Answer:
I want to say its C - 8.12 units. But I think it could also be D- 8.25 units. Just not 100% sure.
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:
you could either say p(y+z)+y(y+z)or y(p+y)+ z(p+y)

Step-by-step explanation:
Let A be the area of the sector of circle.
1st card : 3 steps forward
2nd card: 3 steps back
3rd card: 4 steps back
4th card: 5 steps forward
5th card: 10 steps forward
6th card: 7 steps back
Total steps : 3 + 3 + 4 +5 +10 + 7 = 32
Answer: D) 32
