Answer:
D
Step-by-step explanation:
First find the probability using the normal distirbution formula X - mean / standard deviation for both X = 350 and X =450 to get the values -1 and 1 so thi(-1) < P(Z) < thi(1) if you are familiar with normal distirbution table values you will calculate that the overall probability is 0.6827
knowing this we can roughly expect how much emergencies are in the response times by 0.6827 x 144 = 98
The remainder is non-zero, so 
is not a factor of 
(or whatever the given polynomial is supposed to be)
Answer:
x=(5+i*sqrt(35))/2, (5-i*sqrt(35))/2
Step-by-step explanation:
Use the quadratic formula with the following values.
a = 1
b = -5
c = 15
Substitute and simplify.
(5+-sqrt((-5)^2-4*(1*15)))/2*1
x = (5+-i*sqrt(35))/2
When you get a negative number inside the square root, remember that you can pull out i to make the number inside positive.
Answer:
-2
Step-by-step explanation:
<em>Since,</em>
<em>it given that</em>
<em>x = -3</em>
<em>y = 4</em>
<em>and the equation is:</em>
<em>2x + y = ?</em>
<em />
<em>Thus we can substitute:</em>
<em>2(-3) + 4 = ?</em>
<em>-6 + 4 = -2</em>
<em>Hence,</em>
<em>? = -2</em>

The experimental probability is C. 17%.
17% is derived from the following solution.
14/84 = 0.1666
0.1666 * 100% = 16.66% or 17%
This is based on the result of the experiment conducted.
The theoretical probability of A is 20%.
1/5 = 0.20
0.20 x 100% = 20%
A is only one event out of 5 letters.
