Answer:
B. Survey 1,000 people aged below 25 who read newspapers
Step-by-step explanation:
It's the youth in the community so it's obviously people below 25 and we need more responses to get a more unbiased opinion.
Answer:
Remember rise over run for the slope.
the slope is always the number on the left side (x) and the y intercept is the number in the right (y)
(x,y).
Let the unknown number be x.
x × -7 = 7 (x + -40)
-7x = 7x - 280
-14x = -280
x = 280/14
x = 20
Hope this helps!
Answer:
(a) 3
Step-by-step explanation:
Calculate the slope m of the line given using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0,3) and (x₂, y₂ ) = (3, 2)
m =
= - 
given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 3 → (a)
