gulaghasi [49]

Answer:

The probability that it will weigh more than 904 grams = 0.9452

Step-by-step explanation:

Given -

Mean $(\nu )$ = 920 grams

Standard deviation $(\sigma )$ =10

Let X be the weight of a certain brand of adult cereal

if we select one box of cereal at random from this population

The probability that it will weigh more than 904 grams =

$P(X> 304)$ = $P(\frac{X - \nu }{\sigma }> \frac{904 - 920}{10})$

= $P(Z> -1.6)$ Putting $( Z = \frac{X - \nu }{\sigma } )$

= $1- P(Z< -1.6)$ Using Z table

= 1 - .0548

= 0.9452

If x is an even number, the function f(x) = 2x − 1 gives an odd number. Identify the set of odd numbers corresponding to this se

Alex787 [66]

X = {0, 2, 4, 6, 8}.

=> f(x) = 2x - 1

x                  f(x) = 2x - 1

0                   2*0 - 1 = - 1

2                   2*2 - 1 = 3

4                   2*4 - 1 = 7

6                   2*6 - 1 = 11

8                   2*8 - 1 = 15

Answer: {-1, 3, 7, 11, 15}
