Answer:
On the Scatter Plot, the two variables associated with each other when represented in Quantitative form that is in the form of x-values and y-values, it can be drawn in two dimensional coordinate plane, Representation being a line.
1.The Line may pass through all the points , a single point or none of the points.
2. It can also predict the future values that is for given x , we can find y and for given y , we can find x.
So, only option (4) which is,Scatter plots can be used to represent quantitative data is true.
Answer:
a convenience sample is always valid and reliable is true not false
Step-by-step explanation:
Answer:
2000 people
Step-by-step explanation:
The area of the gym is the width times length:
A = wl
A = (50 ft) (100 ft)
A = 5000 ft²
Write a proportion:
1 person / 2.5 ft² = x / 5000 ft²
x = 2000 people
X would be the absolute value of 10 or -10 since they both are 10 units from 0 so it can be x=l10l or x=l-10l, they both equal 10
