Answer:
10
Step-by-step explanation:
We are going to substitute x = 3 - i into the expression x² - 6x
* Remember than i² = (√-1)² = -1. so when we multiply and get i² we're going to transform it into -1.*
⇒
Thus, x² - 6x = 10 when x = 3-i

1. Simplify:
-2(n + 3) = 13
-2n - 6 = 13
2. Change „-6” side to right (to get answer), without forgetting to change the sign:
-2n - 6 = 13
-2n = 13 + 6
-2n = 19
3. Simplify (The „|” means operation done at both sides of equation):
-2n = 19 |:(-2)
n = -9.5
Proof:
-2(-9.5 + 3) = -2 * (-6.5) = 13

What is the experimental probability of rolling the given result?

b.

d.

Final answer:
The experimental probability of rolling the given results are: a. 0.16, b. 0.18, c. 0.22, d. 0.1. The correct answer is b. 0.18.
Explanation:
To find the experimental probability of rolling a given result, divide the frequency of that result by the total number of rolls. In this case, the frequency of rolling a 1 is 32, and the total number of rolls is 200. So the experimental probability of rolling a 1 is 32/200 = 0.16. Repeat this process for the other results:
- Experimental probability of rolling a 2: 36/200 = 0.18
- Experimental probability of rolling a 3: 44/200 = 0.22
- Experimental probability of rolling a 4: 20/200 = 0.1
- Experimental probability of rolling a 5: 30/200 = 0.15
- Experimental probability of rolling a 6: 38/200 = 0.19
Based on these calculations, the experimental probability of rolling the given results are:
- a. 0.16
- b. 0.18
- c. 0.22
- d. 0.1
Therefore, the correct answer is b. 0.18.

Answer: D) 0.44
==========================================================
Explanation:
Add up all the frequencies that correspond to outcomes that are more than 3
So we'll add up the last three frequencies (since they correspond to outcomes of 4, 5 and 6 all of which are greater than 3) to get 20+30+38 = 88
We have 88 occurrences of rolling either a 4, a 5 or a 6. This is out of 200 rolls total.
The empirical (or experimental) probability of getting more than 3 on the die is 88/200 = 0.44
