Answer: you minus the equations you have to get the equation that you want so it all can add up to that *
Step-by-step explanation:
6x-2=5x+29
6x-5x-2=29
x-2=29
x=31
I assume that you want to know the temperature at a certain timing.
Well, you know that at 12:00 pm, the temperature was 12 F and that it decreases by a steady rate of 2 F each hour.
This means that at 1:00 pm, the temperature was 12-2 = 10 F
At 2:00 pm, the temperature was 10-2 = 8 F
At 3:00 pm, it was 8-2 = 6 F
.......and so on
You can follow this sequence to the timing you are looking for.
Answer:

Step-by-step explanation:
The equation of the ellipse is

If the vertex of the ellipse is at point (-7,0), then a=7.
If the co-vertex of the elllipse is at point (0,-5), then b=5.
The equation of the ellipse is


Answer:
We are given:

Margin of error 
Confidence level = 0.99
We need to find the sample size to estimate the proportion of people who carry the TAS2R388 gene.
The formula for finding the sample size is:

Where:
is the critical value at 0.01 significance level.
Therefore, the required sample size is:



Therefore, the required sample size is 3774
