Polar coordinates : r= - 5, α= - 180⁰.
Rectangular coordinates : 
x=r*cosα = (-5)*cos (-180⁰)=(-5)*(-1)=5
y=r*sinα = (-5)*sin(-180⁰)=(-5)*0=0

So, <span>(-5, -180°) (polar coordinates) is the same as (5,0) (rectangular coordinates).</span>

Given that an adult likes soccer, what is the probability the adult is aged 18–30? 8.1% 18.1% 24.5% 44.4%
dsp73

The probability that an adult likes soccer is aged between  18–30 will be 44.4%.

We have an adult who likes soccer.

We have to determine the probability the adult is aged 18–30.

<h3>What is Probability?</h3>

The formula to calculate the probability of occurrence of an event 'A' can be written as -  

P(A)  =  \frac{n(A)}{n(S)}

where -

n(A) = Number of outcomes favorable to event A.

n(S) = Total number of outcomes.

According to question, we have an adult likes soccer.

The answer to this question is based on the hypothesis that the adults between 18 - 30 are highly energetic. To be more precisely - the adults in the range 18 - 24 and 24 - 30 are highly energetic and full of stamina. Above the age 30, the number of adults who like soccer will start to decrease and will hit nearly zero between the age range of 55 - 65 as the adults in this age group found it very difficult to even walk.

Mathematically -

The probability of an event A = an adult likes soccer is aged between  18–30 will be the highest value among the ones mentioned in options.

Hence, the probability that an adult likes soccer is aged between  18–30 will be 44.4%.

Use the Pythagorean theorem to find the third side of the triangle.​
ziro4ka [17]

Answer:

9.2 (1DP)

Step-by-step explanation:

  1. First you do 10^2 which is 10 X 10 = 100
  2. Then you do 4^2 which is 4 X 4 = 16
  3. Then you do 100 - 16. The way Ive learnt it is that if the hypotenuse isn't the one you have to find then minus of it it is then plus. So 100 - 16 = 84
  4. A^2 + B^2 = C^2 84 is C^2 meaning now you have to square root it
  5. Square root of 84 is 9.2 to 1 DP
