Answer:
The product is 25
Step-by-step explanation:
we know that
The complex number z1 is equal to
z1=(-4-3i)
we know that
To find the complex conjugate of (-4 - 3i) we change the sign of the imaginary part
so
The conjugate is equal to (-4+3i)
therefore
Answer:
The probability of being older than 25 years and having a hemoglobin level above 11 is 19.58%. Since the question is referring to persons older than 25 years, we'll include all the data above 25 years.
So under 25-35 years old is 44 and under 35 years old is 40.
44 + 40 = 84
84 / 429 = 0.1958 or 19.58%
The probability of having a hemoglobin level above 11 is 35.66%. We would just get the ratio of 153 people who have hemoglobin level above 11 over the population of 429. 153 / 429 = 0.356643 or 35.66%
Being older than 25 years and having a hemoglobin level above 11 is not dependent on each other. Since the data is inversely proportional. The older the person gets, the lesser the number of people having hemoglobin level above 11 (A) 19.58%.
I hope this helps!
Answer:
<h2>The value of this expression is <u>
A: 3</u></h2>
Step-by-step explanation:
Answer:
You would plot the following points, remembering that they’re in the form (x,y) = (time, height):
(1,35) (2,60) (3,92) (4,120) (5,175)
The ordered pairs would be closer together, and there would be 4 times more of them if you were to measure every 15 seconds instead. You would have a line with more points that were closer together.
Answer:
The pipe A will fill the pool in 2.25 hours and the pipe B will fill the pool in 1.75 hours.
Step-by-step explanation:
Pipe A alone can fill the pool in 4 hours.
So, in 1 hour it fills 
part of the pool.
and in 30 minutea it fills 
part of the pool.
If the pipe B is opened after 30 minutes the pipe A opened.
So, 
part of the pool is filled by both the pipe.
Again, pipe B alone fills the pool in 4 hours.
Hence, if both the pipes are open then they will fill in one hour 
part of the pool.
So, the remaining 
part of the pool will be filled by both the pipe in 
hours i.e. 1.75 hours.
Therefore pipe A will fill the pool in (0.5 + 1.75) =2.25 hours and pipe B will fill the pool in 1.75 hours. (Answer)
