The accounting department analyzes the variance of the weekly unit costs reported by two production departments. A sample of 16

cost reports for each of the two departments shows cost variances of 2.3 and 5.6, respectively. Is this sample sufficient to conclude that the two production departments differ in terms of unit cost variance? Use a = .10.
Calculate the value of the test statistic (to 2 decimals).

every sixth visitor to an animal shelter gets a free animal calendar every twentieth visitor gets a free animal toy. Which visit
Akimi4 [234]
Here we have a case of the least common multipl(lcm) of 6 and 20.
Prime numbers 2,3,5,7,11,13,17,19... (natural numbers greater than 1 that has no positive divisors other than 1 and itself) .
lcm(6,20)= 6 20 | 2
                  3 10 | 3
                  1 10 | 2
                       5 | 5
                       1
2*3*2*5=60 The first one to get both calendar and the animal toy will be 60th.
 
Explenation: First we look for the smallest prime number with wich 6 and 20 can be devided by. That is 2. Next is 3. Since 10 is not divisible by 3, we only copy it. Under the 6 we got 1, wich is our goal. Now we continue to devide 10 by prime numbers till we also get 1. We now multiple all divisors and we get the least common multiple.

Find the measure of angle KMU.​
valina [46]
140 degrees, solve for the interior angle of LMK which can be found by 180-90-50 so now we know this is 40. However we need the other angle( KMU) that is supplemental with it, so 180-40 gives you 140 which is your final answer.


140 degrees
