Answer: the probability that the person is between 65 and 69 inches is 0.54
Step-by-step explanation:
Since the height for Asian adult males is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = height for Asian adult males.
µ = mean height
σ = standard deviation
From the information given,
µ = 66 inches
σ = 2.5 inches
We want to find the probability that the person is between 65 and 69 inches. It is expressed as
P(65 ≤ x ≤ 69)
For x = 65
z = (65 - 66)/2.5 = - 0.4
Looking at the normal distribution table, the probability corresponding to the z score is 0.34
For x = 69
z = (69 - 66)/2.5 = 1.2
Looking at the normal distribution table, the probability corresponding to the z score is 0.88
Therefore,
P(65 ≤ x ≤ 69) = 0.88 - 0.34 = 0.54
Cost of both the Company A & B is $200 we can use any company . Other factors which is seen is that which company give better quality of mulch , buy from there ! Also , for an instance buying from Company B will be good as you can buy much more mulch with rate of $1.50 , Prefer Company B when you need to buy mulch more than 100 cubic feet .
<u>Step-by-step explanation:</u>
Here we have , A group of students wants to put mulch in some flower beds near their school. It will take 100 cubic feet to mulch the entire flower bed. Company A sells bags of mulch for $2 per cubic foot. Company B will deliver a truckload at $1.50 per cubic foot, but charges a $50 delivery fee. We need to Write an equation to model each situation. Then decide which company should be used. Are there other factors to consider other than cost . Let's find out:
There is 100 cubic feet to mulch the entire flower bed .
- Company A sells bags of mulch for $2 per cubic foot.
According to this , total cost for 100 cubic feet by Company A sells is :
⇒
⇒
- Company B will deliver a truckload at $1.50 per cubic foot, but charges a $50 delivery fee
According to this , total cost for 100 cubic feet by Company B sells with $50 as delivery charge is :
⇒
⇒
Since, Cost of both the Company A & B is $200 we can use any company . Other factors which is seen is that which company give better quality of mulch , buy from there ! Also , for an instance buying from Company B will be good as you can buy much more mulch with rate of $1.50 , Prefer Company B when you need to buy mulch more than 100 cubic feet .
