Answer:
a) Scores of 2 and higher are significantly high
b) Scores of -2 and lower are significantly low
c) Scores between -2 and 2 are not significant.
Step-by-step explanation:
Mean = 0
Standard deviation = 1
a. significantly high (or at least 2 standard deviations above the mean).
2 standard deviations above the mean is:
0 + 1*2 = 2
So scores of 2 and higher are significantly high
b. significantly low (or at least 2 standard deviations below the mean).
2 standard deviations below the mean is:
0 - 1*2 = -2
So scores of -2 and lower are significantly low
c. not significant (or less than 2 standard deviations away from the mean).
2 standard deviations above the mean is:
0 + 1*2 = 2
2 standard deviations below the mean is:
0 - 1*2 = -2
So scores between -2 and 2 are not significant.

Answer: 20
Step-by-step explanation:
Assuming your question is:
Z² - X² - XY X = -2, Y = 3, Z = -4
Substitute values
(-4)² - (-2)² - {(-2)(3)}
{(-4)(-4)} - {(-2)(-2)} - (-6)
(16) - (4) + 6
16 - 4 + 6

Answer:
Step-by-step explanation:
The orange divisor(s) above are the prime factors of the number 168. If we put all of it together we have the factors 2 x 2 x 2 x 3 x 7 = 168. It can also be written in exponential form as 23 x 31 x 71
This is what the internet says!

Answer:
Step-by-step explanation:
Begin with process of elimination: As seen on the graph, there is a discontinuity at x=3. this means that x>=3. so we can eliminate B and C
Now you can see that at x = 3, two things happen. When moving to the left, x<3. when moving tot he right x>=3 so because of this you can eliminate D. The answer is A
