Answer:
-pi/3
Step-by-step explanation:
To convert from degree to radians, multiply by pi/180
-60 * pi/180 = -60/180 *pi = -pi/3
Answer:
It's a parabola.
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Construct a perpendicular bisector of segment AB.
Perpendicular bisector is a line that divides the line into two equal halves forming 90° at the intersection point.
So, points A and B will be at the same distance from the intersection point.
If the constructed line (perpendicular bisector) is the reflection axis, then point B will be the refection point of A.
Answer:
E. When the sample size increases, because the standard deviation of the distribution of sample means better estimates the population standard deviation for larger sample sizes.
Step-by-step explanation:
- T distribution is similar to the normal distribution and is seen when the estimates of the variance are based on the degree of freedom and has a relatively more score in its tail and has a greater change of extreme values.
Using the hypergeometric distribution, it is found that there is a 0.0002 = 0.02% probability that exactly 6 patients will die.
<h3>What is the hypergeometric distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- N is the size of the population.
- n is the size of the sample.
- k is the total number of desired outcomes.
The values of the parameters for this problem are:
N = 25, k = 6, n = 8.
The probability that exactly 6 patients will die is P(X = 6), hence:
0.0002 = 0.02% probability that exactly 6 patients will die.
