Answer:
<em>The first step is to determine the average
</em>
![x= \frac{0,6+0,7+ 0,7+0,3+0,4+ 0,5+ 0,4 +0,2}{8}\\\ x= 0,475](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B0%2C6%2B0%2C7%2B%200%2C7%2B0%2C3%2B0%2C4%2B%200%2C5%2B%200%2C4%20%2B0%2C2%7D%7B8%7D%5C%5C%5C%20x%3D%200%2C475)
<em>The exercise says it’s a normal distribution: (n=8)</em>

<em>According to the exercise, the mean is equal to 0,5 then the value of t of the distribution can be obtained
</em>
<em />
![t= \frac{x-u}{\frac{s}{\sqrt{n} }}\\\ t= \frac{0,475 - 0,5}{0,183}\\\ t= -0,3860](https://tex.z-dn.net/?f=t%3D%20%5Cfrac%7Bx-u%7D%7B%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%20%7D%7D%5C%5C%5C%20t%3D%20%5Cfrac%7B0%2C475%20-%200%2C5%7D%7B0%2C183%7D%5C%5C%5C%20%20t%3D%20-0%2C3860)
<em>The variable t has 7 grade to liberty, we calculate the p-value as:

![2* P(t < - 0,3860)= \\\ 2* 0,3554 = 0,7108](https://tex.z-dn.net/?f=2%2A%20P%28t%20%3C%20-%200%2C3860%29%3D%20%5C%5C%5C%202%2A%200%2C3554%20%3D%200%2C7108)
This value is very high, therefore the hypothesis is not rejected
Answer:
See explanation
Step-by-step explanation:
The question is incomplete, however, one of the requirements of this question while I searched, was to make a table and sketch the equation.
If this is the case, then, all you need to do is take the equation, Assume some values for x, and compute the values of y. Then, you can do the graph.
I begin with value from 0 to 10.
This is the example of calculations:
x = 0
y = 18.25*0 = 0
for x = 0, we get y = 0. For x = 2:
y = 18.25 * 2 = 36.5
If we keep doing this, we should get a straight line. See the graph and attached table. If the question is asking another thing, then please get back to me to answer it.
Answer:
1/6 ; 2/6 ; 2/6
Step-by-step explanation:
To split 5/6 into. 3 different fractions with the same denominator and different numerator values;
The integer value of the numerator 5 can be divided into 3 different whole Number values ;
It could be :
5 = 3 + 1 + 1
5 = 2 + 2 + 1
Hence, we could have ;
3/6 +. 1/6 + 1/6
Or
2/6 + 2/6 + 1/3
Width of the rectangle is 14 ft
Step-by-step explanation:
- Step 1: Let the width of the rectangle be x. Then length = 8 + x. Perimeter = 72 ft.
Perimeter = 2(length + width)
72 = 2 (8 + x + x)
72 = 16 + 4x
4x = 56
x = 56/4 = 14
∴ Width of the rectangle is 14 ft
