The Department of Economic and Community Development (DECD) reported that in 2009 the average number of new jobs created per county was 450 (the only information that you know from DECD). Doing a project in your international economics class, you want to determine whether there has been a decrease in the average number of jobs created, and you collect information about 10 countries. To conduct the hypothesis test, what distribution would you use to calculate the critical value and the p-value

the answer is b

answer: 12/52

step-by-step explanation: my reasoning is that there are 12 face cards in a deck and a total of 52 cards in all.

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180

step-by-step explanation:

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
