Luda [366]3 years ago
4 0

Answer:

Correct (1,9), (2,14)

Incorrect (1,8),(2,13)

Step-by-step explanation:

It is simple.

To find the correct values plug a x value.

For Example;

X=1

y=5(1)+4

y=5+4

y=9

so your X value is 1 and your Y value is 9

To solve for the incorrect values

Find the correct values and subtract 1 form the Y value.

The fill weight of a certain brand of adult cereal is normally distributed with a mean of 920 grams and a standard deviation of
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
