How do i factor 12b^2+14b-10 using one of the six techniques for factoring polynomials?
Firlakuza [10]

Simplifying

b2 + 12b + 35 = 0

Reorder the terms:

35 + 12b + b2 = 0

Solving

35 + 12b + b2 = 0

Solving for variable 'b'.

Factor a trinomial.

(7 + b)(5 + b) = 0

Subproblem 1

Set the factor '(7 + b)' equal to zero and attempt to solve:

Simplifying

7 + b = 0

Solving

7 + b = 0

Move all terms containing b to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + b = 0 + -7

Combine like terms: 7 + -7 = 0

0 + b = 0 + -7

b = 0 + -7

Combine like terms: 0 + -7 = -7

b = -7

What is 100/7 divided by 4 1/3 simplified if you answer thank you and happy holidays
SVETLANKA909090 [29]

Answer: 300/91

Step-by-step explanation:

1. Convert 4 1/3 to an improper fraction

13/3

2. Divide, using the keep, change, flip method to divide fractions

- Keep the first fraction the same (100/7)

- Change the division sign to a multiplication sign

- Flip the second fraction (13/3 -> 3/13)

3. Plug-in and evaluate

100/7 * 3/13

300/91

If you are looking for the solution as a mixed number, it is 3 27/91

4. Simplify, if applicable. This fraction cannot be simplified any further.

In the most recent election, 19 percent of all eligible college students voted. If a random sample of 20 students were surveyed,
lora16 [44]

Answer:. This would be 0.81^20 for none of the 19=0.0148

Step-by-step explanation:With a tree diagram, there are two possibilities, one is ND from 1 D from 2, with probability (5/8)(2/5)=(1/4) and the other is (3/8)(3/5)=9/40 That would be 19/40 for the answer.

3. Poisson parameter lambda=5

for P(0), it is e^(-5)(5^0)/0! or e^(-5)=0.0067

 

for P(1), it is e^(-5)(5^1)/1! or 5e(-5)

The total probability is 6e^-5 or 0.0404

4. the mean is 1000 hours, so lambda is the reciprocal or 1/1000

the probability it will last <800 hours is 1-e^(-800*1/1000) or 1-e^(-.8)=0.5507

5. assume p=0.4 since it ca't be 4

sd is sqrt (np*(1-p))=sqrt (6*0.6=sqrt(3.6)=1.90
