Sample space is 36C4
Now, we want to know all of the combinations that have 1 digit in it.
So, we can have one here:
1XXX
X1XX
XX1X
XXX1
But we have 10 different digits to choose from. So, we need to introduce the combination term, nCr, where n is a list of all digits and r is how many we want.
Since we only want one, we will need 10C1 for the number of digits. But we need to choose three lowercases, so it becomes 10C1 × 26C3
Since it's a probability question, we need to divide that by our sample space, 36C4, and our percentage becomes 44%
Answer:
1.575
Step-by-step explanation:
I just made it to a proper fraction then put them over 100
Answer: V = 100.48
Step-by-step explanation:
To get this value, you need to know the formula of the volume of the cone, which is:
V = π*r^2*h / 3
Where:
r: cone radius
h: height
π: value of pi which is 3.14
Now the radius, is half the diameter of base of the cone so:
r = 8 / 2 = 4 units
Now we have all the data needed to get the volume of the cone, let's use the expression given above:
V = 3.14 * (4)^2 * 6 / 3
V = 3.14 * 16 * 6 / 3
V = 301.44 / 3
V = 100.48
Answer: 72.4 ft
Step-by-step explanation: A2+B2=C2 20squared plus Bsquared=30 22.4 squared plus 20squared equals 30squared and when you add all that together you get 72.4 ft
