Answer:
= 2n + 6
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = 2 , then
= 8 + 2(n - 1) = 8 + 2n - 2 = 2n + 6
Answer:
6 blue marbles
Step-by-step explanation:
Given;
Total number of marbles N = 15
probability of randomly selecting a green marble
P(G) = 1/5
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble P(G∩B) = 2/25
P(G∩B) = P(G) × P(B)
P(B) = P(G∩B) ÷ P(G)
The probability of selecting a blue marble
P(B) = 2/25 ÷ 1/5 = 2/5
The number of blue marbles N(B) = P(B) × N
N(B) = 2/5 × 15 = 6
There are 6 blue marbles
Ok so first we need to write a fraction.
75 percent/45 mins
then we convert that into a unit rate
1.67 percent/1 min
so, now that we have the unit rate, we know exactly how fast she is moving.
Now, we divide 25 by 1.67 because 25% is the distance between the completion of the gate and current state of the gate.
So we get 14.97, which we can safely round up to 15.
It will take her 15 mins more to finish the gate, and it has already taken 45, so 45+15=60
60 MINS TOTAL/ 1 HOUR
Median: (9+11)/2=10
mean: (2+5+9+11+17+19)/6=63/6=10.5
Those are your answer.
Answer:
Step-by-step explanation:
d = 2r => r = d/2 = 16in/2 = 8 inches
V = Ab×h
= π·r²×h
= 3.14·(8in)²×5in
= 1004.8 in³
