Step-by-step explanation:
Answer: C
Explanation: It would be c because, there is no certain time it takes to take a shower.Someone could take a shower for a hour or 10 minutes.
Continuous Data means there is no set or certain time.So like a shower, you can take however long you want.
Answer:
9x+5y=-45
Step-by-step explanation:
To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:
Now that we have the slope, plug in the slope and choose one point to plug into the point slope formula. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-0)=-9/5(x--5)
y=-9/5(x+5)
y=-9/5x-9
Now convert to standard form, Ax+By=C.
y=-9/5x-9
9/5x+y=-9
9x+5y=-45
180 ÷3 = 60 ° (angles on a straight line equals to 180 ° )
a+b+60 =180°
a+ b= 180 ° - 60° = 120°
(a+b) are 2 variables
so 120 ÷2 =60 °
therefore a and b =60 °
c +b+ 60° = 180° ( co - interior angles are supplementary angles )
c+60° +60° =180°
c +120° =180°
c =180°-120°
c=60 °
d=60° (alternate angles are equal )
or
c+b+d=180°
60° +60° + d = 180°
d=180°-120°
d=60°
