Answer:
the total price of the TV is $840.
Step-by-step explanation:
100% - 30% = 70%
I'm guessing you meant 1,200 not 1.20 (lol) so I'm just going to go with that.
1,200 * 0.70 = 840
Therefore the total price of the TV is $840.
Please mark brainliest and have a nice day!
Multiply both sides by 8 (to undo the division of 8)
x/8 < 10
8(x/8) < 8*10
x < 80
So any number less than 80 will make the original inequality true. This applies to choices: C, D, E which are the final answers. These values are all less than 80.
---------------------------------
Alternatively we can plug in each value into the inequality to check them
Choice A
x/8 < 10
80/8 < 10
10 < 10
false; choice A is eliminated
-------
Choice B
x/8 < 10
96/8 < 10
12 < 10
false; choice B is eliminated
-------
Choice C
x/8 < 10
64/8 < 10
8 < 10
true; choice C is one of the answers
-------
Choice D
x/8 < 10
40/8 < 10
5 < 10
true; D is another one of the answers
-------
Choice E
x/8 < 10
32/8 < 10
4 < 10
true; choice E is another solution
-------
Choice F
x/8 < 10
88/8 < 10
11 < 10
false; choice F is eliminated
---------------------------------
Whichever method you end up using, the final answers are C, D, E
Answer: Table 1: Answer = 1. 404
Table 3 Answer = 1.66
Step-by-step explanation: i hope it's right if not, tell me
4,5,5,5,6 When you add 4+5+5+5+6 it = 25. You then divide it by the amount f numbers which is 5, which = 5. And 5 is the number you see the most. So that is your answer
Answer:
b. 98
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
So a sample of at least 98 is required.
The correct answer is:
b. 98
