jeka94

Answer:

Step-by-step explanation:

38.

$M=\frac{1}{2} (x_{1}+x_{2})\\2M=x_{1}+x_{2}\\x_{1}=2M-x_{2}$

37.

$S=\frac{ab^2}{3} \\3S=ab^2\\b^2=\frac{3S}{a} \\b=\pm\sqrt{\frac{3S}{a} }$

Find the probability of rolling a sum of 6 with two dice?

34kurt

Answer: 5/36

Step-by-step explanation:

There are 3 ways to do this

Get a 1 and a 5

Get a 2 and a 4

Or get two 3's.

There are two ways to get a 1 and a 5

1 first and 5 second or

5 first and 1 second

The same goes for the 2 and the 4, but NOT for the two 3s.

We have 5 ways to get a sum of 6

What is the probability of one of them happening?

1/6 x 1/6 = 1/36

1/36 chance of one occuring

1/36 x 5 = 5/36 chance of getting a sum of 6 (as there are 5 ways to do so)

A new computer loses 1/2 of its value every year. Which graph could represent the relationship between the year and the computer

Igoryamba

Let's first consider: the fact that a new computer loses 1/2 of its value

⇒ third choice and fourth choice are eliminated

⇒ because of the graph project the computer's value as growing over

years

Now let's try to set up an equation:

After 1st year ⇒ Computer's value = $total_.value*\frac{1}{2}$

After 2nd year ⇒ Computer's value = $total_.value*\frac{1}{2}*\frac{1}{2}=total_.value*(\frac{1}{2} )^2$

After 3rd year ⇒ Computer's value = $total_.value*\frac{1}{2}*\frac{1}{2}* \frac{1}{2}=total_.value*(\frac{1}{2})^3$

..... (Hopefully you see a pattern)

After x year ⇒ Computer's value = $total_.value*(\frac{1}{2})^x$

Therefore, the equation is: $total_.value*(\frac{1}{2})^x$

⇒that means the graph has to exponentially decreasing as it has

an exponent (meaning the function is exponential) and a base less

than 1 (meaning that the function is decreasing)

Answer: Choice (1)

Hope that helps!
