Step-by-step explanation:
cot x / (1 + csc x)
Multiply by conjugate:
cot x / (1 + csc x) × (1 − csc x) / (1 − csc x)
Distribute the denominator:
cot x (1 − csc x) / (1 − csc²x)
Use Pythagorean identity:
cot x (1 − csc x) / (-cot²x)
Divide:
(csc x − 1) / cot x
Answer:
x = 335 - (6 * v)
Step-by-step explanation:
In order to calculate the value remaining, we need to first multiply the daily cost of each visit by the number of visits made to the gym which is represented by the variable (v). Once we have this cost of all the days then we subtract this amount from the current account balance in order to get the new remaining balance which is represented by x.
x = 335 - (6 * v)
This is the distributive property; you're taking the 10 and giving it, or distributing it, to the 4 and the 3. the best way to remember it on sight is just thinking about what "distributing" means.

Answer:
The provided statement is not a binomial experiment.
Step-by-step explanation:
Four conditions of a binomial experiment:
There should be fixed number of trials
Each trial is independent with respect to the others
The maximum possible outcomes are two
The probability of each outcome remains constant.
For example:
Binomial distribution: Asking 200 people if they ever visit to new york.
Not Binomial distribution: Asking 200 people how much they earn in a week.
Now, observe the provided information:
We need to determine that, asking 100 people which brand of car they drive is a binomial experiment or not.
Clearly it is not a binomial experiment because the maximum possible outcomes are not two.
Therefore, the provided statement is not a binomial experiment.
