Parallel lines have the same gradient.
The equations are either in the form y = mx+b (m is the gradient)
or in general form ax + by + c = 0 (-a/b)
The gradient of y = 2x - 4 is 2.
The answer is B (gradient = -4/-2 = 2)
Answer:
207400%
Step-by-step explanation:
Look at the decimal number 2074 as 2074 out of one. Furthermore, percent means per hundred. So the task is to convert 2074 out of one to 2074 out of one hundred.
The equation to solve the problem is displayed below where x is the 2074 as a percentage.
2074
/1
=
x
/100
Please mark brainliest if correct and have a blessed day!
We solve the equation for x above by first multiplying each side by one and then multiplying each side by one hundred. Thus, the answer to 2074 as a percentage is:
207400%
Using the hypergeometric distribution, it is found that there is a 0.0065 = 0.65% probability that both David and Valerie get picked for the Tahitian dance lesson.
The people are chosen without replacement from the sample, hence the <em>hypergeometric distribution </em>is used to solve this question.
<h3>What is the
hypergeometric distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- N is the size of the population.
- n is the size of the sample.
- k is the total number of desired outcomes.
In this problem:
- There is a total of 18 people, hence
.
- 2 people will be chosen, hence
.
- David and Valerie corresponds to 2 people, hence
.
The probability that both get picked is P(X = 2), hence:


0.0065 = 0.65% probability that both David and Valerie get picked for the Tahitian dance lesson.

Not a 100% positive this is the answer but i think it is 2.5
got this by dividing 30 by 12 and got 2.5
The answer is
D.(n+3)!
We just need to simplify the expression
(n+4)!/(n+4) =(n+3)! * (n+4)/(n+4)
(n+4)!/(n+4) = (n+3)! * 1
(n+4)!/(n+4) = (n+3)!
