In Polynomials all the exponents of x-variable must be positive integers, then polynomials are:
<span>a) -x^5+7x-1/2x^2+9, the exponents of x's are: 5, 1, and 2
b) x^3-4x-3, the exponents of x's are: 3, and 1
f) x^4+x^3√7+2x^2-√3/2x+π, the exponents of x's are: 4, 3, 2, and 1
Not polynomials are:
</span><span>c) 4 / x^2-4x+3 = 4x^(-2)-4x+3, the exponents of x's are -2, and 1
d) x^4+5/x^3-√x+8=x^4+5x^(-3)-x^(1/2)+8, the exponents of x's are 4, -3, and 1/2
e) </span>|x|^2+4√x-2=<span>|x|^2+4x^(1/2)-2, the exponents of x's are 2 and 1/2</span>
The bill was actually $25 and the waiter kept $2 so 25 + 2 = $27
$27 / 3 people = $9 per person.
They each originally paid 10, but were given 1 back: 10 - 1 = 9, so they each ended up paying $9 each.. there is no extra dollar.
The probability that she will obtain a scholarship given that she is accepted by the college is 0.54.
Given that the probability that Samantha will be accepted by the college of her choice and obtain a scholarship is 0.35, to determine, if the probability that she is accepted by the college is 0.65, the probability that she will obtain a scholarship given that she is accepted by the college, the following calculation must be performed:
- 0.65X = 0.35
- X = 0.35 / 0.65
- X = 0.538
Therefore, the probability that she will obtain a scholarship given that she is accepted by the college is 0.54.

Answer: Hence, Probability of more than 1 death in a corps in a year is 0.126.
Step-by-step explanation:
Since we have given that
Mean for a poisson distribution (λ) = 0.61
Number of years = 20 years
We need to find the probability of more than 1 death in a corps in a year.
P(X>1)=1-P(X=0)-P(X=1)
Here,
So,
P(X>1)=1-0.543-0.331=0.126
Hence, Probability of more than 1 death in a corps in a year is 0.126.
