Answer:
Your lowest point should be 26, and highest at 56, since that's your min and max value. Your median should be 40. Your Q1 should be 29, and Q2 should be 47.5
Answer:
-x2 + 2x + 8
Step-by-step explanation:
Your first step will be to set up the problem:
f(x) - g(x)
Next, you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly, put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8
The probabilities of each number are equal. Then statements A and C are correct.
<h3>What is probability?</h3>
Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
Given
Pedro has a spinner with 4 sections numbered 1 through 4.
Pedro spins the spinner 100 times and records the results.
He calculates the relative frequency of each outcome.
Outcome 1 2 3 4
Relative Frequency 0.24 0.25 0.26 0.25
A) A uniform probability model is a good model to represent probabilities related to the numbers generated in Pedro's experiment. This statement is correct.
B) The theoretical probability that any one number is chosen is likely 0.20. This is incorrect because every number has an equal probability.
C) It is likely that the spinner is fair. This statement is correct because the probabilities of each number are equal.
D) The relative frequencies in the table are very different. This statement is incorrect. Because numbers 2 and 4 have the same frequency and the number 1 and 3 have slightly different frequencies.

Answer:
C. Multiply the bottom equation by 2
Step-by-step explanation:
-2x+ 4y= 10
3x- 2y =-7
We want to multiply the second equation by 2
-2x+ 4y= 10
6x- 4y =-14
------------------
4x +0y = -4
In order to solve this equation, isolate the variable to find its value
X is 2
