Remark
You have to guess what the question is. I'm assuming that it is either the black triangle to the blue one or the blue one to the black one. Be careful when you post a question to see if you have included a question.
Answer
<em>Ratio of blue to black</em>
The distance of the left most point of the blue triangle to the y axis is 3. The same point on the black one is 1
blue/black = 3/1
<em>Ratio of black to blue</em>
ratio of the black triangle to the blue one is 1/3
The answer will depend on the question. Notice that the two answers are reciprocals.
I think because the number of blocks is different, but the proportion of space can be filled in the same.
The probability of getting all 5 right would be 1/<span>3125
This is because each question has one choice. Making it a 1/5 chance for each question.
Now if you combine if you add the rest you will have to calculate.
You would do the calculation by multiple the chance for a correct answer for each question together.
1/5 x 1/5 x 1/5 x 1/5 x 1/5 = 1/3125

Answer:
![p=\left \{ {{15.99,m[tex]\leq](https://tex.z-dn.net/?f=p%3D%5Cleft%20%5C%7B%20%7B%7B15.99%2Cm%5Btex%5D%5Cleq)
130} \atop {15.99+0.09*(m-130),m>130}} \right.[/tex]
Step-by-step explanation:
We will have a partial funcion to define an expression for the monthly phone charge, because we have a condition that changes the monthly cost.
For months under 130 minutes, there will not be any additional charge other that tha base monthly cost, so the expression for the months under 130 minutes will be the monthly fee.
For months over 130 we will have the same information than above, but we have to add a fee for every minute over 130 minutes. To find the amaunt of minutes over 30 minutes we will just subtract 130 to the amount of minutes used: (m-130). Then we will multiply that number times the cos of each minute over 130 minutes: 9*(m-130). Finally we will add the basic phone fee: 15.99 + (0.09*(m-130)).
Now we set the conditions and use the correct notation for a partial function and we get:
130} \atop {15.99+0.09*(m-130),m>130}} \right.[/tex]
You would divide 6.51 by 3
$6.51/3 = 2.17
