Step-by-step explanation:
Hello,
Area under the curve is 1.
So p(x>5)=1-p(x<5)=1-0.0625=0.9375
Answer A
Answer:
Step-by-step explanation:
<u>Sum of the angles of triangle equals 180</u>
- x + 12 + 2x - 29 + x + 5 = 180
<u>Simplified</u>
Let us assume the number to be = x
Then
(80/100) * x = 56
4x/5 = 56
4x = 56 * 5
4x = 280
x = 280/4
= 70
The value of the unknown number is 70. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems in future without requiring any help from outside. Only thing that needs to be taken care of is the calculation part.
