1. Equation: 4x + 6y = 40
Answer:!4x + 6y - 40 = 0
2x + 3y - 20 = 0
2. Equation: 2x + 6y = 26
Answer: 2x + 6y - 26 = 0
x + 3 y - 13 = 0
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.
6/7 because it’s a smaller fraction with more pieces. Brainliest???
Answer:
1200 words
Step-by-step explanation:
If he types 40 words a minute, you have to multiply that by thirty because he typed 40 words 30 timers. 40 x 30=1200
The answer for 10x - 2y = 20 is y= 5x - 10
The answer for 5x = y + 10 is y = 5x - 10
so basically from this 5x - 10 is the results and 10x - 2y = 20 and 5x = y + 10 are different problems that lead to the same result, hope this helps
