Answer:
They are perpendicular.
Step-by-step explanation:
When we convert the equation 6x-2y=-5 into y=mx+b form, it changes into y=3x-5/2. Since we know that perpendicular slopes are opposite reciprocal, the opposite reciprocal of -x/3 is 3. So, we know that these 2 slopes are perpendicular.
Answer: cot 0 = 3
Cotangent is the reciprocal of tangent, so it would be 3/1, which simplified to 3.
Answer:
-122.5
Step-by-step explanation:
Difference = 7 - 4 = 3 terms; 8.75 - (-70) = 78.75
1 term → 78.75/3 = 26.25
therefore, u2 = - 70 - 2(26.25) = -122.5

Answer:
3.6%
Step-by-step explanation:
Because the two events are independent, their probabilities are multiplied, so the probability of a student being born in March and having a blood type of O+ is 9% * 40% = 0.09 * 0.40 = 0.036 = 3.6%
Answer:
d. n = 12
Step-by-step explanation:
n/33 = 4/11
cross-multiply:
11n = 132
divide both sides by 11:
n = 12
