Graphs are used to put numbers in a visual form, like a bar graph showing population growth over time. Their advantage is that it helps the viewer understand the situation by seeing it in a easier way.
Angle R is the reference angle as its the only given angle (other than the 90 degree angle).
Opposite angle R is segment PQ
PR is the hypotenuse
Use the sine rule to find that...
sin(angle) = opposite/hypotenuse
sin(R) = PQ/PR
sin(19) = PQ/11
11*sin(19) = PQ
PQ = 11*sin(19)
PQ = 3.58124969902872 <<-- use a calculator (degree mode)
PQ = 3.58
Answer: 3.58

Michelle opened her bank account on September 1st with $25 and continues to deposit $25 each month. Calculate the time Michelle will have a total of $500 in her account.
Answer:
19 months
Step-by-step explanation:
Initial deposit =$25
Monthly deposit = $25
Total deposit, y after x months can be modeled using the relation :
y = $25 + $25x
To have a total of $500 ; y = 500
$500 = $25 + 25x
$500 - $25 = $25x
$475 = $25x
x = $475 / $25
x = 19 months
Hence, Michelle will have deposited a total of $500 in his account after 19 months
Answer:
<h3>The purpose of a single linear regression is <u>
To predict a dependent variable from data from multiple independent variables</u></h3>
Step-by-step explanation:
The purpose of a simple linear regression is same as a correlation in that the purpose is to measure a linear relationship between two variables to the end.
In that particular case , its purpose is to "predict" the data from a dependent variable to the data from atleast one independent variable.
<h3>The purpose of a single linear regression is <u>
To predict a dependent variable from data from multiple independent variables</u></h3>
