Answer:
3 coefficients in this expression are: -2x, 5y and 9 (natural number)
Step-by-step explanation:
-6x + 5y + 4x + 9
= -6x + 4x + 5y + 9
= -2x + 5y + 9
3 coefficients in this expression are: -2x, 5y and 9 (natural number)
Hope this help you :3
The square root of 72 is rational because the answer can be a real number.
Hi!
So for this problem, we're given the y-coordinate and we can plug that in for y in the equation. So let's do that
-1 = -3/5x - 7
6 = -3/5x
30 = -3x
-10 = x
The missing coordinate would be x, assuming that the equation was y = (-3/5)x - 7
Answer:
The correct option is (b).
Step-by-step explanation:
If X 
N (µ, σ²), then 
, is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is, Z N (0, 1).
The distribution of these z-variate is known as the standard normal distribution.
The mean and standard deviation of the active minutes of students is:
<em>μ</em> = 60 minutes
<em>σ </em> = 12 minutes
Compute the <em>z</em>-score for the student being active 48 minutes as follows:
Thus, the <em>z</em>-score for the student being active 48 minutes is -1.0.
The correct option is (b).
Answer:
<u><em>X=1</em></u>
