<u>T</u>he converse, inverse and contrapositive of each conditional statement include:

  1. <u>Converse:</u> If two angles have a common side, then they are adjacent.
  2. <u>Inverse:</u> If two angles are not adjacent, then they do not have a common side.
  3. <u>Contrapositive:</u> If two angles do not have a common side, then they are not adjacent.

<h3>What is a conditional statement?</h3>

A conditional statement can be defined as a type of statement that can be written to have both a hypothesis and conclusion. Thus, it typically has the form "if P then Q."

<u>Where:</u>

P and Q represent sentences.

In this scenario, we would write the converse, inverse and contrapositive of each conditional statement as follows:

  • <u>Converse:</u> If two angles have a common side, then they are adjacent.
  • <u>Inverse:</u> If two angles are not adjacent, then they do not have a common side.
  • <u>Contrapositive:</u> If two angles do not have a common side, then they are not adjacent.

Assume that the probability of having sickle cell anemia is 0.15 and the probability of being African-American is 0.45 in a give
irina1246 [14]

Answer:

the probability of having sickle cell anemia given that you are African-American is  P( B|A) =0.288

Step-by-step explanation:

Using Bayes's theorem

P( B|A) = P( A∩B)/P(A)

where P( B|A) = probability of the event B knowing that A happened , P( A∩B) = probability that A and B happen (joint probability of A and B) , P(A) = probability of event A

if B= probability of having sickle cell anemia and A= probability of being African-American

then

P( A∩B) = 0.13

P(A) = 0.45

then

P( B|A) = P( A∩B)/P(A)  = 0.13/0.45 = 0.288

P( B|A) =0.288

Diana bought a car for $5000 and plans to sell it to make a 20% profit. What should she sell it for to make the profit she desir
nalin [4]
You need to know 20% of $5000.  "Of" means "times".  

$5000 x 0.20 (which is 20% written as a decimal)

=$1000 profit she wants to make

$5000 (original price) + $1000 (profit) = $6000 (sale price)

Nikitich [7]

Options :

(A.) y=558-273x (B.) y=264+142x (C.) y = 55.8 +2.79x (D.) y= -26.4-1.42x

Answer:

C.) ŷ = 2.79X + 55.8

Step-by-step explanation:

Given the data:

cost (x): 9 2 3 4 2 5 9 10

Number of products sold: 85 52 55 68 57 86 83 73

Using the online regression calculator to generate a linear regression plot of the given data: the model obtained is given below

ŷ = 2.79X + 55.8

With y being the predicted or dependent variable

Slope or gradient of the line = 2.79

X = the independent variable

55.8 = the intercept.
