The answer would be -18/-7
a) x-intercepts (where it passes through the x-axis) are: 0.05, 0.745, 0.8, 1.45, 1.55, 2.2
The x-intercepts represent when height = 0 and y-intercepts represent when time = 0
b) The graph is positive when height is positive: [0.05, 0.745] U [0.8, 1.45] U [1.55, 2.2]
c) The graph is negative when height is negative: [0, 0.05] U [0.745, 0.8] U [1.45, 1.55] U [2.2, ∞)
d) The average rate of change is the slope (rise/run) between the coordinates when x = 0.75 <em>(y = -5)</em> and when x = 1.125 <em> (y = 1.7). </em>
slope = 
= 
= 6
Answer:
Undefined
Step-by-step explanation:
Slope is equal to the change in y over the change in x.
m = (y₂ - y₁) / (x₂ - x₁)
Let your points (5, 6) be (x₁, y₁) and (5,-8) be (x₂, y₂). Therefore you have
m = (-8 - 6) / (5 - 5) = -14 / 0
Dividing by zero will lead you to have an undefined slope
So this question can be representd by
eight times a number, (8x), is subtracted from (-8x) eleven times a number (11x), the result is -9
so -8x+11x=-9 or
11x-8x=-9
add like terms
3x=-9
divide both sides by 3
x=-3
Answer:
P( X ₙ ≤ 3) = e⁻³ [1+5+5²/2!+5²/3!]
Step-by-step explanation:
There are different way to solve it
Number of men and women entering are two separate Poisson random variable , with total number of people entering with rates being the sum of two. Poisson distributed with λ M
and for women
Poisson distributed with λ W
If we assume that men and women come in same rate then
λ M = λ W
But from the problem we see that
λ M + λ W = 10
M
≈Poisson{x;5}
P( X ₙ ≤ 3) = e⁻³ [1+5+5²/2!+5²/3!]
