Answer:
28 250
Step-by-step explanation:
25 000*8%=2000
25 000*5%=1250
25 000+1 250+2 000=28 250
2.5 is the mean of this distribution.
What is the distribution's mean?
- The expected value, commonly known as the mean of a statistical distribution with a continuous random variable, is calculated by integrating the product of the variable's probability as described by the distribution.
- The lowercase Greek letter mu () stands for the expected value. A probability of 50% equals zero standard deviations, and the mean is in the middle of the normal distribution.
Given: p = 0.05 and n= 50
Mean of the binomial distribution = n×p = 50 × 0.05 = 2.5
Therefore, option a is the correct answer. Other options are incorrect because these are irrelevant.

Answer:
straight line and line goes through the origin.
Step-by-step explanation:
without a graph, you will need to divide y/x to seeing there is a constant rate or a constant number every time you divide.
Well the slope formula is y² - y¹ / x² - x¹.
If there was a picture I could help!
A. The discriminant is 81. The formula is b^2 - 4ac.
B. 2 answer and both will be rational due to the fact that the discriminant is a perfect square.
C. Solutions are 1/2 and -4. You can find using the quadratic formula.
