Answer:
y = 2x + 3
Step-by-step explanation:
y = 2x - 8 passes through ( 1,5 )
y = 2x + 3 is parallel to y = 2x - 8 because it has the same m( 2x)
and it also passes through ( 1, 5 )
Try Desmos, very helpful
Hope this helps
4.76 rounded to one decimal place is 4.8~
To figure it out u plug in ur x value then multiply it by 2 to get ur y value. So if u had a value of 1 for ur x value ur y value would be 2
Answer:
The 90% confidence interval of the population proportion is (0.43, 0.56).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population proportion <em>p</em> is:

The information provided is:
<em>X</em> = 74
<em>n</em> = 150
Confidence level = 90%
Compute the value of sample proportion as follows:

Compute the critical value of <em>z</em> for 90% confidence level as follows:

*Use a <em>z</em>-table.
Compute the 90% confidence interval of the population proportion as follows:


Thus, the 90% confidence interval of the population proportion is (0.43, 0.56).
