Answer:
The common difference is -1.4
Step-by-step explanation:
The common difference is found by taking 2nd term and subtracting the first term
7.3-8.7 = -1.4
Lets check by taking the 3rd term and subtracting the 2nd term
5.9-7.3 = -1.4
The common difference is -1.4
Answer:
The factored form is (3+ x^2)(5 + 2x)
Step-by-step explanation:
I.I rewrited it as 15 + 5x^2 + 6x + 2x^2
= 5(3 + x^2) + 2x(3 + x^2)
= 
II. Prove by
= 3(5) + 3(2x) + x^2(5) + x^2(2x)
= 15 + 6x + 5x^2 + 2x^3
That makes = 2x^3 + 5x^2 + 6x + 15

Answer:
The required probability is
or
.
Step-by-step explanation:
Consider the provided information.
A committee of 9 members is voting on a proposal. Each member casts a yea or nay vote. On a random voting basis,
The probability of yea or nay vote is equal, = 
So, we can say that 
Use the formula: 
Where n is the total number of trials, x is the number of successes, p is the probability of getting a success and q is the probability of failure.
We want proposal wins by a vote of 7 to 2, that means the value of x is 7.
Substitute the respective values in the above formula.





or 
Hence, the required probability is
or
.
