To solve this problem you must apply the proccedure shown below:
1. You have that the formula for calculate the area of a triangle is:
A=bh/2
Where A is the area of the triangle, b is the base of the triangle and h is the height of the triangle.
bh/2=124
bh=124x2
bh=248
2. The problem asks for the new area of the triangle <span>if its base was half as long and its height was three times as long. Then, you have:
Base=b/2
Height=3h
3. Therefore, when you substitute this into the formula for calculate the area of a triangle, you obtain:
A'=bh/2
(A' is the new area)
A'=(b/2)(3)/2
A'=3bh/4
4. When you substitute bh=248 into </span>A'=3bh/4, you obtain:
<span>
A'=186 units</span>²
<span>
The answer is: </span>186 units²

Probability: Probability of an event to occur is given by:
Probability of Wednesday:
Probability of first day rainy:
Probability that first day is rainy Wednesday:
Let probability
Since these two events are independent
Percentage chances of rainy Wednesday
Answer: 3x - 146
Step-by-step explanation:
Add all "x" and numbers
3x - 122 - 32 + 1 + 7
3x - 154 + 8
3x - 146
Probabilities! In order to find the answer you first have find out the total amount of marbles that you have. So:
[7 + 9 + 6] = 22
This number will go into the denominator.
The next step is to find how how many marbles are not green. To do that you simply add the red marbles and the blue marbles. So:
[7 + 9] = 16
This number will go in the numerator.
The probability of you choosing a marble that is not green is 16/22. You can also simply this and it would be 8/11.
