To find the mean of a set of values, add the values and divide by the number of values.
mean = (sum of values)/(number fo values)
mean = (<span>80 + 95 + 100 + 85 + 95)/5 = 455/5 = 91
Answer: C. 91</span>
8.9 because you divide and multiply or u can just plug and chug
180/3 = 60
Therefore the car traveled 60km per hour.
Answer:
Point slope form
y - 9 = 4(x-1)
Equation of the straight line passing through the point (1,9) and slope 'm' = 4 is 4 x - y +5=0
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the points are (1,9) and (-1,1)
slope of the line

m = 
m = 4
<u><em>step(ii):-</em></u>
Equation of the straight line passing through the point (1,9) and slope 'm' = 4
y-y₁ = m( x-x₁)
y - 9 = 4(x-1)
y -9 = 4x-4
4 x - y -4+9 =0
4 x - y +5=0
Equation of the straight line passing through the point (1,9) and slope 'm' = 4 is 4 x - y +5=0
