Answer:
the probability of observing 27 or more students 0.818
Step-by-step explanation:
given data
sample n = 28 students
population = 93%
to find out
the probability of observing 27 or more students
solution
we will find Z value for CI 93%
from z table we get Z is 1.812 for Cl 93%
so P(27 ≤ Z ≤ 28)
we know Z = 0.182
= 1 - 0.182
= 0.818
the probability of observing 27 or more students 0.818
Answer:
Step-by-step explanation:
3(y + 2) = 14
3y + 6 = 14
3y = 14 - 6
3y = 8
y = 8/3 or 2 2/3
Y = -2x^2
h = Xv = -B/2A = 0/-4 = 0.
k = -2*0^2 = 0.
V(0,0).
Use the following points for graphing:
Y = -2x^2.
(x,y)
(-2,-8)
(-1,-2)
V(0,0)
(1,-2)
(2,-8)
Y = -2x^2 + 4.
h = Xv = -B/2A = 0/-4 = 0.
k = Yv = -2*0^2 + 4 = 4.
V(0,4).
(-2,-4)
(-1,2)
V(0,4)
