There are six blue balls and four red balls in the
pocket. Take out a ball at random, check the color and put it back
in the pocket.
1. If you take the ball out until the red one comes out, what is
the probability that the ball will be drawn exactly five times and
the experiment is over?
2. What is the average and variance of the number of times X is
taken if the ball is pulled out until the red ball comes out?
3. Repeat the procedure ten times to remove the ball from the
pocket. Find the mean and variance of the number of blue balls
taken Y.

Red and white blood cells develop from a common hematopoietic stem cell, which is large and nucleated. After cell differentiation and maturation, red cells no longer have nuclei and are very small, and white cells are nucleated, often large, filled with granules, and are capable of phagocytosis. Why do mature red blood cells look so different from their white counterparts?
What is the term for white blood cells? How many types are there and what does each one do? Come up with an easy way to remember the names of the different types (develop an acronym).

emergency physics question!
what is the minimum film of coating with index of refraction of 1.52 on a glass with index of refraction of 1.40 for which destructive interference of a red component of white light in air can take place by reflection? assume the wavelength of the red component in vacuum is 650nm. find the minimum visible wavelength in vacuum for constructive interference due reflection for the thickness of the coating film you found.
what should be the minimum additional coating to get constructive interference for the red component of 650nm?
not just an answer, I need help understand the answer and the question!
STEP BY STEP explanation please!

A company produces thousands of plastic toy parts every day. So that the toys can be assembled properly a certain tab thickness x has to meet quality control specifications. The mean of the population of x has to be within a certain range and the standard deviation of population of x has to be less than a certain value. A quality control inspector took a random sample of 18 parts and measured x.He computed a sample mean of 8.2mm for x and a sample standard deviation of 0.024mm. Having found the mean was in spec next he has to test sample variance to decide whether to reject the null hypothesis that the population variance of x is less than or equal to the quality tolerance 0.0002 mm2 using an alpha og 0.05. He assumes the population mean follows a normal distribution?
A) draw a diagram that shows reject/fail to reject regions for this problem?
b)What is the statistic used
c) What is the test statistic value computed from the sample statistics given
D) Since the level of significance alpha is 0.05 state the critical value(s) which would be use relevant to the question. State your conclusion about the null hypothesis.
