Answer:
x = -4/45
Step-by-step breakdown:
180x=2(30÷3)+17-5•11+2÷1
We first need to simplify the right side. The initial step involves the parentheses
180x=2(10)+17-5•11+2÷1
Next, we multiply and divide, proceeding from left to right after the equals sign.
180x=20+17-5•11+2÷1
180x=20+17-55+2÷1
180x=20+17-55+2
Next, we add and subtract, moving from left to right in relation to the equals sign.
180x=37-55+2
180x =-18+2
180x = -16
Then divide each side by 180
180x/180 = -16/180
x = -4/45
Answer:
y = 2.09x^2 + 0.33x + 3.06
Detailed explanation:
<span>The likelihood of both selected students being sophomores is 6/20, which simplifies to 3/10.
The expression for the probability that both chosen students are sophomores is (6c1) (5c1) /(20c2)

Answer:
0.047
Detailed breakdown:
Using a Poisson distribution with a mean m, for an area of 0.5 square meters = 1.5
The formula to determine the probability is given by
P[k] = (e^-m * m^k) k!
Thus, we can calculate
P[4] = [(e^-1.5) * (1.5^4)] ÷ 4 * 3 * 2 * 1
= (0.2231301601 * 5.0625) ÷ 24
= (1.12944375) ÷ 24
≈ 0.04706
≈ 0.047
Therefore, the final result is 0.047
