Answer:
Assuming order does not matter, the probability of selecting all midsize cars is 0.000277373, or
.
Step-by-step explanation:
First, we must find the n(Total arrangements of selections)=(8+15)C6
n(Total arrangements of selections)=23C6
n(Total arrangements of selections)=100,947
Second, we must find the n(Arrangements where all are midsize cars)=8C6
n(Arrangements where all are midsize cars)=28
To find the probability of selecting all midsize cars, we divide the n(Arrangements where all are midsize cars) by the n(Total arrangements of selections):
P(All midsize cars)= ![\frac{28}{100,947}](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B100%2C947%7D)
P(All midsize cars)=
=0.000277373.
Answer:
(x - 3/5) (x + 4/3)
Step-by-step explanation:
Assuming that the equation is 15x^2 and not 15 x 2, the problem proceeds as so:
Using the x method, multiply 15 by -12 and place that at the top of the x, 11 being placed at the bottom. In the x method, whatever two numbers multiply to produce the top number and add to give the bottom one are your factors.
Placing -180 at the top and 11 on the bottom, you get the numbers -9 and positive 20.
Setting up the first binomials as (x - 9) and (x +20), divide both constants by 15 as the original coefficient is not 1. This gives you 9/15 and 20/15 which simplify to the answers 3/5 and 4/3.
Answer: For these 1,151 residents in 2010, we are 95% confident that the average number of days of "not good" mental health is between 3.40 and 4.24 days.
Step-by-step explanation: The survey 95% confidence interval is (3.4,4.24) days in a population of 1,151. What it means is General Social Survey is 95% confident the true mean of days residents are with mental health "not good" is between 3.4 days and 4.24 days.
