Answer: to replace all of the drumsticks it would cost $24
Step-by-step explanation:
Answer:
4 x 2 =8 * $3 =$24
She has 8 drumsticks since she has 4 drum kits and each kit has 2 drum sticks you would do 4 x 2 which equals 8.
Since there are 8 drum sticks and each drum stick costs 3$ you would do 8 x3 which would sum up to 24.

Answer:
Probability (P) (k successes out of n trials) = nCk * p^k * (1-p)^(n-k), where nCk = n! / (k! * (n-k)!)
for this problem n=20, p = 1/6(probability of rolling 1 two) is approximately 0.1667
P ( of getting more that 3 two's) = 1 -P(0 two's out of 20 trials) -P(1 two out of 20 trials) -P(2 two's out of 20 trials) -P(3 two's out of 20 trials)
P ( of getting more that 3 two's) = 1 -0.026 -0.104 -0.198 -0.238 = 0.434
My answer is A
Answer:
The sum of the first twenty-seven terms is 1,188
Step-by-step explanation:
we know that
The formula of the sum in arithmetic sequence is equal to
where
n is the number of terms
a1 is the first term
d is the common difference (constant)
step 1
Find the common difference d
we have
n=7
a1=-8
S=28
substitute and solve for d
step 2
Find the sum of the first twenty-seven terms
we have
n=27
a1=-8
d=4
substitute
