Use the table to answer a) through c) below. Opinions on Global Warming Nonissue Serious Concern Total 500 500 200 1200 Democratic 80 Political Party Republican 300 Independent110 490 42 200 90 Total 710 a) What is the probability that a randomly selected registered voter who is a Republican believes that global warming is a serious issue? 0.400 (Round to three decimal places as needed.) b) What is the probability that a randomly selected registered voter is a Republican given that he or she believes global warming is a serious issue? 0.167(Round to three decimal places as needed.)
Answers
Republican given that he or she believes global warming is a serious issue is lower than the probability of a randomly selected registered voter
What is Probability?
Probability is the branch of mathematics that deals with the quantification of uncertainty. It is the likelihood of an event happening, expressed as a number between 0 and 1. Probability is used to infer the likelihood of outcomes based on past data and current conditions. Probability is important in decision-making, risk management, and finance.
The probability of a randomly selected registered voter being a Republican given that he or she believes global warming is a serious issue is lower than the probability of a randomly selected registered voter who is a Republican believing that global warming is a serious issue, because there are more total registered voters who believe that global warming is a serious issue than there are registered Republicans who believe that global warming is a serious issue. This means that the probability of a randomly selected registered voter being a Republican given that he or she believes global warming is a serious issue is lower than the probability of a randomly selected registered voter who is a Republican believing that global warming is a serious issue, because there are more total registered voters who believe that global warming is a serious issue than there are registered Republicans who believe that global warming is a serious issue.

No, political party affiliation and opinion on global warming are not independent because the probability of a randomly selected registered voter being a Republican is not the same for both "nonissue" and "serious concern" opinion on global warming.

No, they are not independent. This is because the probability of a Republican being selected given that they believe global warming is a serious issue is not equal to the probability of a Republican being selected regardless of opinion on global warming (0.400 vs 0.167). This implies that there is a higher probability of a Republican being selected if they believe global warming is a serious issue.

The height of the triangle is 11 cm
What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the height of the triangle be = h
The area of the triangle A = 49.5 cm²
The base of the triangle b = 9 cm
So , the area of the triangle is given by the equation ,
Area of the triangle = ( 1/2 ) x Length x Base
Substituting the values in the equation , we get
A = ( 1/2 ) x b x h
49.5 = ( 1/2 ) x 9 x h
Multiply by 2 on both sides of the equation , we get
9h = 99
Divide by 9 on both sides of the equation , we get
h = 99/9
h = 11 cm
Therefore , the value of h is 11 cm
Hence , the height of the triangle is 11 cm

A $220 item marked up by 60% would have a final selling price of $352.
what is $220 marked up 60%
A 60% markup on $220 would be calculated as follows:
Markup = Original Price × Markup Percentage
Markup = $220 × 0.60
Markup = $132
To find the final selling price, you add the markup to the original price:
Final Price = Original Price + Markup
Final Price = $220 + $132
Final Price = $352
Therefore, a $220 item marked up by 60% would have a final selling price of $352.

6x - 5y = 0 ——(1)
x - 5y = -25 ——(2)
(1) - (2):
6x - 5y - (x - 5y) = 0 - (-25)
6x - 5y - x + 5y = 0 + 25
5x = 25
x = 5
Sub x = 5 into (2):
5 - 5y = -25
-5y = -30
y = 6
