Answer:
1. A 2. B
Step-by-step explanation:
1. 9(6 times x) and 9 x 6 + 9 times x
Thhis is correct because you do the same for both
2. 1 pound is 16 ounces. So 12.5 x 16 = 200
Answer: y= -1/1x - 1
Okay, to find the equation you must find the y-intercept and the slope.
To find the y-intercept, you must find (0,y). This is the point on the y-axis where x is 0. So, where along the y-axis is there a point? There is a point at (0,-1). Therefore, your y-intercept is -1.
To find the slope, you must do rise/run. Go to a point on the line, such as (0,-1). You must go up (or down) until you get lined up with next point on the line. You go up one time. Then, you must go right (or left) to get to the exact point. In this case, the point would be (-1,0). You go left one time.
If you go down or left when doing rise/run, the number would be negative. Since you went left, that number would be negative.
So, our slope would be 1/-1, which can also be written as -1/1.
Now, write the equation. There is always an x next to the slope. y= -1/1x
Then, put the y-intercept next to it. If it is positive, use a +. If it is negative, use a -. It is negative.
Therefore, the answer is y= -1/1x -1.

Answer:
By definition since in a continuous probability distribution the area below a line is 0
If the real question is:
We can use the z score formula given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard table or excel:
And if the question is we apply the complement rule and we got:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the strengths of a population, and for this case we know the distribution for X is given by:
Where and
For this case we want
And by definition since in a continuous probability distribution the area below a line is 0
If the real question is:
We can use the z score formula given by:
If we apply this formula to our probability we got this:
