Using a calculator for the chi-square distribution, the critical value is given by:
A) 20.090
<h3>How to find the critical value of the chi-square distribution?</h3>
For a chi-square critical value, three parameters are needed:
- The number of degrees of freedom, which is one less than the sample size.
In this problem, we have a one-tailed test(as we are testing if the mean is greater than a value), with a significance level of 0.01 and 8 df, hence, using a calculator, the critical value is of 20.09, hence option A is correct.

Answer:
Fundamental Counting Principle problem and determining the number of ways it can be fulfilled is described below in detail.
Step-by-step explanation:
The fundamental counting principle pronounces that if there are p approaches to do one thing and q approaches to do a different thing, then there are p×q approaches to do both actions. possible consequences of the operation. The counting principle can be stretched to circumstances where you have more than 2 alternatives.
The minimum cost for this spanning tree has been calculated as $1100.
<h3>How to solve for the minimum spanning tree</h3>
This is solves as
AC + CD + DF + FE + EB
This would be
15 + 25+ 23 + 22 + 25
= 110
The minimum cost would be gotten by multiplying this valus with the amount per foot
= 10 * 110
= $1100
Hence the minimum cost of the spanning tree is $1100

M=(y2-y1)/(x2-x1)
m= (7-(-2)/(-3-6)
m=7+2/-9
m=9/-9
m=-1
The slope is -1.

Answer:
6
Step-by-step explanation:
To figure out what needs to be multiplied, we need to find the least common denominator. By finding this, we know that what we multiply the equation with will be a multiple of each denominator, meaning that there will be no fractions left.
We can find the least common denominator by listing multiples of each fraction, and finding which one is the smallest but still in each list.
3: 3, 6, 9, 12...
2: 2, 4, 6, 8...
6: 6, 12, 18, 24...
We can notice that 6 is the lowest number in each list. Therefore, 6 is our least common denominator, and if we multiply by 6, the fractions will be removed.
