A _____ is a function that assigns a numerical value to every possible outcome in a sample space.

Answers

The answer is:
 
 A Ramdom variable is a function that assigns a numerical value to every possible outcome in a sample space.
 
 It is a number that represents a result of an event or a random experiment. This variable does not depend on other factors and its values ​​are random, without a specific order. For example: when you roll a dice, the number that you get is a random variable, because in 6 attempts you may get 1,6,4,2,2,5 and then, in another 6 attempts, you may get 3,3, 6,2,1,6.

Given two vectors a⃗ = 4.60 i^+ 7.20 j^ and b⃗ = 5.10 i^− 2.70 j^ , find the scalar product of the two vectors a⃗ and b⃗ .

Answers

a=<4.60,7.20>
b=<5.10,2.70>
The scalar product, or the inner product, or the dot-product, is by summing the products of the respective directions, 
a.b=4.6*5.1+7.2*2.7
=23.46+19.44
=42.9

In this exercise we have to use the knowledge of vectors to find the dot product between them, in this way we can say that:

[tex]|a|*|b|=42.9[/tex]

Knowing that it was stated by the text that the vectors have the value of :

[tex]a=<4.60,7.20>\\ b=<5.10,2.70> [/tex]

The scalar product, or the inner product, or the dot-product, is by summing the products of the respective directions, will be:

[tex]|a|*|b|=4.6*5.1+7.2*2.7\\ =23.46+19.44\\ =42.9 [/tex]

Tom was saving $3000 for a trip. He initially deposited $200 in a savings account and then deposited a fixed amount every month in the account for the next 5 months. Then he received a check in the mail. The check was three times as much as the total amount he had saved so far. When he deposited the check in his savings account, he had $200 more than he needed. What was the fixed amount he deposited in the savings account during the 5 months?

Answers

The answer is $120. To determine this, you will represent the situation as an equation:

4(200 + 5x) = 3200. I came up with this because it says he started with 200 and added a fixed amount every month for 5 months (5x). If the check was 3 times the amount he already had saved, then he has 4 times what he started with.

His goal was $3000, but he has $200 more than that, so $3200 would be the amount he has.

I have attached the work showing how to solve for x, the amount he depositors each month.

Answers

First we are going to express both equation in terms of  [tex]y[/tex] to compare their slopes:
For our first equation:
[tex]-x=1-y[/tex]
[tex]-x-1=-y[/tex]
[tex]y=x+1[/tex]
For our second equation:
[tex]-1+y=x+2[/tex]
[tex]y=x+3[/tex]
So now we have our system of equations in terms of y:
[tex] \left \{ {{y=x+1} \atop {y=x+3}} \right. [/tex]
Notice that the slope, the coefficient of [tex]x[/tex], in both equations is the same: 1, and if tow linear equations have the same slope, they are parallel.

We can conclude that we can classify the system of equations as parallel.

List 3 values that would make this inequality true 43 < y -30

Answers

43 < y - 30
add 30 to both sides
73 < y

y can be anything that is greater than 73
so it could be...
101, 74, 90, 75, 980767, 5674, etc.

Hope this helps!

Final answer:

To make the inequality 43 < y - 30 true, add 30 to both sides to get 73 < y. Any number greater than 73, such as 74, 80, or 90, will satisfy the inequality.

Explanation:

To find values that make the inequality 43 < y - 30 true, you simply need to add 30 to both sides of the inequality. This gives you:

73 < y

This means that any value greater than 73 will make the inequality true. Here are three examples:

y = 74 (since 74 is greater than 73)y = 80 (since 80 is greater than 73)y = 90 (since 90 is greater than 73)

You can choose any three numbers greater than 73, and they will satisfy the inequality 43 < y - 30.

Ron is taking an inventory at his store. Based on previous sales, he predicted sales of 25 folders and 230 erasers. He actually sold 30 folders and 200 erasers. What is the percent error for the erasers?

Answers

Answer: There is 15% error for the erasers

Step-by-step explanation:

Since we have given that

Number of folders he predicted = 25

Number of erasers he predicted = 230

Total number of inventories he predicted is given by

[tex]230+25=255[/tex]

Number of erasers he actually sold = 200

Number of folders he actually sold = 30

Total number of inventories he actually sold is given by

[tex]200+30=230[/tex]

Error in estimation is given by

[tex]230-200=30[/tex]

Percentage of error for the erasers only  

[tex]\frac{30}{200}\times 100\\\\=\frac{30}{2}\\\\=15\%[/tex]

Hence, there is 15% error for the erasers.

Answer:

15 %

HELP 50 POINTS! What are the key features needed to graph a polynomial function? Explain how to find these key features to sketch a rough graph of a polynomial function.

Answers

Lines and plots because you need to form a shape

The explanation can be given down in details . Using this information

are the key features needed to graph a polynomial function and to find these key features to sketch a rough graph of a polynomial function.

To graph a polynomial function, you need to identify and understand its key features, which include:

Degree: The highest power of the variable in the polynomial determines its degree. For example, a polynomial of degree 3 would have terms like [tex]ax^{3} +bx^{2} +cx+d.[/tex] The degree influences the behavior of the polynomial, such as whether its ends point up or down.

Leading Coefficient: The coefficient of the term with the highest power of the variable. It influences the end behavior of the polynomial, determining whether the graph rises to the left and rises to the right or falls to the left and falls to the right.

Roots (Zeros): These are the values of [tex]x[/tex] for which the polynomial evaluates to zero. They are the points where the graph crosses the [tex]x[/tex]-axis.

Turning Points: Points where the graph changes direction. These occur at local maxima or minima and can be found by setting the derivative of the polynomial equal to zero and solving for [tex]x[/tex].

To sketch a rough graph of a polynomial function, follow these steps:

Determine the Degree and Leading Coefficient: Identify the highest power of the variable and the coefficient of that term.

Find the Roots (Zeros): Set the polynomial equal to zero and solve for

[tex]x[/tex]. These are the points where the graph intersects the x-axis.

Identify Turning Points: Find the critical points by taking the derivative of the polynomial, setting it equal to zero, and solving for

[tex]x[/tex]. Then, use the second derivative test or analyze the behavior of the function around these points to determine whether they are local maxima or minima.

Plot Key Points: Use the roots and turning points to plot key points on the graph.

Consider End Behavior: Determine whether the leading coefficient is positive or negative. If it's positive, the ends of the graph will point upwards; if it's negative, they will point downwards.

Sketch the Curve: Connect the plotted points smoothly, taking into account the behavior of the polynomial between the key points. Make sure to show any symmetry if present and adjust the curvature based on the behavior around turning points.

Optional: Use a Graphing Tool: If available, utilize graphing software or calculators to verify your sketch and refine it if necessary.

By following these steps, you can sketch a rough graph of a polynomial function and visualize its key features effectively.

53 is 100% of the price. If you remove 25% of the price you have 100%-25%=75%. so you multiply 53 by 75% or .75 therefore: 53*.75=$39.75
