write slope form of lines satisfying the given coditions then use the point slope form of the eqation to write the slope intercept form of the equation slope = 4, passsing through (-3,9)
Answers
Here is how to find the equation of the line using point-slope form
Formula for the equation of a line in point-slope form: y - y₁ = m(x - x₁)
Now that we have the formula, we plug in what we are given.
y - 9 = 4(x + 3)
We can covert this into slope-intercept form by solving for y.
[tex]y - 9 = 4(x + 3)\\\\y - 9 = 4x + 12\\\\y = 4x + 21[/tex]
Our equation for this line is: y = 4x + 21.
We can prove this by graphing the line, like so:

Find the critical value Zc necessary to form a confidence interval at the level of confidence c=0.82 what does Zc=
Answers
Answer:
The z-critical values are:
[tex]z_{0.09}=-1.34\\\\z_{0.91}=1.34[/tex]
Step-by-step explanation:
The confidence level is, c% = 82%.
The significance level for the two tails are:
Left tailed:
[tex]\frac{\alpha}{2} =\frac{1-c\%}{2}[/tex]
[tex]=\frac{1-0.82}{2}\\\\=\frac{0.18}{2}\\\\\=0.09[/tex]
Right tailed:
[tex]1-\frac{\alpha}{2} =1-\frac{1-c\%}{2}[/tex]
[tex]=1-0.09\\\\=0.91[/tex]
The z-critical values are:
[tex]z_{0.09}=-1.34\\\\z_{0.91}=1.34[/tex]

‐2(‐5i-4)+i+1 = 119
Answers
Answer:
i = 10
Step-by-step explanation:
-2(-5i-4)+i + 1=119
Distribute -2 into whats in the parentheses
10i+8+ i+1=119
Now combine like terms
(10i + i)+ (8+1)= 119
11i + 9 = 119
Subtract 9 from both sides
11i + 9-9= 119-9
11i = 110
Now divide by 11
11i/11 = 110/11
i= 10

That will be misleading because the average is not very representative of the actual distribution. The actual distribution of offers is highly skewed toward lower values.
