Answer:
x+y < 28
Step-by-step explanation:
1. Look at your variables: x is the first number and y is the second.
2. Know the limits: It says it has to be NO MORE than 28, so the inequality has to be less than (<) 28. And it says that the SUM of 2 numbers (in this case x and y), is no more than 28, so you know there's some addition between the two.
3. Write out your inequality: x+y < 28
Answer:
Common ratio, r=-3
Recursive Formula
Step-by-step explanation:
The formula for the geometric sequence: 
is given as:
<u>Common Ratio</u>
Dividing the next terms by the previous terms, we obtain:
Therefore, the common ratio of the sequence, r=-3
<u>Recursive Formula</u>
We observe that the next term, 
is obtained by the multiplication of the previous term. f(n-1) by -3.
Therefore, a recursive formula for the sequence is:
C. (22,16)
Y=x-6
16=22-6
16=16
Answer:
2.1
Step-by-step explanation:
Given :
Radios(X):_0 ___ 1 ___2 ___ 3 ___4 ___5
P(X=x) : 0.03 0.20 0.50 0.20 0.05 0.02
The expected weekly radio sales :
Σ(X) * p(x) : (0*0.03) + (1*0.20) + (2*0.50) + (3*0.20) + (4*0.05) + (5* 0.02) = 2.1
Hence, expected weekly radio sale = 2.1
