The margin of error of the random selection is 0.29
The given parameters are:
--- the sample size
--- the standard deviation
--- the mean
--- the confidence level.
The margin of error (E) is calculated as follows:

So, we have:


The z-value for 90% confidence level is 1.645.
Substitute 1.645 for z


Take square roots

Multiply

Approximate

Hence, the margin of error is 0.29

Answer:
The equation of Line is y = - 8x + 7
Step-by-step explanation:
Given as :
The slop of line is - 8
And The y intercept is 7
As the equation of line is y = mx + c
For y intercept , x = 0
So, With y intercept and slop ,
7 = (-8)× (0)+ c
Or, c = 7
So the equation of line is
y = mx + c
I.e y = ( - 8 ) x + 7
Hence The equation of Line is y = - 8x + 7 Answer
Answer:
c then d my man I got you maybe
You can add, subtract, and multiply them. These three operations obey the rules for integers. There's a polynomial division algorithm that fills formally the same role as the usual division algorithm for integers. Polynomials added to, subtracted from, or multiplied by other polynomials yield only polynomials. Likewise, integers added to, subtracted from, or multiplied by other integers yield only integers.
