Answer:
x^2 (12 x - 5)
Step-by-step explanation:
Simplify the following:
12 x^3 + (2 x x)/2 - 6 x^2
(2 x x)/2 = 2/2×x x = x x:
12 x^3 + x x - 6 x^2
x x = x^2:
12 x^3 + x^2 - 6 x^2
x^2 - 6 x^2 = -5 x^2:
12 x^3 + -5 x^2
Factor x^2 out of 12 x^3 - 5 x^2:
Answer: x^2 (12 x - 5)
Answer:
15
Step-by-step explanation:
Where n represent no.of sides
(2n-4)90=2340
180n-360=2340
180n=2340+360
180n=2700
n=15
Answer:
89percent
Step-by-step explanation:
i am not good at math but what ever
The total of the road is 4800 m long. 4800-1440=3360m
We subtract what they have yet to cover from the total to get what they have covered.
So in 30 days they covered 3360 metres.
3660/30 (3660 is divided into 30 equal groups) = 122m
On average they covered 122 metres per day.
Answer:
a) 0.122
b) 3.35 × 10⁻⁴
c) 0.1071
Step-by-step explanation:
Here we have the Poisson process given by
Where:
λ = Rate = 4 bites/hour and
t = Length of time that is
Mean = λt
Where k = 6 fishes bites and t = 2 hours we have
b) The probability that he fails to catch any fishes during the first two hours is the probability t that he catches 0 fish as follows
(c) Here we have
For 1 fish caught in two times we have first time no fish and second time he caches a fish gives
0.122×(1-0.122) = 0.1071
