Answer:
Sue played 30 games
Step-by-step explanation:
Probability is typically given as a fraction or percentage where the numerator is the number of desired outcomes and the denominator is the total number of outcomes. Since Sue's won 12 games and estimated the probability to be 0.4 or 4/10, you can set up a proportion, or equivalent ratios, to solve for the number of games she played:
Cross multiply: 4x = 120
Divide by 4: 4x/4 = 120/4
Solve for 'x': x = 30 games
Answer:
1. Yes
2. Yes
Step-by-step explanation:
A monomial is an algebraic expression consisting of one term. So, 29 is a monomial.
has only one term. So,
is a monomial.
Answer:
a) mean = 1.42 occupant/car
b) standard deviation = 0.89 occupants
c) median = 1 occupant
d) The proportion of cars had more than the mean number of occupants is 0.24
e) The proportion of cars with the number of occupants more than one
standard deviation greater than the mean is 0.11
f) The proportion of cars with the number of occupants within one standard
deviation of the mean is 0.89
