(n+11)(n-4) is your answer
Answer:
Step-by-step explanation:
I don't know where you are in your class, or even what chapter you are in, but I solved this using a right triangle.
We don't need to know the angles, just the sides.
c is the hypotenuse, the line at a tilt
b is the adjacent line, directly below c
a is the opposite line
c = 13
a= 12
b = ?
In order to find b, we use the Pythagorean Theorem, , but we need to rearrange the problem to where we are solving for b instead of c,
So, b = 17.69
Now, we need to evaluate each of the trig. functions:
So, there is your answers, hope that is what you are looking for.
Answer: 0.0241
Step-by-step explanation:
The formula we use to find the margin of error :
, where z* = Critical value , n= Sample size and p = Sample proportion.
As per given , we have
n= 2400
Sample proportion of subjects showed improvement from the treatment:
Critical value for 99% confidence = z*= 2.576 (By z-table)
Now , the margin of error for the 99% confidence interval used to estimate the population proportion. :
[Round to the four decimal places]
Hence, the margin of error for the 99% confidence interval used to estimate the population proportion. =0.0241
The answer to this question would b:
=5x−9
T could be located at 15 because 5 plus 15 equals 20
