The next 18 days because your trying to see how many days it is until he does BOTH
First change the fraction to percent.
3/4 = 60%
Then change the percent to the decimal.
60% = 0.75
Now multiply it.
<span>0.75 x 60% = 45

45 is the answer.
Answer:
b. It will decrease by a factor of 2
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The lower end of the interval is given by:
The upper end of the interval is given by:
The length of the interval is the subtraction of the upper end by the lower end, so it is:
This means that the length is inverse proportional to the square root of the size of the sample.
So, if the sample size is multiplied by 4, the length of the interval is going to decrease by a factor of 2.
- I) the probability that the person is female is 8.33%.
- II) the probability that the person has a risk factor heterosexual contact is 6.40%.
- III) the probability that the person is female or has a risk factor of IV drug user is 23.47%.
- IV) the probability that the person is female and has a risk factor of homosexual is 0%.
- V) the probability that the person is male and has a risk factor of IV drug user is 15.13%.
- VI) the probability that the person is female given that the person got the disease from heterosexual contact is 69.38%.
Given the data mentioned in the table, the following calculations must be performed to obtain the requested probabilities:
I.-
(0 + 70 + 136 + 49) / (2,146 + 463 + 60 + 135 + 0 + 70 + 136 + 49) = X
255/3059 = X
0.0833 = X
II.-
196/3059 = X
0.0640 = X
III.-
(255 + 463) / 3059 = X
718/3059 = X
0.2347 = X
IV.-
0/3059 = X
0 = X
V.-
463/3059 = X
0.1513 = X
VI.-
136/196 = X
0.6938 = X
Therefore, I) the probability that the person is female is 8.33%, II) the probability that the person has a risk factor heterosexual contact is 6.40%, III) the probability that the person is female or has a risk factor of IV drug user is 23.47%, IV) the probability that the person is female and has a risk factor of homosexual is 0%, V) the probability that the person is male and has a risk factor of IV drug user is 15.13%, and VI) the probability that the person is female given that the person got the disease from heterosexual contact is 69.38%.

Answer:
-4/5
Step-by-step explanation:
Two points that I see are not decimals are (-3,1) and (2,-3)
y1-y2/x1-x2= slope
-3-1/2-(-3)= -4/5
