Answer:
a=4m
b=63x¹2 - 35x6 maybe you formatted/typed this wrong, but this is impossible..?
c=4
Given:
Number of spheres = 2
Number of prisms = 3
Number of pyramids = 5
To find:
The probability that a pyramid will be selected.
Solution:
We have,
Favorable outcomes = Number of pyramids
= 5
Total outcomes = Total number of figures
=
=
Now, the required probability is:
Therefore, the probability that a pyramid will be selected is 0.5.
Answer:
3n^2
Step-by-step explanation:
3, 12, 27, 48, 75
List the differences between terms:-
9, 15, 21, 27
Now find the second differences:-
6, 6, 6
The sequence in the question is quadratic and the first coefficient ( that of n^2) = 6/2 = 3. The first term in the nth term formula is 3n^2.
Now we write out the original sequence and the 3n^2 values as follows:-
3 12 27 48 75
3 12 27 48 75
They are the same so the formula for the nth term is 3n^2.
A = P(1+i/n)^nt
A = Total amount paid
P = Principal amount
i = Annual interest
n = number of payments per year
t = time in years
Substituting the values given,
A = 1800(1+0.032/52)^52*10 = $2,478.59
Interest paid = A - P = 2478.59-1800 = $678.59
Second answer is correct.
