Answer:
The probability the 2 randomly chosen bulbs selected are both red is 0.183
Step-by-step explanation:
No. of red tulip bulbs = 14
No. of yellow tulip bulbs = 9
No. of purple tulip bulbs = 2
Total number of bulbs in a bag = 32
Probability of getting red bulb on first draw =
Now the bulb is not replaced
So, Total bulbs = 32-1 =31
No. of red tulip bulbs = 14-1 = 13
Probability of getting red bulb on second draw =
So,Probability of getting both red bulbs without replacement =
Hence The probability the 2 randomly chosen bulbs selected are both red is 0.183
That's a 240 degree sector of a 9 inch radius circle. The whole circle has area πr² and we want 240/360 of it.
A = (240/360) π (9²) = 54 π
Answer: 54 π square inches
That's the exact answer. An approximation is
169.646 square inches
Answer:
position 1 5 8 12 19 25
term -8 8 20 36 64 88
Step-by-step explanation:
(n - 1) is position ( n ∈ N)
d is the distance between the numbers in the sequence
a1 is the first number in the sequence
we have the fuction: a(n) = a1 + (n - 1)d
see in the table, with position = 1, term = -8 => a1 + d = -8
position = 25, term = 88 => a1 + 25d = 88
=> we have: a1 + d = -8
a1 + 25d = 88
=> a1 = -12
d = 4
=> a(n) = -12 + 4(n - 1)
=> term = 8, position = (8 + 12)/4 = 5
position = 8, term = -12 + 4.8 = 20
term = 36, position = (36 + 12)/4 = 12
position = 19, term = -12 + 4.19 = 64
Answer:
2 and 1/4
Step-by-step explanation:
3.5 - 1.25 = 2.25
2.25 as a mixed number is 2 and 1/4
