Answer:
45
Step-by-step explanation:
Both angles have the same value, therefore, you can set your formula up as
5x-105=2x+30
5x = 2x + 30 + 105
5x - 2x = 135
3x = 135
x = 135/3
x = 45
Answer: Third option
Step-by-step explanation:
We have the vector u and the vector v. We must perform the operation .
To perform this operation multiply the vector u by -1 and multiply the vector v by -1.
If u = (-5,6)
So
-1u = (5, -6)
If v = (7, -3)
So
-1v = (-7, 3)
Then the sum of both vectors is done by adding the components of u with the components of v.
I think that the correct answer to this question is E.) 90 .

Answer:
Probability =0.8854 (Approx)
Step-by-step explanation:
Given:
Mean μ = 100
Standard deviation σ = 15
Computation:
Z at 70
Z = (70-100)/15
Z at 70 = -2
Z at 120
Z = (120-100)/15
Z at 100 = 1.33
Probability = φ(1.33) - φ(-2.0)
Probability = 0.9082-0.0228
Probability = 0.8854 (Approx)
