Answer:
1/12 is the probability of getting sum of 4 everytime
Step-by-step explanation:
The Probability of getting the sum of 4 when a dice is rolled is 1/12. In a sample space of 36, only 3 occurrence lead to sum of 4 (1,3) (2,2) and (3,1).
For each time the dice is rolled, the Probability of sum 4 is 1/12.
Answer: 2x^2
The three terms are
2x^2
-3x
5
as they are separated by a plus sign. You can think of it as 2x^2 + (-3x) + 5 if you want. The quadratic term is the term with the exponent of 2
<span>let the width of the strip x in meters
we need to find the value of x
Dimensions of the new lawn are given as
</span>(7+x) by (5+x)
Area of the lawn is given as
6.25m^2
<span>
(7+x)(5+x) = 6.25
</span><span>35 + 12x + x^2 = 6.25
x^2 + 12x+28.75 = 0
In the above equation the values are given as
a = 1, b=12, c=28.75
</span>put these values in quadratic equation and you will get the answer.<span />
