Answer:
Z-score = -1.285
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 17.6 seconds
Standard Deviation, σ = 2.1 seconds
Formula:
For x = 14.9, we have:
A z-score to be unusual if its z-score is less than -2.00 or greater than 2.00.
Thus, the z-score is not unusual as it lies in the range [-2.00, 2.00]

In the same way as you could factor trinomials on the form of
<span><span><span>x2</span>+bx+c</span><span><span>x2</span>+bx+c</span></span>
You can factor polynomials on the form of
<span><span>a<span>x2</span>+bx+c</span><span>a<span>x2</span>+bx+c</span></span>
If a is positive then you just proceed in the same way as you did previously except now
<span><span>a<span>x2</span>+bx+c=<span>(<span>x+m</span>)</span><span>(<span>ax+n</span>)</span></span><span>a<span>x2</span>+bx+c=<span>(<span>x+m</span>)</span><span>(<span>ax+n</span>)</span></span></span>
<span><span>where c=mn,ac=pq </span><span>and b=p+q=am+<span>n</span></span></span>

answer is A $435.20
Step-by-step explanation:
I guess I was help full for u
plz follow me for more updates
In the point (x, y), if x=0, then the point is on the y axis.
If y=0, the point is on the x axis
If both x and y are positive (greater than 0), the point is in quadrant 1
If x is negative (less than 0) and y is positive (greater than 0), the point is in quadrant 2
If both x and y are negative, the point is in quadrant 3
If x is positive and y is negative, the point is in quadrant 4
Taking (-3, 2), since 3 has a - sign before it (and nothing else), it is negative. Since the x value comes first, this means that x is negative. Since it simply states "2" for the y value, it is positive. As x is negative and y is positive, we know that the point is in quadrant 2.
I challenge you to do this on your own - good luck, and feel free to ask with further questions!
