Answer:
w=15
Step-by-step explanation:
The way I found the answer is dividing 120 by 8 which equaled 15 and I made sure it was correct as I multiplied 8 by 15 and the answer was 120.
Answer: the probability that the weight will be less than 4866 grams is 0.9861
Step-by-step explanation:
Since the weights of newborn baby boys born at a local hospital are believed to have a normal distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = weights of newborn baby boys.
µ = mean weight
σ = standard deviation
From the information given,
µ = 3571 grams
σ = 589 grams
The probability that the weight will be less than 4866 grams is expressed as
P(x < 4866)
For x = 4866,
z = (4866 - 3571)/589 = 2.2
Looking at the normal distribution table, the probability corresponding to the z score is 0.9861
A. They are parallel because when you solve for y they have the same slope
I believe
Father= 40
Son=10
I researched this and it’s really confusing. I’m not sure how to explain it to you, but I might be able to send you screenshots of what I’ve seen if you would like. If this is wrong please let me know. I hope this helps!!
