Can you please help me with this question with the steps? 8a^3 -2a^2+ 12a-3

1 answer:

6 0

I'm assuming you want to simplify the expression since it's not equal to anything.. you can't solve for "a" unless it's equal to something.

factor

8a³ - 2a²+ 12a - 3

2a²(4a - 1) + 3(4a -1)

(4a - 1) is a like term that can be combined further.

(2a² + 3)(4a - 1)

Among 400 randomly selected drivers in the 16 minus 18 age bracket, 293 were in a car crash in the last year. If a driver in th

professor190 [17]

Answer:

The approximate probability is 0.7325.

Is not unlikely that a driver in that age bracket is involved in a car crash during a year, so there are reasons to be concerned.

Step-by-step explanation:

The approximate probability can be estimated using the sample proportion:

$p=\dfrac{X}{n}=\dfrac{293}{400}=0.7325$

A probability of 0.7325 is high, so it is not unlikely that a driver in that age bracket is involved in a car crash during a year.

As this value is high, there is reasons to be concerned about it.

To solve this you need to take the answer from the previous iteration.

Iteration 1: The answer is given
a1 = 300

Iteration 2: Solve using the equation. a(n-1) is the answer from the previous iteration. n = the number of the current iteration. So, a(n-1) = 300 and n = 2

a2 = 300/2 = 150

Iteration 3: a(n-1) = 150 and n = 3
a3 = 150/3 = 50

Iteration 4: a(n-1) = 50 and n = 4
a4 = 50/4 = 12.5

Answer: 12.5
