Answers

Answer 1

Answer:

Answer:

If an amount is included as a "Gratuity" or "Service Charge," tipping is not required. ... If the tip is included, the breakdown of the bill will read "gratuity" or "service charge," which means that a tip is already included.

HELP ME I WILL GIVE BRAINLIEST California has a population of approximately 4 × 10^7 people and South Dakota has a population of approximately 8 × 10^5 people.

Answers

The population in California is 50 times greater than the population in South Dakota.

The number of times the population in California is higher than that in South Dakota

To find out how many times greater the population in California is than in South Dakota, you can divide the population of California by the population of South Dakota:

Population of California = 4 * 10⁷

Population of South Dakota = 8 * 10⁵

Population ratio = (Population of California) / (Population of South Dakota)

Population ratio = (4 * 10⁷) / (8 * 10⁵)

Population ratio = 50

Therefore the population in California is 50 times greater than the population in South Dakota.

A town interested in installing wind turbines to generate electricity measures the speed of the wind in the town over the course of a year. They find that most of the time, the wind speed is pretty slow, while only rarely does the wind blow very fast during a storm. What would be the best measure of the central wind speed they should report to the mayor? The mean, because the distribution of wind speeds is skewed. The median, because the distribution of wind speeds is symmetric. The mean, because the distribution of wind speeds is symmetric. The median, because the distribution of wind speeds is skewed. The proportion, because the distribution of wind speeds is skewed. The proportion, because the distribution of wind speeds is symmetric.

Answer:

The median, because the distribution of wind speeds is skewed.

Step-by-step explanation:

A few higher speeds will raise the mean. For a skewed distribution, the median may be a more appropriate measure of center.

Additional comment

From an engineering point of view, one might have to consider speeds only within some range, as the wind turbines may be shut down for speeds too low or too high. Likely the power generated is not proportional to speed, so a weighted average (of the square of speed) would probably be more useful. Unfortunately, this question does not get into such subtleties.

TV advertising agencies face growing challenges in reaching audience members because viewing TV programs via digital streaming is increasingly popular. the Harris poll reported on November 13, 2012, that 53% of 2343 American adults surveyed said they have watched digitally streamed TV programming on some type of device.a. calculate and interpret a confidence interval at the 99% confidence level for the proportion of all adult americans who have watched streamed programming.b. what sample size would be required for the width of a 99% CI to be at most .05 irrespective of the value of p?

Answers

Answer:

a) The 99% confidence interval would be given (0.503;0.557).

We are 99% confident that this interval contains the true population proportion.

b) $n=(0.53(1-0.53))/(((0.05)/(2.58))^2)=663.2$

And rounded up we have that n=664

Step-by-step explanation:

Data given and notation

n=2343 represent the random sample taken

X represent the people that they have watched digitally streamed TV programming on some type of device

$\hat p=0.53$ estimated proportion of people that they have watched digitally streamed TV programming on some type of device

$\alpha=0.01$ represent the significance level

Confidence =0.99 or 99%

z would represent the statistic for the confidence interval

p= population proportion of people that they have watched digitally streamed TV programming on some type of device

The population proportion present the following distribution:

$p \sim N (p, \sqrt{(p(1-p))/(n)}$

Part a) Confidence interval

The confidence interval would be given by this formula

$\hat p \pm z_(\alpha/2) \sqrt{(\hat p(1-\hat p))/(n)}$

For the 99% confidence interval the value of $\alpha=1-0.99=0.01$ and $\alpha/2=0.005$ , with that value we can find the quantile required for the interval in the normal standard distribution.

$z_(\alpha/2)=2.58$

And replacing into the confidence interval formula we got:

$0.53 - 2.58 \sqrt{(0.53(1-0.53))/(2343)}=0.503$

$0.53 + 2.58 \sqrt{(0.53(1-0.53))/(2343)}=0.557$

And the 99% confidence interval would be given (0.503;0.557).

We are 99% confident that this interval contains the true population proportion.

Part b) What sample size would be required for the width of a 99% CI to be at most 0.05 irrespective of the value of p??

The margin of error for the proportion interval is given by this formula:

$ME=z_(\alpha/2)\sqrt{(\hat p (1-\hat p))/(n)}$ (a)

And on this case we have that $ME =\pm 0.05$ and we are interested in order to find the value of n, if we solve n from equation (a) we got:

$n=(\hat p (1-\hat p))/(((ME)/(z))^2)$ (b)

And replacing into equation (b) the values from part a we got:

$n=(0.53(1-0.53))/(((0.05)/(2.58))^2)=663.2$

And rounded up we have that n=664

3 cards are drawn from a standard deck of 52 playing cards. How many different 3-card hands are possible if the drawing is done without replacement?

Answers

Since you start with 52 cards, and are drawing 3 cards you multiply 52 * 51 * 50 then divide that product by 3 * 2 because it doesn’t matter what order the cards are drawn in. 52 * 51 * 50/ 3 * 2 = 22,100 different combinations of 3 cards

What is the product? 2x+8 x2 + 3x-4 x(x-4)(x-1) 20x+4) 2 (x+4)(x-4) 2x(x-1) 2x(x+4)

Answers

The products of the given expressions are:

$(2x + 8) * (x^2 + 3x - 4) = 2x^3 + 14x^2 + 16x - 32\n(x - 4)(x - 1)(20x + 4) = 20x^3 - 96x^2 + 60x + 16\n2(x + 4)(x - 4) = 2x^2 - 32\n2x(x - 1) = 2x^2 - 2x\n2x(x + 4) = 2x^2 + 8x$

Here, we have to find the product of the expressions given,

let's multiply them step by step:

$(2x + 8) * (x^2 + 3x - 4):$

First, apply the distributive property:

$(2x + 8) * x^2 = 2x^3 + 8x^2\n(2x + 8) * 3x = 6x^2 + 24x\n(2x + 8) * (-4) = -8x - 32$

Now, add the results:

Product of (2x + 8) and $(x^2 + 3x - 4) = 2x^3 + 8x^2 + 6x^2 + 24x - 8x - 32$

Combine like terms:

Product = $2x^3 + (8x^2 + 6x^2) + (24x - 8x) - 32$

Product = $2x^3 + 14x^2 + 16x - 32$

(x - 4)(x - 1)(20x + 4):

First, apply the distributive property:

$(x - 4)(x - 1) = x^2 - x - 4x + 4 = x^2 - 5x + 4$

Now, multiply the result with (20x + 4):

$(x^2 - 5x + 4)(20x + 4) = 20x^3 + 4x^2 - 100x^2 - 20x + 80x + 16$

Combine like terms:

Product = $20x^3 + (4x^2 - 100x^2) + (-20x + 80x) + 16$

Product = $20x^3 - 96x^2 + 60x + 16$

2(x + 4)(x - 4):

First, apply the distributive property:

2(x + 4) = 2x + 8

Now, multiply the result with (x - 4):

$(2x + 8)(x - 4) = 2x^2 + 8x - 8x - 32$

Combine like terms:

Product = $2x^2 + (8x - 8x) - 32$

Product = $2x^2 - 32$

2x(x - 1):

Apply the distributive property:

$2x * x = 2x^2$

2x * (-1) = -2x

Combine the terms:

Product = $2x^2 - 2x$

2x(x + 4):

Apply the distributive property:

$2x * x = 2x^2$

2x * 4 = 8x

Combine the terms:

Product = $2x^2 + 8x$

So, the products of the given expressions are:

$(2x + 8) * (x^2 + 3x - 4) = 2x^3 + 14x^2 + 16x - 32\n(x - 4)(x - 1)(20x + 4) = 20x^3 - 96x^2 + 60x + 16\n2(x + 4)(x - 4) = 2x^2 - 32\n2x(x - 1) = 2x^2 - 2x\n2x(x + 4) = 2x^2 + 8x$
