Answer
0.975 is the probability value
Step-by-step explanation:
We start by getting the z score of 86
z-score = (x - mean)/SD
z-score = (86-98)/6 = -12/6 = -2
So we want to find the probability of z greater than or equal to 2
We shall be using the standard normal distribution table here
We have the answer as;
0.975
Answer:
D.
Step-by-step explanation:
A is linear, you can figure out that y=x+5
B is linear, y=22(x+1)
C is linear, y=8x+5
D is exponential, y=3ˣ⁺¹
Deriving these formulas is a matter of trial and error if you know you can choose between linear and exponential.
X² = 1/4 ⇒√⇒ x₁ = 1/2, x₂ = -1/2
BD is a perpendicular bisector of AC, that’s the answer!!!
