Answer:
Option 3) We reject the null hypothesis with one tail test and accept the null hypothesis with two tail test.
Step-by-step explanation:
We are given the following information:
n = 16


Now,
Right One-tail Test


We reject the null hypothesis in this case.
Two-tail Test
Now,

We accept the null hypothesis in this case.
Option 3) We reject the null hypothesis with one tail test and accept the null hypothesis with two tail test.
Setting d = 0 gives the points where she is at the surface.
therefore 0= 0.1t^2 - 3.5t + 6
apply the quadratic formula to get t = (3.5+- √12.25-4*0.1*6)/0.2
t = (3.5 <span>3.1384709653)/0.2
t= </span>1.80764517352 and <span>33.1923548265
</span>subtract the 2 to get the time difference between entry and exit you get
Δt = <span>31.384709653 seconds
</span>
That's as long as I haven't made a mistake :D
It is the 3rd one your welcome
Answer:
r=1
Step-by-step explanation:
First we need to know the length of each side of the triangle, so we use the formula of the vector modulus:

By doing so, we find:

With this we know that the triangle is not right, but, we assume the longest side as the hypotenuse of the problem.
As we have two equal sides, we know that the line between point |AB| and the center of the hypotenuse is perpendicular, therefore, we can calculate it using Pythagoras theorem:
