First you turn 16 to 0.16 then multiply 0.16 x 75 and you should get 12
I hope this helps you and your welcome : )
Answer:
x = -1, y = 1
Step-by-step explanation:
Multiply the top equation by 2:
Leaving the bottom equation unchanged, add the two resulting equations to eliminate y, obtaining:
Solve this for x, and then substitute this value of x into the bottom equation. Finally, solve for y.
Answer:
D
Step-by-step explanation:
In this question we are asked to pick the correct option that clearly states what statisticians use linear regression for.
To answer this question, I shall be considering the validity of the options one after the other.
But before that , what is a linear regression model?
A linear regression model employs a linear plot to explain the relationship between a dependent variable and another variable called the independent variable.
Option a is wrong.
A regression model does not say if the dependent and independent variables match
Option B is wrong
A linear regression model cannot be used to predict the value of an unknown dependent variable from the unknown Independent variables. X is the independent here with y the dependent
Option C is wrong
Since Y scores is known, then what are we predicting again?
Option. D is correct
We predict values of the unknown dependent variable y from the known independent variable x
Given :
A submarine started at the surface of the water and was moving at -15 meters per minute.
The submarine traveled at this rate for 48 minutes before coming to rest on the ocean floor.
To Find :
The change in the submarine position.
Solution :
We need to find the position of submarine position from the surface of water.
Distance travelled = Speed × Time
Distance travelled = -15 m/min × 48 min
Distance travelled = 720 m
Therefore, the position of submarine is 720 m below the surface of ocean.
