Correct answer is: P(x<6) is 0.123 and it is usual.
Solution:-
Given that the time a person takes to decide which shoes to purchase follows normal distribution. Which has mean = 8.21 minutes and standard deviation 1.90
Then probability of individual takes less than 6 minutes is
P(X<6) = 
= 
= 0.1230
Typically we say an event with a probability less than 5% is unusual.
But here P(X<6) = 0.123 is greater than 5% hence this is usual.
Answer:
Ar = ¼√3 As
Step-by-step explanation:
Area of an equilateral triangle is:
Ar = ¼√3 s²
Area of a square is:
As = s²
Substituting:
Ar = ¼√3 As
Answer:
B or 2
Step-by-step explanation:
because i got u the proofs
Answer :
to find area of the square = 6 to the power 2
to find the area of the rectangle = (5x + 12) * 5x
therefore,
square's area = 36
rectangle's area = 5x*5x + 12 * 5x
= 25x * 60x
Now we have to find the sum of both the areas,
so, 36 + 1500 = 1536
