If 4b-3=2b, then 12b=

1 answer:

6 0

Hi there! The answer is 18.

First we need to solve the first equation for b.
$4b - 3 = 2b$

Subtract 2b from both sides.
$2b - 3 = 0$

Add 3 to both sides.
$2b = 3$

Divide both sides by 2.
$b = \frac{3}{2} = 1 \frac{1}{2}$

Now we can plug our value of b into the second expression.
$12b = 12 \times 1 \frac{1}{2} = 18$

A basketball player has attempted 24 shots and made 17 find the experimental probability round to three decimal places

VashaNatasha [74]

Answer:

0.708

Step-by-step explanation:

A great way to solve for probability is to create a fraction.

In our case, we can see that 17 out of 24 times they made it.

17/24 is our fraction.

Since the viniculum in a fraction represents division, we really have 17 divided by 24.

That is 0.7083.....

Rounding gives 0.708 as our final answer.

What is the recursive rule for the sequence?

Marrrta [24]

The next term is 1.4 larger than the one before it, so the appropriate choice is

$a_{n}=a_{n-1}+1.4 \quad\mbox{where}\ a_{1}=1.4$

_____

However, the description

$a_{n}=a_{n+1}-1.4 \quad\mbox{where}\ a_{1}=1.4$

also correctly describes the relationship between a1 and a2, for example. While this equation is technically correct, it is less useful to work with, so is probably not the expected answer.
