Answer:
0.31
Step-by-step explanation:
% conservatives = 30 ; voted = 65%
% Liberals = 50 ; voted = 82%
% Independents = 20 ; voted = 50%
If a person in the city is selected at random and it is learned that she did not vote in the last election, what is the probability that she is a liberal
Number that did not vote :
% conservative × (1 - voted) + % Liberals × (1 - voted) + % conservatives × ( 1- voted)
(30% × 0.35) + (50% × 0.18) + (20% × 0.5)
(0.3 × 0.35) + (0.5 × 0.18) + (0.2 × 0.5)
= 0.105 + 0.09 + 0.1 = 0.295
Hence, probability that a person chosen at random did not vote and she's a liberal :
P = liberal who did not vote / total who did not vote
P = (0.5 × 0.18) / 0.295
P = 0.09 / 0.295
= 0.30508
= 0.31
Answer:
$400
Step-by-step explanation:
If Lucy had $300, and at the end of the day she had $700, this means that she made $400.
Answer: 2 2/3
Step-by-step explanation: 5 - 2 1/3 = 2 2/3
2 2/3+2 1/3 = 5
Question
Which expression is equivalent to . Assuming
Answer:
Step-by-step explanation:
Given
Required:
Simplify
To simplify this, we start by splitting each individual function
From laws of indices
SO, the above expression can also be expressed the same way
From laws of indices,
So,
Hence, is equivalent to
For table # 1:
x= 1 * 3.5 = 3.5
x = 2*3.5 = 7
x = 3*3.5 = 10.5
x = 4* 3.5 = 14
For table #2
x=1 * 3 = 3
x =2 * 3 = 6
x = 3*3 = 9
x = 4* 3 = 12
Hence, the data sets show multiplicative relationships:
For data set 1 is 3.5 times x, and in data set 2 y is 3 times x.
