• Topic #1: My Philosophy of Counseling. Write an essay describing your basic beliefs about how you view counseling, the purpose of counseling, your role as a helper, and what you would expect of your clients. Why are you interested in the helping professions? What kind of work would you like to pursue? What you hope to learn from the class? What personality characteristics or life-experiences do you feel will help you to become a counselor?

In Austin (TX). there is a taco food truck called Eddy's Tacos. Their business parlor is usually quite busy, with a queue down the block. If there are customers still in the queue at closing time, they must be turned away.
In this example, let's say around 1,576 people visit this establishment per day to try out these tasty tacos. They are open are at 10AM and close at 4PM.
We will assume that the customers enter at an equal rate for each hour they are open. They have the ability to serve around 225 customers per hour.

How long does a customer arriving at 1:30 PM wait to be served? Answer should be expressed in minutes, and you should round to the whole minute if needed.

A sample of 0.1364 g of an unknown monoprotic acid was dissolved in 20.0 mL of water and titrated with 0.080M NaOH. The acid required 23.0 mL of base to reach the equivalence point.

(a) What is the molar mass of the acid in (g/mol)?

(b) After 12.0 mL of base had been added in the titration, the pH was found to be 5.78. What is the K_a for the unknown acid?

I need help on this, please number the answer with the question

Answer the following question:

1. Name and describe, in detail, two reasons why an LD50 values isn’t necessarily useful for someone to know. Pick ONE of the two reasons you described and explain an experiment you could perform to try and help make it more useful to humans. You can have an unlimited budget and access to anything you need that exists currently however you are not allowed to experiment on humans. (7 marks)

I need to design a model and draw it or construct (more advanced) such as a "SPECIAL BLOOD PRESSURE MACHINE PRODUCT THAT IS A WIRELESS, REMOTE MONITORING DEVICE THAT CONNECTS TO A SMARTPHONE APP WITH ACCURATE MEASUREMENTS" for prototyping.

Is it possible to perform a statistical test if the data being analyzed violates one of the test's assumptions? Why or why not?

Based on your answer to the previous question, give an example of a cutoff score that would be statistically significant for one type of test (Z or t) but not the other.

G and g are dominant and recessive alleles, respectively, for a gene. If a mating of a gg female with a Gg male resulted in offspring that all have the recessive phenotype, this would most likely be an example of
