F(t)
= t2 + 4t − 14
y + 14 + 4 = (
t2 + 4t +4)
y + 18 = ( t +
2)^2
so the vertex
of the parabola is ( -2 , -18)
<span>the axis of
symmetry is y = -18</span>
So puppies will be 5x and Kittens 4 x so they combined will be 5x+4x=27
9x=27
X=3
Answer:
7
Step-by-step explanation:
135 = 15*(x+2)
X+5=2x-7
x=12
y=12+5
y=17
(12, 17)
Answer:
0.19975
Step-by-step explanation:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
Given:
n = 11
r = 9
p = 0.7
q = 0.3
Plugging in values:
P = ₁₁C₉ (0.7⁹) (0.3¹¹⁻⁹)
P = 0.19975
