Answer:
B
Step-by-step explanation:
First thing to do here is to calculate the z-score
Mathematically;
z-score = (x-mean)/SD
here, x = 130, mean = 120 and SD = 10
Substituting these values
z-score = (130-120)/10 = 10/10 = 1
So the probability we want to calculate is;
P(z ≥ 1) = 1 - P(z <1)
From standard score table, P(z <1) = 0.15866
P(z ≥ 1) = 1-0.15866 = 0.84134
Answer: no, you add the exponents.
Step-by-step explanation:
X = 56°.
Based on the congruence statement, m∠L = m∠P; m∠M = m∠Q; and m∠N = m∠R.
Since m∠L = 72°, m∠P = 72°.
Since m∠N = x°, m∠R = x°.
We are given that m∠Q = 52°.
We can find the value of x by subtracting the given angles from 180:
180-(72+52) = 180-124 = 56°
Answer:
distance between a number and zero
|a| = a if a >= 0 and |a| = -a if a < 0
|4| = 4 and |-4| = 4
nonnegative
symmetric over the y-axis
left line is y = -x for x < 0
right line is y = x for x >= 0
Axis of symmetry: y-axis
Vertex: (0, 0)
