Step-by-step explanation:

let the number

=

x

then 4 times the number

=

4

x

and 4 times the number increased by 15

=

4

x

+

15

also 6 times the number

=

6

x

and 3 less than 6 times the number

=

6

The average number of earthquakes that occur in Los Angeles over one month is 36. Assume the standard deviation is 3.6. if a ran
Ghella [55]

Answer: 0.9927

Step-by-step explanation:

We assume that  the number of earthquakes that occur in Los Angeles follows normal distribution.

As per given , we have

\mu=36\\\\ \sigma= 3.6

Sample size : n= 35

Let \overline{x} be the sample mean.

Now ,

P(34

Hence, the probability that the mean of the sample is between 34 and 37.5. is 0.9927 .

Consider the sequence of steps to solve the equation: 3(x − 4) + 5x = 9x − 36 Given ⇒ 3(x − 4) + 5x = 9x − 36 Step 1 ⇒ 3x − 12 +
7nadin3 [17]

In Step 6, the equation is ...

  -12 = x - 36

In step 7, the equation is ...

  -12 +36 = x -36 +36

Clearly, to get to step 7, 36 has been added to both sides of the equation.

Adding 36 to both sides of the equation is justified by ...

... C) Addition Property of Equality

_____

<em>More about the addition property of equality</em>

The addition property of equality says you can add the same value to both sides of an equation without changing the values of the variables that make the equation true. Here, x=24 makes the equation of step 6 true, and x=24 makes the equation of step 7 true.
