Consecutive trials until S happens
Number of trials
For every possible outcome, the last 3 must be SSS. So, we have:
The only possibility here is: 
because 3 trials implies that all outcomes must be S.
The only possibility here is:
because 4 trials implies that the first outcome must be F
The possibilities are:
because 5 trials implies that the first and the second outcomes must be FS or SF.
The possibilities are:
because 6 trials implies that the first three outcomes are: FFF, SSF and SFF
The possibilities are:
because 7 trials implies that the first three outcomes are: FFFF, FSSF and SSFF and FFSF (similar to (e))
Answer: 205,209
Step-by-step explanation:
We want to find a perfect cube that is closest to the number N = 205,632
A perfect cube number is a number such that the square root is a whole number.
Now, to search this number we must take the square root of N:
n = √(205,632) = 453.47
Now, we can round it down or up and get whole numbers, and the squares of those whole numbers will be perfect squares that are near 205,632, lets start with rounding down.
n = 453
the square of 453 is:
453^2 = 205,209
If instead we round up the 453,47, we would get:
n = 454
and the square will be
n = 454^2 = 206,116
Now, to see which one is closser to N, we can take the differences:
205,632 - 205,209 = 423
206,116 - 205,632 = 484
so if we take n = 453 we are closser no N, then the perfect square that is closest to 205,632 is 205,209
Answer:
0 length, the bird is touching the top of the fish
Step-by-step explanation:
x = 9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
51 = 4x + 15
Step 2: Flip the equation.
4x + 15 = 51
Step 3: Subtract 15 from both sides.
4x + 15 − 15 = 51 − 15
4x = 36
Step 4: Divide both sides by 4.
4x/4 = 36/4
X = 9
