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

The point (2,-4) is on the line given by which equation below?

densk [106]

Answer: (A) y=-2x

Step-by-step explanation:

Lets plug in the point (2,-4) for each equation.

-4=-2(2) this is correct

-4=2*2

-4=4 This cannot be true

-4=-2+3 =-4=1 This is false

Lastly, -4=2-4 this is false because -4 can't equal to -2.

So, A is the answer
