Answer:

57 = 33+24 = 3a+3c

Step-by-step explanation:

Let a= adults, c = children

total costs = 11a+8c

57 = 33+24 = 3a+3c

Answer: We can use the variables x and y to represent the number of adult tickets and children's tickets, respectively. The cost of adult tickets is $11 each and the cost of children's tickets is $8 each. So, we can use the following equation to represent the total cost for the movie tickets:

C = 11x + 8y

Where C is the total cost of the tickets, x is the number of adult tickets and y is the number of children's tickets

One combination of tickets that would total $57 is:

C = 11x + 8y = $57

x + y = 7 (number of tickets)

One way to satisfy this equation is to have 5 adult tickets and 2 children's tickets

x = 5

y = 2

C = 115 + 82 = $57

So, 5 adult tickets and 2 children's tickets is one combination that would total $57.

Answer:An edge is where two faces meet. A vertex is a corner where edges meet.

Step-by-step explanation:

The probability that at least two of the balls have the same number is 27.40%

Probability is the function that measures the chances that an outcome of a random event will be as expected. In this way you can measure how likely it is that an event will happen.

Probability requested is equivalent to:

P(at least 2 have same number) = 1 - P(no 2 have the same number)

P(no 2 have same number) = No. of ways to succeed / No. of possible outcomes

No. of ways to succeed = 90P8

No. of possible outcomes = 90^8

No. of ways to succeed =

nPr = n! / (n-r)!

90P8 = 90! / (90-8)!

90P8 = 90! / (82)!

90P8 = 90*89*88*87*86*85*84*83*82! / [(82)!

90P8 = 90*89*88*87*86*85*84*83

90P8 = 3.13x10^15

P(no 2 have same number) = 3.13x10^15 / 90^8

P(no 2 have same number) = 0.73

P(at least 2 have same number) = 1 - P(no 2 have the same number)

P(at least 2 have same number) = 1 - 0.73

P(at least 2 have same number) = 0.2740 = 27.40%

Answer:wheres the diagram?

Step-by-step explanation:

The woman at the dinner party consumed 24 fluid ounces of wine containing approximately 4.8 standard drinks assuming the wine had an alcohol content of 12%. She exceeded the recommended limit for moderate drinking on that day.

Assuming each glass of wine contained 8 fluid ounces, the woman consumed a total of 24 fluid ounces of wine throughout the evening.

To determine the number of standard drinks ingested, we need to know the alcohol content of the wine. In the United States, a standard drink is defined as containing 0.6 fluid ounces or 14 grams of pure alcohol.

Assuming the wine had an alcohol content of 12% (which is a typical percentage for table wine), we can calculate the number of standard drinks ingested by using the following formula:

Number of standard drinks = (Volume of alcohol consumed in ounces x % alcohol by volume) / (0.6 ounces of alcohol per standard drink)

Number of standard drinks = (24 fl oz x 0.12) / 0.6 fl oz

Number of standard drinks = 4.8

Therefore, the woman consumed approximately 4.8 standard drinks.

To determine if she drank alcohol in moderation, we need to consider the recommended limits for moderate drinking. According to the National Institute on Alcohol Abuse and Alcoholism, moderate drinking is defined as up to one drink per day for women.

Since the woman consumed 4.8 standard drinks in one evening, she exceeded the recommended limit for moderate drinking for that day.

The probability of a randomly selected dog being deaf is 0.194.

Given that 8% of dogs in a certain breed are white and if a dog is white, the probability it will be deaf is 70% while if it is not completely white, the probability of deafness is 15%.

Let A = The probability that a randomly selected dog is white.

A = 8% = 0.08.

Let B = The probability that a randomly selected white dog is deaf.

B = 70% = 0.70.

Let C = The probability that a randomly selected non-white dog is deaf.

C = 15% = 0.15.

Now, the probability of a randomly selected dog being deaf can be calculated as follows;`

P(dog is deaf) = P(white dog is deaf) + P(non-white dog is deaf)`

We know that `P(white dog) = 0.08` and `P(non-white dog) = 1 - P(white dog) = 1 - 0.08 = 0.92`

Therefore, the probability of a randomly selected dog being deaf is:

P(dog is deaf) = P(white dog is deaf) + P(non-white dog is deaf)`

P(dog is deaf) = (P(white dog) × P(white dog is deaf)) + (P(non-white dog) × P(non-white dog is deaf))`

Substituting the respective probabilities in the above equation, we get:

P(dog is deaf) = (0.08 × 0.70) + (0.92 × 0.15)P(dog is deaf) = 0.056 + 0.138 = 0.194

Therefore, the probability of a randomly selected dog being deaf is 0.194.

The only claim that would tend to be refuted by the 90% confidence interval of 135 to 160 is B) The population mean is 125.

The 90% confidence interval for the mean of a population being computed to be 135 to 160 means that if we were to take multiple samples from the population and compute the mean of each sample, 90% of the intervals we construct would contain the true population mean. Therefore, any claim that falls outside of this interval would tend to be refuted.

Let's consider the options.

A) The population mean is 145.
This claim falls within the 90% confidence interval of 135 to 160, so it is not refuted by the interval.

B) The population mean is 125.
This claim falls outside of the 90% confidence interval of 135 to 160, so it is refuted by the interval.

C) The population mean is 170.
This claim also falls outside of the 90% confidence interval of 135 to 160, so it is refuted by the interval.

D) The population mean is between 130 and 150.
This claim falls within the 90% confidence interval of 135 to 160, so it is not refuted by the interval.

Therefore, the only claim that would tend to be refuted by the 90% confidence interval of 135 to 160 is B) The population mean is 125.
A 90% confidence interval for the mean of a population, computed to be 135 to 160, provides a range in which we can be 90% confident that the true population mean lies. This confidence interval helps us make inferences about the population based on sample data. The given interval would tend to refute any claim that falls outside of this range.

For example, if someone claims that the population mean is either below 135 or above 160, this confidence interval would challenge that assertion. Since we are 90% confident that the true population mean falls between 135 and 160, it would be statistically unlikely for the actual mean to be outside of this range. In conclusion, any claim suggesting a population mean outside the 135 to 160 interval would be refuted by this 90% confidence interval.

Answer:

Angle 1 = 115 degrees

Angle 2 = 65 degrees

Step-by-step explanation:

Angle 1: Same-side interior angle of Line 1

Angle 2: Same-side interior angle of Line 2

We know that the difference between the angles is 50 degrees. Since the angles are supplementary, we can write the equation:

Angle 1 + Angle 2 = 180

Now, we need to express the difference between the angles in terms of Angle 1 or Angle 2. We can choose either angle, so let's express it in terms of Angle 1:

Angle 1 - Angle 2 = 50

We can rewrite this equation as:

Angle 1 = 50 + Angle 2

Now substitute this expression for Angle 1 into the first equation:

(50 + Angle 2) + Angle 2 = 180

Combine like terms:

2Angle 2 + 50 = 180

Subtract 50 from both sides:

2Angle 2 = 130

Divide by 2:

Angle 2 = 65

Now substitute this value back into the equation for Angle 1:

Angle 1 = 50 + Angle 2

Angle 1 = 50 + 65

Angle 1 = 115

Therefore, the angles are as follows:

Angle 1 = 115 degrees

Angle 2 = 65 degrees

The limit of the function as (x,y) approaches (0,0) which is lim (x,y)→(0,0) (x^2y+ xy^2) /(x^3−y^3) does not exist.

To find the limit of the given function as (x,y) approaches (0,0), we can try approaching along different paths and check if the limit exists and is the same along all paths.

Let's try approaching along the x-axis, i.e., setting y=0:

lim (x,0)→(0,0) (x^20 + x0^2)/(x^3-0^3) = lim (x,0)→(0,0) 0/ x^3 = 0

Similarly, approaching along the y-axis, i.e., setting x=0:

lim (0,y)→(0,0) (0y + y^20)/(0^3-y^3) = lim (0,y)→(0,0) 0/ (-y^3) = 0

Now, let's try approaching along the line y=x:

lim (x,x)→(0,0) (x^2x + xx^2)/(x^3-x^3) = lim (x,x)→(0,0) 2x/0

The answer is true. The goal of a hypothesis test is indeed to demonstrate that the patterns observed in the sample data are not simply due to chance or sampling error, but rather represent real patterns in the population.

Hypothesis testing is a statistical tool used to determine whether a hypothesis about a population parameter is supported by sample data. The hypothesis being tested is called the null hypothesis, which assumes that there is no significant difference or relationship between variables in the population. The alternative hypothesis, on the other hand, suggests that there is a significant difference or relationship.

Through hypothesis testing, we can determine whether the observed differences or relationships in the sample are likely to occur by chance or are actually reflective of the true population. If the p-value (the probability of obtaining a result as extreme as the one observed, assuming the null hypothesis is true) is less than a predetermined level of significance, typically 0.05, we reject the null hypothesis and conclude that the alternative hypothesis is supported by the data.

In summary, the goal of a hypothesis test is to provide evidence that the observed patterns in the sample data are reflective of the true population and not just due to chance or sampling error.

Hi there!

Let's solve for c.

\(\left(5x\ +\ 4\right)\left(2x\ +\ c\right)\ =\ 10x^{2\ }+\ nx\ -\ 12\)

Step 1: Add \(-10x^2\) to both sides.

\(5cx + 10x^2 + 4c + 8x + -10x^2 = nx + 10^2 - 12 + -10x^2\)

\(5cx + 4c + 8x = nx - 12\)

Step 2: Add \(-8x\) to both sides.

\(5cx + 4c + 8x + -8x = nx - 12 + -8x\)

\(5cx + 4c = nx - 8x - 12\)

Step 3: Factor out variable c.

\(c(5x + 4) = nx - 8x - 12\)

Step 4: Divide both sides by \(5x+4\).

Answer:

c = 3 and n = - 7

Step-by-step explanation:

Expand the left side and compare the coefficients of like terms on both sides.

(5x + 4)(2x - c) ← expand using FOIL

= 10x² - 5cx + 8x - 4c ← factor out x from each of the terms in x

= 10x² + x( - 5c + 8) - 4c

Given this is equal to 10x² + nx - 12, then

Comparing the constant terms

- 4c = - 12 ( divide both sides by - 4 )

c = 3

Comparing the coefficients of the x- terms

n = - 5c + 8 = - 5(3) + 8 = - 15 + 8 = - 7

Thus

c = 3 and n = - 7
