Answer:
The sum of the first 650 terms of the given arithmetic sequence is 2,322,775
Step-by-step explanation:
The first term here is 4
while the nth term would be ai = a(i-1) + 11
Kindly note that i and 1 are subscript of a
Mathematically, the sum of n terms of an arithmetic sequence can be calculated using the formula
Sn = n/2[2a + (n-1)d)
Here, our n is 650, a is 4, d is the difference between two successive terms which is 11.
Plugging these values, we have
Sn = (650/2) (2(4) + (650-1)11)
Sn = 325(8 + 7,139)
Sn = 325(7,147)
Sn = 2,322,775
B is the right answer for you question
Answer:
1% of 300 is 3 so if you multiply that 3 by 64, you get 192 which is also 64% of 300
Step-by-step explanation:
.01 x 300 = 3
3 x 64 = 192
.64 x 300 = 192
3/5 flowers are red
So, 3/5 = 0.6 which is 60%
Therefore, there is a 60% chance a red flower will be picked
