Answer:
The first step is
Take the square root of both sides of the equation
Step-by-step explanation:
we have

Solve for x
step 1
Take square root both sides

the solutions are
and 
therefore
The first step is
Take the square root of both sides of the equation
Answer:
The condition for r is the following:

And for this case if we analyze the options the only impossible value is given by:
1.0528
Because this value is higher than 1 and not satisfy the general limits for r
Step-by-step explanation:
The correlation coefficient is a measure of dispersion and is a value between -1 and 1, and is defined as:
The condition for r is the following:

And for this case if we analyze the options the only impossible value is given by:
1.0528
Because this value is higher than 1 and not satisfy the general limits for r
He would need 11.1 gallons of gas if he was/would drive 296 miles.
12 divided by 320 = .0375
.0375 x 296 = 11.1 Gallons of Gas needed to drive the distance.
Questions like this ("how much higher is x than y?") are answered by computing the ratio of the two quantities.
In fact, for example, the answer to "how much higher is 10 than 5?" is 2, because 10:5 = 2, and indeed 10 is twice as much as 5.
So, we have

So, the melting temperature of platinum is about one time and a half higher than the melting temperature of gold.
