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.
Subtract 4 from both sides of the equation.
y=-4-2x+2
add -4 and +2.
the answer is
y=-2x-2
Answer:
C
Step-by-step explanation:
Use the circle area formula.
A = pi * r^2
A = pi * 4^2
A = pi * 16
A = 50.27

c = 10 + 3t is a linear function with y-intercept (0, 10) and slope 3.
Plot (0, 10). Starting there, move your pencil point 1 unit to the right and 3 units up. Plot this new point (1, 13). Draw a line connecting
(0, 10) and (1, 13).
