Evaluate \dfrac{3}{2}+(-k)+(-2)

Mathematics
1 answer:
Dimas [21]2 years ago
4 0

As I understand, we need to evaluate the given rational expression, we will get that the evaluated expression is equal to - 1/10

<h3>Evaluating expressions:</h3>

Evaluating an expression just means that we need to replace the variable in the expression for a given value, here we have the expression:

\frac{3}{2} + (-k) + (-2)

And we want to evaluate it in:

k = -\frac{2}{5}

So we just need to replace k by that value in the above expression, we will get:

\frac{3}{2} + (-(-\frac{2}{5} )) + (-2)

Now we can just solve this:

\frac{3}{2} + (-(-\frac{2}{5} )) + (-2)\\\\\frac{3}{2} + \frac{2}{5}  + (-2)\\\\\frac{15}{10} + \frac{4}{10}  + (-2) = \frac{19}{10} - \frac{20}{10}= -\frac{1}{10}

what does it mean to be a function how can you determine functionality of a relation or eqaution graph
mylen [45]
Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.

Pat is required to sell candy bars to raise money for the 6th grade field trip. There is a 40% chance of him selling a candy bar
labwork [276]

Answer:

It will take him about 13 houses to sell the 5 candy bars.

Pat has an 18% chance of selling his last candy in the 11th house.

Step-by-step explanation:

Since Pat is required to sell candy bars to raise money for the 6th grade field trip, and there is a 40% chance of him selling a candy bar at each house, and he has to sell 5 candy bars in all, to determine the number of houses it takes and determine the probability he sells his last candy bar at the 11th house, the following calculations must be performed:

5 / 0.40 = X

12.5 = X

So, it will take him about 13 houses to sell the 5 candy bars.

5/11 = X

0.45 = X

0.45 x 0.4 = 0.18

Thus, Pat has an 18% chance of selling his last candy in the 11th house.
