Answer: 20inch
Step-by-step explanation:
Using the Pythagoras theorem:-
25^2 = 15^2 + x^2 where x = the width of the screen.
625 = 225 + x^2
x = √(625 - 225) = √400
= = 20 ins
Answer:
A) Mean = 1.0295
Median = 1.006
B) the largest sample Observation can be reduced to 1.3735
Step-by-step explanation:
A) I) The mean Value is the addition of all the values, then dividing by the number of values occured.
0.736 + 0.863 + 0.865 + 0.913 + 0.915 + 0.937 + 0.983 + 1.001 + 1.011 + 1.064 + 1.109 + 1.132 + 1.140 + 1.153 + 1.253 + 1.397 = 16.472
16.472 ÷ 16 = 1.0295
1.0295 is the mean value
II) The median value is the value at the center of the point. We have two values at the middle point.
(1.001 + 1.011) ÷ 2 = 1.006
1.006 is the median value.
Therefore the mean value which shows the actual middle value of the numbers if the numbers where evenly distributed is greater than the median value which show middle value of the numbers in the result.
The difference between them is
1.0295 - 1.006 = 0.0235
B) The largest sample Observation is 1.397. it can be decrease by subtracting the difference between the mean and median from the number.
Wherefore; the difference between mean and median is 0.0235
Therefore;
1.397 - 0.0235 = 1.3735
If the largest sample Observation is reduced to 1.3735, the median value will not be affected.
Well if it was 8 hours in the morning and 7 in the evening per day of the week it would be 105 divided by 2 for the number of sessions would equal to 52.5 sessions. if it was just that amount of time from that whole week, it would be 15 hours divided by 2 which would give you 7.5... Did that help?
The third option is correct
$3.50
702/18= 39 (so you have 39 boxes of cookies)
$136.50/39= $3.50 (so each box cost 3.5)
3.5 x 39= 136.5
