Answer:

Step-by-step explanation:





Since they are independent events to find the probability of both is P(A) * P(B)
P(A) = P(Heads) =

P(B) = P(Roll ≥ 4) =

Now multiply those fractions together

= P(Heads & ≥ 4)
Factor completely x³ + 6x² - 3x – 18

with a root of x = -6
the answer is 210
Answer:
x = 6, y = -2
Step-by-step explanation:
24/4 = 6
x = 6
= (5x6)+8y=14
= 8y = 14 -30
8y = -16
y = -16/8
y = -2
Check: 5x6+8x-2= 14
Firstly, the rate of increase of Canton = 80/7720 = 0.010
The rate of increase of HP = 120/3200 = 0.0375
Apply the formula of compound interest==> A =A'(1+i)^n
The population will be equal when the following equality is satisfied
7720(1+0.01)^n = 3200(1+0.0375)^n
or
7720x1.01^n = 3200x1.0375^n
Divide both sides by 3200 ===>(193/80)x1.01^n=1.0375^n
