Answer:
<u>670 numbers</u>
Step-by-step explanation:
T1=1*3-2
T2=2*3-2
T3=3*3-2
...............
<u>Tn=n*3-2</u>
n*3-2=2008
n*3=2010
n=2010:3
n=670 (numbers)
Answer: -5
Step-by-step explanation: The common difference is the same number we are adding each time to get from one term to the next.
In this sequence, we are adding -5 each time
so our common difference is -5.
Answer: 0.8461
Step-by-step explanation:
Given : 
Let x be the random variable that represents the cost for the hospital emergency room visit.
We assume that cost for the hospital emergency room visit is normally distributed .
z-score for x=1000 ,
Using z-value table , we have
P-value =P(x>1000)=P(z>-1.02)=1-P(z≤ -1.02)=1-0.1538642
=0.8461358≈0.8461 [Rounded nearest 4 decimal places]
Hence, the probability that the cost will be more than $1000 = 0.8461
X = 4 and Y = 9. I did a complicated way of doing it so if u copy it it would look weird
