Students in a political science course were asked to describe their politics as "Liberal", "Moderate", or "Conservative." Here are the results: Politics Liberal Moderate Conservative Total Female 40 34 14 88 Male 48 50 26 124 Total 88 84 40 212 Given that the student is male what is the probability that he considers himself to be a "Liberal"? Round your answer to three decimal places if necessary. a. 0.226 c. 0.387 b. 0.415 d. 0.455 Please select the best answer from the choices provided A B C D
Answer:
a
Step-by-step explanation:
The probability that he considers himself to be a "Liberal is 0.387.
Option C is the correct answer.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The probability that a male student considers himself to be a "Liberal" can be found by dividing the number of "Liberal" males (48) by the total number of males (124):
P(Liberal | Male) = 48/124
P(Liberal | Male) = 0.387 (rounded to three decimal places)
Therefore,
The probability that he considers himself to be a "Liberal is 0.387.

Answer:
a¹⁸b²⁴c⁵⁴
Step-by-step explanation:
(aᵇ)ᶜ = aᵇᶜ = aᵇ×ᶜ
(-aⁿ)ᵒᵈᵈ = -aⁿ
(-aⁿ)ᵉᵛᵉⁿ = aⁿ
aⁿ × aⁿ = aⁿ⁺ⁿ
_________
In this situation, 6 is an even exponent which means that the negative coefficient of this 9th degree monomial will be positive. Now the only step is to multiply the exponents by the exponent outside of the perenthesis which is 6.
so (-a³b⁴c⁹)⁶ = ((-a³)⁶(b⁴)⁶(c⁹)⁶) = ((a³ˣ⁶)(b⁴ˣ⁶)(c⁹ˣ⁶)) = ((a¹⁸)(b²⁴)(c⁵⁴)) = a¹⁸b²⁴c⁵⁴

how does simple
interest show proportional reasoning and
relate to the percent equation?
Answer:
Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.
Step-by-step explanation:
Simple interest show proportional reasoning and relate to the percentage equation.
Relationship between percentage and proportion:The relationship between proportion and percentage occurs when a particular proportion gets multiplied by 100 it gives the percentage of parts takenmeans,
[tex]\dfrac{\text{Parts}}{Whole}\times 100= \text{Percentage}[/tex]
Similarly,
when a percent gets multiplied by total it gives the number of parts taken means,
[tex]\text{Parts} = \text{percent} \times\text{whole}[/tex]
We can also use cross product to find out if the two ratios form a proportion.Here we can see that 3/15 and 6/44 are proportions, since their cross products are equal.
Percent means hundredths or per hundred and is written with the signal, %. Percent is a ratio where we compare numbers to 100 which means that 1% is 1/100.
Therefore, simple interest show proportional reasoning and relates to the percentage equation.
