3/10

Step-by-step explanation:

2 cans of tomato soup, 3 cans of chicken noodle soup, 2 cans of Italian wedding soup, 2 cans of potato soup, & 1 can of split pea soup = 10 cans of soup

P( chicken noodle soup) = cans of chicken noodle soup / total cans

The fraction of a pound of granola Marty buys is 3/4.

A fraction is a part of a whole number, value, and variable.

There are proper and improper fractions, including complex fractions.

Proper fractions are those with the numerator less than the denominator. An improper fraction produces a whole number with a remainder when the denominator divides the numerator.

On the other hand, complex fractions are rational expressions that have some fractions in their numerators, denominators, or both.

1 pound = 16 ounces

The quantity of granola Marty buys = 12 ounces

The fraction of a pound of granola Marty buys = 3/4 (12/16)

Thus, we can conclude that Marty buys 3/4 or 75% of a pound of granola.

The distance 4450× 10⁶ km between the Neptune and the sun in AU is 29.75 AU

The astronomical unit is a unit of length, roughly the distance from Earth to the Sun and approximately equal to 150 million kilometres or 8.3 light-minutes. The actual distance from Earth to the Sun varies by about 3% as Earth orbits the Sun, from a maximum to a minimum and back again once each year.

An astronomical unit is the average distance between the Earth and the Sun. Estimates of this distance have varied over time. It is now defined as exactly 149,597,870.7 kilometers.

if 149,597,870.7 kilometers = 1 AU

then 4450× 10⁶ km = 4450× 10⁶ ÷149,597,870.7

= 29.75 AU

By solving the system using elimination method 5x + 4y = 12 and 3x -3y = 18 we get x = 4 and y = -2.

What is Elimination Method?

To create an equation in one variable using the elimination approach, you can either add or subtract the equations. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are in equality.

Now solving the both equation by using elimination method;

5x +4y = 12                                                     ----------------------------eq(1)

3x - 3y = 18                                                     ----------------------------eq(2)

Multiply equation (1) by 3 and equation (2) by 4,  we get;

15x + 12y = 36

12x - 12y = 72

Now, same equation will beb together;

15x + 12y + 12x - 12y = 36 + 72

15x + 12x = 36 + 72

27x = 108

x = 108/27

x = 4

Now, we calculate for the y ;

3x - 3y = 18

3 * 4 - 3y = 18

12 - 3y = 18

12 - 18 = 3y

3y = -6

y = -6/3

y = -2

(x, y) = (4, -2)

So, by solving the system using elimination method 5x + 4y = 12 and 3x -3y = 18 we get x = 4 and y = -2.

the ability to identify situations when sampling is appropriate and to draw the proper inferences about the population after the sample has been evaluated. The answer describes the process of selecting and evaluating a sample, including examples of stratified, random, and systematic sampling. It also discusses the limitations of not using a random sample in order to obtain unbiased results.

1. This is an example of stratified sampling, since the students are divided into three groups (Sophomores, Juniors, and Seniors) and a sample is taken from each group. This allows for a more representative sample of the overall population.

2. This is an example of random sampling, since each name has an equal chance of being selected from the bag. This ensures that the sample is unbiased and allows for a fair representation of the population.

3. This sampling plan results in a random sample, since the schools were randomly selected from the district. A random sample ensures that every member of the population has an equal chance of being selected.

4. This sampling plan results in a systematic sample, since the polling company selected every 20th person from the list. Systematic sampling allows for a more representative sample of the population, since it ensures that each person in the population is equally likely to be selected.

5. This sampling plan does not result in a random sample, since only the female employees who attended the meeting were selected. This means that those who did not attend the meeting had no chance of being selected in the sample, thus biasing the results.

This answer demonstrates the ability to identify situations when sampling is appropriate and to draw the proper inferences about the population after the sample has been evaluated.

Total time is taken =  20mins 20/60=0.33hr

Note:

Odometer reading is the distance covered while straight-line distance is the displacement which is the shortest route

Distance is a scaler where as displacement is a vector quantity.

Scaler has only magnitude while vector has magnitude and direction.

We have to find the average velocity.

Average velocity = Ratio of total displacement and total time.

⇒ Average velocity (v) = displacement/time.

The impulse equation is given by pf = p0 + ∫tL₀F(t)dt. With the given information, the integral is ∫tL₀(-28t² + 7.0)dt.

This integral can be solved using the power rule for integration, which states that the integral of xⁿ is xⁿ⁺¹/(n+1). Thus, the integral of -28t² + 7.0 is -28/3t³ + 7t. This can be evaluated from t=0 to t=0.5 to get the change in momentum due to the applied impulse. Substituting the values into the impulse equation, pf = 0 + (-28/3(0.5)³ + 7(0.5)) = -2.167.

a) Using the summation notation to write the sum is 3∑n=1 3n.

b) The total amount that Jummy will save during the first 3 weeks of his new job is $18.

The summation notation is the representation of a series in a compact form, using the capital sigma symbol (Σ) to indicate the sum of a number of similar terms.

Using the summation notation, one can write a long sum in a single expression.

In this situation, the expression can be read as the sum of 3n as n goes from week 1 to week 3, representing the first three weeks Jimmy will spend on the job.

3∑n=1 3n

= 3 x 1 + 3 x 2 + 3 x 3

Answer:

The given sample of the randomly selected players from the teams as described is a stratified sample. Hence, the right answer is option A.

In a stratified sample, the population is divided into groups (or strata) based on some characteristic, and a random sample is selected from each group. In this case, the population is the football players, and the groups are the varsity and junior varsity teams. The coach randomly selects one of these teams and then asks all players from that team their opinion on a new logo.

This type of sampling is used when the population is divided into subgroups that are different in some way, and the researcher wants to ensure that these subgroups are represented in the sample. In this case, the coach wants to ensure that both varsity and junior varsity players are represented in the sample, as they may have different opinions on the new logo.

It's not a simple random sample because he selected the team first and then the players. Also, it's not a voluntary response sample because the coach is selecting the players.

It's not a cluster sample because the coach is not selecting the players based on location or geographic proximity, and it's not a systematic sample because he is not selecting the players based on the order in which they appear in a list or a database.

The points where the lines representing the intersection of two linear equations intersect are referred to as the solution of a linear equation.

In other words, the set of all feasible values for the variables that satisfy the specified linear equation constitutes the solution set of the system of linear equations.

Given, the line's points are (2,9), (3,10), (4,11), and (5,12). (6,13)

Assuming that the line's equation is y=x+7, adding the points to the equation results in
