Answer:
geometric with r =
Step-by-step explanation:
An arithmetic sequence has a common difference (d) between consecutive terms
2 - 4 = - 2
1 - 2 = - 1
Then d is not common , not an arithmetic sequence
A geometric sequence has a common ratio (r ) between consecutive terms
2 ÷ 4 = 0.5
1 ÷ 2 = 0.5
Then common ratio r =
Thus sequence is geometric
We could use the proportion
7/12=?/60
Then do 60×7=420
Then 420/12= 35

Answer:
0.111
Step-by-step explanation:
It is given that a manufacturing company found out that the intrastate contracts having a low bid which are distributed between and of dollars.
Therefore, the probability that a low bid on the shipping contract is in excess of is given by :
P(x ≥ 30) = 1 - P(X ≤ 30)
= 0.111
40/60= 0.67 (i.e. 2/3)= about 66.67%
Answer:
f(-x) = -4x^3 + 9x, f(x) is an odd function
Step-by-step explanation:
We are given that f(x) = 4x^3 - 9x. In order to solve this problem, we first need to understand what an odd function is and what an even function is. When we have an odd function, f(-x) = -f(x). Meaning, that if we plug -x in for x, we should get -f(x). On the other hand, with an even function, f(-x) = f(x). Even if you change the sign, when you simplify, you will get back the same function. In either case, we have to first find f(-x) to figure this problem out:
We can see from our answer for f(-x) that it is equal to -f(x). We can verify this below:
Since f(-x) = -f(x), our function f(x) is an odd function
