Answer:
20%
Step-by-step explanation:
If you see they say that the number decreased is 10% each and they say it two times. we could see that the missing number is as big as the length of two 10% together, so if you add them two you get 20%.
(a) total profit
=11000*24%+14000*15%
=2640+2100
=$4740
(b) percent profit
=4740/(11000+14000)
= 0.1895
=18.96%
NOTE: I ACCIDENTALLY clicked one star. That DOES NOT count as a real rating, and this DOES NOT mean my answer is bad!
Answer:
Commutative Property of Addition
Step-by-step explanation:
Step 2: -4 + (-37) + (-3) + (-47) + 7
Step 3: -4 + (-37) + (-47) + (-3) + 7
Because the order was changed, it is the Commutative Property.
Answer:
BC=5
Step-by-step explanation:
4/10=x/x+3
4(x+3)=10x
4x+12=10x
subtract 4x from each side
6x=12
divide both sides by 6
6x/6=12/6
x=2
BC=x+3
substitute for x
BC=2+3
BC=5
Answer:
1.) 107 observations
2.) the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths
3.) A. sample size is too small for the central limit theorem to apply.
4.) The test requires that the sample mean is normally distributed; this requires that either the population distribution is Normal or the sample size exceeds 30.
5.) a Type I error
Step-by-step explanation:
n = [(Zcritical * σ) ÷ E]²
n = sample size
Zcritical at 99% = 2.58
E = error margin = 0.5
Standard deviation, σ = 2
n = [(2.58 * 2) ÷ 0.5]²
n = [5.16 ÷ 0.5]²
n = (10.32)²
n = 106.5024
n = 107 observations
B.) The thought or decision that the best veterinary hospital is likely to see the most severe cases with larger number of enteroliths will introduce a bias in the study.
C.) For central limit theorem ; sample size must be considerably large ; at least sample size, n ≥ 30
D.) Distribution must be normal it approximately normal, obeying the central limit theorem ; sample size must be considerably large ; at least sample size, n ≥ 30
