Answer:
The critical value for the 95% confidence interval is z = 1.96.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of 
So it is z with a pvalue of
, so z = 1.96.
The critical value for the 95% confidence interval is z = 1.96.
Step-by-step explanation:
Given
mass (m) = 5000 kg
velocity (v) = 100 km/h = 100* 1000/ 3600 = 27.78m/s
Now
Kinetic energy
= 1/2 mv²
= 1/2 * 5000 * 27.78²
= 1929321 joule
Answer:
Replace x with −x.
f(x) = 3(2)−x is not correct because the y-intercept is (0, 3).
the answer is B
Step-by-step explanation:
80 degrees since the corrisponding angle, A, is also 80 degrees
Answer:
it should be 67/65 or if in mixed number form : 1 2/65
