(a) Example question: "How often do you look at social media while doing schoolwork?

(b) Sofie can select a simple random sample of students by using a random number generator to assign a unique identification number to each student in the online high school.

(c) The sample for Sofie's research is the 32 completed surveys she received. These surveys represent the responses of a subset of the population. The population, in this case, refers to all the students at the online high school.

(d) If Sofie uses only the completed surveys, she can conclude that approximately 50% (16 out of 32) of the students who completed the survey reported using social media while doing schoolwork.

(a) Please select one of the following options: never, rarely, occasionally, frequently, or always."

(b) She can then use the random number generator again to select a specific number of students from the entire population of students, ensuring that each student has an equal chance of being selected. For example, if there are 500 students in total and Sofie wants a sample size of 50, she can generate 50 random numbers and select the corresponding students based on their identification numbers.

(d) However, it is important to note that this conclusion is specific to the sample of completed surveys and cannot be generalized to the entire population of high school students.

To make an inference about the percent of all high school students who use social media while doing schoolwork, Sofie would need a larger and more representative sample that covers a wider range of students in the online high school.

Additionally, she should consider potential biases in the sample, such as non-response bias if the students who chose not to complete the survey have different social media usage patterns compared to those who did respond.

Answer:

120.00

Step-by-step explanation:

Let x be the original price

The price is 10% off, or we pay 90% of the original price

.9 x

Then we have to pay 7% sales tax

.9x * 7%

.9x * .07

.063x is the tax

Add this to the .9x we have to pay for the jacket

.9x + .063x = .963x

This is the cost of the jacket

.963x = 115.56

Divide each side by.963

.963x/.963 = 115.56/.963

x =120.00

The cost of the jacket before discount and tax is 120.00

Answer: a. 36-17 <0.04x ⇒ 475 < x

b. When the number of calls is higher than 475 , Plan 1 is more economical than Plan 2.

Step-by-step explanation:

Hi, to answer this question we have to write an inequality:

The cost of plan 1 (36) must be less (<) than the cost of plan 2 (fixed charge [17] plus the product of the charge per call [0.04] and the number of calls [x] )

a.36 < 17+ 0.04x

Solving for x

36-17 <0.04x

19 < 0.04x

19 /0.04 <x

475 < x

b. When the number of calls is higher than 475 , Plan 1 is more economical than Plan 2.

If a test statistic does not fall in the rejection region when a false null hypothesis is being tested, it means that the null hypothesis cannot be rejected at the chosen level of significance.

In hypothesis testing, the rejection region is the set of all possible test statistic values that are unlikely to occur if the null hypothesis is true. If the test statistic falls within this region, then the null hypothesis is rejected in favor of the alternative hypothesis.

However, if the test statistic falls outside the rejection region, it means that the observed data is consistent with the null hypothesis. In other words, the data does not provide enough evidence to reject the null hypothesis at the chosen level of significance.

Answer:

We can start by isolating the variable "h".

5 8 h + 1 1 2 = 5

Subtracting 11/2 from both sides:

5 8 h = 5 - 1 1 2

Simplifying:

5 8 h = 8 1 2

Dividing both sides by 5/8:

h = 8 1 2 ÷ 5 8

Converting the mixed number to an improper fraction:

h = (8 x 8 + 1) ÷ 5 8

h = 65/8

Now, we can convert this fraction to a mixed number:

h = 8 1/8

Brigid has already picked for 8 1/8 hours, so the amount of time needed to pick the remaining strawberries is:

5 - (1 1/2 + 5/8 x 8) = 5 - (3 5/8) = 1 3/8

Therefore, Brigid still needs to pick for 1 3/8 hours to fill 5 bushels of strawberries. The answer is 1 and 3/8 hours or 2 and 3/16 hours (if simplified).

Answer:

Aceleracion = 4 m/s²

Step-by-step explanation:

Dados los siguientes datos;

Velocidad inicial = 10 m/s

Velocidad final = 70 m/s

Tiempo, t = 12 segundos

Para encontrar la aceleración;

Aceleración se puede definir como la tasa de cambio de la velocidad de un objeto con respecto al tiempo.

Matemáticamente, la aceleración viene dada por la fórmula;

\( Aceleracion = \frac{final \; velocidad - inicial \; velocidad}{tiempo}\)

Sustituyendo en la fórmula, tenemos;

\( Aceleracion = \frac{60 - 0}{15}\)

\( Aceleracion = \frac{60}{15}\)

Aceleracion = 4 m/s²

The change in the $941 salary to $787 will primarily impact the mean salary, reducing its value. The median and mode will remain unaffected.

If the $941 salary changes to $787, the new set of weekly salaries for the 7 employees would be: 556, 614, 689, 733, 742, 786, 787.

The main effect of this change is that the highest salary in the dataset has decreased. Initially, the highest salary was $941, but after the change, it becomes $787. This change will affect various summary measures of the dataset.

The mean or average salary will be affected by this change. The mean is calculated by summing all the salaries and dividing by the total number of salaries. Since the highest salary has decreased, the sum of all salaries will also decrease, leading to a decrease in the mean.

The median salary, which is the middle value in the ordered list of salaries, will remain the same. In this case, the median is 733, and since the $787 salary is still lower than the median, it will not affect its value.

The mode, which represents the most frequently occurring salary, will remain unchanged as well. In this dataset, there is no mode since all the salaries are different.

Overall, the change in the $941 salary to $787 will primarily impact the mean salary, reducing its value. The median and mode will remain unaffected.

In this scenario, the domain would be the set of all possible values for the amount of time it takes Sammy Speedster to drive from Houston to San Antonio. Since he is driving on a daily basis, the domain could be considered a continuous range from zero to some maximum value, perhaps 10 hours.

It's possible that Sammy could complete the trip in less than 3 hours if he were driving at a very high speed, but this would not be a common occurrence. Therefore, a reasonable domain could be considered to be between 3 and 10 hours.

The range, on the other hand, would be the set of all possible distances that Sammy could drive in the allotted time. Since we know that the distance is a constant 200 miles, the range would simply be 200 miles. It's possible that Sammy could drive more than 200 miles in a day if he were assigned additional routes, but this would not be relevant to this scenario.

In summary, a reasonable domain for Sammy's logbook would be between 3 and 10 hours, and the range would be a constant 200 miles.

The graph of y = x -7 is given below.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

Given:

The linear equation,

y = x -7.

Comparing with the slope-intercept form:

y = mx + b, where m is the slope and b is the y-intercept.

m = 1 and b = -7.

That means, when we draw the graph, we can rise 1 unit and run 1 unit.

Substitute the assumed value of x to get the value of y.

Put x = 0, we get,

y = -7.

And put x = 7, then y = 0

That means, (7,0) and (-7, 0) are the intercepting coordinates.

And the graph is given in the attached image.

Therefore, graph of y = x -7 is given.

Answer:

E = 58

F = 32

G = 90

Step-by-step explanation:

3x + 31 + 5x -13 + 90 = 180

3x + 31 + 5x -13 = 90

8x = 90 - 31 + 13

8x = 72

x = 72 / 8

x = 9

E = 3(9) + 31 = 27+31 = 58

F = 5(9)-13 = 45 - 13 = 32

G = 90

If cosθ=-3/4 and tanθ is negative, then sinθ= √(7)/4.

Since cosθ = -3/4 and θ is an angle in the second quadrant where cosθ is negative, we know that sinθ must be positive.

The Pythagorean identity is a trigonometric identity that relates the three basic trigonometric functions: sine, cosine, and tangent

To find sinθ, we can use the Pythagorean identity

sin^2θ + cos^2θ = 1

Substituting the value of cosθ we get

sin^2θ + (-3/4)^2 = 1

Simplifying

sin^2θ + 9/16 = 1

sin^2θ = 7/16

Taking the square root of both sides, we get

sinθ = ±√(7)/4

Since we know that sinθ is positive in the second quadrant, we take the positive value

sinθ = √(7)/4
