Answer with explanation:
Given : The computed r -value = 0.45
Sample size : n=18
Degree of freedom : 
Now, the critical value for Pearson correlation coefficient for a two-tailed test at a .05 level of significance will be :
( by critical correlation coefficient table)
Since , 
i.e. 0.45>0.468 , then we say that his Pearson correlation coefficient is not significant for a two-tailed test at a .05 level of significance.
Answer:
the answer is 33
Step-by-step explanation:
because 800 divided by 24 equals. 33
Answer:
A sandwich costs $7.5
Step-by-step explanation:
Given
Represent chips with c and sandwiches with c
From the question, we understand that 5 sandwiches were ordered.
Hence, the question of the system is:
Substitute values for Total and c
Collect Like Terms
Divide both sides by 5
Answer:
26.9
Step-by-step explanation:
Right now we have '8' in the tenths place. That '6' following the '8' requires us to round up. Thus, 26.86 to the nearest tenth is 26.9.
27 multiplied by 10 will give you the answer. 27 x 10 = 270.
