Answer:
14.625
Step-by-step explanation:
As per the situation the solution of mean and standard deviation change, based on all 12 samples is represented below:-
Mean of all 12 samples is shown below:-


So, the Mean = 23.5
and now,
The Standard deviation of all 12 samples is shown below:-
![= \sqrt{\frac{1}{12}} (36-23.5)^2+(14-23.5)^2+(21-23.5)^2+(39-23.5)^2+(11-23.5)^2+(2-23.5)^2+(33-23.5)^2+(45-23.5)^2+(34-23.5)^2+(17-23.5)^2+(1-23.5)^2+(29-23.5)^2}]](https://tex.z-dn.net/?f=%3D%20%5Csqrt%7B%5Cfrac%7B1%7D%7B12%7D%7D%20%2836-23.5%29%5E2%2B%2814-23.5%29%5E2%2B%2821-23.5%29%5E2%2B%2839-23.5%29%5E2%2B%2811-23.5%29%5E2%2B%282-23.5%29%5E2%2B%2833-23.5%29%5E2%2B%2845-23.5%29%5E2%2B%2834-23.5%29%5E2%2B%2817-23.5%29%5E2%2B%281-23.5%29%5E2%2B%2829-23.5%29%5E2%7D%5D)
= 14.625
Therefore, we used the above equation to reach the answer.
The solution of inequality is C < -40
<em><u>Solution:</u></em>
Given that the inequality that is used to find the celsius temperature that are less than -40 fahrenheit
To find: solution of inequality
<em><u>Given inequality is:</u></em>

So we have to solve the above inequality for C

Add -32 on both sides

Multiply both the sides by 

Thus the solution of inequality is C < -40

ABOUT THIS TUTOR ›
y=mx + b is the standard slope intercept form for a line
m=1/2, b =-2
y=(1/2)x -2. y-intercept is -2 or the point (0,-2)
x intercept is found by setting y=0 and solving for x
0=(1/2)x - 2
(1/2)x = 2
x = 4 = the x intercept or (4,0)
plot the 2 intercepts (0,-2) and (4,0)
(4,0) is on the x axis, 4 units to the right of the origin (0,0)
(0,-2) is on the y axis, 2 units below the origin
once you plot those two points, draw a straight line connecting them. That's the graph of the line
For this graph the equation is x= -3
Because in the coordinates you gave, all the x values are -3 telling me that the line is a straight vertical line passing through the -3 x-axis and has no y-intercept as it's a vertical line, not diagonal, so it's not passing through the y-axis. Plus because of this too this line has no gradient.
