Answer:
B and D
Step-by-step explanation:
to calculate the slope m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
(4)
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (3, - 1) ← 2 points from table
m = = = 1 → B
(5)
with (x₁, y₁ ) = (- 1, - 4) and (x₂, y₂ ) = (2, 5) ← 2 points from table
m = = = 3 → D

Solution:
Rate of change = Slope between two points
Rate of change of two points is given by=

Answer:
40%
Step-by-step explanation:
to find a percent you would take the full sum (525) divided by the smaller number (35 times 6) which will get you 0.4 which is 40%
Answer:
P(B) = 0.62
Step-by-step explanation:
<u><em>P(A or B) = P(A) + P(B) - P(A and B)</em></u>
<em>So, Putting the givens</em>
0.89 = 0.48 + P(B) - 0.21
0.89 = 0.27 + P(B)
P(B) = 0.89 - 0.27
P(B) = 0.62
