Answer:
Step-by-step explanation:
Use the formula to find the z-score, then go to the table that will give you the probability that the value is less than this z-score.

The probability that the value lies to the left of 1 on a standard bell curve is 84.1345%, or 84%, the third choice down.
Answer:
15) Quadratic Function : The 3x is squared
16) Linear Function : It is a straight line
17) Quadratic Function : The line is a U shape
18) Linear Function : There is one y value for every x value, and the points form a straight line

Answer:

Step-by-step explanation:
Okay, to do this we must understand what parallel means.
parallel means that that one line will NEVER touch the other. In order for this to happen they must be increasing (or decreasing) by the SAME rate. I.e the slope of your line must be the same as the lin in question thus our equation looks like,
.
Now lets find
.
To do this, plug the point (3,6) into the equation
6=4(3)+C
6=12+C
-6=C
Thus now that we know C, our equaiton is

<em>Answer:</em>
<em>n = 1067</em>
<em>Step-by-step explanation:</em>
<em />
<em>Since nothing is known, we would assume that 50% of the computers use the new operating system.
</em>
<em>So, standard error = 0.5/SQRT(n)
</em>
<em>Z-value for a 95% CI = 1.9596
</em>
<em>So, margin of error = 1.9596 x 0.5 / SQRT(n) = 0.03
</em>
<em>So, n = 1067 (approx.)</em>
<em />
<em>This will be your approximate answer : n = 1067</em>
