According to a center for disease​ control, the probability that a randomly selected person has hearing problems is 0.1530.153.

The probability that a randomly selected person has vision problems is 0.0830.083. Can we compute the probability of randomly selecting a person who has hearing problems or vision problems by adding these​ probabilities? Why or why​ not?
(A) No, because hearing problems and vision problems are events that are too similar to one another.

(B) No, because hearing and vision problems are not mutually exclusive. So, some people have both hearing and vision problems. These people would be included twice in the probability.

(C) Yes, because this is an application of the Addition Rule for Disjoint Events.

(D) Yes, because hearing and vision are two different senses, and therefore, they are two unique problems.

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Probability that a randomly selected person has hearing problems = 0.153

Probability that a randomly selected person has vision problems = 0.083

We need to check whether probability of randomly selecting a person who has hearing problems or vision problems by adding these probabilities.

Since they are disjoint events as the same person does not have both the problems at the same time.

So, we can calculate by adding both.

P(H∪V)=0.153+0.083=0.236

Hence, Option 'c' is correct.

Point T is located at (6, –2) and point S is located at (1, 13). What are the coordinates of the point that is `\frac{4}{5}` of
vlabodo [156]

The coordinates of the point that is 4/5 of the way from T to S is (2,10)

<h3>How to determine the coordinates of the point?</h3>

The given parameters are:

T = (6,-2)

S = (1,13)

Location = 4/5

The location 4/5 means

Ratio, m : n = 4 : 1

The coordinate is then calculated as:

(x,y) = \frac{1}{m +n} * (mx_2 + nx_1,my_2 + ny_1)

This gives

(x,y) = \frac{1}{4 +1} * (4 * 1 + 1 * 6 , 4 * 13 + 1  * -2)

Evaluate

(x,y) = \frac{1}{5} * (10 , 50)

This gives

(x,y) =  (2,10)

Hence, the coordinates of the point that is 4/5 of the way from T to S is (2,10)

Answer:

  choices A and F are part of Leo's system of equations

Step-by-step explanation:

The formula for the amount in an account compounded annually is ...

  A = P(1 +r)^t

For the given amounts and variables, that is ...

  y = 500(1.025)^x . . . . matches F

__

The formula for the amount in an account compounded continuously is ...

  A = P·e^(rt)

With given values, this is ...

  y = 400e^(0.02x) . . . . matches A
