Assume the weight of Valencia oranges is normally distributed with a mean 9 oz and standard deviation 2 oz. What is the probabil

Natasha_Volkova [10]

Answer:

0.99379

Step-by-step explanation:

The first thing to do here is to calculate the z-score

mathematically;

z-score = x-mean/SD/√(n)

From the question x = 9.5 ,

mean = 9, SD = 2 and n = 100

Plugging the values we have;

z-score = (9.5-9)/2/√(100) = 0.5/2/10 = 0.5/0.2 = 2.5

So the probability we want to calculate is;

P(z<2.5)

We use the standard table for this

and that equals 0.99379

Question attached below

tamaranim1 [39]

Answer:

B . $f(x+h)=\frac{x+h}{1+x+h}$

Step-by-step explanation:

Given function is:

$f(x)=\frac{x}{1+x}$

Sall h is used to denote minor change in function. The value of the new function f(x+h) will be calculated by putting x+h in place of x in the function.

So putting x+h in place of x

$f(x+h)= \frac{x+h}{1+(x+h)}\\=\frac{x+h}{1+x+h}$

So, option B is the correct answer ..
