Answer:
See below.
Step-by-step explanation:
Cos O is positive in the first and 4th quadrants and sin O is negative in the 3rd and 4th quadrants.
So the answer is Quadrant 4.
cos^2 O = 1 - sin^2 O
= 1 - (-3/5)^2
= 16/25
So cos O is +√(16/25)
= 4/5.
Answer:
the correct answer is choice 2
Step-by-step explanation:
reason being that both bc and ac would both be vertical lines so they have the same slope of undefined
The answer is $113 because you add the money

Answer:
p value = 0.302
Step-by-step explanation:
Given that all cars can be classified into one of four groups: the subcompact, the compact, the midsize, and the full-size. There are five cars in each group. Head injury data (in hic) for the dummies in the driver's seat are listed below.
H_0: All cars have same mean values
H_a: atleast two cars have different mean values
(Two tailed anova test)
Anova: Single Factor
SUMMARY

Subcompact 5 3444 688.8 48502.7
compact 5 2879 575.8 4582.7
Midsize 5 2534 506.8 18720.2

Since p value of 0.302 is greater than 0.05 significance level we accept null hypothesis.
p value = 0.302
