48=4% loaded on truck and they have 96% left to load
So set up a proportion and it should look like this
48 over x = 4 over 100
48/x=4/100
Do cross multiplication 100×48= 4,800÷ 4 = 1,200 total on truck
Answer:
Let x = number of units produced per hour before the line was modified , y = number of units produced per hour after the line was modified.
The null and alternative hypotheses are :
H0: μbefore = μafter
H1: μbefore ≠ μafter
Step 1: . Calculate the difference (D = y − x) between the two observations on each pair.
See attachment for (D=y-x)
step 2: Calculate ∑D and ∑D2
From table we get ∑D = -10 & ∑D2 = 72
Step 3: Put all the value in test statistic "t"
t = D/√nD^2-D^2/n - 1
t =-10/√6.72-(-10)^2/6-1
t= -10√66.4
= -10/8.1486
= -1.227
Step 4: Compare tcal and ttab
At α = 0.05
t0.05 for 5 d.f. = 3.1634 (two tail test)
Hence | tcal | < t0.05
So, we accept the hypothesis.
So we conclude that the modified (after) layout has not increased worker productivity at 5% level of significance.
Answer:
The angle of DC is 130°.
Step-by-step explanation:
Given tha total angle in a centre(O) of circle, is 360. So in order to find ∠DOC, you have to subtract 85° and 145° from 360° :
∠COD = 360° - ∠COE - ∠DOE
= 360° - 85° - 145°
= 130°
Answer:
answer is 1=2=3244515/15/152/51//51/1=12900 is the answer all you need to do is get 1700k - 10000 and yes its negative.
