First, start of by saying what the probability of getting a 4 is, which is 1/6.
Now, this means the probability of not getting a 4 is 1-(1/6)=(5/6), since the total probability is 1.
After doing this, you should think about what it means to only get 4 on the last trial, the 4th trial. It means that the probabilities of the 1st, 2nd, and 3rd trial were (5/6) each. The 4th trial had a probability of (1/6). So the probability would be calculated as following: (

=

. You can use a calculator or your computer to find out that the probability is 125/1296.

Answer:
1.8
Step-by-step explanation:
cuz
if 1L is equal to 0.26
then 7×0.26
= 1.8
hope it helps
Since we are rounding to the nearest hundreds place in 222,977 the hundreds would be the 9. The seven behind it would make the number round up since the rule is 0-5 round down 6-9 round up. you round the 9 up to 10 so you add 1 to the next number since you cant have 222,1000. thats wrong . the answer is
223,000
Answer:
<h3><u>Part (a)</u></h3>
From inspection of the diagram, the pattern is:
Step 1: 1² + 1
Step 2: 2² + 2
Step 3: 3² + 3
Let x = step number
Let y = total number of squares
Therefore, the equation that represents the relationship is:
y = x² + x
<h3><u>Part (b)</u></h3>
<u />
x² relates to the large square made up of small squares (top part of the image of each step)
x relates to the rectangle of small squares (bottom part of the image of each step)
y is the total number of small squares in the image of each step.
