Answer:
y = - 1/2x + 5
Step-by-step explanation:
y = 2x – 6 slope = 2
Perpendicular line slope = -1/2
for (4 , 3) y = mx + b y = 3, x = 4, m = -1/2
b = y - mx = 3 - (-1/2) x 4 = 5
equation: y = - 1/2x + 5
Answer:
Step-by-step explanation:
Given that the mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days.
Let X be the incubation time for a type of fertilized egg kept at a certain temperature is 25 days.
X is N(25, 1)
a) Normal curve is in the attached file
b) the probability that a randomly selected fertilized egg hatches in less than 23 days
=
we convert x into Z score and use std normal distn table to find probability

i.e. we can say only 2.5% proportion will hatch in less than 23 days.
