Ответ:
The probability that it will weigh more than 904 grams = 0.9452
Step-by-step explanation:
Given -
Mean
= 920 grams
Standard deviation
=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 =
=
Putting ![( Z = \frac{X - \nu }{\sigma } )](/tpl/images/0590/1299/e19f2.png)
=
Using Z table
= 1 - .0548
= 0.9452
Ответ:
y = 2x - 3
Step-by-step explanation:
Written in the standard form, y = mx + b is a straight line with slope, m, and y-intercept, b.
y = mx + b
slope, m = 2 and y-intercept, b, = -3
y = 2x - 3
