Answer:
I think I can prove
Step-by-step explanation:
statement. reasons
L1 = L2. corresponding angle,l¹//l²
therefore,L2 = 123°. L1= 123°
L2 + L1 = 180°. t¹//t²
123°+L1 = 180°
L1 = 57°
Determine the mean ,median,modes ,IQR,and rage for the data 3,8,6,6,4,6,9,9,12
Verdich [7]
Mean:
Add all the numbers:
3 + 8 + 6 + 6 +4 + 6 + 9 + 9 + 12 = 63
There are 9 numbers.
63 / 9 = 7
Mean = 7
Median:
Order all the numbers:
3, 4, 6, 6, 6, 8, 9, 9, 12
The median is 6.
Mode:
The number that appears the most is 6.
The mode is 6.
Inter-Quartile Range :
Median of 2nd part = 9
Median of 1st part = 5
Subtract:
9 - 5 = 4
The IQR is 4.
Range:
The highest number is 12. The lowest is 3
Subtract:
12 - 3 = 9
The range is 9.

Answer:
12 eggs
Step-by-step explanation:
If she sends 3/4 to the market
1 - 3/4
4/4 -3/4 = 1/4
She will keep 1/4
1/4 *48 = 12
She will keep 12 eggs

Answer:
Step-by-step explanation:
So we want to simplify:
Note that this is in the format:
And we know that this is the same as:
Let 2√5 be a and let √3 be b. Thus:
Simplify:
And this cannot be simplified any further.
