Y = 3x - 2 
I assume this is what they mean;
3(1)- 2 = 1 for  <span><span>x = 1

</span>Fill in the x's with the following numbers. so first... (x = 2)
</span>y = 3x - 2  
     3(2) - 2
multiply 3 and 2 and then minus 2
which equals 4 all together
y=4 
therefore; 
3(2) - 2 =  4

For x = 3
Fill in the x with 3 in the equation
3x - 2 = y
3(3) - 2 = y 
9 - 2 = y
equals 7
so...
3(3) - 2 = 7

Do the same rule with number 4 :)

The mean incubation time of fertilized eggs is 21 days. Suppose the incubation times are approximately normally distributed with
Korvikt [17]

Answer:

a) 20.16; b) 20.49 and 21.51

Step-by-step explanation:

We use z scores for each of these.  The formula for a z score is

z=\frac{X-\mu}{\sigma}.

For part a, we want the 20th percentile; this means we want 20% of the data to be lower than this. We find the value in the cells of the z table that are the closest to 0.20 as we can get; this is 0.2005, which corresponds with a z score of -0.84.

Using this, 21 as the mean and 1 as the standard deviation,

-0.84 = (X-21)/1

-0.84 = X-21

Add 21 to each side:

-0.84+21 = X-21+21

20.16 = X

For part b, we want the middle 39%.  This means we want 39/2 = 19.5% above the mean and 19.5% below the mean; this means we want

50-19.5 = 30.5% = 0.305 and

50+19.5 = 69.5% = 0.695.

Looking these values up in the cells of the z table, we find those exact values; 0.305 corresponds with z = -0.51 and 0.695 corresponds with z = 0.51:

-0.51 = (X-21)/1

-0.51 = X-21

Add 21 to each side:

-0.51+21 = X-21+21

20.49 = X

0.51 = (X-21)/1

0.51 = X-21

Add 21 to each side:

0.51+21 = X-21+21

21.51 = X
