The mean incubation time of fertilized eggs is 23 days. Suppose the incubation times are approximately normally distributed with

Anna007 [38]

Answer: the incubation time that separates the bottom 2.5% from the rest of the incubation times is 24.96 days.

Step-by-step explanation:

Suppose the incubation times are approximately normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = incubation times.

µ = mean time

σ = standard deviation

From the information given,

µ = 23 days

σ = 1 day

The probability value for the incubation time that separates the bottom 2.5% from the rest of the incubation times would be (1 - 2.5/100) = (1 - 0.025) = 0.975

Looking at the normal distribution table, the z score corresponding to the probability value is 1.96

Therefore,

1.96 = (x - 23)/1

x = 1.96 + 23

x = 24.96

Mr.Johnson imported some cartons of noodles.There were 28 packages of in each carton.he then sold 10 of noodles for $5 if he rec

iragen [17]

Answer:

The total number of cartons did he sale is 20 .

Step-by-step explanation:

Given as :

The total number package in each carton = 28

The total amount received after sale = $ 280

The cost of 10 noodles = $ 5

Let the total number of cartoon sale = x

According to question

∵ The number of noodles costing $5 is 10

so,The number of noodles costing $1 is $\frac{10}{5}$ = 2

∴ The number of noodles costing $280 = 2 × 280 = 560

Now, since there are 28 packages in 1 carton

So . the number of carton did he sale = $\dfrac{\textrm total number of noodles}{\textrm total package in each cartoon}$

Or, The number of carton did he sale = $\frac{560}{28}$ = 20

Hence The total number of cartons did he sale is 20 . Answer
