The answer is C. 7
1.) take 8-(-3)
2.) 9-2
3.) 8-0
Then list the number in order least to greatest
-13 7 8
Find the middle number
Get 7
Answer:
2 days
Step-by-step explanation:
Use the given formula
y = 5x + 4
The information:
y is the money spent
x is the number of days
It is known that Justin spent $18
so now just substitute in that value
$18 = 5x + 4
and simplfiy by inverse operations
18 = 5x + 4
-4 -4
14 = 5x
/5 /5
2.8 = x
As per this problem, one can infer that renting a game is done by days, and will be charged in days, hence renting a game for 0.8 days is pointless
meaning that the final answer is 2 full days
1) The formula used for determining the confidence interval is
Sample mean +/- Critical value (or z-score corresponding to 90% confidence) * Standard
error of mean
8439 +/- 1.645 * 100/sqrt 25
8439 +/- 1.645 * 20
8439 +/- 32.9
2) The only difference in this case is finding the critical value i.e., z-score corresponding to 92% confidence which is 1.75 approximately
Then the confidence interval is
8439 +/- 1.75 * 100/sqrt 25
8439 +/- 1.75 * 20
8439 +/- 35
Lower limit is 8439 - 35 = 8404
The upper limit is 8439 + 35 = 8474
Step-by-step explanation:
A reference point is a place or object used for comparison to determine if something is in motion.
