Answer:
173.2
Step-by-step explanation:
area of equilateral triangle = √3 / 4 l^2
so area =173.2
Answer:
A rectangle has four right angles, A triangle has 3 sides, A square has 4 equal sides
Step-by-step explanation:
15 min is 1/4 of an hour so it can run 44x 1/4 or 44/4 =11miles in 15 min
Answer:
whatttt!!!!!!!!!!
Step-by-step explanation:
Answer:
(A) There should have been 5 outcomes of HT
(B) The experimental probability is greater than the theoretical probability of HT.
Step-by-step explanation:
Given
-- Sample Space
--- Sample Size
Solving (a); theoretical outcome of HT in 20 tosses
First, calculate the theoretical probability of HT


Multiply this by the number of tosses


<em></em>
Solving (b); experimental probability of HT
Here, we make use of the table


---- Experimental Probability
In (a), the theoretical probability is:

---- Experimental Probability
By comparison;
