The equivalent expression using associative property is
<h3><u>Solution:</u></h3>
Given expression is [(5.3). 12]
We are asked to write a equivalent expression using associative property
The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis
<em><u>
Associative property is as follow:-</u></em>
a + (b + c) = (a + b) + c { for Addition}
(a x b) x c = a x (b x c) { for multiplication}
The given expression is [(5.3). 12], which can be written as
Answer:
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Answer:
D
Step-by-step explanation:
Let's find unit rate of each (number of miles traveled in 1 hour). For that we will divide the distance by time to get the unit rate.
Note:
(A)
rate = mph (miles per hour)
(B)
rate = mph
(C)
rate = mph
(D)
rate = mph
<u>As we can see, the first 3 rates are same, 75 mph, and the last one is mph. So clearly, the last rate is the slowest.</u>
D is the right answer.
A cell's expected frequency can be defined as the number of people in its row divided by the total number of people, multiplied by the number in its column and is therefore denoted as option C.
<h3>What is Frequency?</h3>
This is defined as the number of occurrences of a repeating which takes place per unit time.It also helps to measure how frequent something occurs when counted or observed and is also used in the calculation of the different types of statistical data present or given.
This type of frequency is theoretical and are values which will most likely be in an experiment. it is calculated by multiplying the number in its column by the number of people in the row and dividing by the total number of people in this context.
