, the player should be expected to lose $0.0263.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of each outcome:

1/38 probability of winning, that is, 1/38 probability of receiving $36.

37/38 probability of losing, that is, 37/38 probability of losing $1.

On average, how much money should a player expect to win or lose if they play this game repeatedly?

For each game:

[tex]E(X) = \frac{1}{38}*36 - \frac{37}{38}*1 = \frac{36 - 37}{38} = -\frac{1}{38} = -0.0263[/tex]

For each game, the player should be expected to lose $0.0263.

Simply plug 3 into the equation.

[tex]f(3) = 3(3)^2+2(3) = 3(9) + 6 = 27 + 6 = 33\\\\\\f(3) = 33[/tex]

Answer:

Step-by-step explanation:

Plugin x = 3 in the function

f(x) = 3x² + 2x

f(3) = 3*(3)² + 2*3               {3² = 3*3 = 9}

     = 3*9 + 6

     = 27 + 6

f(3) = 33

Answer:

10 hours or diez horas

Step-by-step explanation:

El total de horas entre las 7 am y las 5 pm es de 10 horas (5+5).

(English)

A clock, often known as a timepiece, is a device that measures and displays the passage of time.

The clock works in 12 hours time period, therefore, the time between 7 am and 12 pm is 5 hours, similarly, the time between 12 pm and 5 pm is 5 hours.

Thus, the total hours between 7 am and 5 pm is 10 hours(5+5).

(Spanish)

¿Qué es un reloj?

Un reloj, a menudo conocido como reloj, es un dispositivo que mide y muestra el paso del tiempo.

El reloj funciona en un período de tiempo de 12 horas, por lo tanto, el tiempo entre las 7 am y las 12 pm es de 5 horas, de manera similar, el tiempo entre las 12 pm y las 5 pm es de 5 horas.

Así, el total de horas entre las 7 am y las 5 pm es de 10 horas (5+5).

Step-by-step explanation:

Answer:

The null hypothesis is [tex]H_o: p \leq 0.2[/tex]

The alternate hypothesis is [tex]H_a: p > 0.2[/tex]

The pvalue of the test is 0.1515 > 0.01, which means that we do not reject the null hypothesis that 20% of less users develop nausea, that is, we have no sufficient evidence that this proportion is larger than 20%.

Step-by-step explanation:

Test the claim that more than 20% of users develop nausea

This means that the null hypothesis is that 20% or less of the users develop nausea, that is:

[tex]H_o: p \leq 0.2[/tex]

And the alternate hypothesis is that more than 20% develop, so:

[tex]H_a: p > 0.2[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

0.2 is tested at the null hypothesis:

This means that [tex]\mu = 0.2, \sigma = \sqrt{0.2*0.8}[/tex]

Suppose 229 subjects are treated with a drug that is used to treat pain and 52 of them develop nausea.

This means that [tex]n = 229, X = \frac{52}{229} = 0.2271[/tex]

Value of the test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.2271 - 0.20}{\frac{\sqrt{0.2*0.8}}{\sqrt{229}}}[/tex]

[tex]z = 1.03[/tex]

Pvalue of the test an decision:

Probability of finding a proportion above 0.2271, which is 1 subtracted by the pvalue of z = 1.03

Looking at the z-table, z = 1.03 has a pvalue of 0.8485

1 - 0.8485 = 0.1515

The pvalue of the test is 0.1515 > 0.01, which means that we do not reject the null hypothesis that 20% of less users develop nausea, that is, we have no sufficient evidence that this proportion is larger than 20%.

Answer:

a = 9

b = 19

Step-by-step explanation:

DO B FIRST

The mean is the average of all the terms (numbers) in the sequence

To find the average you find the sum of the terms and divided the sum by the number of terms there are.

The mean times the number of terms equals the sum of all the terms subtract the terms that you know from the sum to get A

a = 17(10)-7-12-15-17-19-20-22-24-25

a = 170-161

a = 9

The median is found by taking the average of the two middle terms

Our middle terms are 17 and B

the median times 2 equals the sum of the two terms and then subtract the term you know from the sum

b = 18(2)-17

b = 36-17

b = 19

Answer:

The answer is "0.142466".

Step-by-step explanation:

Using the p formula for the proportion of nonconforming units through the subgrouping which can vary in sizes:

[tex]p =\frac{np}{n}\\\\[/tex]

[tex]\bar{p}=\frac{\Sigma np}{\Sigma n}\\\\[/tex]

Defects [tex]= \frac{5}{100} \times 50 \\\\[/tex]

[tex]p = \frac{5}{100} \times \frac{50}{50}=0.05\\\\[/tex]

It calculates the controls limits through the p-chart that is:

[tex]UCL_{p},LCL_{p}=\bar{p} \pm \sqrt{\frac{\bar{p}(1-\bar{p})}{\bar{n}}}\\\\[/tex]

So, the upper control limits:

[tex]= 0.05 + 3 \times \sqrt{(\frac{0.05\times(1-0.05)}{50})} \\\\= 0.142466[/tex]

Answer:

54.55%

Step-by-step explanation:

If he drank 10 ounces, that means he has 12 ounces of the tea left.

Find the percent that he has left by dividing 12 by 22, and multiplying it by 100

(12/22) x 100

= 54.55

So, Ian has approximately 54.55% left of his iced tea

Here's the steps for factoring by grouping:

[tex]7ax-7bz-2ay+2by[/tex]

[tex]=7x(a-b)-2y(a-b)[/tex]

[tex]=(7x-2y)(a-b)[/tex]

This is far as this expression can be factored. Let me know if you need any clarifications, thanks!

Factorizing the given expression we get, 7ax-7bx-2ay+2by = (a-b)(7x-2y)

Prime factorization is a mathematical technique to express a number or polynomial as the product of their prime factors.

Here given expression is 7ax-7bx-2ay+2by

Now grouping by like wise term the expression we get,

7ax-7bx-2ay+2by

= (7ax-7bx) - (2ay-2by)

= 7x(a-b) - 2y(a-b), taking the like terms as common

= (a-b)(7x-2y), again taking common the like wise term.

Hence the required factorization is given by,

7ax-7bx-2ay+2by = (a-b)(7x-2y)
