How can scientists know for sure that the cell theory is true? What evidence do we have to prove it?
Akimi4 [234]
I agree with it.The most widely accepted theory is that the first cells were created by groups of molecules working together to make the basic biomolecules (Carbs, Lipids, Proteins, Nucleic Acids). These biomolecules eventually found each other and supported each other creating cells. Over millions of years these unicellular organisms evolved into multicellular organisms, eventually leading up to humans and other common life forms today.

The professor informs the class that there will be a test next week. what is the probability that a randomly selected student st
marusya05 [52]

The probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade is: D. 0.80.

<h3>How to calculate the probability?</h3>

In this exercise, you're required to determine the probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade. Thus, we would apply Bayes's theorem.

  • Let S represent studied for.
  • Let B represent a score of B or higher grade

Therefore, we need to find P(S|B):

S|B = \frac{B|S \times S}{B|S \times S\; +\; B|S' \times S'} \\\\S|B = \frac{0.55 \times 0.6}{0.55 \times 0.6 \;+ \;0.2 \times 0.4}\\\\S|B =\frac{0.33}{0.33 + 0.08} \\\\S|B =\frac{0.33}{0.41}

S|B = 0.80.

<u>Complete Question:</u>

At the beginning of the semester, a professor tells students that if they study for the tests, then there is a 55% chance they will get a B or higher on the tests. If they do not study, there is a 20% chance that they will get a B or higher on the tests. The professor knows from prior surveys that 60% of students study for the tests. The probabilities are displayed in the tree diagram.

What are the three components of personality, and how does personality develop in relation to each?.
Mumz [18]

Answer:

He proposed three components to our personality: the id, ego, and superego. The job of the ego is to balance the sexual and aggressive drives of the id with the moral ideal of the superego. Freud also said that personality develops through a series of psychosexual stages.

Natasha_Volkova [10]

Difference between the mean of the data, including the outlier and excluding the outlier is;

B: 0.93

<h3>Mean average</h3>

Her time in minutes for the given months are;

  • January = 41.55 minutes
  • July = 36. 38 minutes
  • Feb = 42.51 minutes
  • Aug = 38.48 minutes
  • Mar = 43. 01 minutes
  • Sept = 41.87 minutes
  • Apr = 39. 76 minutes
  • Oct = 51.32 minutes
  • May = 37. 32 minutes
  • Nov = 42.59 minutes
  • June = 35.28 minutes
  • Dec = 43.71 minutes

Looking at all the numbers, they largely range from 36 to 44 which means that the outlier is 51.32

Total number of minutes with outlier = 493.78 minutes

Number of months = 12

Thus;

Mean with outlier = 493.78/12

Mean with outlier = 41.15 minutes

Mean without outlier = (493.78 - 51.32)/(12 - 1)

Mean without outlier = 40.22 minutes

Thus;

Difference in both means = 41.15 - 40.22

Difference = 0.93
