- Increasing heart rate
- positive correlation
Kid / adults can get confused on a question that is why you should always try to word it the right way that u think kids / adults would understand
I'm not positive of this answer but, I'm pretty sure it's 85,688 using common sense. The population would definitely be greater before the epidemic hit because, and infectious disease or anything like that would obviously cause the population to decrease. Therefore, B) is the most reasonable answer.
Answer:
Option D
Step-by-step explanation:
Rate of change of a linear function between two points and is given by,
Rate of change 'm' =
From the given table,
Rate of change of the function between (-2, 6) and (-4, 9),
Rate of change 'm' =
m =
Initial value = y-intercept
Let the equation of the line passing through a point (h, k) is,
y - k = m(x - h)
If a point (-2, 6) is lying on the graph of the function,
y - 6 =
y =
y =
Y-intercept of the function = 3
Therefore, initial value of the function = 3
Option D is the answer.
Answer:
P = 0.5Q - 20
Step-by-step explanation:
P = kQ + c
substitute Q = 60 , P = 10 into the equation
10 = 60k + c → (1)
substitute Q = 240, P = 100 into the equation
100 = 240k + c → (2)
subtract (1) from (2) term by term to eliminate c
90 = 180k ( divide both sides by 180 )
= = 0.5 = k
substitute k = 0.5 into (1) and solve for c
10 = 60(0.5) + c
10 = 30 + c ( subtract 30 from both sides )
- 20 = c
then
P = 0.5Q - 20
