Evaluate the expression for the given value of the variable(s). 5a+5b;a=-6b=-5
A. 19 B. 17 C. -11 D. 21
Answers
The given expression is 5a+5b The given values of a and b are a=-6 ,b=-5
Substituting the values of a and b in the expression we have :
5a+5b= 5(-6)+5(-5)
= -30 -25 ( when a positive and a negative number is multiplied the result is a negative number)
-30-25=-55 (same signs are added)
The answer to the expression 5a+5b when a=-6 anf b=5 is -55.

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
