The fill weight of a certain brand of adult cereal is normally distributed with a mean of 910 grams and a standard deviation of 5 grams.

If we select one box of cereal at random from this population, what is the probability that it will weigh less than 900 grams?
0.0228 T/F

p = 0.02275

Step-by-step explanation:

Given

μ = 910 g

σ = 5 g

x = 900 g

We can use the equation

Z = (x - μ)/σ   ⇒    Z = (900 g - 910 g)/5 g = - 2

using the table (with Z = -2) we get

p = 0.02275

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
