83 + 96 + 88 = 267
267 / 3 = 89
(89 + x) / 2 = 90
Multiply both sides by 2.
89 + x = 180
Subtract 180 - 89.
x = 91
Based in your question where as ask on which of the following is the equivalent to x^2/xy^2 when y=0 and z=0 and based on my calculation and understanding the possible outcome of your equation will just result to zero but the answer is i think all of them
The standard deviation is proportional to the scale factor. Cutting each score in half will result in a standard deviation of
σ = 8/2 = 4
Answer:
1. (2.2, -1.35) and (2.2, -1.4)
2. y = 8x - 7
3. infinite number of solutions
4. (2.2,-1.4) (2.2,-1.35)
5. 6
6. (1.33,1)
Step-by-step explanation:
Answer:
k= 60
Step-by-step explanation:
The angles are alternate exterior angles and alternate exterior angles are equal when the lines are parallel.
2k+11 = 131
Subtract 11 from each side
2k+11-11 =131-11
2k =120
Divide by 2
2k/2 =120/2
k = 60
