33.75 i think
Multiply 9 by 3 you get 27
Divide 9 by 4 and get 2.25
Multiply 2.25 by 3 which is 6.75
Add 27 and 6.75
33.75
Answer:
x = 7.5
y = 75
Step-by-step explanation:
if one angle of an equilateral triangle is 60 degrees (180/3) then 4x + 2x + 2x = 8x = 60, so x = 7.5
for y, we'll have to take the right triangle. we know that 2x = 15, and MON = 60, so 180 - 60 - 15 = 105.
180 - 105 will give us y, which is 75
For the given vectors 
and 
The dot product of vectors a and b is defined as = 
So, 
= -16+12
= -4
Answer:
Arthur knows that there is a difference among the groups somewhere, but he does not know where
Step-by-step explanation:
An ANOVA test is a test to find out whether the results of an experiment or a survey are significant or not. ANOVA test helps the researcher or the experimenter to decide whether they reject the null hypothesis or accept the alternate hypothesis in the experiment. In ANOVA test, the experimenter wants to find if there is a difference between them or not.
In the context, Arthur is doing a study and he wishes to find out effect of a sleep deprivation on the number of the calories that people consumed. He collects some data from his subject group from the sleep lab and after running the ANOVA test, he finds out that he can reject the null hypothesis. So on this basis, Arthur knows that there is some basic difference among the members of the group somewhere, but he does not know where actually the difference is.
