Can someone help me, I have this assignment due tomorrow and my teacher is absent.

Answer:

l'argent total est de 2600 $.

Step-by-step explanation:

On sait que 250 $ représentent 5/52 de l'argent total.

On peut donc utiliser une règle de trois pour trouver l'argent total :

5/52 correspond à 250 $

1 correspond à x (l'argent total)

On peut écrire cette proportion sous forme d'équation :

5/52 = 250 $/x

Pour isoler x (l'argent total), on peut multiplier les deux membres de l'équation par x :

5/52 * x = 250 $

On peut ensuite multiplier les deux membres de l'équation par le dénominateur de la fraction 5/52, c'est-à-dire 52 :

5 * x = 52 * 250 $

Enfin, on divise les deux membres de l'équation par 5 pour isoler x :

x = 52 * 250 $ / 5

x = 2600 $

Ainsi, l'argent total est de 2600 $.

Based on the provided information, a) bias is introduced through convenience sampling there could be specific variable associated with the first hundred students. It can be avoided by simple random sampling. b) bias is introduced through wording as it includes a negative consequence. It can be avoided by just asking for an opinion without any associated reasoning or consequences.

Bias refers to a deviation of feedback which is based on certain influences by the surveyor and respondent. Sampling bias or selection bias refers to a type of bias in which a researcher gathers a sample of respondents for a questionnaire that does not accurately represent the population. Survey bias refers to the way the question is phrased or formatted, leading people to choose a certain answer instead of another. In the given case,

a) A bias may have been introduced based on the way the convenience sample was selected as there could be specific variable associated with each of the first hundred students that walk into the dining room. The first hundred students could possibly like the food and that is the reason why they come early to the dining room. Selecting students at the dining room may also exclude the students who dislike the food and choose to eat elsewhere. A simple random sample can help avoid this bias. By randomly selecting students at the university campus would provide a more inclusive and true representation of the population.

b) A bias may have been introduced based on the way the question is worded is to maintain the current meal plan as it presents a negative consequence to introducing a new meal plan. It states that a new meal plan would result in more cost. In order to avoid bias, the survey should ask students opinion about the food without introducing any external reasoning.

hope this is right:)

the 10th term of the AP(Arithmetic Progression) is -233/46.

Given,

The sum of first 5 terms of an AP is 25 and the sum of the next 5 terms is -75, to find the 10th term.

Let us assume the first term of the AP is 'a' and the common difference be 'd'.

So, 2a + 4d + 6d + 8d + 10d

= 25 ⇒ 2a + 28d

= 25

Similarly, 12d + 14d + 16d + 18d + 20d

= -75 ⇒ 80d

= -75 - 12d ⇒ 92d

= -75 ⇒ d = -75/92

Now,

2a + 28d = 25 ⇒ 2a

= 25 - 28d ⇒ 2a

= 25 - 28(-75/92) ⇒ 2a

= 316/23 ⇒ a

= 158/23

Hence, the 10th term of the AP is a + 9d which is (158/23) + 9(-75/92) = -233/46

Therefore, the 10th term of the AP is -233/46.

The F-distribution is used to test the significance of the population coefficient of determination (option D).

The coefficient of determination, denoted as R², measures the proportion of the variance in the dependent variable that is explained by the independent variables in a regression model. It ranges from 0 to 1, where 0 indicates no relationship and 1 indicates a perfect relationship.

To determine the significance of R², the F-distribution is used. The F-test compares the variation explained by the regression model (numerator) to the unexplained or residual variation (denominator). It calculates the F-statistic, which is the ratio of the two variances.

The F-distribution provides critical values that allow us to determine whether the observed F-statistic is statistically significant or not. By comparing the calculated F-value with the critical value from the F-distribution, we can assess whether the coefficient of determination is significantly different from zero, indicating the presence of a meaningful relationship between the variables. The correct option is d.

Answer:

56 degrees and 34 degrees

Step-by-step explanation:

Well, considering the fact that complementary angles have a sum of 90 degrees, I think the equation we could use here to solve, would be:

90 - 22 = 68

68/2 = 34

Therefore 34 + (34 + 22) = 90

For two populations for which μ₁ = 31,σ₁ = 2, μ₂ = 27, and σ₂ = 4. The shape of the distribution is approximately normal. So, the correct choice for answer is option (b). The mean of normal distribution is equals to 4.

In statistics, the collected data distribution shape sometimes normal and sometimes non-normal. In testing of hypothesis, to use the test statistics we have to check whether data is normally or not. Here we have, two populations. In first population : mean μ₁ = 31,

standard deviations,σ₁ = 2,

sample size, n₁ = 49

In case of second sample, mean, μ₂ = 27,

standard deviations, σ₂ = 4.

Sample size, n₂ = 59

Since, population standard deviation are known and sample sizes are greater than 30, therefore the shape of the sampling distribution of the difference of sample means is approximately normal. The shape of the distribution is approximately normal. Mean of the sampling distribution of \( \bar x_1 - \bar x_2\) are

\(\mu_{ \bar x_1 - \bar x_2} = \mu_1 - \mu_2 \)

Answer:

5, or any value greater than or equal to 5

Step-by-step explanation:

So, let's start with the inequality: \(x < 5\) since it's something that has a value. This just means that x is less than 5... but in our compound inequality it's very important, since the other inequality is: \(x > c\),

so if we were to say: \(c=5\), then we would have the compound inequality: \(5 < c < 5\) and there is no value that would satisfy this inequality, because what value is between 5 and 5?

In general, if \(c\ge5\) than there will be no solutions, since x cannot be greater than or equal to 5, and also less than 5 at the same time.

How to solve linear equations?
Given that the largest power of the variable (or pronumeral) in these equations is 1, linear equations are also known as first-degree equations. A line on the quadratic system is represented by a linear equation. This equation's general form is axe + b = 0, where a, b, and x are all integers and x is the variable. The y-axis is parallel to this form of equation's single solution, which it symbolizes.
The steps that should be followed while solving linear equations are listed below:
1) We must first determine which variable we need to isolate.
2) Next, make a distinction between variables and constants.
3) Arrange the constants on the right and the variables on the left.
4) Using established axioms, we carry out algebraic operations to determine the variable's value.

Given, the equation is 6(8g + 2) + 45 = 153
Following the steps in the available literature, we have the equation as:
6(8g + 2) + 45 = 153 ⇒ 48g + 12 + 45 = 153 ⇒ 48g = 153 - 45 - 12 = 96
⇒ g = 96/48 ⇒ g = 2
Thus, g as suggested will determine number of times each family bowled.

The correct term for variation in characteristics within populations of the same species is "intraspecific variation."

In biology, a species is defined as a group of organisms that can interbreed and produce viable offspring. Within a species, there can be variation in characteristics due to genetic differences, environmental factors, or a combination of both.

This variation can occur within a single population or across different populations of the same species.

The term "intraspecific variation" is used to describe this variation within a single species. It can refer to differences in physical characteristics such as size, color, or shape, as well as differences in behavior, physiology, or genetic makeup.

Intraspecific variation is important because it can influence an organism's survival and reproduction, as well as its interactions with other organisms in its environment.

Understanding intraspecific variation is therefore important for studying evolutionary processes, population dynamics, and biodiversity.

Answer:

x = 1

y = 5

Step-by-step explanation:

5x - 2y = -5

5x + 6y = 35

=> 5x + 6y = 35

=> 5x - 5x + 6y = 35 - 5x

=> 6y = 35 - 5x

=> 6y/6 = 35/6 - 5/6x

=> y = 35/6 - 5/6x

=> 5x - 2 (35/6 - 5/6x) = -5

=> 5x - 35/3 + 5/3x = -5

=> 15/3x -35/3 + 5/3 = -15/3

=> 20/3x -35/3 = -15/3

=> 20/3x -35/3 + 35/3 = -15/3 + 35/3

=> 20/3x = 20/3

=> 20/3x * 3 = 20/3 * 3

=> 20x = 20

=> 20x/20 = 20/20

=> x = 1

=> 5x + 6y = 35

=> 5(1) + 6y = 35

=> 5 + 6y = 35

=> 5 -5 + 6y = 35 -5

=> 6y = 30

=> 6y/6 = 30/6

=> y = 5

So, x = 1
