Answer:
6in²
Step-by-step explanation:
Given that :
Base of right angle triangle = 3
Height of right angle triangle = 4
Area of a triangle = 1/2 * base * height
Area of triangle = 1/2 * 4 * 3
Area of triangle = 2 * 3
Area of triangle = 6in²
Probabilities are used to determine the chances of events
The probability that two are nearsighted and one is not, is 0.0645
<h3>How to determine the probability</h3>
The given parameters are:
n = 3 -- the number of Australians selected
r = 2 --- the number that are nearsighted
p = 16% --- the proportion that are nearsighted.
The probability that two are nearsighted and one is not, is calculated using the following binomial probability formula
So, we have:
Hence, the probability that two are nearsighted and one is not, is 0.0645

Hi!
To answer this, first we have to find how much 1 notebook costs. We can do this by dividing:
Cost/amount = ?
Or in this case
5.25/5 = 1.5
Now we have to find how much 3 notebooks cost. We can do this by multiplying:
Cost of one x amount = ?
Or in this case
1.5 x 3 = 3.15
The answer is 3.15
Hope this helps! :)
Answer:
10.2 inches
Step-by-step explanation:
we know that
In this problem we have two cases
First case
The given lengths are two legs of the right triangle
so
Applying the Pythagoras Theorem
Find the length of the hypotenuse
substitute
Second case
The given lengths are one leg and the hypotenuse
so
Applying the Pythagoras Theorem
Find the length of the other leg
substitute
Find the difference between the two possible lengths of the third side of the triangle
so
