Mathematics
1 answer:
WINSTONCH [101]3 years ago
4 0

Answer:

x > 0.5

Step-by-step explanation:

Given

- 0.2x + 1.2 < 1.1 ( subtract 1.2 from both sides )

- 0.2x < - 0.1

Divide both sides by - 0.2, reversing the symbol as a result of dividing by a negative quantity.

x > 0.5

Jackson is playing a game of chance where he must randomly draw a marble out of a jar. He calculates the probability of drawing
Sindrei [870]

Using complementary events, considering a \frac{1}{4} probability of drawing a red marble, the probability of not drawing a red marble is of \frac{3}{4}.

<h3>What are complementary events?</h3>

They are mutually exclusive events which have the sum of their probabilities as 1.

In this problem, we consider that there is a \frac{1}{4} probability of drawing a red marble, and since drawing a red marble and drawing a non-red marble are complementary events, we have that:

\frac{1}{4} + p = 1

p = \frac{3}{4}

The probability of not drawing a red marble is of \frac{3}{4}.

In using the multiple regression method, we can model the effects of the different levels of a qualitative independent variable
attashe74 [19]

For the levels of qualitative, the variable called dummy variables is used in the multiple regression method.

According to the statement

we have given that the by which method we use the different levels of a qualitative independent variable and we have to explain about it.

So, For his purpose, we know that the

A dummy variable is a variable that takes values of 0 and 1, where the values indicate the presence or absence of something.

And in the multiple regression method there are a lot of different variables which are used for a qualitative and for this a variable is used which is called the dummy variables.

By this variables we show the analysis between the given data. it gives the output in the 0 and 1 numbers.

So, For the levels of qualitative, the variable called dummy variables is used in the multiple regression method.
