3x + y = -4 -6x – 4y = 14

Mathematics
1 answer:
zubka84 [21]3 years ago
5 0

Answer: y = -3x-4

y = -6/4x-14/4

Step-by-step explanation:

3x+y=-4... you move the 3x to the other side it become negative and your answer will be y = -3x-4

-6x-4y=14... you move the -6x to the right side which will be 6x+14 then you divide -4 from left to right to leave the y itself and your answer will be y = -6/4x-14/4

By using the given graph:

  • When x = -2, the value of the function is f(-2) = 1
  • When x = -0.5, the value of the function is f(-0.5) = 0.75
  • When x = 0, the value of the function is f(0) = 1.25
  • When x = 2.5, the value of the function is f(2.5) = 3
  • When x = 6, the value of the function is f(6) = 0
<h3></h3><h3>How to use the graph to find the values of the function?</h3>

Suppose that we want to find the value of the graphed function when x = a.

  • Then we first need to identify x = a in the horizontal axis.
  • Then we move upwards (or downwards) until we meet the curve of the function.
  • Now you can move horizontally towards the vertical axis, where you can read the y-value associated to the x-value.

Now we can do these steps for each of the wanted values.

  • When x = -2, the value of the function is f(-2) = 1
  • When x = -0.5, the value of the function is f(-0.5) = 0.75
  • When x = 0, the value of the function is f(0) = 1.25
  • When x = 2.5, the value of the function is f(2.5) = 3
  • When x = 6, the value of the function is f(6) = 0

2. Find the theoretical probability of not rolling a 4.
mezya [45]

Answer:If a die is rolled once, determine the probability of rolling a 4: Rolling a 4 is an event with 1 favorable outcome (a roll of 4) and the total number of possible outcomes is 6 (a roll of 1, 2, 3, 4, 5, or 6). Thus, the probability of rolling a 4 is 1/6.

If a die is rolled once, determine the probability of rolling at least a 4: Rolling at least 4 is an event with 3 favorable outcomes (a roll of 4, 5, or 6) and the total number of possible outcomes is again 6. Thus, the probability of rolling at least a 4 is 3/6 = 1/2

Step-by-step explanation:For example, when a die is rolled, the possible outcomes are 1, 2, 3, 4, 5, and 6. In mathematical language, an event is a set of outcomes, which describe what outcomes correspond to the "event" happening. For instance, "rolling an even number" is an event that corresponds to the set of outcomes {2, 4, 6}. The probability of an event, like rolling an even number, is the number of outcomes that constitute the event divided by the total number of possible outcomes. We call the outcomes in an event its "favorable outcomes".

the managers of a corporation were surveyed to determine the background that leads to a successful manager. each manager was rat
lubasha [3.4K]

The probability that the selected manager has no college background and only have a fair look is 0.05625

Table is missing. Attached below.

Given,

We have to find the probability that the selected manager has no college background and only have a fair look;

From the table;

The total number of managers surveyed = 160

Number of managers surveyed are fair = 9

Probability;-

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

Here,

The probability = Number of managers surveyed are fair / The total number of managers surveyed

The probability = 9/160 = 0.05625

That is,

The probability that the selected manager has no college background and only have a fair look is 0.05625
