Answer:
For this particular case they are interested on the amount of weight gained by randomly selecting some students, we need to remember that the weight can't be a discrete random variable since this random variable can take values on a specified interval and with decimals, so for this case the best conclusion is that we have a continuous data set.
Step-by-step explanation:
Previous concepts
We need to remember that continuous random variable mans that the values are specified over an interval in the domain, so is possible to have decimal values for the possible outcomes of the random variable.
By the other hand a discrete random variable only can take integers for the possible outcomes of the random variable over the specified domain.

Answer:
Step-by-step explanation:
You are going to want to use the compound interest formula, which is shown below.
<em>P = initial balance</em>
<em>r = interest rate</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
Since the balance is compounded quarterly, the number 
will be used for n.
Now lets plug in the values into the equation:
Given:
The area of the rectangle RSTU = 
Length of the rectangle RSTU = 
To find:
The width of the rectangle RSTU.
Step-by-step explanation:
We have,
Splitting the middle term, we get
We know that, the area of a rectangle is
Area of rectangle is product of (4x+5) and (9x-5).
Since (4x+5) is the length of the rectangle, therefore, (9x-5) is the width of the rectangle RSTU.
Answer:
7.5
Step-by-step explanation:
when we make a fraction percentage it is like this
3/40*100
Answer:
Value of x is greater than -8.
Step-by-step explanation:
Given:
5 - ( x + 5 ) > -2( x + 4 )
We need to find value of x.
Consider,
5 - ( x + 5 ) > -2( x + 4 )
using distributive property, we get
5 - x - 5 > -2x - 2× 4
5 - x - 5 > -2x - 8
Now simplify both side.
-x > -2x - 8
transfer -2x from RHS to LHS
-x + 2x > -8
x > -8
Therefor, Value of x is greater than -8.
