Use arccos...cos^-1 so
cos^-1 (0.8195)
it equals 34.96522689°
The answer is B.
The numbers are doubling but it's also a constant positive and negative
Answer:
0.0009
Step-by-step explanation:
n = 8
This is the left tailed test .
The null and alternative hypothesis is ,
Test statistic = z=-3.12 from the table.
P(z <-3.12 ) = 0.0009
P-value =0.0009
Answer:
Step-by-step explanation:
You have to use the triangle inequality theorem:
12cm, 4cm, xcm
x > 4cm - 12cm
x > -8cm
x < 12cm - 4cm
x < 8cm
-8cm < x < 8cm
Answer: -1
Step-by-step explanation: First, factor out 3.6. You should get -m+3. Since the coefficient is just the number being multiplied to the variable (which is m here), your coefficient should be -1 because m is being multiplied to -1 to make -m. Hope this helps!
