Answer: 0.74
Step-by-step explanation:
A= "The person is sick
"
B= "The test gives a positive result"
P(A)=0.03
P(B|A)=0.92
P(B|A')=0.01
P(A')=1-P(A)=1-0.03=0.97
P(B)=P(B|A)P(A)+P(B|A')P(A')=0.92*0.03+0.01*0.97=0.0373
Based in Bayes Rule
P(A|B)=P(B|A)P(A)/P(B)=0.92*0.03/0.0373=0.74
In order to find the answer of the given problem above, we need to make the solution below:
Given: 2/3 of an hour = practice each day
2/3 of an hour is equivalent to 40 minutes
And per week, there are 7 days. So we will multiply 40 minutes by 7, and the result is 280 minutes. Since there are 60 minutes in an hour, we divide 280 by 60 and we get 4.67 hours. Therefore, each week, you would get 4.67 hours of practice on playing a musical instrument.
If you spent 1/2 at the theater, and 1/4 at the arcade then you spent 3/4 of your money leaving you with 1/4 left. multiply the amount of money you have left ($17.50), by 4. You originally had $70. hope this helps!
-15 is the answer. the ( . ) represents multiplying
Answer:
The domain is {0.5, 1, 1.5, 2}
The range is {1.9, 3.8, 5.7, 7.6}
Step-by-step explanation:
The cost, y is in dollars, and x in pounds of almonds is shown in the table.
x (pounds) y ($)
0.5 1.9
1 3.80
1.5 5.70
2 7.60
The grocery store sells almond at $3.80 per pound, the relation between y and x is given by the function:
y = 3.8x
The x values are the independent variables and they serve as the input of the function while the y values are the dependent variables (dependent on x) and the serve as the output of the function.
The domain consist of input values which is the x values. The domain is {0.5, 1, 1.5, 2}
The range consists of all output values i.e the y values. The range is {1.9, 3.8, 5.7, 7.6}
