As far as i can tell it would just be y+2?
Answer: 8:1, 16:2, 24:3,40:5
Step-by-step explanation:
Answer:
3.4 kg
0.06 kg
Step-by-step explanation:
Given that:
Birthweight follows a normal distribution :
Mean weighf (m) = 3.4 kg
Standard deviation (σ) = 0.6 kg
Sample size (n) = 100 new born babies
calculate the sample mean birth weight for each sample. Calculate the mean and standard deviation of the sampling distribution
The sample mean birth weight = population mean birth weight for a normal distribution according to the central Limit theorem.
Hence, sample mean birth weight = 3.4kg
Standard deviation of sampling distribution = standard error = σ/√n
0.6 / √100
= 0.6 / 10
= 0.06 kg
D = devaugn's age
s = sidney's age
so, we know Devaugh's age is twice as Sydneys, so d = 2*s or 2s
and we know their sum is 66
or d + s = 66
since d = 2s, thus
(2s) + s = 66 <--- solve for "s" to see Sidney's age
what about Devaugn's? well d = 2s
Answer:
The answer would be 14
Step-by-step explanation:
you just divide 28,00 by 200 and that gives you 14
