let f(r)=sin^3r/cos^3r
so f(-r)= (sin(-r)/cos(-r))^3
=(-sinr/cosr)^3
=-f(r)
so it is odd function
Answer:
F. Slope: 0
A. Equation: <em>y</em><em> </em>= -1
Step-by-step explanation:
Anything that is set to equal <em>y</em><em> </em>is considered a horizontal line, which is known as a zero slope, therefore, you have your answers.
I am joyous to assist you anytime.
I’m not sure what that is
Answer:
The training does reduce response time at 0.05 level of significance
Step-by-step explanation:
Population mean for a population with normal distribution, where the standard deviation is known and the appropriate significant test is given then;
z=x-μ / δ/√n
where
μ= 9 minutes
x=8 minutes
δ= 4.2
n= 36
Applying the formula;
z= 8-9 / 4.2/√36
z= -1 / 4.2/6
z= -1 /0.7 = - 1.429
Perform the test where
H₀ : p=0.05 verse Ha : p < 0.05
Using the Z-table, find the probability that Z is less than -1.43.
You will find the probability of 0.0764 of Z being more than the value in test thus; there are high chances that results will be observed according to the null hypothesis
