c)  22 points

d)  -11 points

Step-by-step explanation:

a)  20 * 3 = 60 points (all answered correct)

b)   0 point (Minimum score if you don't answer any of the questions)

c)  10 * 3 = 30 points

    (14 - 10)  * -2 = -8 points

Suppose that the probability of having a particular disease is 0.08. Suppose that the probability of testing positive for the di
Paraphin [41]

Answer:

0.5054

Step-by-step explanation:

This is a question on conditional probability.

We solve using Baye's Theorem of conditional probability

From the question

The probability of having a particular disease = 0.08.

The probability of not having a particular disease = 1 - 0.08 = 0.92

The probability of testing positive for the disease is given that a person has the disease = 0.94

The probability of testing positive given that the person does not have the disease = 0.08

Given that a person tests positive for the disease, the probability that they actually have the disease is

= (0.08 × 0.94)/(0.08 × 0.94) + (0.08 × 0.92)

= 0.0752/0.0752 + 0.0736

=0.0752/ 0.1488

= 0.5053763441

≈ Approximately to 4 decimal places = 0.5054

Answer this question showing work. 2b − 7 ≥− 14 + 2b
jeka94

Answer:

No solution

Step-by-step explanation:

This answer has no solution, follow these steps to see how.

First, you add 7 on both sides.

Then you should have 2b > -7 +2b

You see how there is a 2b on both sides? this makes the problem unsolvable.

Say you were to continue though. You would subtract 2b on both sides and end up getting 0 > -7.  Therefore there is no solution.

Answer:

Option(D)

Step-by-step explanation:

Diameter of the Sun (S) = 1.4 × 10⁶ km

Diameter of a planet mars (M) = 7000 km

                                            ≈ 7.0 × 10³ km

Ratio of the diameter of the Sun to the diameter of Mars

= \frac{S}{M}

= \frac{1.4\times 10^{6}}{7.0\times 10^{3}}

= 0.2\times 10^{6-3}

= 0.2\times 10^3

= 2\times 10^2

Option (D) will be the correct option.
