Missing Part:
a. A red ball is drawn
b. A white ball is drawn
Answer:
a.
b. 
Step-by-step explanation:
Given



First, we need to calculate the total



Solving (a): Probability of Red.
This is calculated by dividing number of red balls by the total
So:



Solving (a): Probability of White.
This is calculated by dividing number of white balls by the total
So:



Y is less than or equal to 4, y is less than or equal to 14, x is less than or equal to 10, x is less than or equal to 20
When we say a statistic is resistant, we mean the extreme values do not affect the statistic to a large extent or to an extent which makes a major difference. Mean and median are example of such statistics. By changing the extreme values we do not see a substantial difference in the value of mean and median for the data set.
Consider a sample: 1,2,3,4,4,5,6,7,8
The median for this data set is 4.
If we change the extreme values to get this sample: -5,2,3,4,4,5,6,7,100
The median will still be the same i.e. 4. This is what is meant by a resistant statistic.
So option a is the correct ans.
Assuming we are rounding to the nearest 100, five numbers that could be rounded up to 600 are:
550, 567, 579, 580, 599
And five numbers that could be rounded down to 600 are:
601, 610, 625, 630, 649
Answer:
bottom: 12 x 12 = 144
1st triangle: (12 x 8)/2 = 48
2nd triangle: 48
3rd triangle: 48
4th triangle: 48
144 + 48 + 48 + 48 + 48 = <u>336 cm squared</u>
