Answer:
Therefore, we conclude that it is the first quadrant.
Step-by-step explanation:
We know that the x coordinate is the temperature in C and the Y coordinate is the change in number of people who re sledding.
We have a point showing 8 degrees Celsius above zero and increase of 4 people sledding.
Therefore, we conclude that it is the first quadrant.
We use the software to drawn a graph.
This is a bad example but if the arrow has a line underneath you fill in the circle on “-3”
and since X is greater than -3 you shade everything after it
Using addition of variables, it is found that the mean of S is of 73 and the standard deviation is of 8.5.
<h3>What happens to the mean and the standard deviation when two variables are added?</h3>
- The mean is the sum of the means.
- The standard deviation is the square root of the sum of variances.
In this problem, for variables A and B, we have that:
![\mu_A = 35.5, \sigma_A = 5.1](https://tex.z-dn.net/?f=%5Cmu_A%20%3D%2035.5%2C%20%5Csigma_A%20%3D%205.1)
![\mu_B = 37.3, \sigma_B = 6.8](https://tex.z-dn.net/?f=%5Cmu_B%20%3D%2037.3%2C%20%5Csigma_B%20%3D%206.8)
Variable S is the sum of A and B, hence:
![\mu_S = \mu_A + \mu_B = 35.5 + 37.3 = 73](https://tex.z-dn.net/?f=%5Cmu_S%20%3D%20%5Cmu_A%20%2B%20%5Cmu_B%20%3D%2035.5%20%2B%2037.3%20%3D%2073)
![\sigma_S = \sqrt{\sigma_A^2 + \sigma_B^2} = \sqrt{5.1^2 + 6.8^2} = 8.5](https://tex.z-dn.net/?f=%5Csigma_S%20%3D%20%5Csqrt%7B%5Csigma_A%5E2%20%2B%20%5Csigma_B%5E2%7D%20%3D%20%5Csqrt%7B5.1%5E2%20%2B%206.8%5E2%7D%20%3D%208.5)
The mean of S is of 73 and the standard deviation is of 8.5.

Answer:
8931
Step-by-step explanation:
1 1 1
21 x 18 x 13 = 4914
16 x (18x13) = 3744
13 x 21 = 273

(I am not 100% Sure, you should double check)
==> I noticed that to draw a B or a D, you have to use both straight and curved lines. Maybe that's the pattern.
Hold up, hee haw, whoa ! There are no curved lines, only straight ones, in F and H. That can't be the pattern.
==> I noticed that to go from B to D in the alphabet, you skip one letter (C). Maybe that's the pattern.
Well Hyola ! If you skip one letter in the alphabet each time, you can get from D to F, and then from F to H, and then from H to J .
I'm willing to go out on a limb, bet 3¢ , and state my conjecture that the pattern is "To get from one term to the next term, skip one letter in the alphabet.".
I can't be absolutely positive and say "That's definitely it !". There may be other patterns that can produce the same 5 letters but then not work after that. But the pattern of "Skip-one" can produce these 5 letters, so it's a reasonable conjecture.
