Therefore, $\frac{8}{7}= 1.14$ cannot represent the probability of an event. So, option C is correct.

We need to identify which of the given option cannot represent the probability of an event.

<h3>What is probability?</h3>

The probability of an event occurring is defined by probability. There are many instances in real life where we may need to make predictions about how something will turn out. The outcome of an event may be known to us or unknown to us. When this happens, we say that there is a chance that the event will happen or not.

By simply dividing the favourable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favourable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.

Now, $\frac{1}{14} =0.0714, \frac{8}{7}= 1.14$ and $\frac{20}{21}=0.952$ .

Therefore, $\frac{8}{7}= 1.14$ cannot represent the probability of an event. So, option C is correct.

Why are these terms considered Like Terms? 3y, y, 4y. Why are these terms not considered Like Terms? 3y, 3x, 3xy

Art [367]

Answer:

like terms require the variables to be the same. 3y,y 4y are like terms because they all have y in common. 3y,3x,3xy are not like terms because the variable is not the same.

The sum of 3 numbers is 145. Seven times the second number is twice the first number and twice the second number is six times th

igor_vitrenko [27]

Answer:

$\frac{7}6}$

Step-by-step explanation:

Let the 3 numbers be $x,y,$ and $z$

As per question,

$x+y+z=145$

Also, 7 times the second number is twice the first, so

$7y=2x\\\frac{x}{y}=\frac{7}{2}----------- 1$

Again, twice the second number is 6 times the third number, so

$2y=6z\\\frac{2}{6}=\frac{z}{y}\\\frac{z}{y}=\frac{1}{3}---------- 2$

Now, multiply equations 1 and 2. This gives,

$\frac{x}{y}\times \frac{z}{y}=\frac{7}{2}\times \frac{1}{3}\\\frac{x\times z}{y\times y}=\frac{7\times 1}{2\times 3}\\\frac{xz}{y^2}=\frac{7}{6}$

Therefore, the ratio of the product of the first and the third numbers to the square of the second number is $\frac{7}6}$

Triangles ABC and DEF are similar triangles. What are the lengths of the unknown sides?

Aleksandr-060686 [28]

Answer:

DF = 52

AB = 48

Step-by-step explanation:

Use the two lengths of sides already given.

Divide to find the scale factor:

20 / 5 = 4

Scale factor: 4

Now multiply to find the unknown sides:

13 × 4 = 52

12 × 4 = 48

DF = 52

AB = 48

Hope this helped.

When line sets have been altered, they may not be treated as self-contained systems of their own?

dmitriy555 [2]

First of all, you may alter line sets. When you do, the nitrogen charge is released into the atmosphere.
You can then pressure the lines with a tracing gas in order to check if there are leaks in the connections you've made.
After the test is complete, you have to evacuate the line set before opening the valves to start the system.

Knowing this, we can say that line sets, when altered, may NOT be treated as self-contained systems of their own is a FALSE statement.
