By taking the quotients between the areas, we see that:
<h3>
How to find the probabilities?</h3>
First we need to find the areas of the 3 shapes.
For the triangle, the area is:
T = 3*5/2 = 7.5
For the blue square, the area is:
S = 3*3 = 9
For the rectangle, the area is:
R = 10*6 = 60
Now, what is the probability that a random point lies on the triangle or in the square?
It is equal to the quotient between the areas of the two shapes and the total area of the rectangle, this is:
P= (7.5 + 9)/60 = 0.275
b) The area of the rectangle that is not the square is:
A = 60 - 9 = 51
Then the probability of not landing on the square is:
P' = 51/60 = 0.85

Answer: (B) Systematic
Step-by-step explanation:
(A) Random : In this researcher randomly selects individual from population to make sample.
(B) Systematic : It is a kind of random sampling method where researcher decide the starting point to select individual , then follow a systematic pattern to select them.
(C) Stratified : It is a kind of random sampling method where researcher divides the population into groups ( on the basis of characteristics) called as strata , then selects individuals from each strata.
(D) Cluster : It is a kind of random sampling method where researcher divides the population into groups known as clusters , then randomly selects clusters to include in sample.
(E) Simple random : It is a kind of random sampling method where researcher randomly selects individual from population to make sample.
Since , a random number is generated to determine a starting position in the list and then every tenth attendee is placed in the sample.
That means sponsors follow as systematic pattern.
Therefore , the methods was used to select the probability sample : (B) Systematic
Ok, so...what is the question?...
Answer:
50 seconds, 25 seconds longer
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
1) 5/0.1=5x10=50 seconds
2) It would take the cooter turtle 5/0.5=25 seconds
50 seconds-25 seconds=It would take the giant tortoise 25 seconds longer
