The parentheses must be placed here 48 - (5 + 2) * 3 + 6 in order for the equation to equal 33.
Part A)
His sample only involves days during the summer (if Devin is in the northern hemisphere), which would mean that the high temperatures he'll record are likely to be higher than the average. Therefore, the sample mean he computes does not represent the average high temperature for the whole year.

Answer:
The frequency table is attached below.
Step-by-step explanation:
Given the total number of candies in the box = 18
Frequency table is used to list the occurence of a thing or product and it helps to calculate and sort down easily.
<u>Contains caramel</u> <u>Do not contain caramel</u> Total
<u>Contains chocolate</u> 10 2 12
<u>Do not contain </u> 3 3 6
<u>chocolate</u>
Total number of candies as per the frequency tablr = 12 + 6 = 18 which tallies with the given data.
I’m pretty sure that the answer is 334333
