Answer:
By the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 190
Standard deviation = 14
Using the empirical rule, what percentage of the games that Aubree bowls does she score between 148 and 232?
148 = 190 - 3*14
So 148 is 3 standard deviations below the mean.
232 = 190 + 3*14
So 232 is 3 standard deviations above the mean
By the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232
Answer:
<h2>D. The two functions have opposite output values of each other for any given input value.</h2>
Step-by-step explanation:
The reflect function will have opposite output values than the original one, because reflection across the x-axis means that y-values will be with the opposite sign. All positive y-values in the original function will have negative values in the reflected one, and all negative y-values in the original will have positive values in the reflected.
The opposite values are just seen in the output, because those belong to y-axis, all x-axis values remain the same, which are input values. You can see this in the image attached, look for the horizontal reflection. That mirror effect across the x-axis is because the y-values are opposite.
I feel you, headaches suck.

Answer:
3000 bags
Step-by-step explanation:
In this case we must apply the formula of the mean, which would be the sum of the values divided by the amount of data is the mean:
m = (a1 + a2 ... an) / n
In this case we know the mean, we must know the 1987 data, therefore:
Let x be the number of bags sold in 1987, replacing in the previous equation:
2100 = (1800 + 1500 + x) / 3
2100 * 3 = 3300 + x
x = 6300 - 3300
x = 3000
Therefore, for the average to be a total of 2100 bags in those 3 years, the amount of bag sold in 1987 must have been 3000 bags
