Answers

Answer:

2

Step-by-step explanation:

$ 1.55 + $1.65 = $3.11

the budget is $7.95

$7.95 ÷ $3.11 = 2.5 but since you can't get half a milk it's 2

In a particular country, 3% of the population is HIV positive. A test for HIV correctly
diagnoses 95% of those who have the condition, but incorrectly diagnoses 4% of those
who are not HIV positive as being HIV positive. A patient obtains a positive test result,
apparently indicating the presence of HIV. Determine the probability that the patient
really is HIV positive.

Answers

Using conditional probability, it is found that there is a 0.4235 = 42.35% probability that the patient  really is HIV positive.

Conditional Probability

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened. [tex]P(A \cap B)[/tex] is the probability of both A and B happening. P(A) is the probability of A happening

In this problem:

Event A: positive test.Event B: HIV positive.

The percentages involving a positive test are:

95% of 3%(positive)4% of 100 - 3 = 97%(not positive).

Hence:

[tex]P(A) = 0.95(0.03) + 0.04(0.97) = 0.0673[/tex]

The probability of both having a positive test and being HIV positive is:

[tex]P(A \cap B) = 0.95(0.03)[/tex]

Then, the conditional probability is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.95(0.03)}{0.0673} = 0.4235[/tex]

0.4235 = 42.35% probability that the patient  really is HIV positive.

[tex]W = 23.7°[/tex]

Step-by-step explanation:

The formula given is the statement of Snell's law of refraction. We are given the following:

[tex]I_a = 1.0003[/tex]

[tex]I_w = 1.3[/tex]

[tex]A = 31.5°[/tex]

So we need to find the angle of refraction W. Starting with Snell's law,

[tex]\dfrac{I_w}{I_a} = \dfrac{\sin A}{\sin W} \Rightarrow \sin W = \left(\dfrac{I_a}{I_w}\right)\sin A[/tex]

Plugging in the given values, we get

[tex]\sin W = \left(\dfrac{1.0003}{1.3}\right)\sin{31.5°} = 0.402[/tex]

Solving for the angle W, we then get

[tex]W = \sin^{-1}(0.402) = 23.7°[/tex]

6 is 100 times ____.
0.06 is 10 times ____.
60 is 1/100 of ____.

Answers

Answer:

6 is 100 times 0.06  

0.06 is 10 times 0.006  

60 is 1/100 of 6,000

Step-by-step explanation:

Since 6/100 is equal to 0.06, we can say that 6 is the result of multiplying 0.06 by one hundred (0.06 x 100 = 6).  

On the other hand, since 0.06 / 10 is equal to 0.006, it is correct to say that 0.006 x 10 is equal to 0.06 (0.006 x 10 = 0.06).  

Finally, 60 is one hundredth of 6000, since multiplying 60 x 100 the result is 6,000 (6,000 / 100 = 60).

hope this really helped!!

mark me brainliest :D

The complete sentences are:

6 is 100 times 0.06 .

0.06 is 10 times 0.006.

60 is 1/100 of 6,000.

"6 is 100 times greater than 0.06":

This means that if you multiply 0.06 by 100, you get 6.

So, 6 is indeed 100 times larger than 0.06.

"0.06 is 10 times greater than 0.006":

In this case, if you multiply 0.006 by 10, you get 0.06.

Thus, 0.06 is 10 times larger than 0.006.

"60 is 1/100 of 6,000":

This means that if you divide 6,000 by 100, you get 60.

So, 60 is a hundredth (1/100) of 6,000.

Hence, 6 is 100 times 0.06  

0.06 is 10 times 0.006  

60 is 1/100 of 6,000
