Yes, In Descriptive Statistics we are most often interested in the summary of data in words. It is done by describing the features of the data. Mostly we explain the five-number summary of the data, central tendency of data, dispersion, skewness, etc. Overall we summarize the quantitative data in words.
Answer:
<h2>30</h2>
Step-by-step explanation:
<h3>to understand the steps</h3><h3>you need to know about:</h3>
- system of linear equation
- word problems
- PEMDAS
first step
let's create the equation word problem
<h3>my mother's current age is four times the sum of the ages of my two sisters. After 5 years, my mother's age will be double the sum of the ages of my two sisters. What is the current age of my mother? (imaginary problem)</h3>
let's solve
let my mother's and sister's age be x and y respectively
according to the first condition,x=4y....(I)
according to the 2nd condition,x+5=2(y+5×2).....(ii)
so the system of linear equations is
x=4y
x+5=2(y+5×2)
gets from the second equation
x+5=2(y+10)
x+5=2y+20
4y+5=2y+20 (as x=4y)
2y=15
y=7.5
so the age of mother is
x=4.(7.5)
x=30
Your answer is 12 using PEMDAS.
Divide 32/8=4
4+8=12
This is what you do. You multiply 1/10 and 40. Like this: 1/10 x 40/1
