Answer:
+ 
i
Step-by-step explanation:
Expressing the complex numbers in coordinate form
3 + 8i → (3, 8 )
2 - i → (2, - 1 )
To find the midpoint use the midpoint formula
midpoint = [0.5(3 + 2), 0.5(8 - 1) ] = [0.5(5), 0.5(7) ] = ( , )
and (, ) = + i
Answer:
A.3/7
Step-by-step explanation:
1/2 - 1/14
We need to get a common denominator of 14
1/2 * 7/7 = 7/14
7/14 - 1/14 = 6/14
We can simplify by dividing the top and bottom by 2
3/7
Answer:
The probability that a randomly chosen tree is greater than 140 inches is 0.0228.
Step-by-step explanation:
Given : Cherry trees in a certain orchard have heights that are normally distributed with 
inches and 
inches.
To find : What is the probability that a randomly chosen tree is greater than 140 inches?
Solution :
Mean - inches
Standard deviation - inches
The z-score formula is given by, 
Now,
The Z-score value we get is from the Z-table,
Therefore, the probability that a randomly chosen tree is greater than 140 inches is 0.0228.
Answer:
A. The elements in the domain of f(x) for which g(f(x)) is defined
I just took the test myself. (gºf)(x) can be rewritten as g(f(x)) and the interior function, which is f(x) in this case, is the domain, where x is defined.

Elapsed
Time (seconds) Distance Traveled (feet)
1 6.2
2 12.4
3 18.6
4 24.8
Explanation:
You can check that 6.2 / 1 = 12.4 / 2 = 18.6 / 3 = 24.8 / 4 = 6.2
So, the relationship between the distance traveled and the time elapsed is a constant:
distance traveled / time elapsed = 6.2
n / f = 6.2
=> n = 6.2 f
Answer: n = 6.2 f
