Answer:
<u>1/6</u>
Step-by-step explanation:
<u>P (red)</u>
- No. of red / Total
- 3 / 3 + 4 + 2
- 3/9
- 1/3
<u>P (green without replacing red)</u>
- No. of green / Total - 1
- 4 / 9 - 1
- 4/8
- 1/2
<u>P (final)</u>
- P (red) × P (green without replacing red)
- 1/3 × 1/2
- <u>1/6</u>
The 'mean' is most affected by adding a really small or large number to a data set. These big or small numbers are called 'outliers' in statistics :)

Answer:
a8 = 512.
Step-by-step explanation:
This is geometric sequence with common ratio r = 2 and first term a1 = 4.
nth term = a1 r^(n-1)
So a8 = 4 2(^8-1)
= 4 * 2^7
= 4*128 = 512.

Answer:
16 cm2
Step-by-step explanation:
By equa tion of area of triangle: S = 1/2 * height * base
Triangle B: 32 = 1/2 * 8 * x --> x = 8 (cm)
The base of triangle A is half of the base of triangle B so it is 4 cm.
The area of triangle A = 1/2 * 8 * 4 = 16 (cm2)
