Answer:
34
Step-by-step explanation:
The sum of the angles of a triangle is 180
26x+6 + 21x-1 +11x+1 = 180
Combine like terms
58x +6 = 180
Subtract 6 from each side
58x = 180-6
58x = 174
Divide by 58
58x/58 =174/58
x=3
We want <C
<C = 11x+1 = 11*3+1 = 33+1 = 34
Answer:
Step-by-step explanation:
From the information given :
The null hypothesis 
The alternative hypothesis 
Given that:
the sample size n = 21
sample standard deviation s = 68
population standard deviation σ = 60
a) The level of significance 
b) The chi-square statistics can be calculated as:




The degree of freedom is :
= n - 1
= 21 - 1
= 20
Answer:
18≤ 2.50x
because there is only so much money she is allowed to spend has to be less than or equal to 18
Not sure what you mean by dot product, maybe explain and I can help better but the two make an equation of y= 4/1 x + -27, that is the equation of the line.
