Answer:
6 : 11
Step-by-step explanation:
the ratio 6 : 11 applies to all linear measure in the similar polygons
Both side lengths and perimeter are linear, hence
ratio of both is 6 : 11
Answer:
see explanation
Step-by-step explanation:
Given
6a² - a - 5 = 0
Consider the factors of the product of the a² term and the constant term which sum to give the coefficient of the a- term.
product = 6 × - 5 = - 30 and sum = - 1
The factors are - 6 and + 5
Use these factors to split the a- term
6a² - 6a + 5a - 5 = 0 ( factor the first/second and third/fourth terms )
6a(a - 1) + 5(a - 1) = 0 ← factor out (a - 1) from each term
(a - 1)(6a + 5) = 0
Equate each factor to zero and solve for a
a - 1 = 0 ⇒ a = 1
6a + 5 = 0 ⇒ 6a = - 5 ⇒ a = -
Solution set = { 1, - }
Answer: The percent of red lights last between 2.5 and 3.5 minutes = 95.44% approx.
Step-by-step explanation:
Given: Mean time = 3 minutes
standard deviation = 0.25 minutes
The probability of red lights last between 2.5 and 3.5 minutes :-
The percent of red lights last between 2.5 and 3.5 minutes = 95.44% approx.
Answer:
0.02826855123 or 35.37
Step-by-step explanation:
24/849 = 0.02826855123
849/24 = 35.37
