Describe how to transform the graph of g(x) = logx into the graph of f(x) = 2 log(4

Suppose spin a spinner with eight equal sectors, numbered 1 to 8. What is the probability of spinning a 3 or an 8?

olasank [31]

Given, in the spinner 8 equal sectors, numbered 1 to 8.

So total numbers = 8.

Let, the probability of spinning a 3 is P(Three) and spinning an 8 is P(Eight).

Now we know that, probability of an event E is

P(E) = (number of outcomes in the event)/ (total number of possible outcomes).

So here number of outcomes for spinning a 3 is 1 and we have got total outcomes = 8.

So P(Three) = $\frac{1}{8}$

Similarly, P(Eight) = $\frac{1}{8}$

Probability of spinning a 3 or an 8 = P(Three) + P(Eight)

= $\frac{1}{8} + \frac{1}{8}$

As the denominator is same we can add the numerator.

= $\frac{(1+1)}{8}$

= $\frac{2}{8}$

Now we have to simplify the fraction by dividing the numerator and denominator by a common factor of them.

The common factor of 2 and 8 is 2. So by dividing them we will get,

= $\frac{1}{4}$

We have got the required answer.

The probability of spinning a 3 or an 8 is $\frac{1}{4}$

Which equation can be used to represent the statement? Sixteen is the same as one and two-tenths times a number added to negativ

andreyandreev [35.5K]

The equation can be used to represent statement 'Sixteen is the same as one and two-tenths times a number added to negative 8' is,

$16=1.2n+(-8)$

<h3>How to write algebraic equation from statement? </h3>

Algebraic equation are the expression which consist the variables, coefficients of variables and constants.

The algebraic equation are used represent the general problem in the mathematical way to solve them.

Steps to write down the simple algebraic equation from statement-

Identify all the factors of the expression.

Assume a variable for the changing values.

Put a coefficient for the variable, if there is any rate of change of variable.

Use constant numbers for the fixed values.

Given information-

The given statement is 'sixteen is the same as one and two-tenths times a number added to negative 8'.

The statement given in the problem is talking about a unknown number. Let the unknown number is $n$ .

The number is sixteen is the same as one and two-tenths times a number added to negative 8.

This means when our number n, multiplied by the fraction 2/10, and added by the negative 8, then it becomes equal to the number 16. Mathematically,

$16=n+\dfrac{2}{10}\times n+(-8)\\16=1.2n+(-8)$
