Answer:
Step-by-step explanation:
First term (a) = 7
common difference (d) = 10- 7 = 3
Now
General term
tn = a + (n - 1)d
= 7 + ( n - 1)3
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
.

Answer is -8</h3>
Work Shown:
y = -(2^x)
y = -(2^3) ... replace x with 3
y = -(2*2*2) ... expand out 2 cubed
y = -8
Question:
7x - 11 - 4x = 6
1. Simplify,
3x - 11 = 6
2. Add 11 to both sides
3x - 11 + 11 = 6 + 11
3x = 17
3. Divide 3 from both sides
3x/3 = 17/3
x = 17/3 <===== <em>Answer</em>
Hope this helped!!!
