Start at 5 and go up 3 and move 4 to the right
If we divide 12.6/4.5 by 3 we receive 4.2/1.5. So yes they are proportional. <span />
Answer:
p= 0.9995 and we can conclude that students receiving aid is more than 50% according to the sample results in 2% significance level.
Step-by-step explanation:
: less than or equal 50% of students at his college receive financial aid
: more than 50% of students receive financial aid.
According to the nul hypothesis we assume a normal distribution with proportion 50%.
z-score of sample proportion can be calculated using the formula:
z= where
- X is the sample proportion (0.65)
- M is the null hypothesis proportion (0.5)
- s is the standard deviation of the sample ()
- N is the sample size (120)
then z= ≈ 3,29
thus p= 0.9995 and since p<0.02 (2%), we reject the null hypothesis.
Answer:6/8
Step-by-step explanation:
Since the interior angles of a triangle equal 180°, then 180-45=135.
Then you would use 135 to find the remaining two angles: b+3b=135.
4b=135.
Divide to find b. And the plug in whatever b is for the to figure out Angles B and C.
However, I believe the equation it's looking for is: 180=45+b+3b OR 45+4b=180
