√x+3 = 2
First we should simplify the equation by squaring both sides:
x + 3 = 4
Isolate x by taking 3 off both sides:
x = 1
We should ALWAYS check that our answer is correct after working out the value of x. We can do this by substituting x into the original equation:
√x + 3 = 2
Turns into:
√1 + 3 = 2
Which turns into:
√4 = 2
Which is true, therefore we can confirm:
x = 1
Answer:
Discrete(b,c and d)
Continuous (a and e)
Step-by-step explanation:
<u>Discrete</u>
Discrete Random variables are variables that can only take on integer values. Therefore the following are discrete variables.
b. The number of fish caught during a fishing tournament. e.g. 6 fishes
c. The number of statistics students now reading a book. e.g. 12 Students
d. The number of textbook authors now sitting at a computer. e.g. 9 Authors
<u>Continuous</u>
Continuous random variables can take on an uncountable number of values.
a. The time it takes for a light bulb to burn out. e.g.178.897 seconds
e. The height of a randomly selected giraffe. e,g 16.67 feet
It is a mental health disorder characterized by sad mood
