We can calculate the speed to be
.. (36 mi)(0.75 h) = 48 mi/h
or we can just assume that is what it is based on the fact that 48 is the only number in any of the offered answers.

distance = speed * time
.. y = 48 * x . . . . . . . . . . . . . . . . corresponds to selection A

_____
There is no question 17.

_____
15. All sections of the graph are linear. All sections except Q show the function increasing (left to right, which is how we talk about it). Thus selection B is the only sensible one.

The area of a rectangle is (x3 – 5x2 + 3x – 15), and the width of the rectangle is (x2 + 3). If area = length × width, what is t

lisabon 2012 [21]

Answer:

Step-by-step explanation:

The area of a rectangle is given by the formula:

$A=lw$

So, we are given that the area is:

$x^3-5x^2+3x-15$

And the width is:

$x^2+3$

And we want to find the length. To do so, first substitute the expressions into the equation:

$x^3-5x^2+3x-15=(x^2+3)l$

Thus, to find the length, divide by (x²+3):

$l=\frac{x^3-5x^2+3x-15}{x^2+3}$

So, factor the numerator:

$x^3-5x^2+3x-15$

From the first two terms, factor out a x^2.

From the third and fourth terms, factor out a 3:

$=x^2(x-5)+3(x-5)$

Combine:

$=(x^2+3)(x-5)$

Putting this back:

$l=\frac{(x^2+3)(x-5)}{x^2+3}$

Cancel:

$l=x-5$

And that's our answer :)

I believe it would be D.

The chance that a person is left handed is 0.15 or 15%. if you randomly select 8 people, what is the probability that they are a

Wittaler [7]

Answer: The probability that all 8 people are right handed is about 27.25%.

If the chance a person is left handed, the chance a person is right handed is 85%.

Now, we just need to find the chance that this 85% event happens 8 times in a row.

Simply, multiply it by itself 8 times.

(0.85)^8 = 0.2725

There is a 27.25% chance all 8 people are right handed.
