what do we mean when we use the term "variable" in statistics

Answer:

g(-1)=5

Step-by-step explanation:

Put value of x, which is - 1

\(g(x) = 3 - 2x \\ g( - 1) = 3 - 2( - 1) \\ g( - 1) = 3 + 2 \\ g( - 1) = 5\)

Answer:

B. 5

Step-by-step explanation:

I. If g(x) = 3 - 2x and g( -1 )

    g(-1 ) => inside x value is -1

II. Solve by replace x.value with -1

      g(-1 ) = 3 - 2(-1)

               = 3 + 2

       g(-1 ) = 5

Step-by-step explanation:

For every hour she earns 12$

The correct statement about the graph is for each hour Lisa earns $12. This can be obtained by studying the graph.

By observing the graph we can say that Earnings are directly proportional to Time.

Taking any point on the graph, for example (24,2) we can say that for 2 hours Lisa earns $24 ⇒ for 1 hour she earns $12 .

Hence the correct statement about the graph is for each hour Lisa earns $12.

The “yearly tuition costs” as an independent variable which should be plotted on X-axis and “mid-career salary” as a dependent variable on Y-axis. The scatterplot is made of them.

Based on the table provided, it is possible to observe that there is not necessarily a clear relationship between the cost of tuition and mid-career salary.

While some of the colleges with higher tuition costs (such as MIT and Stanford) have high mid-career salaries, others (such as Harvey Mudd and Caltech) also have high mid-career salaries despite lower tuition costs. Additionally, some colleges with low or zero tuition costs (such as the US Naval Academy and West Point) also have high mid-career salaries.

Therefore, it is not safe to assume that a higher cost of tuition will necessarily translate into higher-paying jobs. The scatter plot of yearly tuition costs and mid-career salary is made.

Answer:

8/2 or 4/1

Step-by-step explanation:

To find the slope, you simply count how high up one point is from another (0,0 to 2,8) and then how far over. Since 2,8 is 8 points up from 0,0 the numerator of our slope would be 8; and since 8,2 is two over from 0,0 the denominator is 2. Simplify this to 4/1.

Question 24: A data visualization tool that updates in real time and gives multiple outputs is called - a data dashboard.

A data visualization tool that updates in real time and gives multiple outputs is called a data dashboard. What is a scatter plot? A scatter plot is a type of diagram used to display two variables on a two-dimensional plot. The positioning of data points on a scatter plot graphically depicts the correlation between the two variables. To construct a scatter plot, two variables (independent and dependent variables) are plotted on a graph.

The independent variable is plotted on the horizontal (x) axis and the dependent variable is plotted on the vertical (y) axis. A point is plotted for each pair of values, and the pattern of the points suggests a relationship between the two variables.A scatter plot is useful in displaying the correlation between two variables. The correlation is positive if the points are in an upward direction. The correlation is negative if the points are in a downward direction. A lack of correlation, or random points, is suggested by a scatter plot with no apparent pattern.

Answer:

44.10 = 2.1x

x = 21 miles

Step-by-step explanation:

Cost per mile = $2.1

Driver tip = $5

Total amount paid = $49.10

Let

x = number of miles

​Write an equation to determine the distance in miles \left(x\right)(x) between the airport and Anna's home.

Total cost of miles = Total amount paid - Driver tip

= $49.10 - $5

= $44.10

Equation to determine distance in miles

Total cost of miles = cost per mile * number of miles

44.10 = 2.1x

Find the distance between the airport and Anna's home

44.10 = 2.1x

Divide both sides by 2.1

44.10 / 2.1 = 2.1x / 2.1

21 = x

x = 21 miles

The probability density function (pdf) of the largest of the five waiting times is given by: f(x) = 4/10^5 * x^4, where x is a real number between 0 and 10. The expected value of the largest of the five waiting times is 8.33 minutes.

The pdf of the largest of the five waiting times can be found by considering the order statistics of the waiting times. The order statistics are the values of the waiting times sorted from smallest to largest.

In this case, the order statistics are X1, X2, X3, X4, and X5. The largest of the five waiting times is X5.

The pdf of X5 can be found by considering the cumulative distribution function (cdf) of X5. The cdf of X5 is given by: F(x) = (x/10)^5

where x is a real number between 0 and 10. The pdf of X5 can be found by differentiating the cdf of X5. This gives: f(x) = 4/10^5 * x^4

The expected value of X5 can be found by integrating the pdf of X5 from 0 to 10. This gives: E[X5] = ∫_0^10 4/10^5 * x^4 dx = 8.33

Answer:

Tax: $23.95

Total: $502.95

Explanation:

The tax that you have to pay is equal to 5% of $479. So, we can calculate the tax as follows:

So, you need to pay $23.95 for tax.

Then, in total, you pay the initial cost plus the sales tax, so:

$479 + $23.95 = $502.95

Therefore, the answers are $23.95 for tax and $502.95 in total.

Step-by-step explanation:

ac = 2√13 cm,bc = 2√13 cm,de = 4 cm

To solve the problem, let's use the given information and apply relevant formulas.

1) We are given that cm = 3√12 cm and hc = 4 cm. From this, we can find the lengths of ac, bc, and de.

In a right-angled triangle, the hypotenuse (ac) can be found using the Pythagorean theorem:

\(ac^2 = cm^2 + hc^2\)
\(ac^2 = (3√12)^2 + 4^2\)
\(ac^2 = 36 + 16\)
\(ac^2 = 52\)
Taking the square root of both sides, we get:
ac = √52
ac = 2√13 cm

To find bc, we can use the fact that triangle abc ~ triangle ade. This means that the corresponding sides are proportional. So, we can write the following ratio:

bc / ac = ab / ad

From the given information, we know that ab = 3√12 cm and ad = cm = 3√12 cm. Substituting these values into the ratio, we have:

bc / 2√13 = 3√12 / 3√12

Simplifying, we get:

bc / 2√13 = 1

Cross-multiplying, we have:

bc = 2√13

Lastly, to find de, we can use the fact that de is the projection of h on ac. This means that de is the altitude of the triangle ade. Therefore, de is equal to the altitude of the original triangle abc, which is hc = 4 cm.

So, the final results are:
ac = 2√13 cm
bc = 2√13 cm
de = 4 cm
