Answer:
Step-by-step explanation:
Answer:
has a slope of 1/3 and passes through the point (-3, 1)
Answer:
sum of interior angles of octagon is 1080 degrees
From figure ,
136 + 132 + 129 + 116 + 158 + 141 + 124 + x = 1080
so, x = 1080 - 936
= 144
Step-by-step explanation: Simply add the angles and substract the sum from 1080 which is the sum of interior angles of octagon
Plot them on the chart by <em>x </em>going first and then <em>y </em> so its going to be (-x,y) or (x,y) or (-x, -y) or (x,-y)
<h2>
Answer with explanation:</h2>
Let
be the population mean.
For the given claim , we have
Null hypothesis : 
Alternative hypothesis : 
Since alternative hypothesis is two-tailed , so the test is a two-tailed test.
Given : Sample size : n=220 ;
Sample mean:
;
Standard deviation: 
Test statistic for population mean:


By using the standard normal distribution table of z , we have
P-value ( two tailed test ) : 

Since , the P-value is greater than the significance level of
, it means we do not have sufficient evidence to reject the null hypothesis.
