Answer:
QS = 17 units
Step-by-step explanation:
Given:
R located at QS
QR = 10
RS = 7
Find:
Measure of QS
Computation:
QS = QR + RS
QS = 10 + 7
QS = 17 units
Answer:
predicted GPA=9.21, residual= 1.36, a correct value of slope would be 0.09
Step-by-step explanation:
y=0.1x -3.49
y: GPA
x: IQ
y=0.1(127)-3.49
y= 9.21
Predicted GPA= 9.21
residual= 9.21- 7.85= 1.36
The equation doesn't model the exact relationship between GPA and IQ.
A better slope value could be
7.85= m(127)-3.49
m=0.09
<u>Answer:</u>
gradient = =
y-intercept =
<u>Step-by-step explanation:</u>
• The slope-intercept form of an equation takes the general form:
,
where:
m = slope,
c = y-intercept.
• We are given the equation:
To change this into the slope-intercept form, we must make y the subject:
[subtract from both sides]
⇒ [divide both sides by 3]
⇒
• Comparing this equation with the general form equation, we see that:
m =
c = .
This means that the gradient is , and the y-intercept is .
Y= (amplitude).sin(2π/period).(x-shift)
= 2.sin(2π/π)(x-π)
=2.sin[2.(x-π)]
