Since the whole set is composed of a total of 55 people, with 45 people being drinks of either coffer or tea, then the remaining people not included in the 45 would be the non-drinkers. So 55-45, meaning there are 10 people who drink neither tea nor coffee. To obtain the probability:

10/55 = 2/11 = 0.182

Therefore, the probability of a person being picked at random does not drink either coffee or tea is 0.182.

Answer:

no, the numbers are not pythagoras triple

Step-by-step explanation:

find the complete question in the attached image

If the angle is a right angle would be determined using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

20² + 10² =

400 + 100 = 500

500 is not equal to the square of 25

so it is not a right angled triangle

If 12x=12−−√11, what value of x makes this equation true?
Solnce55 [7]

Answer:

\dfrac{1}{11}

Step-by-step explanation:

Apply exponent rule:  

\sqrt[n]{a} =a^{\frac{1}{n}}

\implies \sqrt[11]{12}=12^{\frac{1}{11}}

\implies 12^x=12^{\frac{1}{11}}

\implies x = \dfrac{1}{11}

Answer:

12 \sqrt{2}

Step-by-step explanation:

you can use hypotenuse formula

45-45-90 isosceles right triangle

so, 45= x

x² + x² = 24²

2x² = 24²

x²= 24.12

x= \sqrt{288}  = 12 \sqrt{2}

or :

you can use this rule: if you see a 45 45 90 isosceles right triagngle (you can look picture) 45=a cm and 90 = a\sqrt{2}

cm

so ;

a \sqrt{2}  = 24

a= 12 \sqrt{2}

hope this helps ^-^
