Part A:

Part B:

Step-by-step explanation:
The total number of candies is 40.
10 + 14 + 4 + 12 = 40
14 are Butterfinger and 12 are Crunch.
14 + 12 = 26



40 - 1 = 39

Answer:
Step-by-step explanation:
<u>Sum of (7x+4) and the opposite of 7x:</u>
- 7x + 4 + (-7x) =
- 7x + 4 - 7x =
- 4
Answer:

And for this case we know this condition:

By the complement rule we know that:

But since the distribution is symmetrical we know that:

So then the statement for this case is FALSE.
b. False
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
For this case if we define the random variable of interest X and we know that this random variable follows a normal distribution:

And for this case we know this condition:

By the complement rule we know that:

But since the distribution is symmetrical we know that:

So then the statement for this case is FALSE.
b. False
